PURPOSE: To efficiently machine a member with a plurality of parts to be machined by supporting turn-broaching tool units provided with cutting edges in the peripheral surface area, to a shank with axial distance. CONSTITUTION: The axial distance 10, 10' between the cutting edges 6, 26 and 6', 26' of units 5, 5a and 5', 5a' of tool rests 2, 2' can be changed taking account of the possibility of colliding with a workpiece. In the right half tool rest 2, the disc-like unit 5 is disposed being fixed in the axial distance to the tool rest 2 through a shank 4, and the tool rest 2 can drive the unit 5 in the form of turning around a turning axis 3. The second unit 5a is connected to the first unit 5 of the tool rest 2, and its axial distance can be adjusted by manually turning an adjusting screw 28. |
