Fitting works can be performed by machines or by hand.
In assembly shops these works are mostly performed by using the techniques of filing, scraping and reaming.
Files
All forms of finishing, fine finishing and precision files are used for removing roughnesses and unevennesses, for rounding and chamfering sharp edges and for deburring.
Figures 6 Files
Scrapers
All sorts of scrapers are used for producing exact surfaces for guides, for fitting in parts with exact bearing faces and for producing tightening bearing faces.
Figure 7 Scrapers
Reamers
We use hand reamers with and without angular momentum, readjustable reamers and tap wrenches which are required for reworking or making precision bores.

Matching pieces
For the direct control and assembling we use matching pieces corresponding to the element to be worked.
Figure 9 Matching pieces
Testing means
All types of gauges for tolerance and fit determination and form determination are used, particularly in the series production:
|
- plug limit gauge |
- for bores up to 100 mm |
|
- flat limit gauges |
- for internal dimensions exceeding 100 mm |
|
- spherical-end measuring gauges |
- for internal dimensions exceeding 250 mm |
|
- external limit gauges |
- for external dimensions |

Measuring instruments
In addition to vernier calipers, external micrometers, internal and depth micrometers, as well as dial gauges are used for an exact size determination particularly in the individual production.
Marking devices
Levelling straight-edges, surface plates, colours or paste and devices (to distribute the colour so that surface defects can be recognized) are used.

Special clamping devices
We use various devices and supports which make possible a fast and careful clamping of hard-to-hold parts.
Vice
Vices with flat or Vee-jaws and additional protective jaws of different materials and forms are used for a safe and careful clamping of component parts.
