Sawing technology + CFMcurve Chamfering with Curve Machining
Precision system for complex processing
of tubes and solid material.
Cutting and end-machining
The ACS+CFMcurve production system automatically saws master lengths/fixed lengths into workpieces of any length and transfers these automatically to a subsequent machining process, such as end machining of both ends. The extensive range of machining options for this system includes turning, chamfering, thread cutting, axial machining, radial machining, milling, drilling (center drilling, radial drilling), profile turning, groove cutting, radius chamfering and angled chamfering. All this turns the production of precision shafts into child’s play!
RATTUNDE quality, durability and optimal performance ensures process reliability in your production!
From cutting tubes to contouring edges
Whether you're manufacturing camshafts, bushings, airbag cartridges, shock absorbers or precision shafts...
With RATTUNDE systems you’ll produce sophisticated products of outstanding quality!
Innovative, user-friendly and powerful

- Clamping force continuously adjustable
- Defined outward transfer of workpieces according to individual parameters, when e.g.
- workpiece lengths are incorrect
- clamping errors occur
- the saw torque is outside the target range
- a cut is incomplete
- Compliant with CE requirements as well as applicable directives and guidelines of the European Union and North America
- Integrated system for the most demanding end machining
- End machining with 2 CFMcurve chamfering heads and 3 cutting tool holders with CNC supports (RATTUNDE patent)
- For complex machining tasks (e.g. inside groove/outside groove, facing with inside or outside deburring, inside/outside thread, outside chamfer with radius/inside chamfer with radius, center drilling, etc.)
- Optional – Extraction of machining chips directly at the source (chamfer)
- Optimal workpiece positioning and centric clamping of the workpieces to the end-machining heads (horizontally and vertically 0.001 to 0.1 mm)
- Central monitoring and operation of the cutting tools and machining parameters
- Workpiece counter
- Cutting area
- Torque
- Tool wear
- Central monitoring of workpiece clamping on the CFMcurve clamp
- Centralized entry and administration of limit values
- Clamping force continuously adjustable
- Length measurement for each workpiece after chamfering
- Automatic workpiece length correction
- Automatic and defined outward workpiece transfer if:
- the previously defined tolerances are exceeded
- clamping errors occur
- the chamfering torque is exceeded or not reached
- Service life extension of the cutting tools via automatic shifting of the tool edge (no manual adjustment of the cutting tools required)
- Changing the machining length for the inside and outside chamfers during the machining process
- Select and define precision machining
- Definition of the transitions between chamfers, facing and outer wall with radius or facet
- Definition of various machining tasks and machining lengths for both workpiece sides and simultaneous machining (e.g. contour and thread)
- Thread cutting with chip-breaking stroke (inside and outside thread)
- Set-up of the position and depth of inside and outside grooves
- Changing the contour machining direction
- Create contours with different parameters for each operation
- Freely select chamfer angles or multiple chamfers for contours
- Free definition of the machining process (e.g. creation of a contour before or after the thread)
- Separate assignment of different thread pitches for both workpiece sides
- Enter the angularity (inside thread and outside thread) for both workpiece sides
- Cut the inside and outside thread with different infeed options
- Chip length reduction via input parameters
Optimal performance right from the start!
