Fundamentals of Double Disk Grinding - Metal Cutting ...

Both methods use abrasive particles to remove material from workpiece surfaces. But where double disk grinding use fixed abrasives, bonded to the dual wheels, flat lapping uses loose abrasive powders suspended in a freely moving liquid (slurry). In addition, the lapping process itself is generally done at low speeds.
