Sandvik Coromant’s QS Micro quick-change toolholding system is designed specifically for sliding head machines. It can provide enhanced precision, security, repeatability and maximized machine utilization.
The QS Micro toolholding system is designed for small-part machining and sliding head machines. It can cover 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 toolchanges.
The assortment includes rectangular shaft adapters in sizes 10 × 10 mm up to 20 × 20 mm as well as equivalent inch sizes. It also features cutting heads for general turning, parting and grooving, plus 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, which can offer advantages such as higher stability and better chip evacuation.
“One of the main benefits of the QS Micro toolholding system is that it is possible to quickly change cutting heads with high precision, which reduces the machine’s downtime,” says Hampus Jemt, global product manager for small part machining and threading at Sandvik Coromant. “Another benefit is the modularity, which enables the fitting of different types of cutting heads in different adaptors, reducing the need for a large tool inventory.”
According to the company, other benefits include a rigid toolholding mechanism that minimizes vibrations, enhancing precision in sliding head machines without compromising process security. High indexing precision (±3µm) can also enable optimized component quality, accuracy and repeatability across various operations.
Furthermore, all QS Micro shank adapters provide through-coolant functionality, enabling simple coolant connection to the cutting heads, and the precision coolant is delivered directly to the insert.
