Advantages of hyperlathe

KRAIS Tube Expanders

UNIQUE SHAFT DESIGN

70 mm (2,75”) 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.

KRAIS Tube Expanders

POWERFUL MOTOR UNIT

Powerful and efficient drives dedicated for our Lathe series beveling machines. 11 rpm and 3850 Nm (2840 Ft.Lbs) torque on the cutter blade is a standard feature.

KRAIS Tube Expanders

6 POINTS LOCKING JAWS

The innovative, 6 points jaws, effectively lock the machine within the pipe, allowing safe, efficient and smooth processing of the tube end.

KRAIS Tube Expanders

HEAVY DUTY PENDANT

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

Optional motor units

KRAIS Tube Expanders

PDE MOTOR

The PipeLathe can also be supplied as an electric version, with a 3200 Watt heavy duty motor.

KRAIS Tube Expanders

PDH MOTOR

Optional super strong hydraulic motor. Constructed on the basis of a small hydraulic motor and multistage planetary gear box. HyperLathe version generates 11 rpm and up to 8200 Nm (6050 Ft.Lbs) torque on cutter blade at constant cutting speed.
