Star Micronics eCA-S32T vs Star Micronics SB-12R Type G
Star Micronics vs Star Micronics · Swiss-Type Lathes
Summary
The Star Micronics eCA-S32T and the Star Micronics SB-12R Type G 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 the control.
The Star Micronics eCA-S32T takes bar up to 32 mm (1-1/4 in), against 13 mm (33/64 in) on the Star Micronics SB-12R Type G. The controls differ too: the eCA-S32T's is listed as Motion Control System, while the SB-12R Type G runs a Fanuc 0i-TD.
Specifications Comparison
| Specification | Star Micronics eCA-S32T | Star Micronics SB-12R Type G |
|---|---|---|
| Max Turning Diameter | Ø32mm (1-1/4in) ▲ | 13 mm (33/64 in) |
| Control | Motion Control System | Fanuc 0i-TD |
Advantages
Star Micronics eCA-S32T
- 32 mm (1-1/4 in) maximum turning diameter against 13 mm (33/64 in)
- Suits complex bar parts that need many tools across two turrets, with back-end work at full bar size
Star Micronics SB-12R Type G
- Fanuc 0i-TD control, a fit for shops that already run Fanuc
- Sized for small parts from bar up to 13 mm (33/64 in), including long, thin parts through the guide bush and short parts run without it
Verdict
Bar size splits these two cleanly. Complex parts from bar up to 32 mm (1-1/4 in) that need many tools across two turrets belong on the Star Micronics eCA-S32T. Small parts from bar up to 13 mm (33/64 in), long and thin or short enough to run without the guide bush, belong on the Star Micronics SB-12R Type G, which also suits shops standardized on Fanuc with its 0i-TD control.
