The PR Hoffman 43T belongs to the insert carrier category used on double-sided planetary lapping and polishing machines. The insert-carrier selection for this type includes a workhole choice and a thickness entry.[1]
The PR Hoffman 43T fits into double-sided planetary lapping and polishing operations as a carrier used during the material-removal or surface-finishing step. Insert carriers of this class are used after workpieces have been prepared into a form suitable for loose-abrasive or polishing processing and before subsequent cleaning, inspection, or downstream finishing.
