Re check both home positions once you have made any adjustments

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

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

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

Jog the turret to the middle of X axis travel

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

The tool change arm will rotate in reverse and put the tools back into the carousel and spindle

When the coolant tank is full, run each part of the coolant system to check that none of the connections are leaking

However, rapid axis movement is automatically limited to 25 of maximum and the command spindle speed in your program may not exceed 750rpm

I don't have to exit this screen to change an offset

Using the older software, this is what we do if the arm is not contacting the tool

Total Indicator Reading for all four positions should not exceed 0.0005 inches or 0.013 mm

On the keypad, press RECOVER and A for automatic recovery following the on screen prompts

Soft jaws offer several benefits not provided by hard jaws

With the key switch in Setup or Unlock mode and the operator doors now open

The UMC leveling and alignment process is covered in detail in an accompanying video available on the Haas Service site

Errors because of twist or bow will cause errors in the spindle tram values

Remember, spindle speed also affects outside diameter holding force

This time outward against the boring ring

Only the values from front to back can be effectively changed by adjustment of the middle leveling screws

Remove the Air Gun, Operator's Manual and Literature which are zip tied in place inside the Enclosure

My next change

This is done so that the arm doesn't try to pull the tool out of the spindle while the drawbar is still clamping it

On Y axis Machines such as this one the Security Bracket holding the Wedge in place also needs to be removed

Re measuring for Twist and measuring for Bow in the base casting and then measuring the Spindle Sweep.

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
