KELIBRON One caliper, three kinds of size
One caliper, three kinds of size: a 83-second reenactment recorded in the KELIBRON 3D lab, with English captions. The steps below are the captions in order, and you can do the same measurement yourself in the lab.
What happens in the video
- 0:00 One caliper, three kinds of size
- 0:05 Outside diameter: outside jaws deep and square.
- 0:12 Close gently until both faces just touch - never force it.
- 0:20 Read while the jaws are still on the part, then compare with the drawing.
- 0:26 The bore: switch to the inside jaws, close them and slip them in.
- 0:32 Across the centre: rock gently across and take the maximum.
- 0:37 Open gently until both faces touch the bore wall.
- 0:43 Bore reading, compared with the drawing.
- 0:49 Depth: switch to the blind-hole part, beam face flat on the mouth first.
- 0:55 Beam face on the part face, depth rod over the centre.
- 1:00 Push the rod gently to the bottom, just touching.
- 1:06 Depth reading, compared with the drawing.
- 1:12 One caliper: outside jaws, inside jaws, depth rod - each reading compared with the drawing.
In the course
- Caliper fundamentals · Measuring common parts — Measure shafts, bores, flanges and depths on real-sized parts.
- Part inspection in practice · Shafts, bushings and flanges — Measure turned parts and judge them against the drawing.
