Sandvik Coromant’s QS Micro quick-change toolholding system is developed specifically for small part machining and sliding head machines. It is designed to provide precision, security and repeatability, as well as maximized machine utilization.

The QS Micro toolholding system is designed for small part machining and sliding head machines. It covers the majority of industry segments, such as general engineering, automotive, aerospace and medical. With an extensive range of cutting heads and shank adapters, the system offers a multitude of configurations and quick tool changes.

The assortment includes rectangular shaft adapters in sizes 10 × 10 mm up to 20 × 20 mm, and equivalent inch sizes. It also features cutting heads for general turning, parting, grooving and threading in the Sandvik Coromant families CoroTurn 107, CoroCut 2, CoroCut XS and CoroThread 266. The CoroTurn 107 and CoroCut XS families provide cutting heads designed for Y-axis machining, providing higher stability and better chip evacuation.

The system also features a rigid holding mechanism that minimizes vibrations, enabling precision and process security in sliding head machines. High indexing precision (±3µm) also provides component quality, exceptional accuracy and repeatability across various operations.

Additionally, all QS Micro shank adapters provide through-coolant functionality, enabling easy coolant connection to the cutting heads, and the precision coolant is delivered directly to the insert. Combining quick and easy tool changes with a high degree of modularity, QS Micro is well suited for small-part machining operations.
