Hands free tool changes for smarter machining
Using conventional tool management methods, a lathe could run without human input for around four-to-eight hours. After that, the tool would reach the end of its life and a human worker would need to stop what they’re doing to manually switch the tool with a new replacement. With the ATC solution, machines can run for up to 16 hours without an operator worrying about them.
After using ATC technology for several years, Sandvik Coromant has now developed a solution for its customers that enables hands-free tool changes in turning operations. The new ATC system for machine-adapted clamping units (MACU) in turning centers fully automates the tool-changing process, eliminating the need for manual intervention. This leads to higher machine utilisation and improved productivity.
The immediate benefit is the time it saves human workers. Running machines for up to 16 hours — four times longer than before — without the need for operator intervention allows operators to focus on other tasks, rather than being occupied with constant tool wear inspections.
ATC also helps optimise tool wear. When operators manually change tools while juggling multiple other tasks, they often replace tools prematurely, before they’ve reached their full potential. With ATC, tools are changed only when they’re fully worn, maximising tool life and reducing waste. ATC also delivers significant sustainability benefits, including lower energy consumption, enhanced resource efficiency reduced waste and improved overall equipment efficiency. By keeping machines running at optimal levels, ATC minimises idle time and energy waste, increases output with fewer resources and reduces the frequency of breakdowns and downtime.
