Metallography is the study of the physical structure and components of metals, typically using microscopy. Ceramic and polymeric materials may also be prepared using metallographic techniques, hence the terms ceramography, plastography and, collectively, materialography.
FIRST STEP- SECTIONING
METALLOGRAPHY SAMPLE PREPARATION FEATURE
Sectioning is the most important step in preparing specimens for physical or microscopic analysis.
SECOND STEP- MOUNTING PRESS
During the polishing step the embedding (mounting) permits to limit the edge effects For manual polishing, it is easy to grip the sample. For automatic polishing, it is good to gather a number of sample in a sample holder under tightening conditions.
Two kind of resin to choice :
Cold resins for fast operation
Hot resins for minimum shrinkage, but you need mounting machine
THIRD STEP - GRINDING POLISHING
To prepare the cut surface suitably for metallographic examination as optically flat, reflective, smooth and scratch free ▪ Machining ▪ involves the use of tools having cutting edges of controlled shape like sawing, lathe turning, milling, and filing . Two complete method of pre-polishing (grinding) and polishing, which combine polishing support and abrasive.
Automatic hot mounting press GIS-AM is latest new model, automatic pressure, touch screen controls, electro hydraulic pressure, noise level below 48 decibels available to the most popular inch and mm size.
Semi automatic metallographic secitioning machine GIS-MC200 is basic model, good for limit budget also need manual cutting customer but contain all the same design as automatic model and same standard accessories.
