§≡≡≡≡    Features   ≡≡≡≡

1. High precision, high stability, high repeatability: fully meet the measurement requirements of test object.
  1)The world's leading high-precision linear encoder system and high-precision inductance measurement system;
  2)High-precision grinding rail is made of good material with high wear resistance.
  3)High-performance linear motor driving system
2. Intelligent measurement software
Thanks to friendly software interface, the operator can grasp the basic operation of the machine.
3. Can measure multiple parameters
Automated evaluation of roughness including Ra, Rz, Rp, Rt, etc.
4. Measuring force
Measuring force controlled by voice coil motor driving system is continuously adjustable from 10mN to 150mN, and the resolution of measuring force is 0.2mN;
5. Intelligent protection system
Once the measuring probe collides with test object / workholder, or tensile force to measuring probe is too large during scanning process, the machine will stop scanning in order to protect measuring probe and measuring system.
6. 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 up and down, left and right quickly without the computer.
