Star Micronics eCA-S20 vs Star SV-38R
Star Micronics vs Star Micronics · Swiss-Type Lathes
Summary
The Star Micronics eCA-S20 and the Star SV-38R are Swiss-type lathes in different size classes, so they serve different jobs. Star publishes few comparable figures for this pair: maximum turning diameter and axis count.
The Star SV-38R takes bar up to 38 mm (1-1/2 in), against 20 mm (25/32 in) on the Star Micronics eCA-S20. On axes the two are level on paper: the eCA-S20 lists 10 axes, and the SV-38R lists up to 10, including Y1, Y2, C1 and C2. The choice is therefore about bar size, not axis count.
Specifications Comparison
| Specification | Star Micronics eCA-S20 | Star SV-38R |
|---|---|---|
| Max Turning Diameter | Ø20mm (25/32in) | ø38mm (1-1/2in) ▲ |
| Axes | 10 | Up to 10 (including Y1, Y2, C1, C2) |
Advantages
Star Micronics eCA-S20
- Sized for small-diameter bar work up to 20 mm (25/32 in)
- Lists 10 axes as its figure, where the Star SV-38R's row reads up to 10
- Aimed at parts with overlapping front and back operations
Star SV-38R
- 38 mm (1-1/2 in) maximum turning diameter against 20 mm (25/32 in)
- Suits bar work with milled, cross-drilled and off-center features
- Suits part families that need a large set of tools standing ready
Verdict
These machines serve different jobs, and bar diameter draws the line. Parts from bar above 20 mm (25/32 in), up to 38 mm (1-1/2 in), with milled and cross-drilled features belong on the Star SV-38R. Small-diameter work at or below 20 mm, with front and back operations overlapping, fits the Star Micronics eCA-S20. Axis count does not separate them: both tables stop at 10.
