The work envelope of the C 650 is defined by X-, Y- and Z-axis travels of 1,050, 900 and 600 mm. Every Hermle machine shares the same fundamental attributes, including a modified gantry design, mineral cast bed and an integrated, trunnion-mounted rotary table for the fourth and fifth CNC axes, if specified.
In the 3-axis version, the table can accept workpieces weighing 3,000 kg, making it suitable for tool and mould making. Alternatively, precision machining of components up to 900 mm in diameter by 600 mm tall, and weighing 1,500 kg, is possible on the ±115° swivelling rotary table of the 5-axis version. Minimal idle times result from 6 m/s2 acceleration to 35 m/min rapid traverse in all axes.
Spindle options are 15,000 or 18,000 rpm, and both are equipped with Hermle's patented collision protection system. In the event of impact in the Z-axis direction, energy is absorbed by six displacement sleeves to minimise and often prevent spindle damage.
The integral magazine for 42 tools can be expanded by 50 or 88 additional pockets. Further options include enhanced cooling and chip management, extractors, as well as tool breakage monitoring and measurement, touch probes and precision packages. Control is via Heidenhain’s TNC 640.
