Wheel knowledge




A wheel attribute categories



      
There are two characteristics determine the type of grinding wheel:



 
1.
From the material is divided, namely products used abrasive. Abrasive wheel determines the performance of different abrasive, apply the best wheel
Range has changed. Specific points, abrasives are the following: corundum abrasives, abrasive corundum, chromium corundum abrasives, single
Abrasive grain corundum, black corundum abrasives, abrasive silicon carbide green and black silicon carbide abrasive, micro-porosity wheel, grinding wheel small pores, atmosphere
Hole wheel, grinding wheel shoes, grinding wheel timber, paper mill wheel, grinding wheel, and other cloth.




2.
From the shape of the distinction between appearance of the style that is the product. The final shape of the finished abrasive wheel is different, the name is different.
Of course, the purpose is quite different. Preliminary points, mainly flat grinding wheel (circle, which both sides of the plane) and shaped sand
Round (irregular wheel) two categories. In actual use, flat grinding wheel in a dominant position, and its wide fan-shaped grinding wheel
More than made up for the shortcomings of flat wheel. Double-bevel wheel, single-bevel wheel, protruding wheel-sided, single-sided concave grinding wheel,
Sided concave grinding wheel, sheet wheel, cylindrical grinding wheel, cup grinding wheel, bowl-shaped grinding wheel, dish wheel, cylindrical grinding, round grinding cone
Head, spherical grinding head, Whetstone square, rectangular stone and so on.


Second, the hardness of the wheel selection and use



     


Wheel hardness
: The Wheel hardness selection and use of, for example, during normal use, the grinding wheel hardness refers to the wheel table
Sand surface during grinding off the degree of difficulty,
That is the extent of grinding wheel bond firmly bonded sand.
If the grinding wheel hardness
Is low, easy to fall off the sand, whereas the hardness of the wheel will be high, not falling. In order to meet the requirements of different grinding, you need to
There are various grades of hardness wheel wheel selection, in order to meet the needs of actual use, of abrasive hardness level according to
