1. Once Scanning for both Profile and Roughness
2. High precision, high stability, high repeatability:
2. Intelligent measurement software
Thanks to friendly software interface, the operator can grasp the basic operation of the machine.
4. 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.
5. Flexible manual control
The machine is equipped with a portable 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.
