US7083496B2 - Gear grinding machine - Google Patents

As grinding proceeds, the threaded grinding wheel wears, and its sharpness decreases. Thus, after the threaded grinding wheel has ground many gears continuously, the worn-out threaded grinding wheel needs to be dressed by a dressing device to regenerate a sharp cutting edge. Some gear grinding machines are equipped with dressing devices.

Choosing the proper CBN grit size | Cutting Tool Engineering

Apr 01, 2013· After break-in, users hit the semisteady-state regime, where the wheel is sharp and cuts well, grinding power is low and surface finish is satisfactory. As grinding proceeds, the power drops slowly as the grits sharpen and fall out, and surface finish gradually worsens. Eventually, the finish approaches the roughness limit and you have to dress.

The Three Stages of Grinding and Polishing Concrete ...

Grinding: exposing aggregate Exposing aggregate cast into the concrete requires very aggressive diamond tooling. Metal-bond cup wheels are the fastest for exposing aggregates but leave the roughest surface. Cup wheels are rigid all-metal discs that have thick, diamond-impregnated metal segments mounted along the outer edge of the disc's face.

Which Grinding Wheel Should I Choose? | Norton

Nov 21, 2018· A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.
