Inner and outer diameter detection

Equipment purpose

Used for dimensional inspection of finished deep groove ball bearings

The device includes functions

a) Outer diameter size inspection

b) Inner diameter size inspection

c) Inner and outer circle height detection

technical indicators

The outer diameter size range of machinable bearings is: φ 20~φ 30mm, φ 30~φ 60mm, and φ 60~φ 90mm;

Pen recognition accuracy: 0.1 μ m;

Measurement frame repeatability accuracy: 1 μ m;

Internal hole measurement method: three-point contact probe, needle loading machine, one workstation axial displacement axial measurement of 2 cross-sections, automatic calculation of inner diameter size, taper, etc;

Outer diameter measurement method: three-point contact probe, one workstation axial displacement axial measurement of 2 sections, automatic calculation of outer diameter size, taper, etc;

Height measurement: using single point contact measurement, the measuring pen directly reads the height value of the product;

Work efficiency: 4.0-6.0 seconds/set
