Emuge Corp.’s series of toolholders have variable exchangeable transfer elements and length adjustment screws. Designed for machines with synchronous spindles, the Softsynchro HD and MQL modular system makes it possible for the same toolholder body to be used for minimal quantity lubricant (MQL) or HSK coolant applications.
The modular toolholder can also be supplied with a spring-loaded tube, the preferred method in MQL applications. The same style adjusting screw can also be added to the HD unit in the high-pressure SSY holders. Adjustable coolant tubes are added based on the tap size and style. Users can also order the HSK tube based on a one-channel or two-channel system or HSK-C connection. SSY modular tools can also be custom-built from standard components, depending on the tap size and application.
The modular system also employs a Heli coil mechanism designed to reduce the force that occurs when tightening the collet nut. When tightening the collet nut with the tap fixed against the adjusting screw, there typically is movement that can damage the tap or adjusting screw. The axial movement of the collet can be 0.08 to 0.3, with forces of 800 N to 5,000 N. The Heli coil mechanism compensates for this axial movement, preventing unwanted displacement and potential damage to the tap or MQL adjusting screw. The modular bodies are available in sizes KSN1 ER20 and KSN3 ER32.

This system allows shops to quickly transform the standard external-coolant live tooling heads on their turning machine turrets into those with through-tool-coolant capability.
