All-in-One Work-Handling System Moves Workpieces Weighing 450 kg

Hermle’s HS Flex work-handling system is designed as one complete unit to fit the C 250 and C 400 machining centers of the company’s Performance line, and the C 12, C 22, C 32 and C 42 models of the High Performance line. Only the workpiece storage modules are installed separately.

The flat mineral casting bed, on which the three axes of the handling unit are operated, promotes ergonomic and convenient access for the operator. The unit also has two double-leaf doors, which prevent access by the operator during a pallet change procedure and provide access to the working view position and working area while preventing access to the handling unit during machining.

The rotary, lifting and linear axes of the handling unit enable movement of workpieces weighing as much as 450 kg (including the pallet) between the setup station, storage modules and the machining center’s working area. The unit can handle pallets as large as 500 × 400 mm. To minimize operator errors, the maximum workpiece height is queried at the setup station, preventing operators from feeding in workpieces with dimensions beyond what is specified.

One storage module comes standard with the HS Flex unit, and an optional second storage module is available. The modules are structured as racks, offering customization in the pallet/workpiece arrangement. Up to four rack shelves can be ordered with as many 20 pallet storage spaces per module. The storage arrangement can be defined quickly and easily using a specially developed storage generator, which tests both the permitted weights and dimensions.

The HS flex is controlled and managed by the Hermle Automation Control System (HACS). HACS allows for smart order management, which aids the operator in daily business via software with a touch panel.
