GF Machining Solutions Introduces Mikron MILL P 800 U ST for Milling and Turning

LINCOLNSHIRE, Ill., – GF Machining Solutions has introduced the Mikron MILL P 800 U ST (Simultaneous Turning) to expand its technology portfolio to include milling and turning in a single machine. Highly efficient, the compact machine provides 31.5" (800 mm) of X-axis travel, an 800-rpm C-axis rotation speed and a maximum table load of 1,763 lbs (800 kg).

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.

The combination of milling and turning technology in a single machine helps manufacturers achieve optimal productivity, accuracy and cost effectiveness. The MILL P 800 U ST achieves perfect workpiece roundness, impeccable surface quality and a high material removal rate to achieve incredible value. Being able to fully machine components on a single machine also eliminates transfer-related part run out and errors and increases finished part quality.

The MILL P 800 U ST is capable of four-axis simultaneous turning, a capability often required by customers who need to have the cutting tool positioned at a 90-degree angle to the workpiece surface to avoid tool shape errors. The machine incorporates a 20,000-rpm HSK T63 spindle that is the industry’s fastest for a milling and turning machine of this size. Additionally, water-cooled torque motors on the A-axis and C-axis ensure accuracy and stability, while speed is enhanced through the axes’ 0.3-second clamp time in any position.

With the new machine’s gantry concept, the workpiece on the 31.5" x 31.5" table is fully accessible without rotating the table. This 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.

GF Machining Solutions’ Machine and Spindle Protection (MSP) adds security to the machining process by protecting the machine and spindle against crashing during setup and machining. As the only system on the market to offer protection in all directions, MSP eliminates the spindle damage, misaligned machine geometry, downtime and costs related to unexpected spindle crashes.

The MILL P 800 U ST is automation ready and equipped with pallet changers for 2, 7, 9 or 12 pallets. It can also be easily integrated into existing automation systems, including System 3R automation solutions.
