Abrasive industry will also play an important role, especially resin CBN grinding wheels that have greater contribution to the automotive industry.
According to the latest news, auto industry will get high speed development as a pillar industry for national economy for quite a long time in the future. Abrasive industry will also play an important role, especially resin CBN grinding wheels that have greater contribution to the automotive industry.
In the process of using resin CBN grinding wheel, abrasive grains will fall off from the abrasive products partially or completely if abrasive grains fracture or the bond fractures. But they keep appearing the new cutting edge on the surface of abrasive products, or constantly expose new sharp abrasive grains, which can help abrasive products keep cutting performance in a certain time. The sharpness is prominent characteristic compared with general cutting tools.
Particle size refers to the size of the abrasive grains. Particle size can be divided into two categories: abrasive grain and micro powder. The classification is decided by the screening method, and grain sizes are shown by mesh in one inch. For example, abrasive grain 60# can pass the screen that has 60 mesh in each inch. For abrasive particle size less than 40μm, they are called micro powder. After microscopic measurement grading, W and the numbers represent the granularity size, and the W represents the actual size of the powder. For example, W20 means the actual size of powder is 20μm.
At present, aimed at present situation of automobile industry in our country, taking mature experience of developed country for reference, we should mainly develop: machining piston ring CBN abrasive disk; High precision high wear-resistant resin CBN grinding wheel (including resin ceramic bond); All kinds of cast iron parts processing with PCBN cutting tools, honing tools; All kinds of hydraulic parts small hole grinding head for processing; Car Windows, car rearview mirror and a variety of diamond grinding wheel, drill; Plastic, rubber, and other non-metallic materials diamond grinding wheel; Aluminum alloy parts processing with CPD cutting tool; Diamond dressing roller and so on.
