Portal milling machine of table type design WP
ŠMT portal milling machine of table type design with clamping plate size according to customer‘s request. Table travel is 1m longer than plate length. Table load capacity according to the clamping plate size is 100 - 250 t. Fixed columns with a vertically movable cross rail are connected with a fixed cross beam that reinforces the whole frame of machine. The result is a very high rigidity and accuracy of the complete 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 equiped 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 equipped 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.
