Main components
Two (2) electric motor systems, two (2) Bed Head consoles, two (2) Bed Head feeding systems, one (1) work table platform, one (1) guiding rail and base base plate, two (2) Turkshead cutter platforms, two (2) pipe clamping systems, three (3) roller lifting systems, two (2) pipe stop and dispatch systems, one (1) Hydraulic control system and one (1) electrical controlling system.

Function of the above systems
Bed head console
Driven by electric motor, the Bed Head Console drives the turks-head cutter platform which in turn rotates and produces a revolving machining action. 

According to the size of the pipe, the revolving speed can be adjusted from 20 - 55 rev/min.

Guiding rail and work table platform
Both Guiding rail and Work Table are fixed on the base plate.  Electric motor and hydraulic motor coupled with reducers and worm gear control the feed speed, quick advance and retract movement of the turks-head cutter platform
Turkshead cutter plate & cutter inserts De-burr and bevel Cutter inserts are installed in the turks-head cutter
platform. The position of turks-head can be adjusted in accordance with the size of the pipe.

Clamping system
This is to hold the pipe firmly in position for machining.  Using hydraulic cylinders, the upper clamp shoe move to clamp the pipe with the lower clamp shoe.  Sizes of clamp shoes are Dia 508, 610, 720, 820, 1020, 1220, 1420,
1620, 1820, 2540, 3000 and 3200mm.

Roller lifter system
Transfer pipe to the work table, lift the pipe to the right height and position so that the clamping system can take over the clamp the pipe firmly for machining.

Lubrication system
Lubricant is sprayed during the machining process.  Frequent moving parts are sprayed periodically with lubricant.

Hydraulic system
An independent hydraulic system is used to control the movement and pressure of all cylinders.

Electrical system
The electrical system is to control all operation of the machine.
* PLC and electrical components are from SIEMENS
* Input electrical power 3 phase 50 Hz 380/220V

Process Flow
Pipe rolls and stops at the centre of the work table.
Roller lifter lifts the pipe 50 mm above the centre axis of the machine.

Rollers are driven by motor to position the pipe for clamping. Once in position, clamping action starts.

Roller lifter and the pipe are lowered together. When the pipe touches the lower clamp shoe, the upper clamp shoe starts moving downward to carry out the clamping action at both ends of the pipe. Ancillary clamping mechanism also started to prevent deformation of pipe ends.

When the pipe is firmly clamp
