What material are gauge blocks made of?

A variety of materials are used for the construction of gage blocks, with steel alloys and carbide (either chromium or tungsten) being the most common. However, ceramics and even glass are used in special applications.

What type of steel are gauge blocks made of?

Gauge blocks are usually made either from hardened alloy tool steels, ceramics or cemented carbides (such as tungsten carbide or tantalum carbide). Often the carbide has a hardness of 1500 Vickers hardness.

What are the different grades of gage blocks?

There are 4 tolerance grades; 0.5, 1, 2, and 3. Grades 0.5 and 1 gauge blocks have lengths very close to their nominal values. These blocks are generally used as calibration masters. Grades 2 and 3 are of lower quality and are used for measurement and gauging purposes.

What is the best grade of gauge blocks?

A. Grade 0, Webber A1: The most popular grade of blocks: 1) it is accurate enough to perform 95% or more of all applications. This grade is recommended for general use. 2) most steel blocks are Grade 0, and steel is the most popular choice of gage block materials.

Which is the material the slip gauge are manufactured?

Tungsten Carbide is very dense material. This allows the production of high quality surface giving superior wringing quality to the Slip Gauges. Tungsten Carbide is highly resistant to wear. The slip gauge will retain its accuracy for a long time.

What makes gauge blocks stick together?

The source of the forces holding gage blocks together are thought to come from: Air pressure from the surrounding environment as the air is squeezed out when the blocks are slid together. Surface tension from oil that remains on the gage blocks or water vapor from the air that acts as an adhesive to hold them together.

How often should gauge blocks be calibrated?

every 1 to 3 years
2) HOW OFTEN SHOULD GAGE BLOCKS BE CALIBRATED? Industry consensus is that gage blocks be calibrated every 1 to 3 years. Calibration intervals may be shortened or lengthened as needed. The frequency of calibration is determined by the user with consideration given to usage, care, and desired accuracy.

Why do gauge blocks have holes?

The primary purpose of the hole is to allow tie rods and screws through the center of the blocks, so that combinations can be semi-permanently fixed together. The hole also forces the user away from the center of the block, so that any wear on the block is more uniformly distributed.

Which material is used to clean the slip gauge?

This Process is very useful to produce a required size by assemble several gauge blocks. Before wringing of blocks; wipe them clean using a cloth, chamois leather, or a cleansing tissue.

2) HOW OFTEN SHOULD GAGE BLOCKS BE CALIBRATED? Industry consensus is that gage blocks be calibrated every 1 to 3 years. Calibration intervals may be shortened or lengthened as needed.
