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||Classification of Standard Dimensions||Tolerance|
|Dimensional tolerances for length dimensions, excluding chamfered parts||m||Medium||Equal to or greater than 0.5, equal to or less than 3||±0.1|
|More than 3, equal to or less than 6||±0.1|
|More than 6, equal to or less than 30||±0.2|
|More than 30, equal to or less than 120||±0.3|
|More than 120, equal to or less than 400||±0.5|
|More than 400, equal to or less than 1,000||±0.8|
|More than 1,000, equal to or less than 2,000||±1.2|
|Dimensional tolerances for length dimensions of chamfered parts||c||Rough||Equal to or greater than 0.5, equal to or less than 3||±0.4|
|More than 3, equal to or less than 6||±1|
|More than 6||±2|
*General tolerances for JIS B 0405 cutting are used.
|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.)|
Dimensional Changes for Clear Resin
Unlike metal, resin is a material that easily deforms as a result of temperature and humidity and changes in dimensions. Accuracy is assured in the following way:
- Testing is conducted in a temperature- and humidity-controlled environment
- Accuracy assurance is based on the results of inspections performed immediately before shipment.
