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)

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.
