Claims

[Scope of utility model registration request]

In a wire-type cutting device that performs cutting by supplying machining fluid containing free abrasive grains to a wire pressing part while pressing and sliding a wire on a workpiece to be cut, there is a device that excites the workpiece with ultrasonic waves. A wire-type cutting device comprising: a load detector attached under a workpiece to be cut; and a power control device for controlling ultrasonic supply power so that the load is constant.
