Our finishing sub-spindle for ST-10 through ST-25 turning centers – including Y-axis models – will not only make you more productive, and but will also provide new options for finishing the 2nd-op side of your parts.
This affordable A2-5 spindle is equipped with a 5.3-inch hydraulic chuck, and will fully synchronize with the main spindle to provide effortless “in-cycle” part handoff. This allows you to finish-off the “other half” of your part in a single setup – simply load up your raw workpiece, and the next time you open the door, you’ll have a finished part. A built-in part ejector propels the finished part into the optional parts catcher for automated operation.
Note: Not compatible with the VDI or BOT turret, or the tailstock option. The sub-spindle is compatible with the APL; however, the APL can only load/unload parts from the main spindle. Availability may vary by region.

The following charts are for reference only.
These power numbers are based on 240V service, supplied at the required amperage.
Actual results may vary depending on the supplied power and the operating conditions.
Haas spindles will provide these peak power numbers, which equate to 200% spindle load, for three minutes,
150% spindle load (75% of the peak number) for 15 minutes, 100% spindle load (50% of the peak number) continuously.
