GMB3020 High Performance Automatic Gantry Type CNC Milling Machine Vertical Machining Center From China for Sale
Product Description
Main Features:
1. In line with design concept of driven at the center of gravity, the machine equipped with double balance counter weight. Meanwhile the center of ram falls on the center of axis, with equalized ram guideway allocation. The design eliminates bending of ram guideway when ram moves up and down. Consequently Z axis can perform with high stability and accuracy.
2. Equipped with oil chiller, cycle cooling source for spindle unit and motor cabine.
3. Equipped with heat exchanger, the electric cabinet can abstrcat heat efficiently during work.
3. Equipped with heat exchanger, the electric cabinet can abstrcat heat efficiently during work.
4. Lubrication station is controlled by CNC system which can test and alarm automatically.
