Diamond Tool application recommendations

Diamond blade has changed the traditional machining process to solve the production process before a lot of the problem is difficult to solve. Now widely used in

machinery, metallurgy, mining, high-speed trains, cars, tractors, bearings, pumps, transportation, energy, precision instrument

Control, aerospace and other industries Bing achieved remarkable economic benefits. For example, Changchun FAW Group Corporation with PCD tool fine boring high silicon

aluminum alloy piston pin hole (VC = 160m/min, f = 0.08 ~ 0.10mm / r, ap = 0.05mm), tool life up to 42,500 pieces,

Is 90 times the original carbide tools, surface roughness Ra increased from 0.8 ~ 0.4μm down to 0.4 ~ 0.2μm, alignment tool can reduce class size and other auxiliary

time 30min, allocated to each of the cost of the tool on the workpiece also fell by more than 85% of carbide cutting tools .
Currently the world's annual consumption of diamond material was 8% to 10% growth rate. Synthetic single crystal diamond material is the coarse particles, high

strength, multi-direction, the maximum weight of particles up to 11.14 kt. PCD is to a large diameter, fine-grained, high impact, high fever

Stability direction. PCD maximum diameter of up to 74mm. China since 1963 has been a successful development of synthetic diamond has gone through nearly 50 years of

development. At present, China's annual production of synthetic diamond ranks first in the world, Bing can produce a variety of high-grade and high-strength

Degree of synthetic diamond for the promotion and use of diamond cutting tools created favorable conditions.
A machine using a diamond cutting tool must have a high rigidity, high power and high speed. In addition, better precision machine tools, jigs and clamping the

workpiece clamping device, requiring reliability, so as not to cause vibrations generated when machining tool breakage. Must be noted that mesh

Many machine tool equipment before production can not meet the processing requirements of diamond tools, so their potential can not be fully realized in the future as

CNC machine tools (NC) machines and machining centers (MC) device applications, such as efficient increase (China Investment 221 billion yuan

Major national science and technology projects, "high gear CNC machine tools and basic manufacturing", which started in early 2009), will further promote the use of

diamond tools.
Diamond grinding and machining tool regrinding blunt the key issue is to use, it is a highly confidential nature, great technical difficulty. Abroad, the majority of

enterprises using diamond tools do not own knife, but will return with a blunt diamond tools factory resharpening.
China's current development of diamond tools, one should pay attention to introducing and absorbing foreign technology, ways to improve the quality of the blade,

reducing the cost of the blade; the other hand, further developed the finer grain size of the material to increase its density, reducing blade mouth jagged edges

, So that it can grind even more sharp. While sharpening diamond tool to solve the efficiency and quality issues.
It is noteworthy that, with the raw synthetic polycrystalline diamond graphite body, the current diamond is C12. Isotope C13 and C60 are more rigid. It can be expected

that in the 21st century the coming years, there will be greater progress in diamond tools and get more
