[IMTS Preview] Rattunde Introducing New Integrated Sawing/Machining Center

ACS + CFMcurve Integrated Sawing and Machining Center

Rattunde is introducing the new ACS + CFMcurve Integrated Sawing and Machining Center, which uses sophisticated electronics, servo motors and custom-developed software to control the saw blade during the cutting process. A proprietary sawing algorithm yields the fastest saw cutting time, best surface finish, longest saw blade life available in the industry and overall reduced costs.

The CFMcurve machining center is a patented process that simultaneously machines each workpiece end using 12 independent servo-controlled axes. Machining options include: threading, boring, profile turning, grooving, radius edges and angled chamfering. Programming screens guide operators for quick setup on even the most complex part geometry. No special programming is required.

Precision parts are made in one continuous process with no operator intervention. Bundles of mill length stock, up to 16.5 meters long, are placed in an automatic loader, individually separated and fed to the sawing process. Cut parts are transferred to the CFMcurve machine for precise finishing. Utilizing advanced controls, linear ball screws and servo motors, all mechanical motion is seamlessly integrated into the machine design for full process control.

The technology incorporated delivers production rates and quality unmatched by the competition. For example a tubular component of 70 mm diameter, wall thickness of 5 mm, material type ST52-3 BK, with a length of 150 mm, machined with a 30 degree chamfer on the ID & OD with a faced end has a saw time of .96 seconds, a machined time of 1.86 seconds and can produce 1,820 parts per hour, inspected for length and automatically packaged. Cut length tolerance of +/- 0.15 mm at 1.67 CPK and a machined length tolerance of +/- 0.05 mm at 1.67 CPK are maintained.

The operator interface saves part files for instant recall when changing parts. Servo motors move all cutting and machining tools to their exact positions and implement saved parameters. No tooling change is required in the ACS Saw within a diameter range of 10 mm; there is a 5 mm diameter range in the CFMcurve. Tooling change for the complete system takes less than 20 minutes when necessary.

All critical sawing and machining parameters are monitored and controlled. Clamping forces and position, saw blade torque and vibration, and machining insert torque are continuously displayed and monitored. Operating limits are set and machine functions stop when they are not met. Saw blade and tooling insert wear is predictable and consistent. Key data for each part produced is stored in memory for statistical evaluation. All guesswork is removed from the operator.

The ACS + CFMcurve is available in two models with diameter ranges from 10 mm to 102 mm and 10m to 136 mm, with finished part lengths from 10 mm to 3500 mm. All material types can be processed.
