Abrasive Processes

Jan 01, 2015Honing is the finishing process that renders the smoothest surface texture and the greatest accuracy. The abrasive is made into a slab (stone, stick), and is moved in a rapid oscillating motion over the surface (usually a hole) to be finished (Figure 3.3a).Superfinishing is a variant in which oscillating motion is imparted to a fairly large stone, and the surface pressure is kept very low.

Grinding Processes

Grinding is the common collective name for machining processes that utilize hard, abrasive particles as the cutting medium. The grinding process of shaping materials is probably the oldest in existence, dating from the time prehistoric humans found that they could sharpen their tools by

Towards High Productivity in Precision Grinding

For example, a particular process known as in-process electrolytic dressing, (ELID) is employed in a grinding process to mirror-grind silicon wafers [2,40]. Electrolytic dressing exposes the abrasive grains and thus allows a grinding process to take place. Grinding replaces a lapping process with much improved productivity and accuracy.

ADVANCED FINISHING PROCESSES (AFPs)

Gap between the workpiece and the pole is filled with a magnetic abrasive powder. Magnetic abrasive grains are linked to each other magnetically between the north and south magnetic poles along the lines of magnetic force, forming a flexible 2-5 mm long magnetic brush. MAF uses this magnetic abrasive brush for surface and edge finishing.

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive ( 40 m) is used. Grinding is quick and relatively easy process but can
