stainless steel cutting discs Grinding damage

Grinding damage: As compared with the force and temperature effects should, after a period of use the blade tends to produce grinding damage. Mill damaged form are metal cutting discs‍ the following: abrasive wear, local crushing, crushing a large area, off, binders direction along the cutting speed mechanical abrasion. Abrasive wear: style pieces of diamond particles with constant friction, passivated edges into a flat, losing cutting, increasing friction. Heat causes the cutting of the diamond particles of the surface of a thin layer of graphite, the hardness greatly reduced, increased wear: the surface of the diamond particles exposed to alternating thermal stresses, and also to withstand the stress of alternating cutting, fatigue cracks occur locally broken, revealing a sharp new edge, is an ideal wear patterns; large area of ​​broken: to withstand shock loads when the diamond particles in the Leads, the more prominent grains and grain prematurely consumed; shedding: alternating the diamond cutting force binder particles are constantly shaking and loosening. Meanwhile, the wear and heat cutting the binding agent during the sawing itself soften the bonding agent. This gripping force of the bonding agent is decreased, the cutting force when the gripping force is greater than the particles, the diamond particles will fall off. No matter what kind flat cutting disc‍ of wear and tear are closely related to the diamond particles bear the load and temperature. Both of which depend on the sawing process and cooling lubrication conditions.
