Equipment Highlights

Equipment Highlights

●The bed adopts one-piece welding parts, and the column adopts high-grade cast iron casting, which has high precision and stability, strong shock absorption ability, and reasonable reinforcement arrangement improves the strength of the structure. Weldments and castings are treated by secondary annealing and shot blasting to make the basic parts more stable and reliable.

● The worktable rotation is supported by high-precision special turntable bearings, driven by servo motor and reducer to ensure rotation accuracy and stability.

●The angle of grinding head and worktable is adjustable, and it is convenient to detect the angle, which can adapt to different continuous feed grinding methods.

● Equipped with strong magnetic attraction workbench, and magnetic attraction is controlled by the program.

● Z axis adopts precision ball screw, with stable and reliable servo system, so that the upper and lower feed to maintain high precision and high stability.
