Continuous Machining of Complex Forms

GF Machining Solutions' Mikron MILL P 500 U high-performance machining center offers increased accuracy and process reliability.

GF Machining Solutions' Mikron MILL P 500 U high-performance milling solution is designed to provide powerful and dynamic material removal capabilities and high stiffness.

The Mikron MILL P 500 U enables continuous machining of complex forms and tough materials while shortening process time. Its advanced thermal stability provides enhanced precision over long machining periods. Furthermore, it offers increased competitiveness by integrating smart automation and is designed to provide the process reliability essential to precision parts manufacturing segments such as aerospace and machinery as well as automotive moldmaking.

The Mikron MILL P 500 U's new wireless vibration sensing application is designed to reduce errors. Especially important for industries requiring the highest precision, such as aerospace, this new solution uses 5G technology to communicate between sensors and machines to adjust the speed and motion of the milling head to minimize vibrations and maximize throughput.

High Accuracy, Process Reliability

The Mikron MILL P 500 U offers accuracy and process reliability due to the machine's thermostability and symmetrical design, even over long production periods.

The Mikron MILL P 500 U's 1.7 g acceleration, 36 kW Step-Tec Spindle, rotary tilting table capacity of up to 600 kg, and workpiece diameters up to 707 mm are features engineered to provide constant dynamic machining as well as 100% flexibility in part production.

The rotary tilting table is available in several variations: T-slot tables accommodating a payload of 200 kg, 400 kg or 600 kg, as well as pallet tables accommodating a payload of 200 kg, 400 kg or 600 kg. Incremental, direct angle measuring systems are mounted on the swiveling and circular axes to offer high positioning and repeat accuracy. Both axes are driven via water-cooled torque motors: one for T-slot tables, two for pallet tables on the A-axis and one on the C-axis. These direct drives are designed to provide precise, simultaneous operations. For heavy-duty machining, the rotary and swivel axes can be clamped and, for best machining stability, the swiveling axis has clamping on both side supports.

"With the 20,000 RPM Step-Tec HPC190 Spindle with HSK-A63 tool interface, manufacturers extend their flexibility and benefit from the best universal spindle selection for stiffness, power, speed and safety with machine and spindle protection (MSP)," said a company spokesperson. Also available is Step-Tec's 36,000 RPM HVC150 motor spindle with HSK-E50 tool interface. This spindle solution is advantageous for moldmakers working with small cutting tools. The dynamic 1.7 g acceleration allows enhanced surface finishes.

Higher Productivity

"Precision parts producers and moldmakers can more than double productivity with the 11 m sq. Mikron MILL P 500 U's accommodation of limitless integrable automation solutions through the back," said the spokesperson. "This means users can achieve efficient, unmanned third-shift productivity due to an array of automation choices, as well as direct System 3R robot loading of pallets to the table and the availability of parts handling solutions. For example, manufacturers' productivity and agility are increased with System 3R's JobToolManagement (JTM) user-friendly software for one machine with an integrated pallet changer." With JTM, the user assigns numerical control (NC) programs to pallet positions by dragging and dropping on a touchscreen.

Decreased Down Time

Mikron MILL P 500 U users can cut their downtime from hours to minutes with GF Machining Solutions' Industry 4.0 supporting smart modules such as Machine Spindle Protection (MSP) and Customer Services' rConnect modular digital services including Live Remote Assistance (LRA).

MSP protects the spindle and machine geometry while maximizing machine uptime to reduce costs associated with unexpected spindle collisions. Collisions usually occur when a new CNC program is first executed. MSP protects the machine and spindle during job set-up by making it possible to absorb axial and lateral collisions and then restore accuracy. The spindle can return to normal operations without any specific maintenance or recalibration, ensuring almost no downtime or collision-related costs.

Users' productivity, flexibility and autonomy are further accelerated by the Mikron MILL P 500 U's rConnect readiness. Manufacturers choose the GF Machining Solutions digital services that best fit their needs. LRA, for example, delivers secure, direct, customer-authorized real-time remote assistance by connecting the customer with the local diagnostics center and GF Machining Solutions' Technical Units. With LRA, customer services can inspect a machine tool remotely, with diagnostics carried out by the customer's own technician or a GF Machining Solutions expert.
