Embodiment Construction

[0037] Next, a tool holder 10A according to a first embodiment of the present invention will be described. The tool holder 10A is composed of a holder main body 11 and a sub-holder 20 held inside it. figure 1 It is a plan view, a front view, a bottom view, and a cross-sectional view showing in detail the holder main body 11 of the tool holder 10A used in the embodiment of the present invention. Such as figure 1 As shown, the retainer main body 11 has a square cylindrical structure, and has a through-hole 12 having a circular cross-section along its central axis in the central portion. A truncated conical tapered portion 13 is formed on the upper portion of the cage main body 11, and both the inner diameter and the outer diameter gradually become smaller. The tip of the tapered portion 13 is the opening of the through hole 12 . The tip angle α2 of the inner diameter of the truncated cone of the tapered portion 13 is, for example, 90°, and the tip angle α1 of the outer diamete...

Abstract

Technical Problem: Reliably hold diamond tools of all shapes. Solution: Fix the sub retainer (20) to the retainer body (11), the retainer body (11) having a circular through hole inside and a tapered portion (13) on the upper part. A notch (23) is formed in the sub-holder (20) from the top, the diamond tool (30) is held in the notch (23), and the sub-holder (20) is fixed to the holder body with a set screw (18). (11) inside. In this way, the notch (23) is pressed and clamped by the inner wall of the tapered portion (13), and the diamond tool (30) can be held.

Description

technical field [0001] The present invention relates to a tool holder for holding a diamond tool for scribing brittle material substrates such as glass substrates and silicon wafers at its tip. Background technique [0002] Conventionally, for scribing a glass substrate or a silicon wafer, a tool using a diamond tip made of single crystal diamond has been used. A tool is held by a tool holder by welding or the like in a vacuum furnace as disclosed in Patent Document 1 and the like. In addition, Patent Document 2 discloses a structure in which a diamond scriber is held on a holder of a shank, a pressing part having a pressing claw is attached to the upper part of the handle, and held by the pressing claw.
