Clamps

Klump, it's me.

You know, you create power, then you tame it. (Music)

get the clamps ready.

He finds a four thousandths of an inch (0.004 , 0.102 mm) space, so he will start by adding a 1 4000 taper to the jaws

And instead of throwing it out, people would think that's a krump move, that's a krump move.

The clamping force on the part naturally decreases

Andrew cuts the taper in the jaws With the taper cut and the work piece clamped at full pressure

Shlubb and Klump were packing an arsenal.

I tell them to create a ball, and then you just use that ball of energy.

The result would be jaws that have very little travel remaining to grip the part, past the nominal diameter

Counter clockwise, to bring the adjustable dowels inward slightly

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

To do this, unclamp the jaws and rotate the threaded body of the boring ring to adjust the position of the grippers

These slide along the slotted ring body during adjustment

In the same direction that you will hold the work piece

Now Andrew uses a slow drying bluing compound to check if he needs to make another slight taper cut

Our program is set to cut at the nominal part diameter

The air line must have an inner diameter of at least 1 2 (13mm), all the way from the source to the machine

When the soft jaws are held tight for cutting, the master jaws should be at the middle of their travel

To demonstrate a more extreme scenario we move on to these tall 4 inch aluminum jaws

The shields are weakening the clamps, but they're still holding.

The jaws will deflect away from the part

The boring ring is now clamped at the center of the stroke

But don't exceed the manufacturer's specifications

If he were to use regular soft jaws to hold this thin walled part

The jaw grippers are now facing outward

Burt Shlubb and Douglas Klump... two anydirtyjobthereis thugs with delusions of eloquence.

Aluminum jaws are typically used to grip light weight or hollow parts where clamp force is low

They were bored very deep, at a clamping pressure of only 50 psi

With the bore for our plug complete

And lock in place against the ring when the jaws are clamped

This set of short steel jaws was bored to one inch deep while being held at 100 psi

Next we have these short aluminum jaws, cut with a 1.5 inch deep bore, also at 100 psi

First, we need to choose whether we'll use aluminum or steel jaws

Each jaw is pushing with 19.6 kilonewtons of force, or thirteen thousand pounds of total force

Also visualize the amount of force you will be clamping with

At higher holding pressures the ring would begin to distort during clamping

Laboratory clamps make it easier to hold many kinds of tools.

In this case, the spindle drawbar will need to be set to the unclamped position during the tool removal

To start, press tool release to unclamp the drawbar

Since the idea is to machine away material to correct the jaw inaccuracies

And for variations in work piece size when the jaws are used later in production

The difference of 30 psi between these two pressures is not enough to cause problems on this particular part

Again we clamp the machined slug at 300 psi and although you might think
