2.     Machine function and characteristics

2.1 The machines use the 45°slanting rail body, high tonnage, the support surface of foundation is wide. Use synchronous pulley to drive main shaft. It has the features of low noise, no vibration, convenient to escape of chips. It can machining kinds of casing pipe threading and coupling etc less than ∮540mm.

 2.2 Use central lubrication device, lubrication is sufficient and reliability. Lubrication cycle is auto controlled, and equipped with oil-way distributor and pressure sensor, it can auto alarm if any oil way being impassable.

2.3 Independent water tanker with high power pump, have good cooking effects

2.4 With strict antiseep enclosed design, waterproof tighten.

2.5 With auto chip conveyor device.

2.6 75KW high-power 6-grade main motor, with 1:5 and 1:8 speed design, I shaft pull rod transmission shifting  . The large bore spindle is equipped with upper and lower tool holder to facilitate the fast processing of casing.

2.7 With 8-station electric turret, dual pneumatic chucks. 3-jaw pneumatic chuck (chuck hole φ550) is in front of the headstock, 5-jaw pneumatic chuck (chuck hole φ550)  is at the rear of the headstock. Fast clamping speed, strong rigidity, safe and reliable.

2.8 With FANUC Oi-TF control system

2.9 With hydraulic size fix device.
