(Hoffman Estates, IL ) – Renishaw introduces the new, second-generation TRS2 broken tool detection system. Industry-first “one box” design combines the laser source and detection electronics in a single compact unit just 83mm high x 38mm wide x 73mm deep (3.27″ x 1.50″ x 2.87″), enabling easy mounting outside the work zone, safe from collision. The TRS2 can detect a whole range of solid center tools, including drills, taps, reamers, slot drills, standard and ball nose end mills, and now even gun drills. Detection typically takes only a second. The system can process tools as small as 0.2 mm, while screening out chip and coolant mis-readings. The versatile TRS2 can be easily fitted to everything from mini drilling systems for electronics boards to large machining centers.
The laser system offers wide detection range – 0.3m to 2.0m/13″ to 80″ – while innovative
Toolwise™ electronics technology reliably distinguishes good tools from broken tools without mis-readings caused by coolant and chips. Unique to Renishaw, the Toolwise technology analyzes reflected light patterns from the rotating tool as it enters the beam, rejecting random light patterns created by coolant or chips. Tool edges generate a regular light pattern as the tool spins, while chips and coolant give random reflections. A repeating pattern represents a tool present and whole. A non-repeating pattern indicates a tool broken.
The advanced electronics can detect and process reflections off both bright and dark tools. New on the TRS2, monitoring can be provided at three different tool rotation speeds – 5000 rpm, 1000 rpm and 200 rpm – to cover a wide range of applications and tooling. Used for high-speed tools, 5000 rpm is the default speed and gives the shortest cycle time. Intermediate 1000 rpm can be used for tools rated for less than 5000 rpm, particularly large, heavier tools. The slowest speed, 200 rpm is intended for gun drills.
The TRS2 can be mounted to any rigid surface of the machine. Positioning of the TRS2 relative to the tool is not critical and does not require accurate alignment with the machine's axes.
The tool recognition process is fast, usually taking about one second. A flexible setup process allows a user-defined broken tool detection point to be established within the machine's envelope. Detection is performed when a rotating tool reaches this point.
