Abrasive Cutting
Abrasive Cutting or rough cutting is the most commonly used method of sectioning materials for metallographic microscopic examination and other material investigation. The usual abrasive cutting uses consumable wheels which are considered the most popular method for routine metallographic sectioning with the aid of metallographic microscope because it is fast, exact and inexpensive. The feature of cut exterior obtained is generally superior to that obtained by other means and fewer following steps may be necessary. Metal core diamond blades complete the difficult requirements of particular applications such as ceramics, rocks, very hard metallics and printed circuit boards, the details of these metals can be viewed under metallographic microscope.
If combined, these two methods of abrasive cutting present a wide variety of cutting characteristics which are capable of meeting the demands of almost any material sectioning challenge. Only through a thorough understanding of the basic principles of abrasive cutting can effective use be made and the broad benefits derived from its application and by the use of Metallographic Microscope.
