Evamet - Creusot (71)
Evamet, formerly Carbex, is a historical company in Saône-et-Loire. In 1949, tungsten carbide tools were already being manufactured here, behind the walls and under the Eiffel-style riveted metal structure built in 1911, which then housed the Schneider electric station.
Today, Evamet produces carbide inserts as well as wear parts. "We develop our own grades. Two people are in charge of this activity in our metallurgy laboratory, where the nuances are not only elaborated but also tested, describes Benjamin Julliere, manager of the Group. " We make our own mixtures, we grind tungsten powder, we master the granulation and then we carry out the pressing shaping, sintering and grinding ". There is a press shop with its pellet presses on which the cutting inserts are pressed. Carbide blanks are manufactured from lopin pressed into bars in a cold isostatic press, which are then shaped on CNC lathes and milling machines, before being hardened in a HIP (Hot Isostatic Pressing) sintering oven. Then they are either rectified or the raw material is supplied as is.
In the finishing shop, where lapping operations are performed to adjust the thickness of the inserts, the peripheral grinding of the inserts is carried out on 4- and 5-axis robotized NC centers. These high precision grinding machines also allow us to manufacture and grind ceramic and CBN inserts.
A fleet of machines in continuous renewal with recent investments, especially in cutting edge treatment systems for carbide inserts, for a smoother finish and better chip glide.
