Technical characters
Main Features:
1.The bed adopts an integrated welded part, and the column is cast with advanced cast iron, featuring high precision stability, strong shock absorption capability, and the arrangement of reasonable reinforcing ribs enhances the structure's strength. Welded parts and castings are both subjected to secondary annealing and shot blasting treatments to make the base components more stable and reliable.
2. The rotation of the worktable is supported by high-precision special rotary table bearings,driven by a servo motor and reducer to ensure rotational accuracy and smoothness.
3. The grinding head and the angle of the worktable can be adjusted, and it is convenient to check the angle, which can adapt to different continuous feed grinding methods.
4. Equipped with a strong magnetic suction worktable, and the magnetic attraction is controlled by a program.
5. The Z-axis uses a precision ball screw, paired with a stable and reliable servo system, to maintain high precision and high stability in the up and down tool movement.
