    Why Don’t I Input a Coupling Diameter?

    Tolerances for shaft alignment are typically expressed in terms of angle and offset. It is common knowledge that offsets cause confusion, but angularity often confuses those tasked with aligning or verifying alignments.

  • Using the Verti-Zontal Process on Wind Turbines with Adjustable Chocks

    Using the Verti-Zontal Process on Wind Turbines with Adjustable Chocks

    The adaptive user interface will guide you throughout the measurement and alignment process. We are especially proud of the function – VertiZontal Moves™ – where you only have to measure once before making the required vertical and horizontal adjustments. Quite a time conserver in a time strained maintenance world!

    Coupling Tolerances vs. Shaft Alignment Tolerances, revisited

    There were huge differences between coupling alignment tolerances and precision shaft alignment tolerances during a recent Acoem RT-300 training class. Electric motors and centrifugal pumps fitted with grid couplings of model 1070T were aligned at 1800 RPM. A contractor performed the initial alignment on this fairly new installation.

  • Phase Analysis for Confirmation of Machine Faults

    Phase Analysis for Confirmation of Machine Faults

    Verifying your machines' issues using phase analysis can be a very effective method of verifying faults discovered during an inspection. Vibration programs can be made more effective when phase, particularly cross-channel phase analysis, is applied properly.

    Do You Know the Incredible History of Machining?

    The machine tool industry has been around for a long time and it is exciting to see how the industry continues to thrive and incorporate new technology and processes. What do you think the future might hold for this industry?

  • 5 Things You Need to Know if You are New to the Machine Tool Industry

    5 Things You Need to Know if You are New to the Machine Tool Industry

    The machine tool world can be overwhelming if you are new to it. You may hear terms like tolerances, CNC, CPK, surface finish, uptime, and cost per part thrown around, and it may seem like a foreign language if you are just starting out in this industry.

  • Meax Level, machinetool measuring

    Top Tips for Leveling Your CNC Machine

    CNC machine leveling is an essential function. Optimizing a machine's capability and producing high-quality parts is a key element of its capability.

    Using the Acoem Bearing Defender as a Lubrication Tool

    There are many tools on the market to use in conjunction with lubrication – mechanic’s stethoscopes, “smart” grease guns which use ultrasonic, or just an ultrasonic tool itself. High-frequency vibration measurements can also do this.

    Coupling Tolerances vs. Shaft Alignment Tolerances, revisited

    We have several times discussed the differences between coupling alignment tolerances and precision shaft alignment tolerances. As stated in those text the coupling manufacture’s tolerances are for the coupling. As maintenance professionals we are concerned with the coupling, however we are more concerned with the bearings in the machines.

  • When selecting a belt, several considerations must be taken into account to ensure proper operation, long belt life, and low maintenance requirements. Belt drives may seem simple in design but many factors are considered when selecting the proper bel

    Belt Drive Basics

    Belt Drive advantages - quiet in operation, require no lubrication, and are relatively cheap to produce.

  • ACOEM Run-out Probe

    Compressor Rod Runout with the NXA Runout Probe

    The NXA Runout Probe is a simple electronic tool designed to detect and measure shaft runout. The new tool represents a unique application of a linear variable displacement transducer (LVDT) to provide an easy-to-use but highly accurate measure of machinery problems that can confound the measurement and correction of shaft misalignment

  • The Value of Document Management for Manufacturing Safety by ACOEM

    Why You Should Always Document Alignment Data

    When everything is running smoothly, digging for the necessary protocols or procedures may feel cumbersome, but doesn’t necessarily set off bells and whistles that a bigger problem may be lurking.
