OPTIONS
Standard movable disc tool changer for 6 vertical + 3 horizontal tools with ISO 60 tool taper. Tool changes possible in any gantry position without the need of time-consuming travel. Other options available on request.
To maintain a high torque, we developed and produce the Angular heads in house. Our Angular heads can handle up to 5100Nm torque. Next to fix angular heads we also offer swiveling heads with a position angle of each 5° up to 0, 5°. In the range of milling heads, we also offer units with special shapes to have better access on difficult accessible work faces. The different heads are locked by a Hirth and clamped on the spindle by hydraulic pressure.
Movable head changer allows the head pick-up regardless the gantry position. It eliminates the need of time-consuming travel.
The modular design of the GMC range machine tools creates the possibility to add a second spindle from GMC 240. Both spindles can work simultaneously, machining 2 workpieces at the same time.
Depending on the specific characteristic of the work piece we have developed several clamping solutions, in order to reduce repositioning of the work piece and to have better accessibility. The clamps are designed to handle a high torque during operation.
Machine can be equipped optionally with movable crossrail to obtain optimal stroke of Z-axis during the machining.
Renishaw probe for measuring the work piece before and after machining.
Vertical milling machines can be equipped optionally with rotary tables.
