    There is a range of tools available to assist with readhead installation depending upon the system design and these are detailed below. For more details on designing the mounting bracket and selecting the appropriate mounting tools contact your local Renishaw representative.
  • Page 26 Shim kit (A-9401-0050) Required parts This method is intended for applications where the rideheight of the readhead cannot be adjusted. • Dial test indicator (DTI) or similar The system should be designed to achieve a nominal 2.3 mm (±0.2 mm) from the readhead • 2 M2 × 6 screws mounting surface to the top of the scale.
  • Page 27 100 µm a single shim should be used; for distances greater than 100 µm select one thick (≥ 100 µm) and one thin (< 100 µm) shim. Care must be taken to ensure the scale surface is not scratched. Renishaw offer a DTI In the above example of a required shim thickness of 130 µm this could either be: adapter that can be used to assist with this process.
  • Page 28 ‘nose’ that is machined to the optimum rideheight (2.5 mm ±0.02 mm). It is mounted in place of the readhead directly onto the bracket. The bracket should have location pins or a shoulder to control readhead yaw. Contact your local Renishaw representative for more Shoulder information on bracket design.
