Magnetic universal chamfer deburring machine by using the universal grinding wheel to rotate alternately at high speed, the sanding wheel slid over the working angle surface, and the burrs are evenly removed and evenly chamfered. The main function is polishing the position of chamfer, and the friction on the flat surface is very small.

Surface Grinding of copper... Easy. Use a solid metal wheel - a dead soft aluminium, and a hard and fine compound - such as a automotive valve lapping paste for a fine finnish. The hard material embeds in the aluminum, and this grinds the copper away.

Blanchard Grinding for Parts of All Shapes, Sizes & Materials. Also known as rotary surface grinding, Blanchard grinding is most commonly used to process large surface areas or larger parts. However, Petersen Precision can also effectively Blanchard grind smaller parts by grouping them together and processing multiple workpieces at once.

For example, double disk grinding can achieve surface finishes of up 16 Ra µin (0.41 µm) on aluminum and up to Ra 8 µin (0.20 µm) on ferrous alloys. Flat lapping is another abrasive process often considered an alternative to double disk grinding for tight control of surface finish, flatness, thickness, and parallelism.

Vibration in your Surface Grinding Machine during the grinding process is critical from the point of view of wheel life and surface finish of the work-piece.

Stones are not used for grinding. Wheels are. For grinding aluminum, a silicon carbide wheel (not a green one) is the best choice, but grinding aluminum isn't in your best interest, as it, like mild steel, will not respond well to being ground on one side only, and there's always the problem of holding the material while it's being ground.
