Repeat this step until the bubble is adjusted to zero at both ends of the Y axis travel

At the column side, look to see which rear corner of the machine if any, is lowest as shown by the leveling tool

Move the X and Y axes until the table is centered

There is a lot of useful information in here

Welcome to this How to Level a Haas Lathe video

Once the height has been set raise the center leveling screws

lower end of the machine to maintain clearance to the coolant tank

Rotate both middle screws up to bring them completely off the middle pads

For DS 30 Machines, you will need to Zero each Axis individually after Starting Up

This provides a uniform position to start leveling

These adjustments should be very small as we are almost finished

Adjustments close to zero will make subsequent changes easier

This reading shows the angle of the machine front to back

The tools need for this procedure are a ratchet and 3 4 socket a 1 1 2 Wrench, Tape Measure and Haas Leveling Tool T 2181

Measure from the base casting lower flange and lift the casting four inches (4 or 100mm) off the ground by adjusting the four corner leveling screws to the same height.

On base castings with 6 or 8 leveling screws the middle screws should not be touching the pads during the leveling procedure

Adjust the lowest corner up until the leveling tool reads zero

Larger machines with outrigger supports require additional steps during the leveling process

If the values are different by more than one division then the level should be returned to Haas for adjustment

Now we will check roll along the X axis

First, the Machine is set to the correct height to clear the Coolant Tank

Mean value of the standard logarithmic distribution

Third, any twist in the Base Casting is removed so the Machine will cut accurately

So the model R squared will not change at all.

The middle screws will be seated in this next step and will be used to align the B and Y axes

Next, measure for any bow, either up or down along the length of the Base Casting

If there is a big difference then this is a larger value and we know for the day in question what the mean and the standard deviation is for this percentage change.

Number to be normalized

Lift the right rear corner of the machine until the leveling tool reads zero

Lock the leveling screws in place

And I'll just call this, what's the probability that I land between 1 standard deviation the mean is minus 5 one standard deviation below the mean is minus 15 and one standard deviation above the mean is 10 plus minus 5 is 5.

Make sure the machine is high enough off the ground to clear the coolant tank

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

With the machine accurately leveled, we move on to checking and adjusting the machine geometrical alignment

After rough leveling the machine front to back and side to side, we will check for roll along X axis travel
