CNC boring machine DG520G

■ The machine is consisted of machine base, column, a spindle box (slide), fixtures, chip and other components.

■ Spindle box and boring tool movement are driven by servo motors, ball screws and linear guide.

■ Spindle rotation is diven by spindle motor via a timing belt.

■ Fxied type of fixture on the table, with unloading cylinder to pull out the workpiece after boring.

■ Achieve broing process through spindle tool’s rotation and reciprocation up and down.

■ Overall shelled machine for large flow cooling machining, which can effectively ensure the boring accuracy.
