Product Features

High-Rigidity Structure Design

• T-shape structure design and ladder-type structure design of guideway on X-axis, combined with light-weight moving components can achieve quick response and high-precision machining.

• Featuring a column-moving structure, the machine enables precise movement of the cutting tool on X, Y, Z axis, rotation of the workpiece on A, B axis, and high-efficiency 5-axis machining capabilities.

In-House Developed Swiveling and Rotary Table

• The machining center is equipped with direct drive torque motor on A and B-axis. Due to non-mechanical transmission, non-backlash, high acceleration and deceleration, quick response time, the machine can maintain consistently high precision.

Roller Type Linear Guideway on X, Y, Z-axis
