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.

3.5 Measuring the parallelism of the U-axis
tray and fixed rail
• Equipment: Lever type dial gauge (0.01 mm).
1. Attach the dial gauge to the placing head (an extension
bar is necessary).
2. Moving the dial gauge along the Y-axis, measure the side
of the fixed rail as illustrated in the diagram.
3.6 Measuring the flatness of the U-axis tray
• Equipment: Lever type dial gauge (0.01mm).
1. Attach the dial gauge to the placing head (an extension
bar is necessary).
2. Measure the flatness (of the plastic bar) at the tray parts
pick-up position.
