C 250 machining centre

C 250 machining centre – the applications

Hermle Performance-Line

Within the model range, the C 250 can be seen as the entry-level model for 5-axis milling – and for the Hermle Performance-Line. Thanks to the wide-reaching swivelling range of the workpieces in the working area, the exploitation of the full traverse range and the large collision circle between the table sections, the C 250 has the largest working area in relation to the installation area. And it is constructed for everyday use: The application video shows the Hermle  C 250 U in the 5-axis version machining a Rockerbox in Toolox33 for vehicle technology.

Insights into the C 250

Maximum precision thanks to the Hermle swivelling rotary table concept. The machining table has a large worm drive. On the A axis you can directly access the gearwheel on the table housing. You can discover more details about the C 250 for 5-axis milling via the i-buttons in the 360 degree view. 

 

 

7 reasons for a C 250

They’re as reliable as a goalkeeper on his line, and as precise as a golfer’s putt – our machining centres prove their star qualities in all kinds of different industries whenever efficient and powerful milling and turning are needed. Get the best results, and make it to the top in all kinds of disciplines! To the video…

High-tech tool spindles with collision protection

Like the swivelling rotary tables, the tool spindles are also completely manufactured in-house at the Gosheim site. The slimline tool spindles are constructed in two parts and can be replaced easily and quickly during servicing. Thanks to low interfering edges and collision protection by compression sleeves, safety is given primary importance by maximum collision avoidance. Damage can be prevented in 50 % of collisions.

In manufacturing and operation

Hermle manufactures many components using lightweight construction and mineral casting technology. The high degree of own production, local suppliers and components with high efficiency factors also promote energy efficiency. Energy recuperation, high-quality servo drives and the legendary long service lives are all proof of the same high standards during actual operation.

The control unit provides for free contour programming and functions for fast 3D work as well as a trackball, USB and Ethernet interfaces. Options such as Dynamic Efficiency, Dynamic Precision or the Kinematic Opt. software also serve to widen the range of functions. Exact setup and control elements from Hermle simplify and improve operation.

Tool changer

The pick-up magazine of the C 250 is integrated into the machine bed, making for very good accessibility. There are 30 magazine pockets available, with a maximum tool weight of 8 kg and a maximum tool length of 300 mm. As an option, the capacity can be increased through the ZM 50 and ZM 88 additional magazines.

Flexible machine state monitoring

The HIMS control tool (‘Hermle Information Management System’) allows for flexible machine state monitoring even for the C 250 entry-level model, including a ‘Live Messenger’ amongst other features. The Hermle High-Performance Line models can also be automated to a considerably greater degree, including the addition of pallet changers, handling, rotary loading and robot systems and pneumatic arbour holders.

Everything well thought-through

Comprehensive fluid technology, optimized chip management, variety of cooling lubricant units: Even as an entry-level model, the C 250 has a number of highlights to offer, e.g. the right chip disposal equipment for removing all types of chip from the working area. The machining centre with 5-axis milling capability can be transported without being dismantled and set up without a foundation.
