Such heavy duty lathe machines have following features:
1. mainly suitable for various cutting jobs, such as internal and external cylindrical surfaces turning, facing and various pipe thread cutting.
2. can also be used for drilling, boring trepanning etc.
3. The compound rest slide can be used individually by power for cutting a 300mm taper surface, or used with aid of longitudinal feed motion of the carriage by power for cutting long taper surface.
4. fine appearance, concentrated control arrangement for easy operating and convenient maintenance.
