New Larger Sherline & Taig Compatible Headstock

ATC-READY (Automatic Tool Changer) for Mills

---Taig requires our Dovetail Adapter Option---

(Your headstock will come fully assembled. Tormach TTS sold separately)

The Sherline and Taig headstocks are a good little headstock, but it’s a bit too small for some needs. Because of the demand for a more robust headstock with larger bearings; we introduce the Glock Billet Headstock. It has all the mounting features of a stock Sherline headstock to keep it completely compatible with Sherline products. Plus, it has additional mounts for custom machines. The differences are as follows:

• You can now have a more robust 3.5”W x 3.5”T x 3.0”L, that’s a full 1.00” wider and taller (0.50” on each side & 1.00” taller than a stock Sherline headstock, center is still 1.75”)
• Larger 62mm OD bearings for heavier work load and superior wear, so you can use heavier chucks, parts or cutters (stock is only 42mm OD)
• Available in deep groove, angular contact (both in ABEC-5 or ABEC-7) and heavy load taper bearings
• (4) ¼-20 threaded mounting holes on the bottom of the headstock for superior rigidity on custom setups
• The new headstocks will accommodate R8, MT3/chuck adapter, MT3, ER 25, 32, 40, 50 and - 5C with rear drawtube coming soon (it will be slightly larger in size)
• Higher rigidity Using the MT3 or R8 spindle with Tormach Tooling System...this will allow for custom ATC (automatic tool changer) applications or rapid manual changes. A huge variety of cutters and cutter holders. Also, the TTS transfers the tool press to the face of the spindle and the angular walls. This makes it much more rigid than just using the angular inside portion of the spindle. We also recommend a larger Z axis for this.

ATC & Tormach Tooling System (TTS) - (you may order Tormach TTS parts directly from us) The headstock with R8 or MT3 spindle will be required to use TTS. Your new headstock is ATC ready. In other words, you can adapt a pneumatic or electric linear actuator for this. The design is up to you. Please note: while the R8 will afford you more options for R8 specific tooling, the MT3 spindle places the tooling closer to the bearings and will allow for more Z axis movement. This is because the nose that sticks out from the bearings is shorter by about a ½”. It is therefore more rigid and allows for more Z movement.

TTS will also allow you to program tool heights into your control software, such as Mach3 or Mach4.

Recommendations:

• While not necessary, we do recommend using at least a 550 watt motor for this. The bearings are much more heavy duty. If you choose to use a stock Sherline motor, it will work, however you will need a longer belt (it will directly mount, holes are in the same place and size as on a stock Sherline headstock).
• Taig motors will not work effectively with this headstock. The motor and belts are too weak. While Taig machine bodies are very well made, the motor and belts won't be enough.
• Pulley - Many opt for a timing pulley set. You may also adapt a stock Sherline pulley.
• We offer both V groove & timing pulley taper lock sets and adapted Sherline pulleys.

Please note: Because of heavy demands, please expect about a 4 week build time.
