wire drilling

Wire drilling:



SFAM is a leader in metal wire forming. Our company deals with all drilled metal wire parts on straight, 2D or 3D wires from the conception to the production.


We are wired to your ideas!


Drilling, a simple machining operation is very often requested in addition to metal wire forming.
Indeed, a hole in a part can allow a travel stop, to put a splined stop pin or to weld a fine wire to another bigger one.
Several drillings can allow a precise adjustment of an interval or of the height between 2 elements.
Our know-how and high technology machinery makes it possible to bend and drill metal wire in different diameters ranging from Ø 0.2mm to 18 mm.
SFAM manufactures to your requirements convex, bended, folded, profiled wire.

Drilling processes:

The drilling machining operation (with a drill) is one of the most used ones in the manufacturing of mechanical parts. Around 25% of the machining operations are drilling for general mechanics.
We talk about micro-drilling for diameters under 5 mm, whereas for holes with a diameter over 20 mm, we talk about macro-machining.
Drilling must be considered as a roughing operation, and therefore requires a reaming operation to obtain an exact diametric dimension.
Nevertheless, major advances in the conception of drills have permitted to obtain holes directly with an IT9 tolerance. This being a sufficient quality for a large majority of applications.



Tip: The machining time is constant regarding the diameter of the hole.
