Description
This heavy duty lathe machine CW6280B is suitable for internal and external turning, tapping, and other rotating faces, metric, module and inch threads, as well as drilling and pulling oil slot. This heavy duty lathe machine could machine steel, casting, nonferrous metals and etc. And the dimensional accuracy of the machined workpiece could reach to IT6-IT7, and with good surface roughness. Also with a handle breaker, is easy to operate, safe and reliable.
Features
- The sidewall of the bed is constructed with double-rib Plates, and the shape of the internal ribs is of box type and bevel ribs combination. The rigidity is higher than that of ordinary lathes. The precision is stable. And these lathes can carry out strong force cutting.
- On the apron, there is a device, operated by a single lever, used for a rapid traverse of the carriage. The spindle’s braking and rotating direction change are controlled by a hydraulic system, or by hand operation, all to the user’s choice.
- The saddle guideway is glued by “TSF” soft belt wear-resisting materials.
- On user’s demand, we can equip the lathe with an automatic feeding mechanism. The top slide can be used independently for turning of the short cone. In combination with longitudinal feeding, it can also turn long taper surfaces.
