Product Details
45º overall tilting bed design, high rigidity, smoother cutting;
Finite element structural analysis shows that the casting rib layout is reasonable and the stress effect is good;
The X/Z axis screws are all pre-stretched structures, which can reduce the impact of temperature rise on screw accuracy during processing. The servo motor is directly connected to drive the high-speed and silent ball screw;
X and Z-axis linear rolling guides have good dynamic characteristics, stable processing accuracy, high rapid movement speed and high processing efficiency;
The tailstock adopts rectangular guide rails with good load-bearing rigidity. It has an upper and lower layered structure. There is a micro-adjustment device between the upper and lower layers to facilitate fine adjustment of the tailstock top rotation center along the X-axis direction. The standard live top structure tailstock is hydraulically driven by the sleeve;
Integrated high-rigidity spindle box, low noise, high precision and long life;
Imported functional components, equipped with imported servo AC motors, have good system performance, good controllability, and high spindle indexing accuracy;
A wide range of options: such as feeder, hollow chuck, material catcher, enlarged spindle through hole, programmable tailstock, tool setter, hydraulic center frame, etc.
