Electrolytic Polisher Cum Etcher
| Introduction | Electrolytic Polishing is an electrochemical process for preparation of Metallogrpahic samples. It is a reverse process of electroplating, wherein the material from the samples is removed away by electrolytic action in presence of D.C. Potential. Electrolytic Polishing renders distortion free finely polished samples in seconds. In terms of quality, speed and ease of operations, electrolytic polishing exceeds mechanical polishing methods. |
| Necessary and optional Accessories | POWER SUPPLY UNIT. A 150 volts, 2.5 amps. DC supply source operating on 230 volts 50 cycles single phase AC mains. DC voltage varies with the help of a dimmerstat voltmeters with ranges 0-15 V and 0-150 V. Ammeters with ranges 0-250 MA and 0-2.5 A.DC. Three station selects for polishing, etching or external etching. An electronic timer 0-100 seconds for etching and 0 to 220 seconds for polishing. For timings beyond this range manually controlled polishing facility is provided. Polishing Table supply point include AC voltage for electrolyte pump having variable speed and DC source for polishing etching. Additional point for external etching is also provided. Supplied in sturdy cabinet with all the controls located in front. |
