Machining coolant/lubricant is used to operate a piston of a clamping-side coupler by feeding same via a coolant feed passage to a clamping pressure chamber through a first check valve and a clamping pressure fluid passage. The same coolant/lubricant is discharged from an unclamping pressure chamber through an unclamping pressure fluid passage and a second check valve. The resulting movement of the piston downwards brings a clamp member into contact with a workpiece to thereby clamp the workpiece on a table. Thus, a dedicated pressure source for clamping can be dispensed with.

A cutting tip has a cutting face and a flank face. A compression face for plastically deforming a workpiece is provided between the cutting face and the flank face. The cutting tip allows work-hardening to be easily performed by plastic deformation of the cut-finished surface during cutting, without adding a separate process step.
