Sandvik Coromant Connected Driven Tool Holder Maximises Machine Utilisation

Sandvik Coromant is set to boost the utilisation of turning machines and turret-based multi-task machine tools fitted with driven tool holders. Part of the CoroPlus digital machining offer, the company’s Coromant Capto DTH Plus solution minimises costly downtime due to breakages by alerting an operator to the need to service an individual driven tool holder. This enables manufacturers to achieve maximum machine tool productivity and output through predictive maintenance as well as offering fast tool changes in applications using driven tools.

Sandvik Coromant is introducing the new product to solve a common problem for many manufacturers—knowing the optimum time to service their equipment while avoiding the likelihood of tool holder breakage. Outside a planned maintenance schedule, an operator could be running a tool holder in an environment that risks costly damage to equipment, resulting in machining failures and unplanned stops in production.

Developed to complement the Coromant Capto quick-change tooling concept from Sandvik Coromant, the new driven tool holder solution uses sensors to gather data and transmits them via Bluetooth, making predictive maintenance of the holder possible. Thanks to quick-change functionality, the time an operator needs to spend on measuring, set-up, and tool change is kept to a minimum. Also, because the driven tool holders are equipped with Coromant Capto coupling, the solution enables operators to make use of an extensive range of high-performance cutting tools.

The software application included in the new offer provides operators with real-time information – such as the vibration level of the holder—making live monitoring of the spindle possible, while also monitoring the temperature within the tool holder. Other data delivered through the sensors include RPM and direction of rotation, minimising the chances of exceeding the driven tool holder’s limits, and current and historical information about a particular tool. Also provided is data on the location of a driven tool holder, including the specific factory, machine name, turret and station number.
