Precision Internal Finishing Machine

1.1 Machine tool processing scope

Machining aperture range: Φ50-Φ800

Maximum machining hole depth: 4m

Maximum workpiece length: 4m

The workpiece is fixed and the tool is rotated during machining.

1.2 Function and use of machine tool

Used for finishing all kinds of hydraulic cylinders, cylinders and other cylindrical deep hole parts.

It can be honed as a whole or partially. During local honing, the taper, ellipticity and local aperture errors of the workpiece can be corrected.

The expansion and contraction of the honing head can be controlled by servo motor, which can realize both constant pressure feed and quantitative feed of the honing head.
