Fitting
The fitting gathers the Action S aiming perfecting machine elements (to remove the small defects) and at assembling them with an aim of manufacturing a Organe functional Mécanique.
In spite of the apparent simplicity of these work, those induce a required and snuffed trade comprising various specialities.
Corrective fitting consists in improving the parts with an aim of perfecting the final geometry and dimensions. The fitting of finishing consists in improving the parts with an aim of perfecting the visual aspect or the surface quality.
The fitters " correcteurs" generally bear the name of their tools except some cases. One finds as follows:
them Tirpos of the tool Tirepoint (three-square file where isosceles). These fitters are specialized in the manual resumption of the dovetails, they must control trigonometrical calculation, bases dimensions on measuring rods which they use; them ébavureurs whose name gives the function; them Chanfreineurs, charged to carry out the chamfers on parts; them Teaslers, which uses a Grattoir and whose trade consists in perfecting the plans of support (precision 0,005 mm). These fitters use the " Prussian blue like revealing to replace the Blood ; them Rifleurs, also named Fitters moulists and whose tool of predilection is the Rifloir; them Gunners length whose role consists in finishing the songs of part (left narrow) in Tiré length; them Cruisers whose role consists in finishing surfaces of part in cross Traits.
The fitters " paracheveurs" are fewer, have finds:
it Engraver, - the arasor.
A specialist in the fitting is a Ajusteur.
