AVAILABLE ON THESE MACHINES

Our finishing sub-spindle for ST-10 through ST-28 turning centers – including Y-axis models – will not only make you more productive, 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.

Sub-Spindle Programming

Sub-Spindle programming is made simple by the Haas control. Forget about having to program the Z-axis in the positive direction. Simply program the Sub-Spindle operations the same way you would for the Main Spindle, insert G14 (Secondary Spindle Swap) at the Sub-Spindle Tool Call in the program, and the control does everything for you – from turning on the spindle in the correct direction, to opening and closing the chuck, to turning on the coolant, and more.

The Main and Sub-Spindle can fully synchronize, so you can pass-off a part with the chucks turning. The Sub-Spindle also is capable of phasing (orientation), so you can grip parts with odd shapes.

A dedicated active G-code display on the control lets you know the status of both spindles at all times.

Sub-Spindle Included Parts Ejector

A very high-volume production setup common with sub-spindle lathes involves a bar feeder and a parts catcher. This trio of options allows for extended periods of unattended parts machining.

This is why we include a Parts Ejector with every Sub-Spindle Option. The Parts Ejector inserts directly into the bore of the drawbar, and provides a very simple way to eject a finished part into the parts catcher chute, for continual machine operation without opening the door. The ejector features a removable end piece (push plug) that can be customized to fit your application.
