Flat bed lathe

This series of lathes has a semi closed loop control function. The load-bearing capacity can reach up to six tons, suitable for processing various complex shaped shaft, sleeve, and disc parts, such as turning inner and outer cylindrical surfaces, conical surfaces, circular arc surfaces, end faces, cutting grooves, chamfering, threading, etc. It is an ideal large-scale mechanical processing equipment.

Main structural features:
1. Bed body: integral box structure, made of high standard cast iron (HT300) secondary molding casting, with a guide rail surface width of 755mm;
2. Spindle box: able to adapt to heavy cutting processing, gears undergo high-frequency quenching and precision grinding, with high precision, smooth operation, and low noise; The spindle has a large diameter and is supported by precision heavy-duty bearings in a three-point manner, ensuring stable rotation. It can be used for both heavy cutting and precision turning; It can achieve continuously variable speed and constant linear speed cutting.
3. Feed: Precision grinding grade ball screw pairs are used in the X and Z directions to ensure high machining accuracy, positioning accuracy, and accuracy retention; Each pair of motion is automatically lubricated by a centralized intermittent lubrication system; Longitudinal (Z-direction) feed: 1000-6000 specifications are fed by an AC servo motor installed on the left side of the feed box through a high-precision planetary reducer to drive the screw feed, while specifications above 6000 are fed by gear rack transmission; Machine tools have high positioning accuracy and repeatability.
