Cylindrical plunge grinding experiments were carried out to compare the performance of non-grooved and grooved vitrified grinding wheels. The grooved wheels featured high-angle helical grooves with a 50% groove factor. Grinding forces, spindle power, workpiece roundness, and workpiece surface roughness were measured for five different infeed rates. It was observed that, for the …

Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.

High-production systems began to use intermittently dressed vitrified superabrasive wheels in a creep-feed mode. It was, however, necessary for the application to be high production, or at least have a common form, because the cost of frequently redressing a different form on a vitrified CBN wheel, versus an aluminum oxide wheel, is prohibitive.

"A great example of this is taking a simple aluminum oxide application and trying to move it over to a ceramic grain or even a superabrasive wheel. Unless you have a relatively new machine that's designed for high-performance grinding, you're probably going to have a poor outcome." The problem is one of rigidity, Finch explains.

Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
