AM1 adjustment module

The AM1 adjustment module has been
designed for use with the PH6M and MIH
manual probe heads and the PH10T/M
motorised probe heads. It provides quick and
accurate angular alignment of the probe head
with the CMM’s axes and/or the autochange
rack.

In addition, the quick release mechanism
allows the head to be removed for storage and
subsequently replaced without re-alignment.
Built in overtravel protection decreases the risk
of head damage.

2 Locate AM1

Locate AM1 body to probe head and
secure with M3 x 6 mm screws. Use
three screws for PH10M and PH10T.
See figure 2 for top views of probe
heads and screw locations.

3 Refitting the mounting plate

Refit mounting plate to AM1 and locate
by rotating through 60°. Screw yaw
adjusting screw against lug.

NOTE: If shank / mounting plate
assembly is to be permanently attached
to the head, the safety screw should be
replaced before assembling the shank
on the mounting plate. Alternatively,
if quick release is required, the screw
should be left out.

4 Secure shank

Secure shank to mounting plate with four
M3 x 5 mm screws provided. Do not use
longer screws.

6 Pitch adjustment

Rotate the pitch adjustment capstan to
increase or decrease pitch. Refer to
figures 4 and 5.

7 Yaw adjustment

Release the lock screw. Rotate the yaw
adjusting screws equally in opposite
directions to provide required yaw. Tighten
the screws against each other without
applying excessive torque. Tighten the
lock screw. Refer to figures 4 and 5.

8 Quick release of AM1 from shank

NOTE: If repeatability of position is

required on re-attachment, DO NOT alter
the centre screw. This repeatability of
position is sufficient for alignment with
the autochange rack, but probes must be
redatumed for measurement.

Rotate AM1 until free and remove.

9 Re-attachment

Locate AM1 against the shank and rotate
until engaged. Tighten the yaw adjustment
screw. Tighten the lock screw.
