Description

Used Milling Machine KRAFT VM-3218 with Fanuc controller.

Features:


One-piece cast iron machine bed and one piece cast iron bridge yield in highest rigidity for precise machining results. The frame, stress-relieving designed, provides a stable performance of the machine.

The whole structure was analyzed by FEM to optimize rigidity and precision.

Preload roller linear guide ways with P grade allow max. Loading but with a lower friction coefficient (0.003-0.006). It supplies smooth running thanks to optimized roller recirculation and guidance, saving energy consumption.

C3 grade double nut ball screws provide precise cutting, even for heavy loads.

A BF gear box with a 26 KW motor generate 662Nm torque for powerful cutting, thus reducing machining time.

Two coil chip conveyor and one chain chip conveyor remove the chips effectively.

The machine is operated via an operator's panel, designed by Sky Master and made in Taiwan
