Description

Semiatomated machine for preparation of materialographic samples by mechanical grinding and polishing. The clamping system accepts samples embedded in 30 mm stubs, produced by Citopress 10 or Citovac machine. Minimum number of samples to be processed is one; maximum number is 6 samples per run. The machine is quipped with automatic six-line dosing system for process fluids (wetting agent and polishing suspensions) and one dosing line dedicated to supply chemically active polishing fluids.
