Composite Sheet processing specifications

General Tolerance Standards for Machining Dimensions

The tolerance for external dimensions is ±1.0. See the table below for the tolerances used for other sections.

Standard Part Tolerance Grade Dimension Tolerance
Symbol Description
Dimensional tolerances for length dimensions, excluding chamfered parts m Medium 0.5 ≦ X ≦ 3 ±0.1
3 < X ≦ 6 ±0.1
6 < X ≦ 30 ±0.2
30 < X ≦ 120 ±0.3
120 < X ≦ 400 ±0.5
400 < X ≦ 1,000 ±0.8
1,000 < X ≦ 2,000 ±1.2
Dimensional tolerances for length dimensions of chamfered parts c Rough 0.5 ≦ X ≦ 3 ±0.4
3 < X ≦ 6 ±1
6 < X ±2
*General tolerances for JIS B 0405 cutting are used.
Standard Value Example
If the internal angles of the model are sharp corners or are less than R3, machining of around R3 will be applied. (If you would like the internal angle to be finished to a sharp corner or to less than R3, contact meviy support for an estimate.) Example

Countersink hole machining finish

Product finish

  • ・Countersunk holes and machined external surfaces will expose the core material.
  • ・Although deburring is performed, the metal surface material may be sharp due to the characteristics of the material. Please be careful when unpacking and handling the product.
  • ・A protective sheet is attached to prevent scratches.
  • *There may be differences in color depending on the shape and surfaces to be processed.
