Runout (jump precision), thermal elongation, inclination, vibration and other indicators are important performance indicators of motors, spindles, high precision machine tool, and other rotary equipment. This index is also one of the important factors affecting the product’s quality and machine’s life. Previously, people often used contact lever meters or simple measuring tools to detect its runout and related indicators at low speed. However, with the development of science and technology, the precision requirements of rotary equipment are getting higher and higher, and some have reached the nanometer level, in addition, more and more industries and equipment need the relevant runout, thermal deformation and other parameters in the state of high-speed operation. For these middle and high end measurement requirements, the traditional low-speed, contact measurement can not meet the requirements.
The advent of a new high-speed non-contact rotary error analyzer is a good solution to these high-end detection needs. The rotation error analyzer is generally composed of high-precision test rod, high-precision non-contact capacitance sensor, high-precision temperature sensor, high-precision sensor mounting frame, signal receiving and processing host, and analysis software. The testing equipment has many advantages that cannot be achieved by traditional measurement means, including but not limited to the following parts:
1. Due to bearing clearance, rigidity and other reasons, the runout and vibration equivalent of the low-speed state are different from the relevant indicators of the real high-speed operation state. What users should really care about is precisely the indicators under high-speed operation. The sensor of the rotation error analyzer is not in contact with the measured object, there is no problem of friction and wear, and it can detect the relative accuracy of the rotating equipment in the high-speed operation state.
2, the capacitive sensor, test rod, support frame, and signal processing device used in the return error analyzer are specially high-precision products, ensuring the accuracy and resolution of the equipment detection is very high, and the current resolution can reach 5-10nm (nanometer) or even higher. The resolution of the traditional lever meter is only about 1 micron.
3, the rotation error analyzer in each rotation of the workpiece, it measures a value, and then dozens or even hundreds of times, until tens of thousands of measurements of the value of the average display. This ensures that the measured value is as close to the actual value as possible. In the traditional contact measurement, the value is often measured several times, and the error (measurement accuracy) between the measured value and the actual value is often large.
4, rotation error analyzer professional analyzer software, can separate a variety of errors. The same is the radial runout error, the software can separate out the non-synchronous error (affecting the shape of the machining), the asynchronous error (affecting the machining surface roughness), the fixed radial error (suitable for the single direction of the lathe stress equipment), the rotary radial error (suitable for the grinding machine, milling machine and other rotation direction stress error). At the same time, the software also has the FFT spectrum analyzer function, which can measure the vibration size and change of equipment at different frequencies, helping users analyze the cause of vibration and accuracy.
5, the rotation error analyzer has the temperature detection function, can detect the temperature change of the equipment for a long time. It can also detect the change of thermal deformation, inclination and other indicators with temperature.

In view of these superior performance, the rotation error analyzer has been increasingly popular with high-end customers
Loved. The products are widely used in high-precision spindle, high-speed motor, high-precision machine tool, high-precision test bench and other high-precision rotary equipment. The types of factories include the research and development, production, use, maintenance and inspection units of related products.
At present, there are few companies in the world that can provide high-precision rotation error analyzer. Before, the industry is more familiar with a American brand. But the price of imported products is getting higher and higher, which is not acceptable to ordinary companies. At the same time, foreign brand products strictly restrict the sales of some high-tech enterprises and special industries in our country. In order to fill this gap in China, we have gone through painstaking scientific research and multi-party testing and comparison, and developed in addition to our own brand of IRED rotation error analyzer. In addition, the test results of our analyzer have been compared with the refined test results of the products for many times, and the results show that our products have been able to fully provide imported products.
