Abstract
A cooling jacket includes a coolant supply member that circulates a coolant, and a coolant injection member to which the coolant is supplied from the coolant supply member, the coolant injection member provided with multiple injection holes through which the coolant is injected. The coolant injection surface of the coolant injection member opposing the workpiece has an upper region, a central region, and a lower region arranged along a vertical direction. An area of each injection hole provided in the central region is larger than an area of each injection hole provided in the upper region and an area of each injection hole provided in the lower region. The coolant injection member moves relative to a workpiece in a horizontal direction. A densest direction in which the multiple injection holes are arranged at the shortest intervals is inclined with respect to both the horizontal direction and the vertical direction.
