LM-series

LM-4228

Gantry machining center

Suitable for all kinds of large and medium-sized castings and structural parts.

Feature

The sliding seat adopts a three-rail structure design, which has a strong anti-rotation torque, and at the same time increases the stability of the sliding seat to ensure that the precision will not be affected by forward tilt

Models with an X axis travel of more than five meters are equipped with a ball leadscrew support device as standard to prevent the deformation of the ball leadscrew from affecting the machining precision.

Optional vertical and horizontal, chain and disc tool magazines are available for multi-step processing of complex parts, significantly improving processing efficiency.
