Pneumatic unloading system for Swiss DT26 machines

For long and fragile workpieces with delicate features such as threads, the standard long-part system on the Swiss DT and Swiss GT sliding head machines may not provide the careful handling of the part required by the end-user. For such types of workpieces with a diameter up to 24mm and a maximum length of 260mm, Tornos has now designed a solution that enables parts to be removed with particular care.

The new solution has been specifically designed on demand by Tornos’ development team for specialist tasks. This internal team of experts is always on-hand to develop special solutions to meet the demands of customers, regardless of the machine model. Such solutions are not restricted to sliding head lathes and bar turning applications but also developed for milling, automation and robot automated purposes.

Designed to unload workpieces without damage to the machined features and to preserve the excellent surface finishes achieved by the capabilities of the Swiss DT26 machine, this system can solve various problems related to fragile workpieces. Mounted on the tooling block for back machining it does not impair the possibility of using the T510 and T520 tools.

Ejection is achieved pneumatically by using clamping jaws adapted to the respective workpiece type and material to ensure there is no harm to the workpiece. The jaws can be manufactured using a 3D printer and can be customised to the workpiece form to be machined, giving endless possibilities.

The system is equipped with sensors used to monitor machine movements, provide optimum protection of the device and avoid interference with the counter-spindle of the machine. With the addition of this system, a machine can be kept up to date and in conformance with customer component requirements, whilst employing only minor modifications. Existing machines can be easily retrofitted with this function and the appropriate software functions loaded into the machine control.

The system is used in conjunction with a machine’s standard parts conveyor belt but can be supplemented by the addition of a robot for workpiece palletising or even workpiece cleaning and measuring functions.

Based on the measured data, it is also possible to update offset values on the machine automatically.
