Grinder Simplifies Automotive Engine Part Production
IMTS 2018: Meccanica Nova’s Novamatic 2G internal grinding machine grinds multiple bores of an automotive engine component in one work part clamping.
Meccanica Nova’s Novamatic 2G internal grinding machine grinds multiple bores of an automotive engine component in one part clamping. An internally-mounted FANUC robot loads and unloads workpieces.
The company’s ID grinders are flexible, agile, high-production grinding machines with various workholding packages and wheel dressing options for parts ranging from 5 to 420 mm. The grinders are said to speed setups and change-overs, simplify maintenance, reduce cycle times and improve throughput.
Real-time-responding CNC brings new possibilities to difficult machining applications.
It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.
Roughing and finishing on a single machine, using a single setup, has appeal for most shops. The advantages in time savings and accuracy are obvious. Eliminating the transport of workpieces between machines, as well as the setup for those secondary operations, is a boon for throughput. Critical features that need to maintain dimensional relationships can be much more reliably produced if machined complete in one clamping.
