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.
Understanding grinding wheel fundamentals will help you find the right wheel for the job.
In vertical grinding, the workpiece is held upright in a rotary chuck with the grinding spindle overhead. This configuration can improve roundness, facilitate single-setup processing and prolong the life of the machine. Loading and unloading may gets easier, too. Workpieces with relatively large diameters and short lengths benefit the most from vertical grinding.
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.
