Relief is usually not noted until polishing begins, so it is important to begin the preparation with grinding media that will keep the samples as flat as possible. However, for the best possible starting conditions, MD-Largo should be used for fine grinding of materials with a hardness below 150 HV, and MD-Allegro should be used for fine ...
Particle sizes are commonly classified by mesh sizes, often given a range, for example: 30/60. This indicates that 95% of the mix will fall through a 30 mesh but not pass through the 60. The mesh size number indicates the number of mesh lines per square inch in a sieve, ranging from 6 (coarse) to 327 (powder).
Apr 29, 2010· Anywho, here's what Alcotec recommends: GRINDING: · Wheel grinding is not recommended since it smears the surface of aluminum and can deposit organic binders from the wheel during grinding. · Disc grinding can be used with grit size, 30 to 50 preferred, and speeds of 4,000 to 6,000 rpm's.
