PowerMill 3117 CNC milling machine

PowerMill 3117 CNC milling machine was built in 2019 in Poland by Mizera Automation. The machine’s welded steel profile structure, together with the large vacuum table, guarantees excellent stability and rigidity while machining workpieces made of steel, aluminium, as well as wood and plastics. The X/Y/Z axes are equipped with servo drives with RTE (Real Time Ethernet) protocol communication capability, achieving high repeatability of movements.

Workpieces are machined with the highest precision and speed, thanks to the use of HSM (High Speed Machining) technology. The extremely powerful spindle of the milling machine operates at a maximum speed of 24000 rpm. The milling machine has extensive equipment, comprising, amongst others, a stationary tool magazine with automatic tool changer, light curtains and a CNC controller with CAD/CAM software.
