Re check both home positions once you have made any adjustments

Jog the turret to the middle of X axis travel

When the machine is built, the table is made parallel to the B axis therefore we can use the table surface to set B axis parallel to Y axis

The calibration process is covered on the Haas Service site

Push the RECOVER button

Use the precision level vial parallel to the turret for this measurement

So that is my y axis, and this is my x axis.

On a number line, our Total Indicator Reading is three ten thousandths (0.0003 or 0.0076mm) TlR which puts our spindle sweep measurement in specification

So let's graph it.

So I'll just draw this kind of a general graph right here.

So that's the real part.

It is also possible that the arm is stuck while gripping a tool that is still clamped in the spindle

But keep material removal to a minimum, to get the most life out of your jaws

Press LlST PROGRAM and then select the Memory tab

Below the tool offsets are the work zero offsets

Select program O02020 Spindle Warm up and press SELECT PROGRAM

All right, there we go.

It's going to look something like that.

So let's draw this.

It's going to be in the negative quadrant.

This is going to be this function evaluated at c.

This is the horizontal axis over here is the x axis

Let me draw it like this.

And if you want to care about x, y's, and z's, let's say that this is the z axis.

You could make the vertical axis.

Let me draw my axes here.

Later we will check and adjust the B axis home position
