Machining with carbon power
The future is lead-free — at least as far as brass and copper materials are concerned. This is leading to completely different material properties and behavior during machining. The automotive industry, among others, is noticing the effects. In their search for new solutions, manufacturers are being supported by innovative companies such as Werkö, a German manufacturer of precision cutting tools, and Oerlikon Balzers.
It all began in 2013, when a new EU drinking water regulation limited the lead content in drinking water to 10 micrograms per liter. Manufacturers had to use lead-free brass in the production of sanitation products to comply with the ecological rule. As a result, one of those manufacturers, a Werkö customer, saw a dramatic increase in tool consumption when producing turned parts.
