Mitutoyo MiStar 555 CNC CMM Available with PH20 Probe

Mitutoyo America Corp.’s MiStar 555 CMM with the PH20 5-axis probe system is designed to provide enhanced measuring capability, increased feature access and a threefold throughput improvement.

The system combines the MiStar three-sided open architecture, wide accuracy-guaranteed temperature range, environment-resistant absolute scale and all-in-one space-saving design for an improved coordinate measuring machine, the company says.

The CMM features enhanced measuring capability with probe head touches. The company says the rapid rotary motion of the PH20 head enables measurement points to be taken faster and with improved accuracy, repeatability and time savings.

The system’s 5-axis provides increased feature access with infinite probe angles. This infinite positioning is said to guarantee optimal feature access, minimizing stylus changes, thereby improving usability over fixed angled probe heads. The 5-axis motion also enables larger part access on the CMM by minimizing space required around the part for probe orientation.

According to the company, the CMM also offers a reduction in calibration time. The inferred calibration technique developed for PH20 determines the head orientation and probe position in a single operation, enabling subsequent measurement at any head angle. Further, modules only require a few touches on the calibration sphere before use.

Users of the PH20 probe head will immediately have access to the range of TP20 probe modules, providing a wide selection of trigger forces, directional sensing options and extensions to meet application requirements. The detachable modules provide crash protection and can be automatically changed using the TCR20 change rack. The TP20 EM2 probe module enables holes greater than 300 mm diameter to be measured without CMM motion.
