Equipment Highlights
● The bed adopts one-piece welded parts, and the column adopts high-grade cast iron casting, which has high precision stability, strong shock absorption capacity, 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 table rotation is supported by high-precision special turntable bearings, and the rotation is driven by servo motors and reducers to ensure the accuracy and stability of rotation.
● The angle of the grinding head and the table is adjustable, and the angle is convenient to detect, which can adapt to different continuous feed grinding methods.
●Equipped with a strong magnetic workbench, and controlled by the program.
● The Z-axis adopts precision ball screw and stable and reliable servo system, so that the upper and lower feeding tools maintain high precision and high stability.
