Claims

[Scope of utility model registration request]

A pair of spindle devices 1 each having a chuck 3 at the tip of each spindle 2 for clamping both ends of a workpiece 4 to be machined, a drive shaft 6 interlocking between these spindle devices 1, and a drive shaft 6 and a gear to connect each spindle 2. In this case, each spindle device 1 is equipped with a brake-equipped spindle motor 7 that is driven through the row 5, and a backlash removal mechanism is provided to rotate each spindle 2 in the same direction when the workpiece 4 is clamped and the spindle motor 7 is in a braking state. A backlash removal device for a crankshaft mirror equipped with a cylinder 9.
