COST RELATIONSHIPS：
The following cost analysis takes account of labor cost, machine cost and grinding wheels cost. Workpiece quality and redress life are related through the number of parts ground before roughness or roundness tolerance is exceeded.
GRINDING WHEELS COST:
This is an easy question to understand for everyone, generally speaking, the superabrasives wheels are much more expensive than the conventional grinding wheels.
LABOR COST:
Along with the economic development, the labor cost will be higher and higher, if you want to cut down the labor cost, you must promote the production efficiency. On this condition, the superabrasives grinding wheels will be good, it can supply much higher grinding efficiency compared with the conventional grinding wheels.
MACHINE COST:
With the economic development, people purchase high grade machine, so the machine cost become higher than before, if you want to cut down the production cost, you must produce more workpieces in a short time, namely improving the produce efficiency. On this condition, the superabrasives grinding wheels will be a good choice.
WORKPIECE QUALITY:
The workpiece quality criteria are always the accuracy, brightness, damage or not on the workpiece surface. For the superabrasives grinding wheels are good at the wear resistance, the superabrasives grinding wheels always can supply better accuracy because of the feature of diamond & CBN grain. It is not easy to hurt the workpiece compared with conventional grinding wheels, also, the superabrasives grinding wheels can give good brightness.
GRINDING AMOUNT:
For the surface and cylindrical grinding, the superabrasives grinding wheels can’t supply the obvious advantage on the grinding amount, if the conventional grinding wheels can grinding 1,000 pcs, perhaps the superabrasives grinding wheels can grinding 2,000 –3,000 pcs. But the superabrasives grinding wheels are always much more expensive than conventional grinding wheels, so the superabrasives grinding wheels do not have price advantage. While for profile grinding, the conventional grinding wheels need frequent dressing while the superabrasives grinding wheels grinding amount can get 50 times or more, so on this condition, the superabrasives grinding wheels are the best choice.
