MCR20 probe module changing rack kit

The MCR20, can be easily mounted onto a CMM using the Renishaw SCR200 mounting kit and location piece, and the MCR20-R can be easily mounted to an MRS or MRS2 rail using the XCR to MRS adaptor kit. These racks are designed to securely hold stored probe modules for automatic changing, and to protect these stored probe modules from airborne contaminants that may be present within the working environment. Only seven datum points are needed to set the MCR20 rack alignment and probe module changing co-ordinates.

When using the rack, the inhibit version of the TP20 probe must be used. By generating a magnetic field about the front of each docking port lid, the MCR20 effectively ‘closes' the probe's inhibit switch during a probe module changing cycle. Rack function is completely passive and no electrical input is required.

During automatic changing of probe modules, limited crash protection is provided by hinged overtravel mechanisms incorporated within both the base and the docking port assembly of the leg mounted MCR20. Provided any collision occurs in the direction of overtravel, the hinged overtravel mechanisms can be manually reset and it should not normally be necessary to re-datum the rack.
