What's the maximum size of 3 mm thick aluminum sheet?
First look at tolerance taggingIf there is no tolerance, see the accuracy level of the workpiece and check the tolerance listA 3-4 mm deviation is acceptable if the magnitude is not noted and is of no importanceThat is, the 34mm can also be used if lower precision sizes can be addedOnly board class is generally down bias, there is very little difference
To see what is your production process requirements? If it is hot extrusion, the width of the largest flatness requirements under the condition of low at about 300mm. If the processing technology of aluminum strip is hard to say, to see the production capacity of the equipment (the size and size is the maximum size of the majority in the 1.2) to 1.5 meters wide, the length of one hundred meters above
See tolerance taggingIf there is no tolerance, see the accuracy level of the workpiece and check the tolerance listA 3-4 mm deviation is acceptable if the magnitude is not noted and is of no importanceThat is, the 3.5mm is OK, if the lower accuracy is generally 2.95
