About TTS
About the Tormach Tooling System®
Genuine Tormach Tooling System® toolholders and accessories are the benchmark in affordable quick-change tooling for small milling machines employing R8 or MT3 spindle tapers. The dual-contact geometry of TTS ensures Z-height repeatability and increases tool rigidity over traditional collet and toolholding systems.
TTS is compatible with PCNC mills, as well as most Bridgeport mills and clones. Â Each TTS product has been exclusively engineered and designed by Tormach and is subject to a comprehensive QA audit at the factory. Look for the Genuine Tormach TTS label to ensure quality and avoid careless imitations.
How does TTS work? The TTS shoulder is undercut so it contacts the spindle itself, not the end of the collet. As the drawbar is tightened the collet will simultaneously squeeze the shank and move upward into the spindle taper. It is this simultaneous action, grasping while moving up, that pulls the toolholder tightly against the spindle face. The high pressure contact between the shoulder of the toolholder and the spindle is the equivalent of a zero tolerance fit; the vertical location of the tool is exact. The initial placement, created by simply sliding the toolholder up until it stops, is normally within a few thousandths of an inch. The final location, after tightening the collet, is exact, highly repeatable, and not affected by the variable tension of the drawbar or wear on the collet. And what’s more, the zero tolerance fit in combination with the wide base of the shoulder provides a significant increase in toolholder rigidity.
Benefits for both CNC and Manual Mills
- DUAL CONTACT GEOMETRY The Dual Contact Geometry on TTS offers technical advantages normally only seen on high end machining spindles (HSK, BIG-PLUS®, and others)*.  TTS tool holders reference both the spindle taper and the spindle face. The unique shape provides a wider base, giving the tool holder a more rigid connection to the machine spindle.
*HSK is a European standard, defined by DIN69893. BIG-PLUS is a registered trademark of Big Kaiser.
- QUICK CHANGE PRECISION Simply loosen the drawbar, slide out the current tool holder, then slip in the next and retighten. The unique geometry of the TTS tool holder ensures that, as the drawbar is tightened, the tool holder moves into an exact Z height.
- REDUCED CLEARANCE The clearance required to remove a TTS holder is only 1.375” – about 70% less than that required by standard R8 tooling. This reduced clearance is particularly important on machines with limited quill travel. A simple tool change on an R8 toolholder can require the operator to move the table to one side, lower the table, or raise the head, all of which greatly impacts the time for tool change and runs the risk of losing the X, Y, or Z position reference.
- OFFLINE TOOL MEASUREMENT Measuring the tools before you mount them on the machine is easier and quicker than tool touch off on the machine. TTS geometry makes off line measurement easy and accurate.
- AFFORDABILITY The high cost of tooling was considered one of the barriers to truly affordable CNC. TTS has changed that. TTS is compatible with the PCNC, or any small CNC using an R8 or MT3 taper and allows you to make what you need easier and quicker without breaking your budget.
- EXPANSIVE OPTIONS The complete TTS line includes toolholders, tapping heads, electronic touch probes, measurement tools, and modular cutting heads – everything you need to get the job done and then some.
