JD22

Quantity:
  • Digital Vertical Metroscope
  • Digital Vertical Metroscope
  • JD22 adopts Abbe's principle and optical grating sensor system. It is guided by six C-grade bearings and two super-C grade bearings, with high linearity and high accuracy. Mainly used to measure gauge block、cylindrical gauge block, thickness of template, middle diameter of external screw thread, diameter of cylinder and spherical shaped workpieces etc.

Digital Vertical Metroscope

PURPOSE 
1. It adopts the advanced digital amplitude optical grating sensor system. 
2. It can measure the activity of axle. It is guided by six C-grade axle bearings and two super-C grade axle bearings. It has high linearity. 
3. It's design accord with Abbe's principle and has a high accuracy. 
The usage: 
It adopt advanced digital readout system, can nice measure external size of various kinds of work piece. It's typical measuring objective include: Two parallel (such as ), cylinder, section, sphere, spherical surface, measure external Pitch diameter of external thread by three-pin technique.
