Abstract

A press brake (1) includes: an upper table (7) disposed to face a lower table (5) in an up-down direction; a drive unit (24) including a drive shaft (41) to which power from a driving motor (25) is transmitted via multiple gear elements; a ball screw mechanism (55) that converts rotational motion of the drive shaft (41) to linear motion along the up-down direction; a brake mechanism (70) that applies a force that resists a force of downward movement of the upper table (7); and a control device (100) that performs lifting/lowering control of the upper table (7) for bending a workpiece. The control device (100) switches on/off the brake mechanism (70) in accordance with a control process in the lifting/lowering control of the upper table (7).
