Machine Features

1.This CNC pipe thread lathe is newly designed.
2.The bed is made of original three-layer wall structure, and the rear wall is arranged with 12° slope. The width of the guide rail of the bed is 550mm. It is super-audio quenched and precision grounded to ensure the accuracy and service life of the machine.
3.The integral gearbox type spindle unit, two-speed inverter, stepless in the gear; the main motor is Beijing CTB spindle servo motor, which not only meets the requirements of thread finishing, but also achieves efficient cutting. It is completely different from the CNC lathe that has been modified on the basis of ordinary lathes.
4.The application of quenching precision grinding gears and high-quality bearings ensures that the machine noise is good.
5.The headstock adopts a strong external circulation cooling lubrication system, which not only reduces the temperature rise of the spindle, but also effectively keeps the headstock clean and lubricated.
6.The X and Z axes adopt high-precision ball screw direct drive and lead screw prestressed tension structure. The Z-axis screw nut hanger is an integral casting structure. The guide rail is attached with YT soft belt. The width of the bed saddle skateboard is 300mm and the length is 550mm. Generally, the size of this type of machine is 280 and 480mm, which improves the guiding precision and the precision of the machine tool, and effectively improves the service life of the machine.
7.The main drive gear of the machine tool is manufactured by SMTCL; the protective sheet metal is designed independently and made of standard cold-rolled steel plate.

Specification

Machine’s Main Parts

1.Machine body
The width of the bed rail is 550mm, the material is HT300 high-strength gray cast iron; the super-audio quenching reaches HRC52 or above, and the roughness is up to Ra0.63 by high-precision guide rail grinding machine, which has high precision and wear resistance. The machine bed is a three-layer wall structure, and the rear wall is arranged with a 12° slope, which can guarantee the rigidity of the machine tool for a long time.
2.Headstock
Integral gearbox spindle unit, spindle servo motor, two-stage mechanical speed regulation. The speed range is wide, which not only meets the requirements of thread finishing, but also achieves efficient cutting. The application of quenching precision grinding gears and high-quality bearings ensures low noise and good sound quality. The headstock uses a powerful external circulation cooling lubrication system, which not only reduces the temperature rise of the spindle, also effectively maintains the cleanliness and lubrication of the headstock.
The spindle of the machine tool is made of 45-quality steel, which is processed and precision ground to ensure the accuracy and stability of the spindle.
3.Tailstock
The machine is equipped with a φ100 spindle and a Mohs 5 top tailstock. The tailstock body and the spindle are extended to improve the accuracy and stability of the tailstock spindle.
4.CNC Tool Holder
Adopt the YTUM four-station vertical electric tool holder AK21240X4C. It has the characteristics of high precision, stable rotation and simple operation.
5.Double-axis feed
Both the X and Z axes adopt high-precision ball screw direct drive and lead screw prestressed tension structure, which adopts precision ball screw bearing positioning and support; Z-axis screw nut hanger is an integral casting structure.
6.Others
The machine is equipped with three-color warning lights, electronic MPG, ffront door limited switch, separated foot stand, toolbox, spindle jog function and random files.
