- Extra-reinforced chip basket and chip sieve with magnetic insert
- Stainless steel control panel with durable markings
- 4 central lubrication points for the trapezoidal spindle drive with manual grease gun
- Electrical preparation for an external control element (16-pin connector)
- Preparation for automatic clamping jaw opening during profile broaching via roller lever
- Machine documentation with "CE" confirmation declaration

Optional additional options:
- Automatic clamping jaw opener for easier tool removal during profile broaching
- Open 3-sided splash guard cabin (w x d x h) 700 x 350 x 600 mm
- External electrical control unit for broaching and return stroke, as well as emergency stop operation

Note:
The machine has been completely overhauled. During the overhaul, the machine base, machine body, and machine table were completely refurbished. All other components have been replaced. The drive system has been modified. The machine has been updated to the state of the art and complies with current CE regulations (as of 2024).

General
The dual-spindle drive ensures a smooth and central pull point and a constant broaching speed. The machine is primarily designed for the production of keyways up to 20 mm. (From 16 mm keyways, only with stepped tool shanks).
Due to its design, the machine is quick and easy to set up for broaching with flat broaching tools for keyways.
