1, the spindle box welded plate structure, and rational layout ribs; spindle alloy steel, heat treatment and precision grinding; bearings imported high-precision tapered roller bearings, the use of oil lubrication cooling.

2, the main motor drives the transmission shaft through the belt, driven by a pair of helical gears to rotate the main shaft and cutter head; the main motor adopts frequency conversion motor, which can be stepless speed regulation.

3, The feed mechanism is driven by the servo motor through the ball screw. The guide rail adopts the rolling guide. The ball screw is pre-stretched, greatly improving the resistance to thermal deformation, ensuring the rigidity and accuracy of the feed shaft and effectively improving the cutting machine Processing accuracy.

4, feeding system by the servo motor through the belt, ball screw drive, guide rail rolling. Ball screw assembly pre-stretched, greatly improving the resistance to thermal deformation, feeding accuracy of up to 0.01mm. The hydraulic clamping structure is driven by a hydraulic cylinder for the clamping feed of the steel pipe. In order to ensure the synchronization of the movement of the two clamping arms, a pair of synchronization mechanisms are arranged between the two clamping arms.

5, forced cooling of the hydraulic system to reduce oil temperature, to ensure the normal operation of the machine.

6, the main purchased parts such as bearings, hydraulic, lubrication, lighting, cooling system, transmission belts, electrical components, ball screw, rolling guide, etc. are selected well-known brands at home and abroad.
