MIC TRAC MT-3000 2 2010 Gagemaker, LP

RCDMMT300010-10

Materials Needed: • MIC TRAC MT-3000 base unit and CPU readout • 5/32" hex wrench • Depth micrometer • 50 in/lb torque wrench • Depth gage fixture (TF-DG) and cap screws • Cloth • Flat face anvil (TF-1F Block) cap screws and washers • ZEP I.D. Red cleaner • Depth gage support (TF-SS Block), for rods 6” and up 1. Inspect the depth micrometer visually as

follows: • Check for damage and excessive wear. • Check for burrs, nicks and wear on measuring

faces. • Check for damage to measuring rods, rod

seating surfaces, and rod reading surfaces. • Inspect for slack in the spindle thread by

pushing the assembly in and out. Adjust to remove excess play.

• Check for proper function of the friction or ratchet stop and spindle locking device.

• Check for smoothness of travel by rotating the thimble throughout the range.

• Ensure all rods are straight.

2. Clean both of the receiver pads and the

mounting surfaces of the flat face anvil using the cloth and ZEP I.D. Red cleaner.

3. Locate the left flat face anvil. Place the

shoulder side of the anvil against the left receiver pad shoulder.

Setup

4. While holding the anvil against the receiver pad

shoulder, insert the two cap screws with washers into the holes on either side of the fixture.

5. While applying pressure toward the receiver

pad shoulder, use a 5/32" hex wrench to slightly tighten the screws.

6. Use a 50 in/lbs torque wrench to secure the

cap screws.

7. Locate the depth gage fixture and clean the

mounting surfaces with the cloth and ZEP I.D. Red cleaner.

8. Place the depth gage fixture against the right

receiver pad shoulder with the thumb screws facing to the right. Insert the cap screws.

12. Zero the depth micrometer on a flat surface

and lock the spindle.

13. Retract the thumb screws on the depth gage

fixture enough to fit the depth micrometer.

14. Mount the depth micrometer in the depth gage

fixture, aligning the depth micrometer’s rod with the center of the flat face anvil.



RCDMMT300010-10

15. Secure the depth micrometer by holding down

on the base and tightening the thumb knob on each side of the depth gage fixture.

16. Turn the coarse adjust knob counterclockwise

until the depth micrometer barely touches the flat face anvil.

17. Apply slight pressure until the in the

axis display lights up. The display will read 0.00000 and the gaging force will be preset to 2.0 lbs of force.

Materials Needed: • MIC TRAC MT-3000 base unit and CPU readout • 5/32" hex wrench • Seiko printer (optional) • Lightweight gage oil • Depth Micrometer • Gage Calibration Record 1. Turn the fine adjust knob clockwise to bring the

depth micrometer face in contact with the flat face anvil.

2. Verify that the readout on the CPU displays

0.00000.

3. Loosen the coarse adjust lock and turn the

coarse adjust knob clockwise to slide the movable carriage to the right.

4. Adjust the depth micrometer to the first

calibration value. Note: If you pass the calibration value, turn the

spindle back and approach the value again, from the same direction. This practice will increase the accuracy of the calibration.

If using a computer with the MT-3000, go to page 11. Calibration

until the depth micrometer rod barely touches the flat face anvil.

6. Secure the coarse adjust lock.

7. Turn the fine adjust knob clockwise until the

- in the axis display lights up. If you have a Seiko Printer attached to your MIC TRAC a permanent record of the measurement prints.

8. Record any deviations on the Gage Calibration

Record or in-house calibration report. Continue with remaining measurements for the first depth rod.

Note: It is recommended that depth rods 6” and longer be supported during calibration. 9. Locate and mount the TF-SS support. With the

thumbscrew facing forward, slide the support over the flat face anvil.

10. Remove the depth rod from the depth

micrometer and insert the next depth rod. Adjust the height of the depth gage support to hold the end of the depth rod, so it does not bend during calibration. Tighten the thumb screw.

14. Remove the depth micrometer and continue

with the same calibration process for the next depth micrometer.

15. After calibrating all depth micrometers, be sure

to remove the depth gage fixture and flat face anvil from the MT-3000. Oil the fixture and anvil and return them to the storage case.

14. Enter the first measurement in the Measured

column as follows:

• Continue turning the Y axis adjust knob until the X axis moves approximately ½ inch. Secure Locks 1 and 2.

• Click the Send to Table bar. CERTIFI records the value and displays a green box in the Pass/Fail column if the value is within tolerance. A red box displays if the value is not within tolerance. The Deviation column shows the deviation of the measured value from the master value.

15. Adjust the depth micrometer to the first

calibration value. Note: If you pass the calibration value, turn the

spindle back and approach the value again, from the same direction. This practice will increase the accuracy of the calibration.
