GF Machining Solutions has introduced the Mikron Mill P 800 U ST machining centre, which integrates milling and turning in a single machine. This compact model provides 800 mm of X-axis travel, an 800 rpm C-axis rotation speed and a maximum table load of 800 kg.
The Mill P 800 U ST offers a gantry-type concept in direct response to the needs of component manufacturers serving the automotive, aerospace, energy and general machining industries. A small footprint makes it easy to integrate the machine into facilities where space is at a premium.
Being able to fully produce prismatic and turned components on a single machine also eliminates transfer-related part run out and accuracy errors, and helps alleviate production bottlenecks. The five-axis simultaneous Mill P 800 U ST is also capable of four-axis simultaneous turning, a capability often required by customers that need to have the cutting tool positioned at a 90° angle to the workpiece surface to avoid tool shape errors.
Mill P 800 U ST machines incorporate a 20,000 rpm HSK A63 spindle that GFMS says is the industry’s fastest for a milling and turning machine of this size. Water-cooled torque motors for the A and C axes ensure accuracy and stability, while speed has received a boost through the axes’ 0.3-second clamp time in any position.
With the new machine’s gantry concept, the workpiece on the 500 x 730 mm table is fully accessible without rotating the table. This design eliminates errors related to table rotation and avoids the need for hand polishing. The tool changer for the machine is also located so as to avoid moving the table during tool changes.
