Typical Applications
-
Designed for frequent setup changes in toolrooms and maintenance workshops where repeatability matters more than throughput.
-
General purpose lathe for turning of shafts, flanges, and bushes for cement, power, and steel plant workshops.
-
R&D applications in laboratory and defence engineering units.
-
Maintenance machining of couplings, pump shafts, and motor shafts in heavy industry plants.
-
Railway workshops for machining axles, pins, and repair parts.
Machine Description
Machine Description
- • All-geared precision centre lathe for accurate turning and finishing of small-to-medium mechanical components.
- • High grade grey cast iron bed conforming to IS:210 with guideways hardened to 380-400 BHN, ground, and precision-scrapped to maintain alignment and dimensional repeatability over long service life.
- • Case-hardened and ground alloy steel spindle, supported on precision taper roller bearings for low run-out and stable concentricity.
- • Universal feed gearbox providing a wide range of feeds and threading options without frequent gear changes.
- • Balanced rigidity and speed range, suited for precision machining rather than heavy material removal.

Configuration Notes
Machines of similar size can behave very differently in real workshops. For heavy duty lathes, performance is influenced mainly by:
- 1. What components you are machining (size, weight, condition).
- 2. How often will you use the lathe (occasional work vs continuous duty).
- 3. How the job is supported in operation (steady rests, overhang, handling).
