Installation procedure
Mounting the shank on the probe head
Hold the shank in the recess on the top face of the MH8
Rotate the shank until the three screw holes are aligned
Fix the shank in place using only the M3 × 5 mm screws ﴾supplied﴿
Progressively tighten using the 2.5 mm A/F hexagon key (supplied)
Mounting the head on the CMM
The head will normally be attached to the quill of the CMM using a standard shank, specified by the CMM manufacturer.
Standard shanks are listed in the ‘Part number summary'.
Special or customised mounting arrangements are possible. Please contact your supplier or Renishaw, for details of our custom products
service.
The mounting must be absolutely rigid, as any movement during normal operation of the head will add errors to the measurement system.
If the head is replaced or repositioned in the quill, it will be necessary to requalify all of the head positions in current use.
Electrical connection
Connection is by means of a 5-pin DIN connector on the side of the head.
The pin numbering functions are given in the table below:
