Hydraulic internal expanding pipe facing machine
Technical points and advantages of DP pipe facing machine
Precision cutting performance
Extreme high facing accuracy (dimensional accuracy ±0.05mm, beveled face roughness ra3.2) and fast facing efficiency (1~5 minutes).
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.
Carry out multiple beveling shape
V bevel X bevel J bevel
