3.4 X and Y Axes Backlash Check
1. Place a (0.002mm) dial gauge against the X-axis of the XY table (Fig.4). Make sure the servo
power is ON, push the XY table left and right by hand to check the amount of backlash.
(Tolerance: 0.010mm.)
2. Check the Y axis in the same manner. Make sure the servo power is ON, push the XY table
backwards and forward to check the amount of backlash. (Tolerance: 0.010mm.)
3. If the amount of backlash is out of tolerance, check the following 2 areas.
a. Ball nut
b. Ball screw bearings
3.5 X/Y Table Squaring Check
Check the squaring of the X/Y table using the jig plate.
(Jig No.: Z9913AWPJ9560)
1. Align the jig in the Y direction to zero using a dial gauge.
2. Indicate the jig face in the X direction to check table squaring.
(Tolerance: 0.015 / 239mm)

3.6 Reference and Adjustable Pin Alignment Check
Check the alignment and play of the tooling pins as follows.
1. The diagram below shows the tooling pin configuration for the CP-643E.
2. To check the alignment of the four pins, place a dial gauge (0.002mm) against reference pin A
and set it to 0.
3. Inch the X/Y table in the X direction and measure the alignment of the three other pins in
relation to reference pin A .
4. Measure at the points indicated in the tables below:
