Silent Tools™ Plus by Sandvik Coromant
Already a technological innovation in its own right, Silent Tools™ by Sandvik Coromant is a family of tool holders for turning, milling, and boring designed to minimize vibrations through a passive mechanical damper inside the tool body. Machining at long overhangs cannot be done effectively without damped tooling. This damping in the tools not only makes long overhang machining possible, it also provides substantial productivity increases and excellent surface quality improvements. Taking it one step further, Sandvik Coromant introduced Silent Tools Plus. Part of the CoroPlus® platform of connected solutions, Silent Tools Plus is a sensor-based version which provides constant monitoring of tool deflection, cutting forces/tool load and temperature in real time for even more process control and security for internal turning of long overhangs. With Silent Tools Plus chatter can be detected instantly and avoided.
The main benefit of Silent Tools Plus is that it combines the anti-vibration capabilities of the original tooling with valuable insight of the machining process for improved decision making. With Silent Tools Plus, the operator has the ability to know exactly what is going on deep inside a bore feature in an enclosed machine through a user-friendly dashboard. Using Bluetooth technology, data is transmitted from sensors near the damper mechanism and cutting tip to the dashboard. This previously unavailable insight into the cutting process and real-time feedback allows the operator to determine the part quality while in cut, reducing the need to scrap a component. Indicators on the dashboard include surface quality and vibration, damping system temperature, battery life status, cut recording and trend graphics. The center height setting functionality displays the level of the cutting edge. This way, operators can quickly and easily set the center height of the insert to the right level. The result of this is better machining performance and longer insert tool life.
Implementation of the Silent Tools Plus boring bar is quick and easy with minimal machine downtime. Because of the sensors and functionality of setting to center, it actually takes less time to properly mount the bar in the machine than what a standard boring bar takes to install. The Silent Tools Plus vibration indicator will pick up issues during machining at an early stage to help customers prevent chip jamming. The quick-change interface between adapter and cutting head allows for easy handling and optimized machine utilization. It is designed to enable quick and accurate cutting head changes.
Silent Tools Plus is also integrated with CoroPlus® ToolGuide which allows operators to find the cutting tool for their specific task and get instant cutting data recommendations for their operation. Silent Tools Plus is available in cylindrical shank damped boring bars in 10xD Length-to-Diameter ratio overhang solutions in diameters 60 mm, 80 mm, 100 mm, 2.5 in, 3.0 in, and 4.0 in. It can be a stand-alone system so if the machine operator encounters vibration, he or she can adjust the machine control to see the results in real time.
