Jig grinder

A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required.. The jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate (far more so than a manual milling machine or lathe).It is almost exclusively used by tool and die makers in the creation of jigs or mating holes

Grinding & Classification Circuits

Fines enhance the viscosity of the slurry in the mill. This means that the slurry will adhere more readily to the balls This results in slurry being incorporated in the bulk of the grinding mass rather than draining to the toe of the mill. Higher overall grinding rates result from the enhanced use of active zones of the grinding .

Drill Sharpening On The Quorn

Standard conical sharpening produces a point angle of 118 degrees, but it's not a cone. The actual tip is a straight line when viewed end-on, and an arc when viewed from the side. This is called the "chisel edge" (ref [WSP12]). This is an artifact of the sharpening process and is formed by the intersection of two conical sections.
