Custom Pins and Punches

Angles and Tapered Shut-Offs

I.D.'s and O.D.'s

Male and Female Radius on Diameter

Pockets

Grinding walls for pockets can also be done on a jig grinder. A tolerance of .0002" location and .0002" sizing is common. A pocket with a bottom can also be established.

Contours

Basically, the same practice as grinding a pocket. One kind of contour is for male and female cutting dies and punches. One die will be an O.D. One die will be an I.D.

Note: Most pockets and contours would be done on a CNC.

Valve Gate Details

The seal diameter and valve angle are common jig-ground. Any angle can be generated and measured by ball height.

Molding Details

Many different profiles can be established for molding details. Ranging from slight or heavy angles to a specific length or depth along with full radius ribs for example.

Repair Molding Details

Grinding weld and blend to existing diameters, angles, radius' or floors.
