This required precision jig grinding in two diameters – one at roughly Ø.500", with the other at roughly Ø.400. Keep in mind that both needed to be within ±.0001" – absolutely no exceptions. Because of the tighter tolerances, temperature can quickly become a concern due to the high coefficient of thermal expansion for aluminum materials.

By jig grinding, you leave them shallow before heat treat, and simply use a CBN wheel or carbide cutter to very quickly grind the depth perfectly. This is much faster and easier than hard milling or guessing at the depths when grinding. Bosses and similar details Why use EDM machining them when you can do it in a fraction of the time?

We bought a used jig grinder and it's grinding on a bell taper small at the top big at the bottom. I know that the little sight markers need to be lined up or it will grind a taper. They are pretty close but obviously not correct. Is there an easy way to straighten it out, maybe with an indicator. Please help !!! Thank you.

Jigs are often used in drilling, reaming, counterboring, tapping and other one-dimensional machining operations or applied as guides for tools or templates.

When I grind a tool at the 40 degree setting and measure the grind on the tool it comes out 32 degrees. Which cuts incredibly clean by the way. So you can see my confusion. For years I just grind a tool like I want and then build a plywood jig that sits on the tool rest and touches the wheel at 2 points. This is extremely repeatable.

The jig and fixture generally function in securing the workpiece and machine parts. However, there is a difference between both. With the fixture, the tool does not move when the workpiece moves. This is not so with the jigs where the tool moves. Depending on the types of jigs and fixtures, you might need to clamp also.
