In order to prevent an electrode tip 8 from being burred during dressing process, thereby attaining high quality and stability of the electrode tip, a tip dresser features a screw-threaded circumference 5 formed around the rotatable cutter holder 1 for securing a one- or two-piece formed cutter element 2, for permitting the holder 1 to be rotated in one direction A manually or by a suitable driver. Frusto-conical recesses are symmetrically formed in both sides of the holder 1 for receiving the electrode tips, allowing the cutter element 2 to be mounted so as to slightly extend by a predetermined amount beyond the conically recessed surface. Another feature is in the form of apertures 6 and 7 provided through the holder 1 for discharging the cutting chips: one aperture 6 formed on the forward front side of the rotating direction of one machining edge 2a for the bevel surface of electrode tip 8, and another one 7 on the forward front side of rotating direction of another machining edge 2b for the end surface machining. The aperture 6 is formed along the edge 2a, and aperture 7 is formed so as to reach at least the boundary between the bottom and the conical side surface of each of the frusto-conical recesses.

Tip dresser

An improved tip dressing process is provided wherein the pressure between the electrode tip of a resistance welder and the cutter of a tip dresser is varied during the tip dressing process. A pressure controller is also provided for controlling the pressure between the electrode tip and cutter during the tip dressing process. The pressure controller may be applied to independently control the tip dressing process of several resistance welders simultaneously.
