Star Micronics eCA-S20 vs Tornos DECO 20a
Star Micronics vs Tornos · Swiss-Type Lathes
Summary
The Star Micronics eCA-S20 and the Tornos DECO 20a are Swiss-type lathes in the same size class. The makers publish few comparable figures for this pair, maximum turning diameter and axis count, and on both rows the machines sit almost level.
The Tornos DECO 20a takes bar up to 20.5 mm (0.807 in), a fraction more than the 20 mm (25/32 in) of the Star Micronics eCA-S20. The eCA-S20 lists 10 axes, and the DECO 20a lists up to 10. The table alone will not settle the choice between them.
Specifications Comparison
| Specification | Star Micronics eCA-S20 | Tornos DECO 20a |
|---|---|---|
| Max Turning Diameter | Ø20mm (25/32in) | 20.5 mm (0.807 in) ▲ |
| Axes | 10 | Up to 10 |
Advantages
Star Micronics eCA-S20
- Lists 10 axes as its figure, where the Tornos DECO 20a's row reads up to 10
- Aimed at small-diameter bar work with overlapping front and back operations
Tornos DECO 20a
- 20.5 mm (0.807 in) maximum turning diameter against 20 mm (25/32 in)
- Suits medical, watch, connector and aerospace fastener parts in titanium, stainless steel and brass
Verdict
On the published rows these two do the same job: bar of about 20 mm and up to 10 axes. A shop running stock right at the limit gets slightly more room from the Tornos DECO 20a at 20.5 mm (0.807 in). Otherwise decide on the intended work: the Star Micronics eCA-S20 is aimed at parts with overlapping front and back operations, the Tornos DECO 20a at medical, watch and connector parts in titanium and brass.
