Accuracy Standards

Dimensional allowance of X, Y and Z

Minimum dimension among X, Y and Z (mm)(thickness) Maximum dimension among X, Y and Z (mm)(length)
20 or more and up to 200 More than 200 and up to 300 More than 300 and up to 500
10 or more and less than 20 Dimensional tolerance  Min. 0.02
20 or more and up to 100 Dimensional tolerance  Min. 0.03 Dimensional tolerance  Min. 0.04
More than 100 and up to 200  

・- Dimensional allowance is based on your specification. Please specify within the limit of the dimensional tolerance shown in the upper table.
- Dimensional tolerance = dimensional allowance upper limit- dimensional allowance lower limit
- Dimensional allowance is specified in units of 0.01mm.

Squareness

Minimum dimension among X, Y and Z (mm)(thickness) Maximum dimension among X, Y and Z (mm)(length)
20 or more and up to 200 More than 200 and up to 300 More than 300 and up to 500
10 or more and less than 20  0.01 0.01
20 or more and up to 100 0.015 0.02
More than 100 and up to 200  

Note) Larger area in two planes at right angles is regarded as datum plane in the case of squareness.
