Claims

[Claims for Utility Model Registration] (1) A rotary main shaft 1 equipped with a chuck 2 that is attached and detached for processing a workpiece material M, and a processing shaft 3 that reciprocates in the axial direction in opposition to the chuck 2 on the main shaft side. In an automatic lathe that performs secondary processing by rotating the processing shaft 3, the processing shaft 3 has a concentric portion 38 centered on the main shaft and an eccentric portion 39 having an eccentric rotation center. An eccentric machining device characterized in that a shaft member 3' with a concentric portion 38 is attached to the inner diameter of a machining shaft spindle, and a cutting tool holder 9 is attached to the eccentric portion 39. (2) The tool holder 9 has a scale 37 on the outer circumference.
2. The eccentric machining device according to claim 1, wherein the cutting edge of the cutting tool can be freely adjusted in terms of distance and distance with respect to the center of the machining axis spindle. (3) The tool holder 9 is attached to the tool mounting part 4
3. The eccentric machining device according to claim 1, further comprising an adjusting screw 41 on the cutting tool mounting portion 40, and a screw 42 for fixing the cutting tool 10 engaged with the adjusting screw 41 so that the cutting edges thereof are aligned.
