In addition to grinding the cylindrical hole, the jig grinding machine can also grind the inner and outer surfaces of the arc and the conical hole. It is mainly used for machining hardened workpieces, dies and stampers. Install the grinding fittings on the grinding head so that the axis of the grinding wheel is in a horizontal position.
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.
A set of planetary gears in the grinding head runs off the machining center spindle and is used to produce the orbital motion needed to jig bore. For profile grinding, a cam is used in place of the planetary gears. A self-contained U-axis slide accurately positions the grinding spindle for fine finish. Accuracy is 0.001 mm (0.00004 inch).
With a full 3D jig grinder, the simple vertical reciprocating axis is replaced by a servo-controlled Z axis with resolution and speed capabilities similar to the machine's other axes. In the case of the Moore 450 CPZ machine, for example, the Z axis can operate in three modes--reciprocation, positioning and interpolation.

Difference between Jigs and Fixtures: Here is the difference between Jigs and Fixtures: Jigs. Fixtures. It holds and locates the work as well as guides the tool. It holds and locates the work but does not guide the tool. These are lighter in construction and clamping with the table is often unnecessary.
3 THE ADVANTAGES OF JIG GRINDING ARE: • Holes distorted during the hardening process can be accurately brought to correct size and position. • Holes and contours requiring taper or draft may be ground. • Mating parts, such as punches and dies, can be finished to size, eliminating the tedious Job of hand fitting. • Because more accurate fits and better surface finishes are possible, the ...

By design, this jig closely mimics the technique I use when grinding by hand with the exception of guaranteed positioning, reliable consistency, and fewer opportunities for mistakes. Other huge bonuses are the ease of cooling the blade during grinding, and reversing the carbide clamp without interrupting the position of the blade, causing ...
Grinding Jig to work best, your grinder and your grinding jig should both be mounted on a board or a bench so that they can-not move in relation to each other. The base should be mounted directly centered under your grind-ing wheel. Slide the vee-arm into the base to ensure that the centre of the pocket lines up with the centre of your wheel.
and a true side grind can be ground with the jig at any bevel angle. The ONEW A Y V ari-Grind 2 is the only restrained grinding jig that has this function. SKEW JIG Save TIME and MONEY with Oneway's Skew Grind, actually reduces the hollow grind generated and leaves a every time you use it! stronger more predictable tool.
Grinding jigs gives you control of the sharpening. A jig is a device in which you mount your edge tool to achieve a controlled sharpening. Tormek's jigs are developed to give an accurate and safe grinding of most edge tools. You can smoothly sharpen your specific tool to your desired shape and angel, and replicate your sharpening if needed.
I too use pieces of ¾-inch or 1-inch PVC tubing to gauge the V-arm position when using the vari-grind jig. However, I slot the tubing length-wise so it will drop down over the arm rather than having to be threaded over the arm. If one uses a fixed arm angle setting, and a fixed value of gouge protrusion from the jig, then V-arm setting ...
