A non-circular arc edge profile diamond cutter grinding device and method
By linking the swing shaft with the feed assembly, the distance between the swing shaft's rotation center line and the grinding wheel is changed, solving the problem that existing equipment cannot process non-circular arc cutting edges. This achieves efficient grinding of non-circular arc cutting edge diamond tools and simplifies the control difficulty.

AI Technical Summary
Technical Problem
Existing diamond tool grinding equipment cannot process non-circular arc cutting edge contours, and internationally, grinding machines with complex structures are difficult to control.
Method used
By changing the distance between the rotation center line of the swing shaft and the grinding wheel in real time during the swing process, the linkage between the swing shaft and the feed assembly is realized, forming a non-circular arc diamond tool cutting edge profile. The grinding motion is precisely controlled by a multi-axis linkage control system and an electrical control system.
Benefits of technology
It achieves efficient grinding of non-circular arc cutting edge diamond tools, simplifies control difficulty, and reduces equipment complexity.

Abstract
The application discloses a non-circular arc edge profile diamond cutter grinding device and method. The device comprises a feeding assembly installed on a bed; a swing shaft installed on the feeding assembly and linked with the feeding assembly; a cutter holder installed on a rotor of the swing shaft and used for installing a diamond cutter to be ground; the feeding assembly drives the diamond cutter to move along a feeding direction and applies a grinding pressure of the diamond cutter; the swing shaft drives the diamond cutter to make rotary motion; a reciprocating shaft installed on the bed and moving in a direction perpendicular to the feeding direction of the feeding assembly; a grinding spindle assembly installed on the reciprocating shaft and cooperating with the reciprocating shaft to drive a grinding wheel disc installed thereon to make high-speed rotary motion while performing reciprocating linear motion; and an electric control system used for controlling the feeding assembly, the swing shaft, the reciprocating shaft and the grinding spindle assembly, and realizing that an envelope line formed by grinding motion of the grinding wheel disc and the diamond cutter is a non-circular curve through linkage control of the swing shaft and the feeding assembly.
