Abstract
A platen for a metallographic grinder has an outer peripheral rim with an upper surface having a lower height. Also, fingers engaging a specimen are allowed to move laterally (i.e., wobble) to minimize the tipping forces on the specimen during the grinding process. Either one or both of these structures can be employed and results in a much flatter specimen surface for use in subsequent analysis.
