WHY SPENDING MONEY ON A PRECISE GAGE BLOCK IS WORTH IT

An accurate and precise gage block is a necessity when it comes to setting up a comparative measuring device. It is key to use a gage block that will properly match the desired size; however, purchasing a specific gage block can be costly. Although these costs can be intimidating, they should not be avoided or worked around.

Specialized gage blocks reap a handful of benefits, including:

When all three of these benefits are combined confidence in measurement results are guaranteed.

WHAT TO AVOID

Although standard gage blocks are a great deal cheaper than those specially made, the cheaper route should ways be avoid. Many individuals think there are ways to move around having to buy a specially made gage block, however this idea is very very wrong. For example, buying a low cost gage block and modifying it to a desired size is NOT a solution. Grinding a gage block to a smaller size is a shoe-in for inaccuracy. When the original shape of a gage block is reduce, the overall hardness, stability and geometry of the block becomes unreliable. Wringing of standard gage blocks is also a poor idea.

Similarly to grinding, wringing gage blocks reduces the overall stability of the block; therefore, making it unreliable and inaccurate.

Another major reason to avoid taking the cheaper route and modifying a block yourself has to do with calibration. Gage blocks, like all measuring instruments, need to be recalibrated frequently. If a gage block is modified, it is no longer considered a master block; therefore, many calibration companies and labs will not be able to perform calibrations necessary. This means that the gage block can’t be deemed for sure as accurate or reliable.
