More specifically, the present invention relates to a cutting tool of a tip dresser capable of preventing the cutting edge from being damaged by reducing the cutting amount of the cutting blade when the welding tip is pressed against the cutting tool with a large pressure.

のできるドレッシング方法を提案した。Since the cutting tool cuts both the side surface and the end surface of the welding tip, a blade having integrally formed cutting edges on the side surface and the end surface is used. The pressure applied during dressing of the welding tip was the same as during welding. However, with this method, the cutting edge bites into the welding tip, and the cutting edge is often damaged due to the impact force at the time of pressing, which hinders the cutting of the welding tip. Therefore, the applicant of the present application, in Japanese Patent Application No. 4-204701, first performs pre-pressurization at a low pressurizing pressure, then increases the pressurizing pressure to perform roughing, and pressurizing pressure to pre-pressurizing or lower. We proposed a dressing method that can reduce the cost due to breakage of the cutting tool and the labor of replacement by lowering and finishing, and improving work efficiency.

が、加圧圧力の設定可能範囲が狭いために、適切な加圧
圧力の設定が困難であるという問題があった。However, even with this method, if the pressure applied during rough machining is too large, the cutting amount of the cutting edge becomes excessive, cutting resistance increases, and the cutting edge is likely to be damaged. , There is a problem that an excessive load acts on the rotation of the cutting tool of the tip dresser to prevent the cutting tool from rotating normally, and if the pressure applied is too small, the tip of the welding tip swings and normal cutting cannot be performed. The inconvenience occurs. Therefore, it is necessary to properly select the pressurizing pressure at the time of roughing according to the material and diameter of the welding tip, but it is difficult to set the appropriate pressurizing pressure because the settable range of the pressurizing pressure is narrow. There was a problem.

An object of the present invention is to obtain a cutting tool for a tip dresser that effectively prevents the occurrence of movement and is less likely to cause inconvenience such as chipping of a cutting edge.

The pressing method is as follows. First, at the welding tip setting time T1, the set pressure is lowered and pre-pressurization (a) is performed, and the set pressure is set from the time when the welding tip and the cutting edge 4 '(see FIG. 2) of the cutting tool come into contact with each other. To the roughing pressure (b), and the cutting time T
Maintain this (b) pressure until 2 has passed. After the lapse of the cutting time T2, the set pressure is reduced to the finishing processing pressure (C), and this (C) pressure is maintained until the finishing processing time T3 elapses.

As shown in the figure, when the conventional cutting tool is used, the settable range B of the pressurizing pressure at the time of roughing is about 100 kgf
Although it was up to 150 kg · f, the settable range A of the pressurizing pressure when using the cutting tool of the present invention was about 100 K.
It was expanded from gf to 240 Kgf. Therefore, it suffices to appropriately select the pressurizing pressure within the range in which the tip of the welding tip does not swing during the roughing process, and the appropriate pressurizing pressure can be set extremely easily and quickly.
