SJ6000 Machine Tool Laser Interferometer Calibrator

Zhongtu Instrument SJ6000 Machine Tool Laser Interferometer Calibration System offers a measurement resolution of up to 0.01″ and a system measurement accuracy of ±1″. The WR50 automatic precision rotary table has a repeatability accuracy of 0.2″. It mainly consists of the SJ6000 laser interferometer main unit, angular mirror set, WR50 automatic precision rotary table, and SJ6000 rotary axis measurement software. It features high measurement accuracy, wide measurement range, fast measurement speed, and high resolution even at high speeds. Combined with different optical mirror sets, it enables high-precision measurement of geometric parameters such as linear length, angle, straightness, perpendicularity, parallelism, and flatness. With dynamic measurement software, it can also perform dynamic measurement and performance testing of linear displacement, angle, and straightness, as well as dynamic analysis of displacement, velocity, acceleration, amplitude, and frequency, such as vibration analysis, dynamic characteristic analysis of screw guides, and response characteristic analysis of drive systems.

SJ6000 Machine Tool Laser Interferometer Calibration System is an AC testing system. When the laser beam intensity is affected by environmental changes, its frequency remains unaffected by variations in light intensity and does not alter due to changes in signal levels. As a result, it offers strong anti-interference capability, high precision, and reliable measurement results. It is widely used in high-precision applications such as chip lithography machines, metrology inspection, and cutting-edge scientific research.

Performance Features

1. Easy to Operate and Portable

The SJ6000 laser interferometer, mirror sets, and environmental compensator are compact, aesthetically pleasing, and portable. A complete set of laser interferometer and mirror sets can be stored in a suitcase-like toolbox, with a total weight of approximately 15 kg. Paired with an adjustable-height tripod (packed in a non-woven bag), it can be used for mechanical measurements anytime, anywhere! The laser interferometer and environmental compensator are equipped with ports to connect to a computer via USB, transmitting real-time detection data for computer calibration software analysis. The calibration process is straightforward and easy to master, with no complex programming required.

2. High Accuracy Ensures Dynamic Performance

The helium-neon laser continuously outputs a highly stable frequency laser source. Combined with the environmental compensator, it ensures linear measurement accuracy remains stable at 0.5 ppm. The dynamic data acquisition frequency reaches up to 50 kHz, with a measurement speed of 4 m/sec and a resolution of 1 nm at high speeds. Interferometry ensures confidence in the detection results.

3. High-Quality Technology

Meticulous design, strict manufacturing standards, continuous technical support, and quality assurance are all critical. Support is provided pre-sale, during sale, post-sale, and through a nationwide network.

4. Applicability and Flexibility

The SJ6000 laser interferometer is flexible to set up and widely applicable to various complex machine tools, platforms, and guides. It enables fast and simple measurements, reducing the time required for repeated positioning measurements while providing accurate and intuitive detection data.
