Let's find out just how much taper should be added to the jaw bore

This graphic illustrates what would happen if you did not cut to the nominal part diameter

Then as he removes each jaw, he numbers it

Just a teeny bit longer.

Andrew positions the jaws outwards until the t nuts are near the edge of the chuck body

High jaw force deforms both the jaws and the work piece

Remember there should be a balance between holding force and deformation

As you look at your setup, visualize the direction you will be clamping in

And applies a coat of the compound to the edge of the jaws where they meet the work piece

To demonstrate the loss of gripping force we will use this electronic gauge

Instead, refer to your chuck documentation to find a balance between grip center height and clamping force

The wind is good.

These slide along the slotted ring body during adjustment

Just as they will when holding the part Although there are many factors that you should take into account when choosing regular vs pie jaws

And with our program set to cut both pockets to the nominal size, we are ready to cut our jaws Two step jaws are a good alternative to cutting two different jaw sets

Remember, it doesn't matter where we start.

The master jaws are at the center of their stroke. Now we're ready to cut these jaws Once the jaws have been cut, make a shallow groove at the bottom of the jaws

So all the red sides, for example, face one direction south.

Turn around.

Should always be cut to match the nominal work piece diameter

They go in opposite directions while they generate their spindle fibers.

But we're still along the same line, right?

Away the damage control parties.

When the pressure needed to hold the part is much higher than the pressure that was used to cut the jaws

It then reduces y over time to go into negative territory.

After the taper is cut and the correct force is applied to the work piece

It straps under your chin just so.

For both outside holding and inside holding jaws

We go from the situation to that situation.

We're heading to the C.D.C.

With the jaws pushing outward against the boring ring at 100 psi

Finally, he got I suspect

So just a little less chin.

Side of your eye. Side of your eye.

Which matches the direction and pressure we'll use when cutting the parts

Particularly at extreme differences in clamping pressure and at very long jaw lengths

This affected my entire body.

It would be the exact as x minus y, but just in the opposite direction.

If I were to do minus 10, I would get a vector going in this direction that goes way like that.

Before we mount the jaws

This design allows for slight changes in clamping position to be made easily

It will taper each wall four thousandths of an inch (0.004 , 0.102 mm)

All right. Now we'll start on the mouth and chin.

He has a beard.

In this case, since we can't use a boring ring, consider using a plug of material to hold the jaws in position
