ALTERA C High-Accuracy CMM Gives You More Accuracy Less Cost

Dec. 9, 2024
LK Metrology's ALTERA C HA CMM is available in 5 sizes and improves on the standard ALTERA C range with better accuracy, stiffness, repeatability, and efficiency.

The ALTERA C HA (high accuracy) inspects components machined to tight tolerances without being hard on your wallet.

Available in five sizes, the ceramic-bridge machines are constructed from the same component parts as the standard ALTERA C range but are optimized to deliver 16% higher accuracy during a measuring cycle, with 13% better repeatability and 50% more accurate scanning. Volumetric accuracy is from 1.3+L/350, repeatability from 0.0013 mm, and scanning accuracy from 0.002 mm.

The spread of the air bearings supporting the main drive leg has been widened to increase the stiffness of the bridge assembly, which is particularly beneficial during high-speed movements. Measuring uncertainty when chasing tolerances down to microns is significantly better. For the same reason, the bearing mountings have been further stiffened and their alignment improved. Due to the increased dynamic forces in play when measuring on the fly, the new design is helpful when using a scanning probe.

The pre-loaded, wrap-around air bearing configuration runs with a reduced air film thickness for low energy consumption and gives repeatable measurement results, even at fast axis speeds. Friction drives provide smooth motion together with exact positioning at continuously varying speeds, as well as zero-backlash and overload protection.

Multisensor capability is provided with the Renishaw PH10M motorized probe head able to deploy a touch-trigger probe, scanning probe, or laser scanner. LK's proprietary, DMIS-based, multi-sensor CAMIO software enables programming and measurement based on 3D CAD data as well as comprehensive reporting.

The five sizes of ALTERA C HA have a measuring envelope above the granite table ranging from nominally 700 x 650 x 500 mm for the smallest CMM up to 1,500 x 850 x 650 mm for the largest.

The machines are compact for the size of their respective measuring volumes and are also fast, accelerating at up to 1,390 mm/s/s for high inspection efficiency.

They are equally at home in an inspection department or on the shop floor, especially as pneumatic anti-vibration mounts can be specified to isolate the CMM from nearby sources of low-frequency vibration, such as large machinery. Maintenance costs are low, and all models carry a 10-year accuracy guarantee covering dimensional stability.
