Annular grinding body and diamond grinding cutter head

Abstract

The invention provides an annular grinding body and a diamond grinding cutter head, and relates to the field of machining. The annular grinding body comprises a connecting part in a circular ring shape, and the far end of the connecting part is provided with an annular grinding end; the grinding end is divided into a first part, a second part and a third part which are connected with each other insequence from outside to inside, and the outer contour line of the cross section of the grinding end correspondingly further comprises a first contour line, a second contour line and a third contourline which are connected with each other in sequence, wherein the cross section penetrates through the central axis of the annular grinding body; the first contour line comprises a first straight linesection and a second arc line section, and the straight line is tangent to the arc line, and the first contour line is used for grinding the peripheral contour of a boss to be ground; the second contour line is a horizontal line, and is located at the foremost end in the grinding direction; the third part is a transition part from the second part to the fillet or chamfer of the inner wall of theconnecting part; and correspondingly, the third contour line is the outer contour line of the fillet or the chamfer.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an annular grinding body and a diamond grinding cutter head. Background technique [0002] With the development of the economy and the advancement of technology, the amount of grinding and polishing of various bosses continues to increase. In order to improve production efficiency, people continue to design grinding and polishing machines with larger grinding discs in order to grind more workpieces faster. However, increasing the diameter of the grinding disc will increase the processing difficulty of the grinding disc and increase the manufacturing cost of the grinding machine. At the same time, due to the large gap between the inner and outer radii of the large grinding disc, the linear speed has a large difference, and the grinding resistance is large, so the grinding quality of the workpiece is also affected to a certain extent, and it is not suitable for small bosses.

AI Technical Summary

Problems solved by technology

However, this kind of processing tool is only circular arc grinding, and there is a large gap between the peripheral contour of the grinding boss and the contour of the boss to be ground, and after a period of grinding, the front arc of the grinding end The top part is slowly ground, unable to play the role of grinding, and the service life is short
