Used Key-Way Punching Machines

Keyway punching machines are special machine tools used to punch keyways in workpieces. Keyways are elongated grooves cut in workpieces to ensure accurate positioning of shafts, bearings or other components. The keyway punching machines use special punching tools to punch the keyways into the workpiece. The punching tools consist of a punch and a die, usually made of carbide to ensure long life. The workpiece is clamped into the machine and the punch is pressed into the die by a mechanism to punch the keyway. Keyway punching machines come in a variety of sizes and capacities, depending on the requirements of the application. Most machines are semi-automatic or fully automatic and have a feeding system that automatically feeds the workpieces into the machine. Keyway punching machines are used in a variety of industries, including automotive, aerospace, machinery and many others. They are particularly useful in the manufacture of gears, bearings and other components that require precise positioning.
