TOOL REGRINDING & RECONDITIONING - Conical

Regrinding reduces the diameter of the end mill and causes the radial rake angle and hook to recede. In general, reducing the diameter by the below equations can still maintain effectiveness by up to 80% of the original tool.

for fine regrinding - fortunately it is also possible with relatively small samples (15 kg). • Direct measurement of energy consumption from the agitator shaft, in the same way that energy is measured for full scale mills. This also done to accurately subtract the no-load power ensuring the lab mill will scale-up to any size mill.

Milling – fritsch.de - Milling and Sizing

The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these factors are significant.
