Decreasing of roughness
The profile of drawing punches, when they are ready, are then buffed using diamond compound to reduce the roughness to the minimum and giving them their classical brightness aspect mirror-like.
Drawing punches produced by F.C.M. Utensili are principally used to the formation of the rib present on metal packaging lids.
The material used for their production is steel for tools that ensures a good resistance to wearing and at the same time a good price. When a big loti s required, it is realized with integral tungsten carbide.
The profiles obtained are later verified by the use of a tridimensional measure machine,
DEA Global by Hexagon Metrology, to guarantee their correct measurement since the tolerated variance are of few micron.
