Automatic Forming Technology of Resin Sheet Grinding Wheel

Design principles seem to be very effective in improving production efficiency. But there is a practical problem is that no matter how adjusted, always reach the ideal level of design. Because the thin grinding wheel material is not like smelting corundum, silicon carbide, raw materials, the error can not be too large, through the conveyor belt feeding, in order to accurately weighing is not an easy thing, repeated adjustment, not only can not improve efficiency, but wasted a lot of time. Now is a compromise approach to bypass the more difficult feed system, artificial feed, with multi-station press, reduce labor intensity, production efficiency can be guaranteed.

The ideal feed system has yet to be improved and developed. This technology, once mastered, will enable the production of thin-sliced grinding wheels as well as the production of coated abrasives, efficient, fast, fully mechanized and automated, bringing dramatic changes to the sheet market .

Grinding wheel using in Abrasive

Grinding wheel, also known as fixed abrasive, is the bond will be ordinary abrasive consolidation into a certain shape (most of the circular, the central through hole), and has a certain strength of the bonded abrasive. It is generally composed of abrasive, bonding agent and porosity, these three parts are often referred to as the three elements of the bonded abrasive tools. According to the different classification of the bond, the common ceramic (bond) grinding wheel, resin (bond) grinding wheel, rubber (bond) grinding wheel.

The Grinding Wheel is one of the largest amount of abrasives, widely used, when using high-speed rotation can be cylindrical, metal or nonmetal workpiece inner circle, plane and various surface of rough grinding, semi fine grinding and fine grinding and notching and cutting etc.. The characteristics of the grinding wheel are mainly determined by the factors such as abrasive, grain size, bond, hardness, structure, shape, size and so on.

Grinding wheel axis and workpiece axis should be so high to ensure that the spherical roundness. Grinding patterns are usually used to determine the contour of the error. If the grinding sphere surface was convex pattern, indicating that the grinding wheel to participate in the lower half of the grinding, the center of the wheel below the center of the workpiece, this time, the center wheel should be adjusted to make the center of the workpiece height, until the mill The surface of the sphere is cross-shaped. The error requirements in 0.003-0.004mm within.

Grinding outside the sphere, the wheel frame to turn a certain angle, so the wheel bore size of the dressing should be completed before the adjustment of the machine. Grinding wheel in the grinding process, do not need to dress the hole, as long as the end of the grinding wheel with sand dressing can be, so that both the grinding wheel to restore sharp, but also to ensure that the wheel bore size unchanged. Grinding wheel after grinding in a timely manner in order to facilitate the processing to ensure quality. As the spherical grinding wheel axis and workpiece axis can not be absolutely equal, so the workpiece will have a small step, affecting the accuracy of the workpiece, this time, the top of the spherical drill a hole less than 1mm to avoid.

Tool materials commonly used in tool grinding include high speed steel (HSS), powder metallurgy high speed steel (PM-HSS), cemented carbide (HM) and PCD, CBN, cermets and other superhard materials. High-speed steel cutting tools sharp, good toughness, carbide hardness but toughness is poor. Carbide tool density significantly higher than high-speed steel cutting tools. The two materials are the main material for bits, reamers, milling cutters and taps. Powder metallurgy high-speed steel properties between the above-mentioned between the two materials, mainly used in the manufacture of rough milling cutter and tap.
High-speed steel tool material due to good toughness, so the collision is not sensitive. However, carbide cutting tools, high hardness and brittle, very sensitive to the collision, the edge easy to jump. Therefore, in the grinding process, must be on the operation of carbide cutting tools and placed very carefully to prevent the collision between the tool or tool drop.
As the high-speed steel cutting tools are mostly relatively low precision, the grinding requirements are not high, coupled with its price is not high, so many manufacturers set their own tool shop grinding. Carbide tools, however, often need to be sent to a professional grinding center for grinding. According to Arnold tool grinding center statistics, more than 80% of the tool repair tool is carbide.
Second, the tool grinder
As the tool material is very hard, so the general can only use grinding to change its shape. In the tool manufacturing, grinding in the common tool grinding machine has the following:
Grinding machine: Grinding drill, milling cutter and other tools of the groove or back.
2. Grinding angle machine: grinding cone cone angle (or eccentric rear angle).
3. Repair the edge of the machine: the amendment of the cutting edge of the drill.
4. Universal universal tool grinding machine: grinding cylindrical, groove, back, vertex, horizontal blade, plane, rake face and so on. Commonly used in a small number of complex shape of the tool.
5.CNC grinder: generally five-axis linkage, function determined by the software. Generally used for grinding a large number of high precision, but not complicated tools, such as drill, end mills, reamers and so on. The main suppliers of such grinders come from Germany, Switzerland, the United States, Australia and Japan.
Third, grinding wheel
Abrasive grain
Different grinding wheel material is suitable for grinding different materials of the tool. Different parts of the tool need to use the size of the abrasive particles are different to ensure that the edge protection and the best combination of processing efficiency.
Alumina: Used for grinding HSS tools. The grinding wheel is inexpensive and easily modified into a variety of shapes for grinding complex cutting tools (corundum).
Silicon carbide: used to correct CBN grinding wheel and diamond grinding wheel.
CBN (cubic boron carbide): used for grinding HSS tool. The price is high, but durable.
Internationally, the grinding wheel with B to represent, such as B107, where 107 represents the size of the abrasive grain diameter.
Diamond: used to grind HM tool, the price is high, but durable. D on the wheel to that, such as D64, where 64 represents the size of the abrasive grain diameter.
2. Shape
To facilitate the grinding of different parts of the tool, grinding wheels should have different shapes. The most commonly used are:
Parallel grinding wheel (1A1): grinding angle, diameter, back and so on.

Characteristics of Centerless cylindrical grinding

    1. Two-wire External Grinding center hole does not play, do not support the workpiece thimble. Since the center of the workpiece uncertain, the grinding allowance is relatively reduced.
      2. External grinding mill can not axially grooved workpiece, grinding perforated workpiece, does not correct the position of the hole axis, low concentricity of the workpiece.
      3. Cut inside his cell under normal circumstances can only be processed on a roller rolling on the workpiece can therefore, particularly suitable for grinding sets of groups, and other thin-walled parts. Grinding sets of parts because the parts are positioning themselves cylindrical reference. Therefore it can not be corrected within the original uranium with external error between.

      4. Centerless grinding time maneuvering and loading and unloading time coincidence, easy to implement grinding process automation, high production efficiency.
      5. In the centerless grinding process, the change in position of the workpiece center depends on the size of the original error of the workpiece before grinding, process system rigidity, grinding, dosage and other process parameters (high workpiece center, pallets angle, etc.);
      Stability 6 centerless grinding movement of the workpiece, the machine depends on the uniformity of the transmission chain, the workpiece shape, weight, guide wheels and supporting materials, surface morphology, grinding with a star and other process parameters.
      7. Centerless grinding machine for a long time to adjust, to adjust the machine's technical requirements are also higher, does not apply to single and small batch production.

Resin grinding wheel cleaning method
    In the production process to use diamond grinding wheel grinding in the belt. General grinding wheel running 5-7 days to remove the cleaning. (Rubbed down above the rubber debris, after high temperature friction attached to the surface of the diamond, it is difficult to clean)
    Now we use acetone soak 2 hours, and then use imported cleaning agent cleaning, the effect is very good, but not environmental protection, energy saving.
    Cleaning requirements:
    1, to be environmentally friendly, non-ketone, can not be halogenated hydrocarbons.
    2, can not damage the diamond wheel tablets
    Installation Notes
    Grinding wheel in the installation must be carefully examined and identified before. Check the identification of the steps are:
    1, check whether the brand wheel is correct, in line with the performance of all selected grinding wheel, shape and size.
    2, check and identify the appearance of the wheel structure. Look at the wheel to see if it is damaged (or cracked). The appearance of damage (or cracks) of the wheel can not be used. There are also requirements both sides of grinding wheel flat, no obvious skew.
    3, check and identify the internal cracks in the grinding wheel. With a hand wheel, with a wooden hammer tapping wheel tablets listen to the sound, no crack of the grinding wheel issued a crisp sound, cracked wheels are hoarse voice, which can not be used.

2016年10月8日星期六

The grinding wheel is used to increase the production efficiency

Wide wheel grinding is also a kind of efficient grinding, is to increase the grinding width to improve the grinding efficiency: - 'external grinding width is only 50mm, and wide grinding wheel external grinding wheel width up to 300mm. Surface grinding wheel width up to 40mm, centerless grinding wide wheel width up to 800-1000mm; in the cylindrical and cylindrical grinding generally used in the cutting force cutting method, they are used in addition to the heartless grinding method, but also through Grinding wide grinding wheel grinding workpiece size accuracy up to 6, the surface roughness up to 6 Ra0.06um.

1. Grinding automotive parts - camshaft and crankshaft

The camshaft of automobile engine has a number of cams. The coarse grinding and fine grinding of the cam after hardening is the key process which affects the cam quality. Usually by the use of simulation-shaped grinding, the workpiece speed limit is limited, the workpiece is easy to produce grinding burns crack, the use of analog-shaped grinding, the cam surface contour curve wheel diameter affected by the size, it is difficult Make sure the cam profile is correct. Production practice shows that when the wheel diameter is large, the grinding out of the cam thin, when the wheel diameter is small, grinding the cam fat, only when the grinding wheel diameter close to or equal to the cam roller diameter (usually φ570mm) The profile error is close to zero, that is, the grinding cam surface contour curve close to the cam cam. In actual production, the wheel diameter used is generally from D600 (or 610) to D500, and the ideal wheel diameter (570) a lot of difference, so the total camshaft in most of the cam curve exceeded. To solve this problem, we rely on the grinding cam on the use of CBN grinding wheel grinding, CBN wheel diameter can be made D575, CBN abrasive layer thickness of 4 ~ 5mm, the grinding wheel diameter is the minimum D565, grinding diameter Although the scope of only 10mm, but the number of grinding parts is equivalent to dozens of ordinary wheel, not only to ensure the correct cam curve, but also does not produce grinding burns.

Such as Liton industrial automation company with CBN wheel grinding camshaft, the cost is reduced by 50%, the cam surface fatigue strength increased by 30%; Dongfeng Motor Company Xiangfan diesel engine plant with ceramic bonding agent CBN grinding wheel coarse grinding chilled cast iron camshaft , The cam grinding margin t = 4 ~ 5mm, υ sand = 60m / s, the workpiece speed n = 100r / min, υf = 0.1mm / s, using high-speed grinding fluid, CBN grinding wheel life is basically equivalent to 20 Corundum abrasive wheel.

Applications of Diamond Grinding Wheel

Metal and non-metallic hard and brittle material is widely used in ordinary abrasive difficult to process low iron content, it is widely used in optical processing, sapphire, watches lenses, glasses, glass, precision ceramic, ferrite, automobile and motorcycle, beauty , aviation, military, cutting tool industry. Such as cemented carbide, alumina ceramic, optical glass, agate gem, semiconductor materials, stone and the like.

So far only ceramic bond diamond wheel can be trimmed on the machine. When using such a grinding wheel, worn too much and the feed rate is too low. Recently, however, there is a resin bonded grinding wheel groove, both with high material removal rate can be trimmed on the production equipment.

2016年9月28日星期三

Take minor trim

In order to reduce the dressing time, as if there is always want to choose a larger repair depth of the temptation. This is a very wrong idea. You must choose the most appropriate repair depth of the wheel dressing. Choose too much repair depth, will have a high cutting temperature, reducing the life of the dresser, but also useful to remove the wheel layer. The end result is that both the dresser and the grinding wheel are damaged and counterproductive. The best dressing quantity is the rule that can restore the grinding wheel geometry and produce good grinding edge after repairing several times.

Use a single-point dressing tool, should be 10-15o of the axis of the angle of contact with the grinding wheel diameter direction. This will allow the single-point dressing tool to produce a sharpened effect when rotated periodically. The trimming tool with multi-point contact does not need to be tilted at this angle. With the entire end face of the dressing tool being in contact with the surface of the grinding wheel.

The traverse speed is the speed at which the dressing tool passes through the surface of the grinding wheel during dressing. It requires the processing of surface roughness and metal cutting rate are played a key role. Lateral movement too slow will clog the wheel and damage the part's surface roughness and metal-cutting rate. Too slow the traverse speed can also cause the grinding wheel to vibrate and burn the part surface. Even faster horizontal movement speed can repair a good grinding wheel surface to improve the grinding performance of grinding wheel to increase the grinding efficiency and reduce part surface roughness.

2016年9月27日星期二

End face of the grinding wheel - Repair

After forming,grinding wheel end there may be some shortcomings, so to repair, due to the different abrasives, repair methods will be different, so we should take a different approach for different abrasive, then, we have to introduce how three different abrasive grinding wheel is carried out to repair:
First, the type of abrasive corundum, and this wheel is usually not needed trimming, by self-sharpening wheel to fall off the sand, ongoing appropriate compensation it. That is up to the new wheel in the beginning, in order to balance a simple tidy up.

Second, diamond abrasives, such grinding wheel dressing wheel dressing pen can not use, but to rely on a little soft, sticky bigger things to be trimmed, for example, A3. Iron, stone and so on.
Third, CBN abrasives, which can refer to the second wheel dressing wheel dressing mode.

Grinding Wheel life and Criterion

The actual time of the grinding wheel dressing between the two is called the wheel life. Analyzing wheel life, generally based on the phenomenon of post-Face wear produced by visual determination. The main phenomenon: grinding process appears self-excited oscillation, the surface appears regeneration chatter; grinding noise increases; the workpiece surface burn appeared grinding, grinding force a sharp increase or decrease; loss of precision grinding; grinding surface rougher. The phenomenon is mainly due to the high temperature of grinding the workpiece surface roughness and precision and thermal damage due to the degradation caused by self-excited vibration.

Wheel End of life form: the wheel surface passivation - polished state (to increase the grinding force and grinding heat); wheel loading (prone to vibration or noise until burns); grinding wheel contour damage (machining accuracy)

What Are Superabrasives?

Superabrasives make up a special category of bonded abrasives designed for grinding the hardest, most challenging work materials.

Because carbides, high speed steels, PCD, PCBN, ceramics and some other materials used to make cutting tools can be nearly as hard as conventional abrasives, the job of sharpening them falls to a special class of abrasives-diamond and the CBN, the superabrasives.

These materials offer extreme hardness, but they are more expensive than conventional abrasives (silicon carbide and aluminum oxide). Therefore, superabrasive grinding wheels have a different construction than conventional abrasive wheels. Where a conventional abrasive product is made up of abrasive all the way through, superabrasive wheels have abrasive on the cutting edge of the wheel that is bonded to a core material, which forms the shape of the wheel and contributes to the grinding action.

Superabrasive wheels are supplied in the same standard grit range as conventional wheels (typically 46 through 2,000 grit). Like other types of wheels, they can be made in a range of grades and concentrations (the amount of diamond in the bond) to fit the operation.

There are four types of bond used in superabrasive wheels. Resinoid bond wheels are exceptionally fast and cool cutting. They are well-suited to sharpening multi-tooth cutters and reamers, and for all precision grinding operations. Resin is the "workhorse" bond, most commonly used and most forgiving. Vitrified bond wheels combine fast cutting with a resistance to wear. They are often used in high-volume production operations. Metal bond wheels are used for grinding and cutting non-metallic materials, such as stone, reinforced plastics and semiconductor materials that cannot be machined by other cutting tools. Single-layer plated wheels are used when the operation requires both fast stock removal and the generation of a complex form.

Structures Of Diamond Grinding Wheel

Diamond grinding wheel is suitable for a variety of materials forage to concentrate grinding surface grinding, cylindrical grinding, internal grinding, and cutting. For example: carbide, ceramics, magnetic materials, tungsten steel, semiconductors, glass, gemstones.

The structure of gridning wheel generally consists of the active layer, the substrate, the buffer layer consists of three parts.

1, the working layer, also known as diamond layer, made of abrasive, binder and filler, is working part wheel.

2, also known as non-diamond layer, transition layer, the binding agent, metal powder and a filler, is fixedly connected to the part of the diamond layer on the substrate.

Our large supply of diamond, CBN grinding wheel, disc, cutter. My company has advanced production and processing equipment, strong technical force, strict means testing. All products produced in accordance with national standards.

3, the substrate for receiving the abrasive layer and the use of securely held on the grinding machine spindle flange. General metal binding agent selected steel products, alloy powder as a matrix;

Resin binder be aluminum, electrical wooden base. It made of aluminum, steel or bakelite processing, support from the working layer and chucking abrasive effect.

The quality of the grinding wheel molding and use of precision level and the substrate are a great relationship. When using a diamond grinding wheel drill trench requires a higher feed rate. In order to ensure a high feed rate, cutting sharp require binding agent system.

Vibration is an enemy of finishing

In grinding wheel dressing, effectively reduce the vibration, to avoid the grinding wheel surface traces of finishing, collisions and damage repair tools, etc, is crucial. This means that also must be a balance of grinding wheel, which is decided by the structure characteristics of the grinding wheel itself. The stand or fall of uneven density and the wheel geometry, will affect the natural balance of a grinding wheel. So choose a high quality of the grinding wheel is also very important. If is a high quality of the grinding wheel, the proper installation which can keep balance of grinding wheel is very good. According to the grinding wheel manufacturer factory instructions, grinding wheel with an up arrow, which shows the light while the wheel after rough balance. Root tree arrows, then the user can pay attention to dressing grinding wheel, make its reach dynamic equilibrium. Cooling fluid filling evenly, sometimes can also help the wheel balance.

As much as possible in order to prevent vibration, the operator will make dressing tools strong ground clamp on the holder and have the smallest trailer, only in this way can make the dressing tool has a strong enough rigidity. If the diamond tool in the process of finishing not firm clamping, hard to avoid can cause serious noise, vibration, make the surface of the parts produced tiny ripples, the surface strain of the parts and cause some damage for dressing tools.

Diamond magnetic susceptibility measurement is to measure the magnetization of the diamond sample. Diamond is composed of carbon atoms, pure diamond should not sense the magnetic, since the diamond used for the synthesis of metal as catalyst, a synthetic diamond interior containing various amounts of metal impurities, especially the inclusion within the crystal resulting diamond has a magnetism, and therefore , synthetic diamond magnetic size, not only its internal impurities and inclusions content component has a direct relationship, but also with its physical and chemical properties and quality indicators (such as toughness, strength, specific gravity, thermal stability, color, transparency, etc.) there is a close relationship. By measuring the magnetic susceptibility of this simple way of non-destructive testing, characterization of the nature of the impurities in synthetic diamond, toughness, strength, thermal stability, etc., has important practical value. Generally the lower the susceptibility of the diamond, the less impurities in diamond, the toughness better, better transparency, and wear properties of diamond tools is better. Some large foreign companies have internal susceptibility tests as an indicator to control the quality of diamond.

Vibration is the enemy of dressing

In the wheel dressing, and effectively reduce vibration and avoid dressing in grinding wheel surface leaving traces of collision and damage repair tools, it is essential. This means that you must also maintain a balance wheel, which is the wheel itself, the structural characteristics of the decision. Density unevenness and the entire wheel geometry is good or bad, will affect the natural balance of a wheel. So choose a high-quality grinding wheel is also very important. If it is a high quality grinding wheel, just proper installation that is able to maintain a good balance wheel. Grinding wheel according to the manufacturer's instructions factory, are marked with an arrow up on the wheel, it shows the balance wheel after crude light end position. The user can then noted in the arrow directions, wheel dressing attention to dynamic equilibrium. Coolant uniformly filling, and sometimes can also help maintain a balance wheel.

In order to prevent vibrations as much as possible, the operator must make the dressing tool clamped in strong clip seat and leave the minimum amount of overhang, the only way to make the dressing tool strong enough rigidity. If diamond tools are not firmly clamped in the finishing process, it will inevitably cause vibration, resulting in severe noise, the surface of the part produce small ripples, resulting in parts of the surface strain on the dresser and cause some damage.

Keep them cool

Proper use of coolant, can speed up the repair and improve the efficiency of trimming. According to experience, a 3/8 of an inch of the diameter of the cooling fluid, can eliminate a lot of heat from the dresser, prolong the service life of the dresser. When diamond dressing tools by grinding wheel, install a cooling fluid nozzle, full of the grinding wheel surface or constantly refill coolant to diamond dressing tools. After the dressing tool and start dressing grinding wheel contact, never allow dressing tools, exit from the cooling fluid. Otherwise it will make diamond dressing tools, under the extreme temperature of cold and hot, crack or break.

Use filters to high precision filter, coolant can avoid dirt or chip in the cooling liquid cycle for many times. Contaminated coolant can make grinding wheel wear quickly, to increase the number of grinding wheel dressing. Only when dry grinding (only in this case, can interrupt cooling) for diamond dressing tools, grinding wheel to take dry finish. In every day before coming off work, after turn off the cooling fluid, let the grinding wheel idle for a few minutes. This will prevent broken wheel.

The balance of grinding wheel

The replacing of Grinding Wheels

Advances in resin grinding wheel processing

In the current gear grinding, still in use by ordinary abrasive. But the standard abrasive and aluminum oxide ceramic product productivity has been greatly improved. Sintered ceramic and single crystal aluminum oxide, synthetic binder, and the development of new grinding technology, this progress has contributed.

In the last 10 years, more and more people use powerful creep feed grinding mode processing involute. Compared with the hitherto conventional reciprocating grinding, grinding wheel contact area is much greater, therefore, the use of the wheel must be able to withstand high pressures. Only when subjected to a sufficiently high pressure on a single abrasive grit it may become a pointed.
