a. the hole pierced boltsPurpose: To bolt pierced through.Requirements:Tolerances: hole location precision or Need an plate with threaded hole in shell plates that are high.Tolerance of diameter size: do not need high because not to join the Assembly. But need to ensure bigger diameter bolts, to easily removable bolts.For example, Select the select level Ø10 (mm) bolts of the hole is 15 D tolerance distributed domain > the real diameter of holes from 10.04 > 10.62 (mm).Method of machining: drilling.b mounting Hole positioning loops.Purpose: insert the locating ring.RequestHole position tolerance: an perforated silver spray high stalk.Size tolerances: for when fitting the ring positioned on is not too tight or too loose. And when fitted should ensure the sealed level to position the loop is inserted firmly. But avoid excess levels too large damage positioning loops.For example, select the positioning ring Ø40 (mm) pick the exact level of the hole is level 5 distributed domain tolerances P, infer the diameter of the hole is 39979 ÷ 39985 (mm)Method of work: a rough Milling milling + essential.c. mounting Hole spray stem silverSimilar mounting hole positioning loops.d. requirements for clamp-on plateFor both sides on the bottom and sides (work) requires the right high gloss. And parallel of the 2 sides together, parallel of the underside and the top of the mold is high. To not open at docking.Method of work: a rough Milling milling + essential.As for the 4 sides without docking, so shiny and parallel don't need high.Rough Milling: machining methods.
