General characteristics: 1. High precision, high stability, high repeatability: fully meets the measurement requirements of the test object.
1) The world's leading high-precision linear encoder system and high-precision inductance measurement system;
2) The high-precision grinding rail is made of good material with high wear resistance.
3) High-performance linear motor drive system
2. Intelligent Measurement Software Thanks to the user-friendly software interface, the operator can understand the basic operation of the machine.
3. Measuring Force The measuring force controlled by the voice coil motor drive system can be continuously adjusted from 10 mN to 150 mN, and the resolution of the measuring force is 0.2 mN;
4. Intelligent protection system Once the measuring probe collides with the test object/part holder, or the pulling force of the measuring probe is too great during the scanning process, the machine will stop scanning to protect the measuring probe and the measuring system.
5. Flexible Manual Control The machine is equipped with a joystick, which can be used to position the probe before measurement. The operator can control the measuring probe to move it up and down, left and right quickly without a computer.
