China Hardened Steel Blocks 0.0001" Precision Matched Machinist

size : 3-300mm

material Gcr15

Package : plastic box or plywood case box ,also can accet the customer required.

The measuring block is a measuring instrument with rectangular or circular cross section and accurate size between two parallel measuring planes.

The main features of gauge block :

simple shape, stable value, good abrasion resistance and easy to use. In addition to each block can be used as a specific value,

it can also be combined into a variety of different sizes required for use.

Two a gauge with an exact dimension and a rectangular or square cross section between parallel planes.

The two parallel plane is called the measuring plane.

The measurement surface is very flat and smooth (its surface roughness value Ra is less than 0.016 micron),

so it has good cohesiveness: after one measuring block and another measuring plane are pushed together.

Using this characteristic, different sizes of measuring blocks can be combined.

For example, 91 sets of measuring blocks can form any size between 2 and 100 millimeters in microns.

The gauge blocks are usually made of bearing steel, the thinnest ones are generally 0.5 millimeters,

and the thickest ones are 1000 millimeters.
Function :

1, as a standard of length, transfer the size value.

2. It is used to verify the indication error of measuring mouth.

3. As a standard part, the workpiece size is measured by comparative method,

or the zero position of measuring instruments is calibrated and adjusted.

4. It is used for directly measuring parts size.

5. It is used for precise machine tool adjustment and precise marking in machining.
