03

Climatic design: UHL4 as per GOST 15150-69.

02

The extensions centralizes and holds the pipe in place during machining thus preventing radial runout.

01

The device extends the length of short pipes if the length of the pipe to be machined is less than the distance of the turning machine front and rear chucks
Principle of operation:

  • Position the pipe to be machined in the chuck No. 1 of the turning machine, and the extension (pos. 1) in the chuck No. 2;
  • Rotate the control wheel (pos. 2) around its axis and the threaded feed shaft (pos. 3) respectively;
  • Rotation of the feed shaft causes the threaded nut (pos. 4) to move along the rotation axis;
  • Supports (pos. 5) connected with link rods (pos. 6) in a swivel couple with the enclosure and the feed nut move in the plane perpendicular to the rotation axis;
  • Supports fitted with replaceable plates (pos. 7) centralize and hold the pipe in place during the machining and prevent its radial runout;
  • The enclosure is fitted with stop bolts (pos. 8) preventing accidental rotation of the control wheel during the machining of the pipe. It is possible to improve the hold by tying the control wheel with safety wire.
