Abstract

A light emitting unit 109 of cutting insents testing unit 132 for testing cutting blade state of cutting insents and a photography unit 114 is arranged opposited, and fixed on cutting cover 104. As a result of the light emitting unit 109 and the photography unit 114 is arranged opposited, therefore, peripheral shape images which enable identify cutting blade 102a of cutting insents 102 definitely are obtained even if droplets of splashing cutting water existed. Otherwise, through fixing the light emitting unit 109 and the photography unit 114 on the cutting cover 104, thereby without need of using optical fiber and wiring. In this way, a cutting device with functions of photographing for cutting blade of cutting insents, testing imperfects and abrasion gets rid restriction of ligth for photography should use optical fiber wiring, enables hold the state of the cutting insents assuredly to photograph.

Description

technical field

[0001] The present invention relates to a cutting device having a cutting blade, and more particularly to a cutting device having a function of detecting the state of chipping and wear of the cutting blade. Background technique

[0002] Wafers formed with multiple devices such as LCs and LSIs are cut vertically and horizontally by cutting blades rotating at high speeds, and are divided into individual chips for use in various electronic devices.

[0003] The above-mentioned cutting insert is mounted on a high-speed rotating spindle and used, and a cutting edge portion is formed on the outer periphery thereof. The cutting edge portion is formed by fixing abrasive grains made of diamond or the like by means of electroforming, metal bonding, or resin bonding. Therefore, cutting causes the cutting edge portion to deteriorate over time, causing chipping and wear, and there are defects caused by cutting. The problem that the quality of each device deteriorates. ...
