Introduction of CW series of large-scale lathe
The CW61100B / 61125B / 61140B / 61160B series of large-scale lathes have a capacity of workpiece of 6 tons. It can turn the end faces, outer circles, inner holes and metric threads, inch threads, modular threads, pitch threads, etc. The upper tool holder can be used for motorized turning of short tapers alone, and the upper tool holder can be used with longitudinal feed to coordinate motorized turning of long tapers. And can undertake drilling, nesting, boring and other processes. The machine tool has high power and strong rigidity, and can use hard alloy tools to perform thread cutting to process various ferrous and non-ferrous metals.
CW series of large-scale lathe main features
1.The overall bed with high rigidity.
The bed adopts integral casting structure. The internal ribs are reasonably laid out and have high rigidity. The guide rail adopts intermediate frequency quenching and grinding process. Adopting the anti-creeping guide plate technology on the sliding guide surface, the dynamic characteristics such as friction damping coefficient are in the best state, avoiding the occurrence of low speed crawling phenomenon.
2.High rigidity and high precision spindle.
The spindle box adopts a symmetrical structure to make the thermal deformation uniform and avoid the deviation of the spindle center. To reduce thermal deformation, the headstock adopts oil bath circulation lubrication. The front end of the main shaft adopts a three-way support structure with two-way angular contact ball bearings, increased accuracy and increased rigidity. The internal gears are quenched and ground to ensure accurate transmission and low noise. The spindle maintains a relatively stable accuracy during long-term operation.
