Pierced holes bolts1. Purpose: To bolt pierced through.2. request-Position hole tolerance: Need exactly the same threaded holes with sheet or peelplates and sheets under sire is high.225-Tolerances on dimensions diameter: do not need high because notjoin the Assembly. But need to ensure bigger diameter bolts, to easeeasily removable bolts.-For example: Ø10 (mm) bolt, select Selection level of precision of the hole is 15distributed domain D > tolerance of diameter hole from 10.04 ÷ 10.62 (mm).3. The method of machining: drilling.b) requirements for bearing-For 2 sides exposed to the male mold clamping plate and the casing bottom, requiresparallel to high, relatively good gloss. So, when the mount will notexposed.-Rough Milling: machining method + essential.-For 4 sides around not using to assemble so dualsong and do not need high gloss.-Rough Milling: machining methods.
