LK Metrology Introduces Cost-Effective Modular Change Racks for CMMs

Castle Donington, UK – Racks mounted on the granite table of a coordinate measuring machine (CMM) for storing styli, probes, adapters, and laser scanners, allowing a head mounted at the end of the spindle to exchange them automatically, are essential to enable efficient CNC inspection and measurement without time-consuming manual intervention. Until now, good-quality racks have tended to be expensive, but a new range offered by LK Metrology, Inc is said to be more affordable. 

Having more ports than other rack systems on the market, the units are available for use not only on CMMs manufactured by the company in Castle Donington, UK, but on other makes of measuring machines as well. They organize the storage of tools and accessories and make them easily accessible, while reducing the risk of accidental damage, ultimately extending the service life of the equipment.

Support rails either 500 mm, 600 mm, or 700 mm long are designed to carry one or more of the new rack modules, which are split into three categories. Several may be combined to provide comprehensive storage when using a mix of probe and sensor technology, as is so often the case when meeting today’s complex quality control requirements. To avoid the need for additional motors or cables, the motion of the CMM locks and unlocks the probe head autojoint to effect exchange. Irrespective of which type of rack is being used, there is no need for requalification after changeover.

The first new category is TSR, a multi-sensor tool storage rack having either 5 or 10 ports, with a cover to protect them as well as the probe interface. The unit is able to house any combination of laser scanners, touch trigger probes, surface finish probes, and extension bars. The flexibility of the system enables seamless adaptation to a variety of inspection tasks and ensures that the optimal tool is used for each part of the CNC cycle, enhancing accuracy and productivity.

Three-port SSR stylus storage racks, on the other hand, are for automatically changing the styli themselves, including those for analogue scanning, making available a selection of stylus configurations and ball tip materials. Thirdly, there is a 3-port MSR module storage rack for holding and exchanging increasingly popular tactile scanning probe modules.
