激光校验机器的优点

提高机器的正常运行时间
不管使用哪种机器或运动系统，在开始切削或加工材料或测量部件之前，您都需要知道设备运行是否正常。 您可以了解机器定位性能的每个特性随时间发生变化的详细情形，预测某特定机器何时需要维修并预先建立应急计划。

提告机器性能
通过有针对性的维护和误差补偿，Renishaw的性能测量设备可确实提升机器的性能。

增强对机器或加工能力的了解
使用适合工作要求的机器 — 把工作安排给能够达到公差要求的机器，确保机器适合工作要求并且废品率较低。

证明机器性能
当客户需要对您的机器质量或工艺树立信心时，校准曲线和定期性能评估结果将是的证明。它们能够赋予您宝贵的竞争优势，使您于那些没有进行这些测试的制造商。

符合质量保证规程和标准
ISO 9000系列质量标准要求采用公认的、可溯源的系统和方法对生产和检测设备进行校准、监视和控制。

提供的维护服务
高质量的售后服务不可或缺。在用户现场使用与系统原始制造商在其工厂内使用的相同校准工具进行校准，这是使机器恢复为制造商原始规格的方法。

XL系统组件

XL-80 laser unit

The XL-80 laser produces an extremely stable laser beam, with a wavelength that is traceable back to national and international standards.

• Laser frequency stability  ±0.05 ppm over 1 year and ±0.02 ppm over 1 hour is achieved by dynamic thermal control of the laser tube length to within a few nanometres.
• Linear measurement accuracy  ±0.5 ppm over the whole environmental range ie, from 0 ºC - 40 ºC (32 ºF - 104 ºF) and 650 mbar - 1150 mbar. Readings can be taken at up to 50 kHz, with a maximum linear measurement speed of 4 m/s and a linear resolution of 1 nm; even at maximum speed.
• Integrated USB means there is no requirement for a separate laser-to-PC interface.
• LED status lightsindicate the laser status and signal strength, providing a convenient alternative to the software’s “on-screen” indicators.
• Switchablebetween standard (40 m) and long (80 m) range modes.
• Analogue I/O portallows for analogue signal output and a trigger signal input.
• Warm-up time is less than 6 minutes.
• External, switch mode power supplyensures 90 V - 264 V flexibility in input voltage.

All of the above features make the XL-80 quick and easy to use.

In accordance with (IEC) EN60825-1, Renishaw XL-80 lasers are Class 2 lasers and safety goggles are not required. Always refer to the system manual for safety details before operating the system for the first time.

XC-80 compensator and sensors

The XC-80 compensator is a crucial factor in your XL system’s linear measurement accuracy. Featuring “intelligent sensors” that process the readings at source, the compensator very accurately measures air temperature, air pressure and relative humidity. Changes in these conditions can effect the wavelength of the laser light and the measurement readings taken.

The XC-80 uses the sensor readings to modify the nominal value of the laser wavelength to give a true value, which is then used in calculations to virtually eliminate any measurement errors resulting from these variations.

If you are interested in accuracy you NEED effective wavelength compensation.

Key features of XC-80 include:

• Uniform compensation - The design of the XC-80 and sensors ensures uniform and extremely accurate readings over the full range of environmental operating conditions.
• Frequent sensor updates - This can be done automatically every seven seconds, as indicated by LED status lights on the XC-80 unit.
• Integrated USB- The inetgral USB connection means there is no separate PC interface and no separate power supply (the USB supplies the XC-80 and sensors' power).
• Lightweight - The XC-80 weighs 550 g, and together with the XL-80, weighs just over 3 kg (including connecting cables, XL power supply and sensors).
• Intelligentair and material temperature sensors- The integral microprocessors analyse and process the sensor's output before sending digital temperature values to the XC-80 compensator. This offers more secure measurements and is a key reason why the XC-80 is so compact and also ensures sensors are fully interchangeable without comprimising accuracy.
• Up to three material temperature sensors can also be attached to the XC-80 compensator to allow linear measurements to be normalised to a standard material temperature of 20 °C.
• Versatile sensor cables - The standard 5 m long sensor cables are detachable for easy replacement and can be screwed together for extended lengths on longer machines.

Note:Environmental compensation is NOT required for angular or straightness measurements when using a Renishaw system as these are calculated from differences in two beam paths close together, where the environmental factors self cancel. As rotary axis, flatness and squareness measurements are also based on these measurements they also do not require environmental compensation.

Tripod and stage

Unless you are using a dedicated measurement rig, then you are likely to need a mounting stage (and in most cases a tripod) to adjust the laser’s position relative to the desired measurement axis.

• The XL mounting stage allows for precise angular rotation and translation of the XL-80.  It is designed to be left attached to the laser unit for easy storage and quick set-up.
• A "quick fit/release" mechanism enables rapid and secure fixing to a tripod.  For those applications where tripod mounting is not convenient, e.g. for mounting directly on a machine tool table, the stage and laser can also be mounted on to most standard magnetic bases, using an optional adapter with M8 thread.
• The new Universal tripod has been extensively tested to provide a stable, adjustable base in a compact, lightweight unit.

XL-80所用的测量光学镜组

Renishaw measurement optics enable you to measure linear, pitch, yaw, horizontal and vertical straightness along any axis. Additional optic kits are available to enable measurement of surface flatness and squareness of axis.

The same optics can be used with XL-80 or ML10 systems, ensuring consistency of measurement set-ups and procedures. All measurements are interferometric and therefore use the traceable international standard wavelength of laser light, allowing you to have total confidence in the results.
