Full 5-Axis Milling Machine with Glass Scale Feedback

The GEN MILL 5X-12 is a high-performance full 5-axis simultaneous milling machine that features Heidenhain glass scale feedback in all 5 axes for high accuracy.

The 12.6" platter diameter tilting rotary trunnion table is driven by a precision worm-gear and has 150° of tilt motion and 0.001° indexing resolution. "The 5X-12 5-axis CNC eliminates set-ups by allowing operators to machine multiple sides of the workpiece in just one operation, as well as allowing them to handle parts that require full 5-axis simultaneous machining," said a company spokesperson.

Standard features include a 12,000 RPM high-performance BIG-PLUS dual-contact precision ground #40-taper spindle for extra tool rigidity and accurate tool length repeatability, as well as extended tool life. The coolant system provides 300 PSI through-the-tool and a separate coolant pump for chip washdown that efficiently moves the chips into the included belt-style chip conveyor. A 40-tool chain drive twin-arm tool changer delivers tools in 1.7 seconds (tool-to-tool), providing ample tooling availability for complex workpieces. Rapid traverse rates of 1,417 IPM reduce cycle time for efficient production. High-speed synchronous rigid tapping is another included production enhancement.

"The added stiffness provided by the heavy-duty cross-roller style way system in the 3 linear axes provides the needed rigidity and enhanced cutting accuracy and helps extend tool life," said the spokesperson. "The heavy-duty cross-roller way system provides over twice the rigidity offered by the standard ball-style linear ways used in typical machines. The machine is constructed of all certified premium grade high-density Meehanite castings and weighs over 15,700 lbs. for superb vibration dampening. The wide spacing of the ways offers the optimal guide ratio for the moving elements, further enhancing the rugged design of the machine for accurate and heavy-duty machining."

The Mitsubishi M850 CNC controller is suited to the demands of high-speed machining that is a requirement for five-axis work, according to the company. The M850 features 270,000 blocks-per-minute processing speed with a 2,700 block look-ahead with NANO smoothing, and includes a 32 GB data server to help ensure a seamless flow of data to produce a smooth and accurate toolpath. Mid-program restart can be completed in a variety of circumstances, such as tool breakage or after a power outage or other interruptions for quick and efficient recovery.

"The rigidity of the high-strength cast iron frame provides a high-strength cutting platform with superior vibration dampening for improved surface finish and extended tool life," said the spokesperson. "The blending of strength with speed provides the ultimate value enhancing combination with the 12,000 RPM BIG-PLUS spindle, making the machine ideal for materials like aluminum and steel, and the strength of the cross-roller ways provide the rigidity for efficient machining of Inconel and stainless. The GEN Mill 5X-12 was designed to provide the results shops are looking for to efficiently process their multi-faced or 5-axis work profitability."
