Diamond Rabin is the result of an ideal combination of excellent rubber features of Daiwa Rabin and a diamond abrasive grain, which offers much greater performance and improves the processing as a new diamond tool that was not seen until now.
While “high-speed grinding” and “high-speed milling” have evolved remarkably as processing methods for improving the product quality and increasing the mass production performance, it is necessary to simultaneously increase the rigidity and precision (…. increase in cost) of tools and usage equipment, select tools and manage their status, and seek refinement in truing and dressing processes, as well as the drive programs. There are also inevitable problems such as heat generation, and other problems of processing damage, and occurrence of burrs due to difficulty in processing as a result of a minute size.
The grinding and polishing processes that make use of rubber elasticity have opened the path to an approach that is different from the high-speed technique, and have greatly reduced the problems and the cost factor accompanying high speed, which has made the superiority of Diamond Rabin stand out.
Rubber Elasticity is a feature of this tool
- There is no need to take measures against the large amount of heat generated during high-speed grinding and cutting.
- The residual stress and heat damage are reduced to a great extent, and as a result, micro-cracks can be prevented.
- Because Diamond Rabin exhibits excellent cutting quality even at medium and low speeds, there isn’t too much need for high rigidity and high precision of devices and tools used for high-speed rotation, which reduces the special additional cost for metal cutting machine tools.
- The excellent durability that Daiwa Rabin possesses is further improved thus increasing the life as compared to other tools.
- Large quantities of grinding fluid are not needed, and in some cases, semi-dry or dry processing is also possible.
- The grinding and cutting mechanism of a rubber stone is different from that of a grinding wheel and cutting tools, and ductile breaking may be expected to be a failure mode. An improvement in the surface finish is naturally expected, but at the same time, the concern over scratches from the polishing powder are also reduced. The cost involved can be reduced through the stability of quality and improvement in the yield.
- A dedicated dresser is not needed for truing or dressing. The dressing interval is also long, which reduces the cost of tool management.
- Diamond Rabin is also opening the path to automatic mirror polishing of aspherical areas as well as automation of mirror polishing of plastic molds, which has long been sought after, only by mounting a holder having a low-pressure and an eccentric mechanism on to the present unit.
