+GF+ MIKRON MILL S 400 PRECISION VERTICAL MACHINING CENTER

Technical Description

The +GF+ Mikron MILL S 400 is a high-precision 5-axis vertical machining center designed for demanding milling applications requiring exceptional surface finish, repeatability, and reliability. It offers a work envelope of 19.68 inches (X), 17.71 inches (Y), and 14.17 inches (Z), with five axes including rotary and swivel capabilities, enabling complex 3D contouring and multi-sided machining. The machine is equipped with a high-speed Step-Tec spindle delivering up to 42,000 RPM with a power output of 8.8 kW rated at 40% ED, utilizing an HSK-E40 taper for high-speed tooling and quick tool changes. The spindle features advanced thermal management via the OptiCool system, ensuring minimal thermal distortion and consistent accuracy even under extended machining cycles. The machine structure is built on a high-stiffness polymer concrete base combined with cast iron sliding carriages for superior damping and vibration control, supporting high dynamic accuracy and stability. Direct linear and rotary drives with direct path measuring systems provide excellent precision and rapid positioning, while intelligent software compensation and thermostabilized components maintain process stability regardless of ambient temperature fluctuations. The Mikron MILL S 400 integrates tool monitoring with vision-based ITM for reliable tool measurement with sub-2 micron accuracy, enhancing process reliability and surface quality. Controlled by the Heidenhain TNC 640 CNC, it offers high-speed rapid traverses and comprehensive thermal and dynamic error compensation. This machining center addresses a wide range of precision mold, die, and complex component manufacturing with high productivity and reduced cycle times, while energy-efficient modules reduce operating costs and environmental impact.
