TRS2

The Renishaw TRS2 is a laser-based, non-contact tool breakage detection system designed specifically for solid tools (such as drills, taps, and end mills). Its key advantages include ultra-high speed, non-contact operation, resistance to interference, and the ability to detect even the smallest tools, making it an essential safety feature for automated production lines and high-speed machining centers.

Core Positioning and Design 
Core Application: Tool breakage/missing detection (not length/diameter measurement), preventing machining without a tool or with a broken tool 
Detection Principle: ToolWise™ laser reflection analysis technology (not simple beam interruption), resistant to coolant and chip interference (Renishaw) 
Structure: Compact, integrated transmitter-receiver unit (83×38×73 mm), single-housings integrating laser transmission, reception, and signal processing 
Installation: Can be mounted at any angle on the machine tool table, column, or outside the guard, without occupying the machining area, preventing collisions 
Signal: Wired connection (5-core shielded cable), SSR solid-state relay output, stable and reliable 
Protection: Industrial-grade sealing, resistant to coolant, dust, and vibration 
Technical Specifications

Core Features and Applications

Tool Breakage/Missing Detection

Rapid inspection after tool change or before machining: Verifies tool presence and checks for breakage

Detects micro-tools as small as 0.2 mm, covering precision machining applications

Immediate alarm, machine shutdown, or automatic switching to a spare tool upon tool breakage, eliminating batch scrap

High-Speed Non-Contact Detection

Detection takes only 1 second, adding virtually no cycle time

Non-contact operation prevents tool damage, making it particularly suitable for brittle tools such as carbide and ceramic

High resistance to interference

ToolWise™ technology analyzes the reflected light spectrum of rotating tools, automatically filtering out interference from coolant and chips to prevent false readings

Supports inspection of internally cooled tools (requires brief suspension of coolant)

Typical Application Scenarios

Vertical/horizontal machining centers, gantry machining centers, and multi-tasking machines

High-volume, highly automated production lines for automotive parts, 3C electronics, medical devices, precision molds, and more

Processing protection for breakage-prone tools such as micro drills, small-diameter taps, and deep-hole drills

Core Advantages (Compared to Contact-Type Tool Setters)

Non-contact and non-destructive: No contact with the tool, eliminating wear and indentations to protect precision cutting tools

Ultra-high-speed detection: Completed in 1 second, far faster than contact-type systems (3–5 seconds), boosting production line efficiency

Extremely Small Tool Detection: Capable of measuring down to 0.2 mm—a feat difficult for contact-type systems

High Interference Resistance: Unaffected by coolant and chips, ensuring stable and reliable performance in shop floor environments

Flexible Installation: Mountable at any angle or externally, without occupying machining space or posing collision risks

Simple Integration: Provides macro programs compatible with all major CNC systems, eliminating the need for complex software
