Claims (1)

[Claims for Utility Model Registration] 1. A plurality of cutting blade forming parts each having a front surface inclined so that the front surface in the rotational direction of the cutting blade forming part and the outer peripheral surface form an obtuse angle are provided at intervals on the outer periphery of a circular substrate, In a diamond abrasive electrodeposited cutter in which a cutting edge is formed by bonding diamond abrasive grains to the surface of a blade forming part by an electroplating method, at least one carbide chip is attached to the rear surface in the rotational direction of the cutting blade forming part. Diamond abrasive electrodeposited cutter. 2. The diamond abrasive electrodeposited cutter according to claim 1, wherein the carbide tip has a height and width smaller than the cutting edge on which the diamond abrasive grains are electrodeposited. 3. Claim 1, wherein the carbide tip is attached at a ratio of one to at least two of the cutting edges.
Diamond abrasive electrodeposited cutter as described. 4. Claims 1 and 2, wherein the cutting edge forming portion has a thinner wall thickness near the connection portion between the front surface in the rotational direction and the outer circumferential surface.
Or the diamond abrasive electrodeposition cutter described in 3. 5. The electrodeposition of diamond abrasive grains according to claim 1, 2, 3 or 4, wherein the wall thickness in the vicinity of the connection between the front surface in the rotational direction and the outer circumferential surface is thinned by alternately scraping off both sides of the cutting edge forming part. Cutter. 6. In the case of reducing the wall thickness near the connecting portion between the front surface in the rotational direction and the outer circumferential surface, a thinned portion is provided by continuously scraping at least from the same surface side of the plurality of cutting edge forming portions. Or the diamond abrasive electrodeposition cutter described in 5.
