effect of rpm to grinding stone

  • A killer combination for ideal grinding conditions

    Grinding is a fairly straightforward process combining four key elements a grinder a grinding wheel a metalworking fluid and a part. Two of these components are fixed — the grinding machine which is rather expensive to replace or modify and the part which must Never exceed the maximum RPM rating indicated on the wheel. For example a 4 -in. wheel rated at 9 000 RPM should not be used on a 4 -in. grinder with a no-load speed of 10 000 RPM (typical for a 4 -in. grinder). Many people remain under the impression that it is the loadoperating speed that cannot be exceeded. This is simply not the case.

An increase of an inch in diameter has big changes on centrifugial forces If a grinding stone has no safe rpm label best to use it by hand only. Improper RPM usage is one of the most common reasons that diamond tools stop working. Higher RPM leads to less torque which means a higher risk of the tooling losing traction and spin out. Therefore it s always safe to check what the optimal RPM is for the tool you are working with. Grinding Wheels and Blades

For concrete and masonry products the optimum speed range for recommended RPM is /-10 (based on 9 500 SFPM-Surface Feet Per Minute) of the speed shown in the chart. For hard and dense materials ( stone hard title etc.) the optimum speed range for recommended RPM is 10 to 25 less than the speed shown in the chart.

Most machines and especially CNC machines use Surface Feet Per Minute (SFPM) as an input which requires operators to do the conversion. This invention relates to methods and materials for slip ring grinding of a generator rotor without the need of dismounting the slip ring from the rotor of the generator and allowing the grinding process to be performed whilst the generator is on full-load operation.

    Dec 17 2010 · There is also the issue of the hardness of the wheel bond and the effect that the SFM has on the apparent hardness of the wheel. So for an 8" grinder running at 1800 rpm you d want a harder wheel bond than for 3600 rpm. A hard 8" wheel running at 3600 will resist shedding dull grains and need frequent diamond dressing. Grinding is generally considered to be a size reduction operation. However in most cases the primary objective of grinding is the liberation of valuable minerals from gangue material irrespective of the amount of size reduction required. If fracturing of an ore occurs in a random manner it may be possible to use the grain size distribution of the valuable mineral phase in the unbroken ore
