GMC4252b bridge type high-speed gantry machining center

Advantages and features:
The overhead gantry structure covers about 56% of the area of the traditional mobile workbench type. The X and Y axes adopt heavy-duty linear rolling guides, and the Z-axis square ram touches the hard rail structure on eight sides.
The fixed table doubles the load-bearing capacity and the machining characteristics of the machine are not affected by the quality of the workpiece. The “line-hard” combination of the vertical orthogonal linear guide of the beam and the sliding hard guide.
The X-axis of the beam is designed with a double column and a center of gravity drive to improve the stability of machining.

Spindle temperature controlled water cooler
X-axis synchronous dual drive with full closed-loop grating scale
Double spiral and transverse chain chip conveyors
Three-axis German Alpha precision planetary reducer
