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.
Achieving consistent and quality results from the centerless grinding process requires an understanding of the basic fundamentals. Most application problems associated with centerless grinding derive from a misunderstanding of the basics. This article explains why the centerless process works and how to use it most effectively in your shop.
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.
Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
