Thread Whirling What is it, and How Does it Work? What is Thread Whirling? Thread Whirling is a form of the Thread Milling process with the exception that the cutters are mounted on the inside of a Cutting Ring or Cutter Holder rather than the outside of a milling tool.
To achieve the best results, however, the position of the specimen holder, relative to the platen, must be adjusted so that the outer edge of the specimen holder rotates out over the edge of the surface on the platen during grinding and polishing, particularly for 8in [203mm] diameter platens.

The Precellys Evolution homogenizer can process five different sizes of tubes ( in wellplate format,, 2, 7 and 15mL) and up to 24 tubes simultaneously. Its flexibility and high efficiency give users the ability to grind, homogenize or lyse any type of soft or hard sample from animal, human, plant or microorganism sources in seconds.
Make sure that after PG the surface of all samples in the specimen holder shows the same uniform scratchpattern over the whole surface. Repeat PG if necessary. To avoid contamination of the grinding/polishing surface through large abrasive particles from a previous step, clean the samples and sample holder carefully after every step.
Grinding time can be increased in specified intervals and retested; the optimum grinding time can be timed when the analysis does not change significantly when more grinding time is added. Higher samples will generally require more grinding time, a grinding time of 5 minutes is typical for raw mill cement ad finish cement in 4 minutes is ...
