Screw connections play an important role in the cost-intensive and safety-relevant components used in mechanical engineering. The required internal threads are usually manufactured at the end of the production process and their production is technically demanding. If the necessary thread quality is not achieved or a threading tool breaks, this can lead to scrap or costly production interruptions. Coatings for threading tools from the Oerlikon Balzers brand ensure high process reliability, increase tool life and enable shorter cycle times thanks to their surface properties exactly designed for these applications.
In metalworking, one thing holds true: screws hold the world together. So a variety of types of threads can be found in almost all machines and units, turbines and engine blocks, gearboxes and even in everyday objects such as mobile phones. Many factors have to interact in their production, and in addition to tool parameters such as the substrate, geometry and design of the cutting edge, the coating plays an essential role.
