The traditional way of grinding in the laboratory testing stage and some shortcomings of the grinding
Hard material sphere is the bearing, roundness, gyro and other precision measuring instruments is an important element in precision instruments and equipment has a
cup wheels position. However, due to the traditional grinding method of the production process by human factors, consistency and stability is poor, high processing costs, it is difficult to obtain the degree of hard materials golf balls to make the application of rigid material sphere is still limited. The traditional way of surface grinding and some grinding at the laboratory testing stage approach,
this paper proposes a set
of high-precision machining technology programs, namely solid abrasives - double rotation grinding way around the basic theory of this processing method, the key technology and equipment research and
Resin Bond conduct research for hard materials, precision ball into a ball mechanism, from the grinding process ball billet motion analysis,
the ball billet
surface grinding trajectory distribution, spherical error correction, ceramic ball material removal and other issues, combining fixed abrasive grinding technology, dual rotation of the grinding technology, the grinding process factor analysis, and several other aspects of the new precision ball hard material grinding method is used.
Diamond deposition technique to repair diamond tools prepared
The use of diamond deposition technology for diamond tools prepared to repair process,
not only can the newly
formed diamond
deposition on tool in the gap,
but also can make the
tool diamond particles to be regenerated opportunity to further develop improved surface,
cutter wheels the particle performance. MPCVD method has been successfully used after the plating of the diamond particles and the matrix metal between the gap repaired. In the observation of diamond particles with an average size of centerless grinding morphology of electroplated diamond tools, you
will find there are
angular and irregular surface defects in the diamond particles and the matrix metal between the concave and voids. Put the tool into the deposition MPCVD system, the average particle size of the diamond growth of diamond particles Resin Bond by SEM and the matrix metal has been recovered and the gap between the surface of the diamond particles showing the rules and full. Using this method to repair electroplated diamond tools, electroplated diamond tools than unrepaired higher cutting forces, wear and particle adhesion. In MPCVD process temperatures, between diamond and matrix will form carbon - metal bond, the diamond particles and the binding strength between the metal matrix.
