Equipment:
- Gear motor drive with 2 working speeds
- Reinforced draw bridge made from tool steel for higher tensile forces
- Safety door with door interlock, safety interrogation and safety monitoring
- Easily removable chip chute with tool extraction protection and parking facility
- Externally adjustable tool length setting system (reproducible across machines)
- Protective covers for stroke adjustment and electrical switching units
- Oil-tight tray on the control cabinet
- Electrical sensing of clamping jaws (tool extraction monitoring prevents unintentional retraction of the draw bridge – extra safety for operator and tool)
- Integrated coolant system with electrically switched solenoid valve and drain tap
- Coolant swivel system with automatic coolant switching via the swivel system
- Extra reinforced chip basket and chip screen with magnetic insert
- Stainless steel control panel with permanent labelling
- 4 central lubrication points for trapezoidal spindle drive with manual grease gun
- Electrical preparation for external control element (16-pin connector)
- Provision for automatic clamping jaw opening during profile broaching with roller lever
- Machine documentation with “CE” declaration of conformity

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

Note:
The machine is 100% compatible with Rausch broaching machines of the same performance class in the RS 3, RS 4, and RS 6 series available on the market. All fixtures, tools or arbors can be used 100% interchangeably.

General information:
The double spindle drive ensures a smooth and centered pulling force as well as a constant broaching speed. The machine is primarily designed for the production of keyways up to 20mm. (From 16mm keyway tool width only with stepped tool shanks)

The design of the machine allows for fast and easy setup for broaching with flat broaching tools for keyways.

Thanks to the universally constructed drawbridge and machine table, broaching with both profile and flat broaching tools is possible. Profile broaching can be performed without the use of additional pull heads, by using simple centering bushings.
Suitable broaching tools and arbors for the machine are available on request.
