Dummy Kit - Renishaw ATOM Installation Manual

Dummy kit

Suitable for:
• Applications where the readhead mounting bracket allows adjustment of rideheight
The reusable dummy head is mounted directly onto the bracket in place of the readhead.
It has the same dimensions as the ATOM readhead with a longer 'nose' that is machined
to the optimum rideheight (2.5 mm ±0.02 mm). The bracket should have location pins or
a shoulder to control readhead yaw. Contact your local Renishaw representative for more
information on bracket design.
Required parts:
• Dummy head (A-9401-0072)
• 2 × M2 × 6 screws
• Customer designed bracket
• 2 × bracket mounting screws
• ATOM readhead
1. Mount the dummy head onto the bracket using two screws.

3. Adjust the height of the bracket or disc assembly until the 'nose' of the dummy head touches
the disc.
4. Tighten the bracket fixing screws whilst ensuring good contact between the 'nose' of the
dummy head and the surface of the disc.
5. Remove the dummy head.
6. Install the ATOM readhead in place of the dummy head using screws in diagonally
opposite fixing holes.
