Coordinate Measuring Machine

Hexagon Manufacturing Intelligence, North Kingstown, RI, has released a new coordinate measuring machine (SMM) platform. The Global S CMM is part of the company’s Enhanced Productivity Series (EPS) featuring smart technologies such as user experience (UX) enhancements, measurement software, and advanced “green” options. The EPS platform is designed specifically to simplify the creation, execution, and analysis of measurement routines. The Global S CMM platform utilizes PC-DMIS CMM software for the collection, evaluation, management, and presentation of manufacturing data. Leveraging software advancements, common tasks such as the selection of probe tips and importing files are now 3–8 times faster than existing solutions.

Rapid Prototyping System

dSPACE, Wixom, MI, has released a system a compact, real-time system that is ideally suited for rapid control prototyping (RCP) in the lab, including function design, execution, and validation. The SCALEXIO is known for performing hardware-in-the loop simulations, but now the technology can be used for control, validation, and data acquisition tasks for closed-loop real-time applications. Features include state-of-the-art Intel Core i7 processor for high computing power, intelligent I/O network, space for up to 18 I/O boards, bandwidth for handling extremely large data streams, and options for customized FPGA boards in combination with I/O plug-on modules.

Self-Aligning Ball Bearings

Lubricating stainless steel and self-aligning linear ball bearings are available from LM76, E. Longmeadow, MA. Pillow blocks and flange blocks feature a lubrication fitting and an alignment set screw in the pillow blocks and flange blocks. Stainless steel and self-aligning linear bearings are modified by having an alignment flat ground on the bearings’ outer shell and drilling a hole through the outer shell. Lubricants can then be pumped directly inside of linear ball bearing races without having to remove the bearing from the shaft. The pillow blocks are available in closed single and double bearing models for inch-sized shafts from 0.5 to 2 in., and the flange blocks are available in single- and double-bearing models for inch-sized shafts from 0.5 to 1.25 in.
