AMETEK Precitech Inc.KEENE, N.H., April 22, 2010 — Ametek Precitech Inc.’s Part Centering Accessory uses a combination probe and reference surface to align the outer diameter of a vacuum-mounted, round, continuous surface component relative to the rotational axis of the work holding spindle to an accuracy of 2 µm in ≤15 s. The device mounts to the Z-axis tooling plate of a Precitech N250, N250UG, N700 or FF705 with UPx control. The device consumes slightly more real estate than a standard Precitech tool holder; however, it can be mounted in a location at the far end of the work envelope and requires very little X-axis...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...Photonics Spectra March 2023 IssueInertial Measurement UnitsTAC-450 Inertial Measurement Units from Emcore Corp. feature a compact design, robust performance, and survivability to meet the needs of commercial and military platforms.
