This chart adapted from an article in Korea s Blackwater Issue shows the grind size distribution changing as the burr speed changes with the higher RPM resulting in a smaller median grind size and more fines However this effect appears to be very similar to the effects of simply changing the grind setting as shown in the graph below
Coffee grinder differ not just between brands but between models and even individual units The same two grinders made in the same factory on the same day can drastically vary in grind size distribution — as most manufacturers don t calibrate or align the burrs to
The chart shows the midpoints for the size ranges for ANSI/CAMI graded paper according to ANSI standard 1996 and for FEPA graded paper according to FEPA standard 43 GB 1984 R1993 A Planar grinding machine IsoMet ® High Speed & High Speed Pro;

As we move higher in angle grinder sizes the rotational speed of the disc becomes less A 5 Angle grinder has a speed up to 10 000 RPM while a 6 one has a speed between 9 000 RPM to 10 000 RPM The 7 angle grinder is another popular size in the larger angle grinder category They have a powerful 13 amp or 15 amp motor and
The fifth factor to consider is the wheel speed We have to consider the operating speed of the wheel in surface speed To calculate surface speed use these equations or try our iGrind app on the App Store and Google Play Wheel speed determines what bond type is most suited for the required speed or if a special high speed bond might be required

5 The grinding wheels indicated in this chart are vitrified glass bonded abrasive products Although by nature glass products are relatively fragile these wheels are Never over speed a wheel Maximum Operating Speed MOS indicated on a wheel should never be exceeded in terms of surface feet per minute 4 Be sure the wheel fits the
In the equation of Time for Cylindrical Grinding Cut Length of Cut = Length of job Over Travel where Over Travel equals to cm And Feed/Rev = w/2 for rough cut or w/4 for finishing cut
This less severe over speed condition can cause the wheel to be damaged and the damage may result in breakage after further use For example operating a reinforced 9 inch diameter Type 27 wheel rated for a maximum speed of 6 600 rpm on a 7 inch angle grinder with a speed of 7 700 rpm can cause the wheel to crack

I m afraid that this will be a bit of a cheat — I m going to try to crowdsource an understanding of this Let s start by looking at all the variables Material being cut — this should be groupable into a couple of categories ideally matched up with typical endmill manufacturer recommendations Hardwood Soft plywood MDF/Particle board Plastic hard Plastic soft
For example a grinding wheel moving at 12 000 sfm 3 657 m/min requires a nozzle pressure close to 270 psi bar for the coolant jet to match the wheel speed Lower wheel speeds require lower pressures The chart below shows the pressure required for water based synthetic oil and mineral oil coolants to achieve the desired jet speed
