MRS modular rack system
Modular rack system for flexible probe and stylus changing
Renishaw's modular rack system (MRS) allows customisation of probe and stylus changing racks to optimise CMM functionality.
The MRS is a modular system designed to provide a platform for Renishaw probe and stylus changing racks. It comprises a rail and two leg assemblies, and is available in three different standard rail lengths, 400 mm, 600 mm and 1000 mm (15.75 in, 23.62 in and 39.37 in) to suit a number of changer requirements.
The MRS rail can also be placed at different heights from the CMM's bed by using multiple MRS legs to allow the required clearance for long styli and extension bars.
The standard interconnecting MRS legs supplied (4 per kit) are each 125 mm (4.92 in) long. A maximum recommended leg length of 500 mm (19.69 in) can be achieved by purchasing additional legs. These are available in either 62.5 mm or 125 mm (2.46 in or 4.92 in) lengths. The rack is mounted on the CMM bed via two MRS feet attached to the legs.
Where heavier rack system configurations are to be used e.g. multiple SCP80s mounted to a 1000 mm (39.37 in) rail length, the MRS system can be upgraded by using the optional heavy duty legs which are Ø60 mm × 350 mm long (Ø2.36 in × 13.78 in long). These legs mount beneath the standard legs / feet and are attached to the CMM bed.
The MRS is compatible with the following Renishaw change rack systems:
MRS heavy duty legs
Where an MRS installation has numerous SCP80s containing heavy stylus arrangements, or vertical stylus arrangements exceeding 190 mm (7.48 in), it is recommended that the optional MRS heavy duty leg kits are used to provide additional rigidity / height.
These kits are purchased separately to match the number of legs used in the MRS installation. The heavy duty leg kit stands 330 mm (12.99 in) tall and is positioned between the CMM table and the standard MRS leg assembly.
