Diamond cutting discs has high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, as well as non-ferrous metal affinity small. It can be used for non-metallic hard and brittle materials, precision machining, such as graphite, high wear-resistant materials, composite materials, high toughness silicon aluminum alloy and other non-ferrous materials. Diamond tool type range, performance significantly different structure, preparation methods and applications of different types of diamond tools is quite different.
Sharpening diamond cutting discs Although there is no small achievement. But still mainly based on experience, so far there is to be explored. Usually the front angle of 0 °, after the angle of 5 ~ 6 °, its end, there are two, one arc and one straight ° line, which is sometimes referred to as wiper blade, according to the length of the material being processed to choose. Turning arc adjustment in the cutting process is relatively simple, and the relatively flat blade adjustment is very time consuming. If the application in high-precision surface machining, grinding arc very strict requirements, it will copy the merits of precision on the surface. Statistics show that diamond production is located in Osaka, Japan a few years ago will be able to reach R ± 0.05μm, Britain is even higher, reaching R ± 0.02μm.
Cutting process, the diamond has excellent thermal conductivity, heat dissipation, but be aware that cutting heat is not higher than 700 ℃, otherwise graphitization phenomenon occurs, the tool will soon wear. Because diamond at high temperatures and W, Ta, Ti, Zr, Fe, Ni, Co, Mn, Cr, Pt, etc. will react.
