Star Micronics eCA-S20 vs Star Micronics eCA-S32T
Star Micronics vs Star Micronics · Swiss-Type Lathes
Summary
The Star Micronics eCA-S20 and the Star Micronics eCA-S32T are Swiss-type lathes from the same maker, and Star publishes few comparable figures for this pair: the table holds one row, maximum turning diameter. That row is the headline difference.
The Star Micronics eCA-S32T turns bar up to 32 mm (1-1/4 in), against 20 mm (25/32 in) on the Star Micronics eCA-S20. Beyond bar size, the two are aimed at different work: the eCA-S20 at small-diameter parts with overlapping front and back operations, the eCA-S32T at complex parts that need many tools across two turrets.
Specifications Comparison
| Specification | Star Micronics eCA-S20 | Star Micronics eCA-S32T |
|---|---|---|
| Max Turning Diameter | Ø20mm (25/32in) | Ø32mm (1-1/4in) ▲ |
Advantages
Star Micronics eCA-S20
- Sized for small-diameter bar work up to 20 mm (25/32 in), where the larger capacity of the eCA-S32T would go unused
- Aimed at parts with overlapping front and back operations and light back-end work
Star Micronics eCA-S32T
- 32 mm (1-1/4 in) maximum turning diameter against 20 mm (25/32 in)
- Suits complex bar parts that need many tools across two turrets, with back-end work at full bar size in the sub spindle
Verdict
Bar diameter decides this one. Work above 20 mm (25/32 in) needs the Star Micronics eCA-S32T, which takes bar up to 32 mm (1-1/4 in) and suits complex parts that draw on many tools across two turrets. Shops whose parts stay at or below 20 mm, with front and back operations running together, are the natural buyers of the Star Micronics eCA-S20. With one published row to compare, any finer choice needs the maker's full specifications.
