结合剂的选择结合剂是把许多磨粒固结在一起,使之具有一定的形状、强度和良好磨削性能的材料。它除了应保证磨具在高速旋转时不破裂外,还应对磨粒有一定的把持能力,此外,结合剂还应有耐热和耐腐蚀能力,以便在干磨或在不同冷却液下湿磨时不会损坏。常用的结合剂列于表1 陶瓷结合剂由粘土、长石等陶瓷原料组成,生产过程中需经高温焙烧。它具有良好的耐热性及化学稳定性,不怕水、油
The choice of binder The binder is a material that binds many abrasive particles together to give them a certain shape, strength and good grinding performance. In addition to ensuring that the abrasive does not rupture during high speed rotation, it should also have some grip on the abrasive particles. In addition, the bond should have heat and corrosion resistance so that it can be wet or dry under different conditions Will not be damaged. Commonly used binders are listed in Table 1. The ceramic bond consists of clay, feldspar and other ceramic raw materials, which are calcined at high temperature in the production process. It has good heat resistance and chemical stability, not afraid of water, oil
