Machining day

Held jointly by Sandvik Materials Technology and Sandvik Coromant at the company’s Halesowen facility, it included presentations and machining demonstrations on how to achieve the best productivity.

Sandvik’s technical marketing manager for primary products, Marcus Hillbom, talked in detail about the material implications on cost effective machining of stainless steels and the main factors affecting machinability. This included a series of guidelines on material, set-up, fixing, insert choice and use of coolant in order to obtain the best chip break and subsequent tool life.

Delivering increased productivity and competitiveness was the subject of Sandvik Coromant product & application manager Paul Williams’s presentation. It showed how working in close partnership with customers and by sharing knowledge it was possible to generate value. He explained that by driving up productivity it could be possible to deliver more machining in the same production time by increased throughput for the same fixed costs. He also discussed the basis of green light production, meaning actual machining times, and ways of increasing this by reducing cycle times.
 
There followed live machining demonstrations on turning and boring, drilling, milling and taping and an introduction to the latest CAM programming techniques for small diameter solid carbide end mills for the production of  deep pockets at high metal removal rates.
 
After the presentations, customers had the opportunity to tour the extensive material warehouse and view the comprehensive range of additional services offered by Sandvik Materials Technology, including cutting to size, packaging, colour coding, marking, stencilling, vibro-etching and electro etching, along with mill support operations, project management facilities and full material documentation for complete traceability.
