Main application & structure
1. This machine tool is a two-axis linkage CNC deep-hole internal grinder, which can grind the inner round hole of the work piece, the step hole, the inner cone hole, the inner circle end face and the outer circle end face. It has the functions of automatic feed, automatic rough grinding, fine grinding, automatic tool withdrawal, automatic dressing of grinding wheel, automatic compensation and so on.
2. The machine bed is formed by wear-resistant iron castings, fixed by work piece box, reciprocating movement of worktable and feed mode of grinding wheel frame.
3. The machine tool adopts Siemens programmable numerical control system to automatically correct and compensate the grinding wheel, automatically feed the work piece during grinding, automatically carry out intermediate dressing, correction compensation, grinding compensation, fine grinding delay, automatic tool withdrawal and so on.
4. The feed guide rail of grinding wheel frame and the reciprocating motion guide rail of work table all adopt high rigidity and high precision rolling linear guide rail. The machine tool is a fully closed protective waterproof cover, equipped with fog absorption device, rear knapsack type electric cabinet and front rotary operating table.
5. The work box can move left and right on the base skateboard, and can rotate the angle, and the work piece spindle adopts sleeve spindle.
6. This machine tool is equipped with Ethernet interface for users to expand their functions. The main electrical components are Schneider, and the electric box is equipped with special air conditioners and special lights.
