Video: What is Double Disc Grinding?
This footage shows grinding of opposite surfaces at the same time.
Double disc grinding makes it possible to grind opposite surfaces of the part at the same time, potentially reducing overall grinding cycle time. This style of grinding also makes it much easier for a shop to maintain tight tolerances on flatness or parallelism between surfaces, as this footage from TCI Precision Metals shows.
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.
Wire EDM units that swivel a horizontally guided electrode wire in a CNC-controlled E axis give this shop the workpiece clearance and flexibility to produce complex, high-precision PCD-tipped cutting tools.
