Quick Article About Gage Blocks

The Gage Block is considered as the precision ground and the lapped length measuring standard. This tool is used as the reference for the setting of measuring equipment that used in machine shops like sine bars, micrometers, dial indicators and calipers. Besides, it is made as a precisely formed tool to judge the distances between opposing faces.

Moreover, this tool is used for transferring the dimensional values from the state length standard the manufactured article. The use of Gage Block can ensure the standardization of measuring instruments that used in the machine building. It is also used for checking the tooling in checking and measurement devices, for establishing the methods of measuring nominal dimensions, and in adjusting tool machines and fixtures and performing layout work.

There are several types of Gage Blocks that available today. The types include square, angle, rectangular, and wear. The square does not come with a central hole and it is held together with external holder. The angular is manufactured to the precise angle to gage the angles or to check the angle gages and protractors. The rectangular has one or more centrally located to mount on holding bars. The wear is used on the ends of the stack of Gage Block which contacts the parts or variable gages being evaluated.

This tool comes in a set of some gages and accessories that packaged into a kit generally in a case with the adjusting tools. Sometimes the tool kits contain the alternate extension and contact tips, bases, holders, and standards. The measurement unit for this tool can be either metric or English. Some are configured for measuring both.

In addition, this tool is manufactured to precise gage-maker tolerance grades to calibrate, check, and set the fixed and comparative gages. The square, rectangular, scribing, wear and angle types can be found in the carbide, hardness steel, and ceramic materials. The other proprietary blocks may be available for the specific applications with higher or lower tolerances and configurations.

One of the most popular Gage Blocks that you can find on the market today is delivered by MItutoyo. All of the tools from Mitutoyo can meet or exceed all known specifications. The flatness and parallelism surface finish is necessary for achieving the required accuracies that are the same as or better than government requirements.

A certificate of inspection is furnished with all Mitutoyo products with a serial number on the case and an identification number on each block. The deviation of each block is registered. For this inspection, each tool is measured relative to the upper level master using a comparator. The Grade K gauge blocks are manufactured by the absolute measurement using an interferometer. The gauge block set and discrete gauge block are supplied with a certificate of calibration. The certificate of calibration can specify the deviation from the nominal length.
