Product Details

QKA1246pipe thread CNC machine description

This series of lathe machine bed adopts high standard cast iron (HT300) one molding casting, guide way width is 1100mm, processed by the second aging treatment, it owns the characters of stable performance, good rigidity, anti-vibration ability. Spindle bore diameter is 465mm, machined pipe diameter is 460mm. Two-point supported spindle with precision heavy-duty bearing, spindle speed is automatic segmented gear shift control by the M code, stepless within segment controlled by the S code, achieving stepless speed and constant linear cutting. X-direction and Z-direction using precision ball screw assembly ensures a high processing accuracy, positioning accuracy and accuracy of retention. longitudinal (Z) feeding carried out by AC servo motor mounted on the left side of feed box drives the ball screw via planetary gear box. (X-direction) feeding carried out by AC servo motor mounted on the saddle back drives the ball screw via flexible coupling. Before delivery all the lathe machines are tested with British RENISHAW laser detector for dynamic accuracy detection and compensation, ensured they have a high positioning accuracy and repeat positioning accuracy. Standard configuration is with the 4-station turret which is free lifting and tool changes quickly and easily, a vertical 4,6 station and horizontal 6,8 station and other electric turret can be chosen. Tailstock is electric motor driven type, it can move automatically and quickly, manual type tailstock also can be selected according to users’ need. hook drag. The main motor is high-power AC variable frequency motor with frequency converter, the output is large and big range of speed. Equipped with doubleΦ1000mm manual independent 4-jaw chuck. CNC system uses the internationally renowned FANUC, SIEMENS or China GSK980TD AC servo control system.

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.
