DN Solutions FM 200 5AX LINEAR

The DN Solutions FM 200 5AX LINEAR is an ultra-high-speed, high-precision 5-axis machining center built around linear motor drives and a screaming 42,000 RPM spindle. This isn't your typical production 5-axis — it's a precision instrument designed for micro-machining, ultra-fine finishing, and small complex components where surface finish and accuracy matter more than raw material removal rate.

Axis travel is compact at 200 x 340 x 300 mm (7.9 x 13.4 x 11.8 in) on X/Y/Z, with a 200 mm (7.9 in) diameter rotary table. This machine isn't trying to swallow large parts. It's purpose-built for small, intricate workpieces — think medical micro-implants, watch components, electronic connectors, precision optics mounts, and dental prosthetics.

The 42,000 RPM spindle delivers 10 kW (13.4 hp) and 6.5 Nm of torque through an HSK-E40 taper. Those numbers tell you exactly what this machine is: a high-speed finisher, not a roughing platform. The HSK-E40 interface is standard in the micro-machining world for its concentricity and balance characteristics at extreme RPMs. At 42K, you're running micro endmills at surface speeds that produce mirror-like finishes without secondary polishing.

Linear motor drives on all axes eliminate the backlash, stick-slip, and thermal growth associated with ballscrew systems. That translates to sub-micron positioning accuracy and mirror-smooth axis reversals that show up directly in surface finish quality. Direct-drive motors on the rotary axes complete the picture — there's no mechanical drivetrain between the motor and the axis on any axis of this machine.

The symmetrical gantry structure uses anti-vibration materials to keep the machine thermally and dynamically stable during high-speed operation. A 24-tool magazine provides adequate capacity for micro-machining jobs. The Heidenhain controller is standard — the right choice for this class of precision work, with its native support for spline interpolation and high-speed contouring cycles.

At 7,000 kg (15,432 lb) in a compact 2,225 x 1,972 mm (87.6 x 77.6 in) footprint, the FM 200 5AX LINEAR packs heavy mass into a small package. That mass-to-travel ratio helps suppress vibration at the microscopic level. This machine competes with platforms from Kern, Roders, and Yasda in the ultra-precision 5-axis segment.
