Focusing on production:Providing the best choice for automotive components,electronic communication components, aerospace components, and precision mold manufacturing enterprises ect.
1.Specially designed for high-speed machining of spare parts, the entire series is paired with a direct style.
2.BT40-12000 spindle, low vibration and high-performance torque output, ensuring high speed and high feed.
3.The low center of gravity drive of the saddle improves stability during rapid displacement and stability of machining accuracy.
4.Adopting an ultra wide column design, it ensures excellent rigidity while maintaining long-term accuracy stability.
5.The horizontal and vertical dimensions of the spindle head adopt a 1:1.1 golden ratio structure, paired with a 6-slider design, greatly improving cutting ability and processing stability.
6.Unique shoulder mounted tool magazine installation method, with a standard configuration of 24 tool arms, to meet processing needs.
Different spindle structures can be replaced to meet various production needs.
Ensure axial positioning accuracy.
All three axes use C3 grade precision screws with pre tensioning design, effectively suppressing temperature rise and prolonging, ensuring repeated positioning accuracy.
The three axes all adopt P-grade roller type rail, which achieves high rigidity and high load capacity in four directions through contact between the rolling element and the sliding rail line.
The unique shoulder mounted tool magazine installation method can be matched with different types of tool magazines to meet processing needs.
