Unless the spindle is thrashed, I'll betcha you can grind a 3" x 3" x 1" block parallel and flat within 0.0005" even if it's pretty worn. For a lot of guys and a lot of jobs, that's plenty good enough. I have the opportunity to acquire a Brown and Sharpe 510 Surface grinder. it is a manual machine as many should know, but I have never owned a ...

ادامه مطلبSurface grinding . Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface.

ادامه مطلبSurface grinding services can also be used on rods, although not to make the outside diameter of a rod round; for that task, OD grinding (also known as cylindrical grinding) is used. However, surface grinding can make the two ends of a rod perfectly perpendicular to the outside diameter. Here, V-blocks are used to position rods for grinding.
