Rotary surface grinders, commonly known as "Blanchard" style grinders, have a grinding head which rotates the grinding wheel on a vertical axis cutting on the end face of the grinding wheel, while a table rotates the work piece in the opposite direction underneath. This type of machine removes large amounts of material and grinds flat

Blanchard grinding (rotary surface) has a large stock removal rate on flat surfaces. Ferrous materials are held on a magnetic chuck while the opposite surface is ground. One side is ground at a time. Non-ferrous materials can also be ground, but require special work holding arrangements. Blanchard Grinding will leave its trademark cross-hatched

Double disc grinding offers a highly productive and accurate means for machining to-size parts with flat and parallel sides. In this grinding method, two opposed abrasive discs, each mounted on its own spindle, simultaneously grind opposite and parallel faces on pieces traversed between them via any of several fixturing/carrier techniques.

Jun 01, 2021Fig. 1 shows the principle of abrasive belt grinding and the contact deformation at grinding interface. The material removal during the whole machining process is achieved by the relative motion between grains and workpiece materials under the joint action of normal pressure F n and tangential force F t.The contact deformation at the grinding interface is caused by the elastic

Concrete grinding is the process of removing high points, contaminants, and loose material from a concrete surface using a grinding machine. When grinding concrete, the bond of the diamond cup wheels should normally be the opposite of the concrete, ie use a soft bond on hard concrete, and a hard bond on soft concrete.
