Portal milling machine of Gantry type design WPA
ŠMT portal milling machine of Gantry type design with variable clamping area in the form of a clamping plates, optionally equipped with rotary or carousel table. The machine travel is 1m extended for the automatic pick up of milling heads at the end of the workplace. Sliding columns with a vertically movable cross rail are connected with a fixed beam, that reinforces the whole frame of the machine.
FULLY HYDROSTATIC AXIS
A headstock with an extensible ram is movable along the cross rail in the transverse direction. All axis are fully hydrostatic, guideways are covered by telescopic covers.
SPEED / HEAVY DESIGN
Portal milling machine can be equipped with two variants of headstocks
- SPEED design uses Direct Drive to achieve high working speeds
- HEAVY design offers a powerful torque design even with large diameter mills or boring operations
ACCESSORIES
The machine can be equiped with a set of milling heads to widen the machining possibilities of the machine. In the basic version, the milling heads are placed in pallets and equipped with automatic clamping on the ram face. Standard heads are facing and angular, optional NC controlled. Special milling heads can be added upon the request or for special technological operations.
The workstation also includes automatic tool changer - optional robotic tool changer with various magazine size. Tool cooling is external and through tool.
