Note:
The machine is completely overhauled. During the overhaul, the machine base, machine body, and machine table were fully refurbished. All other components have been renewed. The drive system has been modified. The machine has been brought up to current technical standards and complies with the latest “CE” regulations (as of 2024).

General
The double-spindle drive provides smooth operation, a central pulling force, and a constant broaching speed. The machine is mainly designed for the production of keyways up to 20mm (for broaching tools from 16mm only with stepped tool shanks). The machine’s design enables quick and easy setup for broaching with flat broaching tools for keyway production.
