A new possibility for error is introduced every time a part is switched from one machine to another in the manufacturing process.

The gantry-type Mikron MILL P 800 U ST (Simultaneous Turning) aims to minimize those errors by combing milling and turning in a single machine.

The milling-turning center features an 800mm x 800mm table (31.5” x 31.5”) with a maximum load of 800kg (1,763lbs), X-axis travel of 800mm (31.5”) and an 800RPM C-axis rotation speed. It also incorporates a 20,000 RPM HSK T63 spindle, the industry’s fastest for a milling/turning machine of this size.

If you’re interested in a faster spindle (for CNC routers), check out the 40,000 RPM PDS XLC70.

Water-cooled torque motors on the A-axis and C-axis are intended to ensure milling/turning accuracy and stability. The MILL P 800 U ST is automation-ready and equipped with pallet changers for two, seven, nine or 12 pallets.

The machine is capable of four-axis simultaneous turning, which is often required in applications where the cutting tool must be positioned at a 90-degree angle to the workpiece surface in order to avoid tool shape errors.

Its gantry-type configuration is designed to service the automotive, aerospace, energy and general manufacturing industries. The table is fully accessible without rotating, further reducing the chance of errors.

The milling-turning center’s small footprint (137” x 118”) means it can be easily integrated into existing lines, especially since it’s designed to do the work of two machines.
