QA Table
Error in each head in Y-direction with reference to R head: ±0.02 mm (eccentric center as measured at the Z
pickup position)
Mount heads on the head plate and fit the jig nozzle (φ20) to the head that serves as the reference (normally R
head; the head mounted if heads are replaced). With the center of runout in the Y-direction at 0, move the head
in the X-direction. Remove the jig nozzle and, instead, mount it to the head to be measured. Select head
center shim A, B, or C and place it between the head plate and head bracket so that the error in runout center in
Y-direction becomes ±0.02 mm. Measure, at this time, the Z position at the pickup point [see the assembly
drawing of head assembly (750, 760, 7520, 7620)].

QA Table
Squareness of the right-hand-side machined surface of the R head with respect to the reference pins (at two
places) of the head plate assembly: 0.03 or less
Check procedure:
Using the square master, measure the machined surface on the right-hand side of the R head with respect
to the reference pins (at two places) of the head plate assembly. If the head plate assembly is connected to
the X-axis frame assembly, measure squareness with the head plate at around the center of the X-axis
frame.
Reference pin
A
Adjustment procedure:
Loosen fixing screws (a) (at four places) of the R head, move the head about positioning pin (b) to meet the
specification value, and then screw the head in position.
