Stone machinery is a widely used equipment in the industry, favored by customers. Saw blade is the primary part of stone processing in machinery, which is very important to the production effect of machinery. Today we will explain to you the abrasion damage of stone mechanical saw blade.
Due to the force effect and temperature, the saw blade after a period of use will often produce wear damage. The main forms of wear damage are as follows: abrasive wear, local crushing, large area crushing, falling off, mechanical abrasion of binder along the direction of sawing speed.
Abrasive wear: diamond particles and parts constantly friction, edge passivation into a plane, loss of cutting performance, increase friction. The heat of sawing will make the surface of diamond particles appear graphitized thin layer, greatly reduce the hardness, aggravate the wear: the surface of diamond particles under alternating thermal stress, but also under alternating cutting stress, there will be fatigue cracks and local crushing, showing a sharp new edge, is a more ideal wear form;
Large area crushing: the diamond particles bear impact load when cutting in and out, and the more prominent particles and grains are consumed prematurely; Shedding: Alternating cutting forces cause diamond particles to be constantly shaken in the binder and become loose. At the same time, the adhesive was softened by the wear and heat of sawing. This reduces the holding force of the binder, and when the cutting force on the particle is greater than the holding force, the diamond particle will fall off. Both kinds of wear are closely related to the load and temperature the diamond particles are subjected to. Both of them depend on Cheng cutting process and cooling lubrication conditions.
