The C 650 machining centre supplements the top end of the Performance Line series

The Hermle company has developed the C 650 to extend its Performance Line series with a major step upwards, and now provides three machine models for economical 3 and 5 axis machining. The Performance Line is positioned below the High Performance Line consisting of models C 12, C 22, C 32, C 42, C 52 and C 62, and it very nearly matches their performance capabilities. The only differences are to be found in the accessory diversity, the price and of course the naming.

Like the C 250 and the C 400, the C 650 uses a modification of Hermle's tried-and-tested gantry-type design, with a mineral-cast machine bed that is manufactured in Hermle's own brand new mineral casting foundry in Zimmern ob Rottweil. The integrated, rigid clamping table can cope with workpieces up to a maximum of 3000 kg (1050 x 900 x 600 mm) in the 3-axis version, making it ideal for toolmaking, mould construction and machine construction. The swivelling rotary table of the 5-axis version can accommodate workpieces up to 1500 kg (Ø 900 x 600 mm), allowing for highly precise machining.

The traverse path in the stainless-steel-clad working area comprises 1050 x 900 x 600 mm with a vertical table clearance of 775 mm and a door aperture of 1050 mm. Ideal parameters for simple and safe crane charging.

The C 650 has an integrated tool magazine for 42 tools. Two additional magazines with 50 or 88 extra magazine pockets are available as options. The control panel of the C 650 is also designed to swivel easily to the magazine loading location, so the operator can enter the tool data directly into the tool table in the control system. The 200 mm high platform, adapted to the loading point, puts the operator in an optimal, ergonomic position to load and unload the tools.

The C 650 is equipped with the Heidenhain TNC 640 control system as standard, providing access to the full programming capacity of this proven system. The control panel has a large (19") colour TFT touchscreen such as will be standard on all Hermle machines from now on.

Optionally, the C 650 can be equipped with the ergonomically adjustable comfort control panel instead. The control system includes Hermle's own tried-and-tested setups that give the operator ideal support for managing all kinds of milling operations.

In addition, the various Hermle digital components such as HIMS (Hermle Information Monitoring Software) and HACS (Hermle Automation Control System) are available as options for the C 650.

For servicing, the Hermle Maintenance Diagnosis System is available for continuous monitoring of the machine's condition. It facilitates rapid machine diagnostics and status-oriented maintenance planning.
