Hydraulic Internal Expanding Pipe Facing Machine

Product Detail

Hydraulic internal expanding pipe facing machine


Technical points and advantages of DP pipe facing machine

1. Precision cutting performance

Extreme high facing accuracy (dimensional accuracy ±0.05mm, beveled face roughness ra3.2) and fast facing efficiency (1~5 minutes).

1. Quality process control

There are 35 working processes to make one part – main axis, from raw material inspection to metallographic analysis after material heat treatment, from dimension measurements after hard chromium plating.

1. Carry out multiple beveling shape






 V bevel               X bevel              J bevel
