What is block gauge
block gauge. This is a commonly used standard tool.
A gauge high in precision and it’s the meter standard to other measuring
tools in the industrial use.
The material varies from steel, ceramic and sizes from 0.5mm to 1000mm.
Precision varies from four types, which are level K, level 0, level 1 and level 2.
| Level | Usages | |
| K | For ultra-precision Measurement | To confirm standard block gauge • For precision academic research |
| 0 | For precision measurement | To check the block gauges of working and inspection use • inspect the precision of measuring tools |
| 1 | For standard measurement | To inspect precision of the gauge • inspect parts of the machine |
| 2 | For working measurement | To adjust precision of measuring tools • install the tools and cutlery |
Assemble block gauge (linking)
 |  |  | |||
01 | First, cross pile up tightly together. | 02 | Slightly turn the two tight combined block gauges to the same direction. | 03 | Ensure that it links together tightly. |
length. For bigger size block gauge, take two block gauges, set it at
cross-shape and turn it to so the measuring face links together.
For bigger size and smaller size block gauge to link together, pile up the
measuring face and slightly slide it back and forth for tight linking. The same
procedures should be followed for smaller size block gauge linking.Main points of linking
To avoid accumulative amount of block gauge’s margin tolerance,
use only minimum amount of block gauge when linking.
Note the average temperature after block gauge linking.
Store and use precautions
- Ensure both sides of block gauge are clean without any burrs. (Use optical flat for checking is recommended.)
- Apply anti-rust oil for storing and keep it at a place with small changes in humidity and temperature.
