How to Choose the Best Gage Blocks & Accessories
Understanding Gage Block Materials
- Steel: The most common material, steel gage blocks offer excellent stability and durability. They are typically hardened and ground to precise dimensions. However, steel is susceptible to rust and requires careful maintenance and oiling.
- Ceramic: Ceramic gage blocks are highly resistant to corrosion and wear, making them ideal for environments where rust is a concern. They are also less affected by temperature changes than steel, contributing to greater measurement stability.
- Carbide: Tungsten carbide gage blocks provide exceptional hardness and wear resistance, outperforming both steel and ceramic. They are also dimensionally stable and non-magnetic, but they can be more brittle.
Key Features to Consider
- Accuracy and Tolerance: Gage blocks are graded according to their accuracy. Common grades include AA (reference standards), A (inspection), and B (workshop). The required accuracy depends on the application.
- Set Size and Configuration: Sets vary in the number of blocks and their sizes. Consider the range of measurements you need to perform. Some sets are designed for specific tasks, while others offer a broader selection.
- Accessories: Essential accessories include holders, clamps, and measuring instruments like micrometers and calipers that work in conjunction with gage blocks. Ensure compatibility with your chosen blocks.
Maintenance and Care
- Proper cleaning and oiling are crucial, especially for steel blocks, to prevent corrosion and maintain accuracy.
- Store blocks in their protective cases to prevent damage and contamination.
- Handle blocks with care to avoid nicks or scratches that can affect their precision.
Frequently Asked Questions
What is the difference between gage block grades?
Gage block grades indicate their accuracy and intended use. Grade AA is for the highest precision calibration, Grade A is for inspection, and Grade B is for general workshop use where slightly less precision is acceptable.
How do I choose the right size set?
Consider the range of measurements you commonly perform. A set with a good selection of standard metric or imperial sizes will cover most applications. You can also supplement a smaller set with individual blocks as needed.
Are ceramic gage blocks worth the extra cost?
Ceramic blocks offer superior resistance to corrosion and wear, and better thermal stability. If your work environment is harsh or requires extremely stable measurements, the investment can be justified by their longevity and reduced maintenance.
What accessories are essential?
Essential accessories include holders to create measuring assemblies, and cleaning supplies like lint-free cloths and a suitable oil for steel blocks. Compatibility between blocks and accessories is key.
How often should gage blocks be recalibrated?
Recalibration frequency depends on usage and the required accuracy. For critical applications, annual recalibration is common. For less demanding use, a less frequent schedule may suffice, but regular checks are always recommended.
