Thread Check 3-Wire Thread Measuring System
Details:
*Micrometer sold separately.
Thread Check's 0-1" micrometer stand for the 3-Wire Thread Measuring System makes thread and outside diameter measurement fast and easy. The micrometer stand is ideal for holding a micrometer and supporting the part or gage to be measured. The stand features a vertically adjustable platform for positioning and supporting parts and thread plug gages between the anvils of the micrometer. A locking clamp holds a micrometer firmly in place. The micrometer stand features an exclusive "U" track for maintaining wire holders in the ideal position for engaging the lead angle of a thread. The base assembly provides stable and repeatable measurement.
Thread Check, Inc. offers the 3-Wire Thread Measuring System for fast and accurate thread measurement on a variety of measuring instruments.
The traditional three-wire method is the most accurate method of measuring the effective or pitch diameter of an external screw thread. Unfortunately in the past, holding and correctly positioning three wires against a thread while simultaneously taking an accurate measurement had been an extremely difficult task. Now, Thread Check's 3-Wire Thread Measuring System provides a simple and precise way for determining the pitch diameter for threaded parts and thread plug gages. Thesystem enhances Repeatability and Reproducibility ( R & R ) and reduces measurement time to a fraction of the time normally taken using the traditional three-wire method.
Thread Check offers specially designed wire holders and wires, base assemblies, and vertically adjustable off-set platforms that make thread measurement fast and accurate. Thread Check's holders are fitted with certified fulllength thread measuring wires that meet or exceed the requirements of the ASME/ANSI B1.2, and B1.16M, threadstandards as well as Federal Spec. GGG-W-366b and ISO standards. All wire holder sets include the actual wire size, NIST traceable number, and the constant required for determining the pitch diameter.
Thread measuring holders are precision made to predetermined thread pitches. Thread measuring wires are held in a predetermined position by light pressure clips. The holders rotate freely on the spindle/anvil of the measuring instrument so as to engage the lead angle of a thread. Holders for finer pitches have wires positioned off center to allow for measurement at the back of a thread and closer to the shoulder of certain parts. Holders can be purchased without wires for companies that have existing wires. Wires can be easily installed. Thread measuring holders are available in a full range of Standard, Metric, and Acme sizes. Thread Check's engineering department can design wire holders for multiple start threads, helical gears, worms, and other special thread measurement applications.
Applications:
- Certify setplug gages & working thread plug gages
- Monitor the wear on workingthread plug gages
- Monitor and control pitch diameter variation during thread fabrication
- Use in conjunction with "GO" and "NOGO" ring gages to control thread size to the most demanding specifications
- Determine out of roundness and taper that may exist in threaded parts
- Applications for preplating & postplating thread measurement
- Eliminate the cost and time involved in using outside calibration services
- Reduce measurement time to a fraction of the time normally taken using the traditional three wire method
