230MM CNC Pipe Threading Oil Country Lathe

QKP1223pipe thread CNC machine description

This series of lathe machine bed is overall structure (6000 long is two pieces ), uses of high standard cast iron (HT300) one molding casting, guide way width is 600mm. After the second aging treatment, it has the feature of stable performance; Anti-vibration ability. Spindle bore diameter is 240mm, pipe diameter can be processed is 230mm. Spindle is supported by two-point with precision heavy load bearing. Automatic segmentation speed controlled by M code, stepless speed within segment controlled by the S code, achieving stepless speed and constant linear cutting. The X-direction and Z-direction use the precision grinding grade ball screw, ensured a high processing accuracy, positioning accuracy and accuracy of retention.

Longitudinal (Z) Feeding: distance between centers for 1000mm-1500mm: the AC servo motor mounted on the left side of the feed box is connected directly to the longitudinal ball screw via a coupling. 2000mm-3000mm: AC servo motor mounted on the left side of the feed box plus reduction gears(1:3) drive the ball screw directly via a coupling.

4000mm-6000mm: AC servo motor mounted on the left side of the feed box plus reduction gears(1:4) drive the ball screw directly via a coupling.

Horizontal (X-direction) Feeding: the AC servo motor mounted on the back of the bed saddle is connected to horizontal ball screw via coupling.

Before delivery all lathe machines should be tested by British RENISHAW laser detector for dynamic accuracy detection and compensation, so the lathe machine has a high positioning accuracy and repeat positioning accuracy. All the lathe machines are equipped with electric turret, free lifting, tool change quickly and easily, there are vertical 4 and 6 station and horizontal 6 station and other electric turret for choose. The main motor is 15kw high-power frequency main motor. Equipped with one ?630 manual three-jaw self-centering chuck and one ?630 manual four-jaw independent chuck, CNC system uses the internationally renowned FANUC 0i, SIEMENS or China GSK980TD AC servo control system. The lathe machine adopts semi-closed protection or fully enclosed protection, equipped with emergency stop safety button, when the lathe machine suddenly encountered a sudden power failure or other failures, due to the special design of the control circuit, it can be self-protection to ensure that the lathe machine and personnel safety. The operator panel is about 1500mm from the ground, highly moderate, ergonomic, pleasant and easy to operate and understand the operation of the machine.

This series of lathe machine is mainly developed for the turning of oil field pipe thread, it is not only suitable for all kinds of pipe thread turning, but also can be used for ordinary CNC lathe, suitable for processing complex shape of the shaft, sets, disk parts, such as turning inside and outside cylindrical surface, conical surface, circular surface, end face, chamfer. Especially for multi-species, small batch of turning processing, process adaptability, high processing efficiency, low scrap rate, good product consistency, easy programming, simple operation, reducing the technical requirements of workers, it is the ideal medium mechanical processing equipment.
