New Combination Milling/Turning Machine



GF Machining Solutions unveiled at IMTS 2016 its new Mikron MILL P 800 U ST (Simultaneous Turning) machine that performs both milling and turning operations.

"The MILL P 800 U ST achieves perfect workpiece roundness, enhanced surface quality and high material removal rates to provide increased value," said a company spokesperson. Being able to fully machine components on a single machine also eliminates transfer-related part errors and the occurrence of stacked tolerances - further boosting finished part quality.

The MILL P 800 U ST is capable of 4-axis simultaneous turning, which is especially beneficial when cutting tools must be positioned at 90° angles to workpiece surfaces to avoid tool shape errors. "For milling, the machine incorporates a 20,000 RPM HSK T63 Step Tec HPC190 spindle - the industry's fastest for a milling and turning machine of this size," said the spokesperson.

The compact MILL P 800 U ST provides 31.5" (800 mm) of X-axis travel, 800 RPM C-axis rotation speed and a maximum table load of 1,763 lb. (800 kg). Water-cooled high-torque motors on the machine's A-axis and C-axis provide accuracy and stability, while a 0.3 second clamp time in any position further contributes to overall part processing speed.

At IMTS, GF Machining Solutions demonstrated the shear speed of the MILL P 800 U ST by cutting aluminum parts more than 50% faster than conventional processing.

GF Machining Solutions developed the MILL P 800 U ST with its gantry-type concept as a direct response to the needs of shops serving the automotive, aerospace, energy and general machining industries. The machine's small 137" x 118" footprint makes it easy to integrate into existing operations, replacing two machines in the process. With the new machine's gantry concept, workpieces on the 31.5" x 31.5" table are fully accessible without rotating the table. This eliminates errors related to table rotation and helps reduce the need for hand polishing part surfaces. The tool changer for the machine is also located so as to avoid having to move the table during tool changes as well.

GF Machining Solutions' Machine and Spindle Protection (MSP) system adds security to the machining process. It protects the machine and spindle in the event of crashes during set-up and/or machining. "As the only system to offer such protection in all directions/axes, MSP eliminates not only spindle damage, but also misaligned machine geometry as well as downtime and costs related to unexpected crashes," said the spokesperson.

The MILL P 800 U ST is automation ready and equipped with pallet changers for two, seven, nine or 12 pallets. It also easily integrates into existing automation systems, such as System 3R automation solutions.
