Rattunde Corporation’s ACS + CFMcurve integrated sawing and machining center enables precision parts to be made in one continuous process with no operator intervention. The ACS saw uses a sawing algorithm with servomotor-controlled feed to continuously adjust critical parameters during each cut. The CFMcurve machining center simultaneously machines each workpiece end, using 12 independent servo-controlled axes. Machining options include threading, boring, profile turning, grooving, radius edges and angled chamfering. No special programming is required.
Bundles of mill-length stock, as long as 16.5 m (54') , are placed in an automatic loader, individually separated and fed to the sawing process. Cut parts are then transferred to the CFMcurve machine for precise finishing. With the machine’s CNC, linear ballscrews and servomotors, all mechanical motion is integrated into the machine design for full process control. Clamping forces and position, saw blade torque and vibration, plus machining insert torque are continuously displayed and monitored. Operating limits are set and machine functions stop when they are not met.
The operator interface saves files for instant recall when changing parts. Servomotors 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 machine. Tool change for the complete system takes less than 20 minutes.
The machine is available in three models with diameter ranges from 10 to 102 mm, 10 to 136 mm and 10 to 169 mm, with finished part length from 10 to 3,500 mm. Additional processes can be integrated, including part inspection stations, washing/drying, automatic packaging and automatic container changing.
