Features

Pipelathe unique design

KRAIS Tube Expanders

All the Lathe series machine design is based on long steel spindle which assure maximum rigidity because the locking shaft is fully mounted into that spindle instead partially into the main aluminium body what is casing adverse vibration due to a lot of tension on it.

Powerful motor unit

KRAIS Tube Expanders

Powerful and efficient drive dedicated for our Lathe series beveling machines. 0-5 rpm and 12500 Nm (9200 ft.lbs) torque on the cutter blade is a standard feature.

6-points locking jaws

KRAIS Tube Expanders

150 mm (5,9”) shaft, assures rigidity when machining heavy wall pipe. The jaws are fully contained within the shaft with no need for retaining springs or O-rings that easily brake or get lost

Expandable holders

KRAIS Tube Expanders

Extended tool holders can increase the range of the machine due its extremely powerful pneumatic drive.

Heavy duty pendant

KRAIS Tube Expanders

Machine is equipped with a heavy duty pendant. This can be attached to both sides of the motor for operator convenience.
