Novel superspeed point grinding wheel and grinding method thereof

Abstract

The invention discloses a novel superspeed point grinding wheel and a grinding method thereof, wherein for the superspeed point grinding wheel, an inclination angle theta is arranged on a grinding wheel rough-grinding area so as to lead the contact form of the grinding wheel and a workpiece to have a change and be capable of saving the overall cost of the grinding wheel, and as grinding liquid is easier to enter a grinding plane, the abrasion of the grinding wheel is reduced, and the repair cost and difficulty can be decreased; the existence of the inclination angle theta more easily discharges cuttings out of the grinding area, the axis of the grinding wheel and the axis of the workpiece are in parallel in vertical direction when the grinding wheel is ground, the variable angle alpha belonging to (minus 0.5 degree to plus 0.5 degree) of the axis of the grinding wheel and the axis of the workpiece in horizontal direction can lead the cuttings when the grinding wheel is ground to have certain angles, thus reducing the grinding cuttings accumulation phenomenon.

Description

technical field [0001] The invention relates to the field of grinding, in particular to a novel ultra-high-speed point grinding wheel and a grinding method thereof. Background technique [0002] Quick-point grinding (Quick-point Grinding) is an advanced high-speed grinding technology developed and patented by Mr. Erwin Junker of Junker Company in Germany in 1984. It integrates three advanced technologies of high-speed grinding, CBN superabrasives and CNC flexible processing, and has excellent processing performance. develop. It not only has the versatility and high flexibility of CNC turning, but also has higher processing efficiency and precision. The grinding wheel has a long service life and stable quality. It is an excellent combination of the new generation of CNC turning and high-speed grinding, and has become the first One of the main technical forms. At present, Germany is in a leading position in the research and development of this technology. At present, it ha...

Problems solved by technology

Correspondingly, this process method has a large grinding depth, and the force state at the junction of one end of the grinding wheel and the end is the worst during grinding, and the grinding load is also concentrated on the circumference of the grinding wheel near the section, and the design level of the grinding wheel will directly Affect the surface quality of the workpiece after grinding

[0004] The process of ultra-high-speed point grinding is characterized by large depth of cut and high material removal rate. The removal of chips in the grinding process is a key issue. However, the grinding chips generated during the use of existing grinding wheels are not easy to discharge, and when grinding When the load is large, it is easy to cause the wear of the grinding wheel. In order to obtain good grinding quality, the worn grinding wheel needs to be trimmed, which further increases the loss of the grinding wheel and increases the processing cost.
