HOW TO CALCULATE DOSAGES. We first need to identify the percentage of THC in the strain weâre using as raw material for our edibles. Most of todayâs strains are tested somewhere between 15-20% of THC when grown properly, some weaker material might only have 10%. We will calculate with 10% to simplify things:
Cylindrical grinding (also called center-type grinding) is used to grind the cylindrical surfaces and shoulders of the workpiece. The workpiece is mounted on centers and rotated by a device known as a drive dog or center driver. The abrasive wheel and the workpiece are rotated by separate motors and at different speeds.
Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are Â± 2 Ã 10 â4 inches for grinding a flat material, and Â± 3 Ã 10 â4 inches for a parallel surface (in metric units: 5 Î¼m for flat material and 8 Î¼m for parallel surface).
