WENTAO LMI Series Non-Contact Laser Tool Setter for CNC Machines

### WENTAO LMI Series Non-Contact Laser Tool Setter

The WENTAO LMI Series (LMI-54 / LMI-94 / LMI-164) is a premium, high-precision non-contact laser tool measurement and breakage detection system[cite: 5]. Specially engineered to operate seamlessly inside the harsh environments of CNC machine tools, this series enables micron-level, non-contact measurement of tool length and diameter for both rotating and non-rotating cutting tools[cite: 5]. By automating tool setup and executing rapid tool breakage monitoring, it eliminates manual operational errors, minimizes workpiece scrap rates, and significantly maximizes manufacturing productivity[cite: 5].

### Key Features & Advantages

* Ultra-Small Micro-Tool Capability: Advanced optical design allows the system to reliably detect and measure exceptionally micro-sized tools, with a minimum measurable tool diameter down to 0.03 mm[cite: 5].

* High-Speed Broken Tool Detection: Performs ultra-fast, real-time in-process monitoring for single-edge tool breakage and run-out error detection during high-speed positioning[cite: 5].

* Dynamic Run-Out Monitoring: Measures the dynamic run-out of rotating spindles using advanced non-contact simulation methods, preventing machining defects before they happen[cite: 5].

* Spindle Thermal Expansion Compensation: Provides accurate real-time compensation data for machine tool spindle thermal expansion, ensuring absolute dimensional accuracy across long production cycles[cite: 5].

* IP68 Extreme Enclosure Defense: Rated with top-tier IP68 industrial protection (operational under continuous air supply status)[cite: 5]. The robust housing completely shields the laser optics against persistent cutting fluids, heavy coolant mist, and sharp metallic debris[cite: 5].

* Certified Class II Laser Safety: Utilizes a highly stable and safe Class II laser system operating at a wavelength range of 630–700 nm with a safe power output of < 1mW[cite: 5].
