Abstract:

Silicon carbide ceramics with its excellent physical and mechanical properties have become the preferred material of space large diameter mirror. But because of its higher hardness, diamond wheel would appear some wear form and wear rate in the mechanical processing process, wear form is an important factor to effect surface and subsurface quality, wear rate effects the surface shape accuracy, so the research on the laws of wear rate of grinding wheel has an important role in grinding. But, because of the particularity of wheel structure, wheel wear form and wear rate changes with time going, which limits the wheel wear research. By the grinding process experiment, the author found the relationship between diamond grinding block wear rate and wheel feeding, and got the laws of wear rate with time. With the laws of wear rate, we can predict the surface accuracy and guide the compensation of wheel feeding.
