Chapter 3 Static Accuracy Measurement

3.1 Checking the straightness of the X/Y axes

• Jig: Perpendicular measurement jig Z9531DEPJ0050.

• Equipment: Lever type dial gauge (0.01mm).

1. Attach the dial gauge to the placement head (an extension bar is necessary).

2. Place the perpendicular measurement jig (Z9531DEPJ0050) on to the main conveyor.

Adjust the jig position so that when running the dial gage along the jig in the X direction,

the 0mm and 300mm point values are both 0 (i.e. the jig is parallel to the X axis).

Note: If the XY-axis squareness needs to be measured, it is better to perform

measurement (3.2) first, before measuring the Y-axis straightness.

3. Measure the Y-axis straightness in the same way as the X-axis.

Note: measure in the part placement area of the main conveyor.

3.2 Measuring the squareness of the XY axis

• Jig: Perpendicular measurement jig (Z9531DEPJ0050).

• Equipment: Lever type dial gauge (0.01mm).

1. Load the perpendicular measurement jig on

the conveyor, and position it so that the X-side

is parallel with the X-axis.

2. With the jig in this position, measure the Y-

direction side. This indicates the Y-axis

orientation which is perpendicular to the X-

axis.

Note: measure in the part placement area of

the main conveyor.

3.3 Z-axis verticality measurement

• Jig: Cylindrical jig (Z9531DEPJ0060).

• Jig: Platform plate jig (Z9531DEPJ1080).

• Equipment: Lever type dial gauge (0.002mm).

1. Set the platform plate jig as shown in the diagram below. Set the cylindrical jig on the

platform plate jig. Ensure that no dirt, parts, or other foreign matter obstruct the balance

of the jigs.

2. Set a mini magnetic dial gauge stand on the placing head at the end of the Z axis spline

shaft. Set the tip of the dial indicator on the most forward part of the cylindrical jig vertical

surface (point C in the diagram below).

3. Measure the straightness of the Z-axis. The range of measurement is from 2mm above

the minus stopper to 32mm above the minus stopper (a stroke of 30mm).

4. The difference in straightness between these two points should be within 0.03mm.

5. Repeat for the right hand side of the cylindrical jig.

3.4 Checking the Z-axis nozzle disc surface

• Equipment: Lever type dial gauge (0.002mm).

Face oscillation measurement

1. Position the Z axis 2 mm above the Z-axis minus stopper.

2. Put a dial indicator against the underside of the nozzle disc and measure the surface

oscillation by turning the Q-axis through 360 degrees.

Nozzle pick-up surface parallelism measurement

1. Position the nozzle pick-up surface 2 mm above the Z-axis minus stopper.

2. Set a dial gauge on the underside of the nozzle disc, and measure the difference in

flatness from one side of the disc underside to the other. Measure in both the X and the

Y-direction.
