Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 8, an electrode for spark machining of a diamond saw blade capable of breaking chips comprises an electrode body 501 and a base 503, wherein the electrode body 501 is a copper electrode, the base 503 is an aluminum base, and the electrode 501 is an annular solid with a certain thickness. The end face of one side of the electrode body 501 is provided with a plurality of narrow grooves 502 which are uniformly distributed along the circumferential direction, the end face of the other side of the electrode body 501 is fixedly provided with a dovetail ring 507, the size of the end part ring of the dovetail ring 507 is phi 123mm, the included angle between the oblique line of the section of the dovetail ring 507 and the axis of the electrode body 501 is 15 degrees, the width of the narrow groove 502 is 0.6mm, and the depth is 6 mm.

A stress ring 505 is fixedly arranged on one side end face of the base body 503, an annular groove 506 is formed in the end face in the radial direction, a mounting hole 504 is formed in the middle of the upper portion of the base body 503, the mounting hole 504 is used for being connected with a machine tool shaft, the thickness of the aluminum base body 503 is 8mm, the outer diameter of the aluminum base body is phi 127mm, and the inner diameter of the mounting hole 504 is phi 32 mm; the outer edge of the stress ring 505 is 1mm wide, and the ring surface is 2.5mm wide; the annular groove 506 is 2mm deep and 10.5mm wide.
