Debut Exhibition of Actual XYZAX Opt-BLISK at JIMTOF 2022
Non-contact blisk measuring machine XYZAX Opt-BLISK

Tokyo Seimitsu Co., Ltd. will exhibit the actual machine of our newly-developed Non-contact Blisk Measurement Special-Purpose Machine, or XYZAX Opt-BLISK, for the first time at the 31st JAPAN INTERNATIONAL MACHINE TOOL FAIR (JIMTOF) 2022 scheduled to be held in Tokyo Big Sight from November 8 (Tuesday) to 13 (Sunday) this year.

The demand for measurement of “blisks," a component of aircraft engines formed by the integration of rotor disc and blades is rising year by year. Sensors and styli able to reach the detailed portions where blades overlap are essential for measuring blisks, and contact-type sensors have played a role in such measurement until now. While a wide variety of styli can be attached to a contact-type sensor for flexible measurement, it is necessary to consider the deflection of the stylus caused by measurement pressure and friction, as well as the measurement speed from the sharp shape of the blade edge, therefore reducing measurement time is a major challenge.

In light of this, our company developed a non-contact blisk measuring machine, XYZAX Opt-BLISK by combining technologies cultivated in the development of its CMM and non-contact, high-accuracy rotating probe.
XYZAX Opt-BLISK's unique measuring path generation technology and 4-axis synchronization control of the XYZ axis and rotating probe enable non-contact and high-speed scanning along optimal paths whilst maintaining sensitivity, even in blisks with narrow portions where blades overlap. By combining XYZAX AXCEL, a high-acceleration CMM, with a non-contact, high-accuracy rotating probe, measurement time has been reduced by approximately 60% compared to conventional contact-type sensor measurement.

We would like you to take a look at our new machine with your own eyes at JIMTOF 2022.
