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 dept

Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] One way to solve the problem of wear and chip removal is to improve the structure and grinding form of the grinding wheel, so that the grinding fluid can enter the grinding area more easily and provide a larger space for chips. The invention is to set the abrasive layer at the axial front end of the grinding wheel There is an inclination angle, thereby changing the structure of the grinding wheel, making the grinding fluid more liquid into the grinding area, and at the same time, the grinding debris is also easier to discharge. The invention also changes the grinding method of the grinding wheel, see the attached image 3 , during grinding, make the ultra-high-speed point grinding wheel of the present invention parallel to the axis of the workpiece in the vertical direction, and the variable angle α ∈ (-0.5°, +0...

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...
