MATERIAL: A6061 T6材料：A6061 T6 ENCLOSURE MADE FROM SOLID MODEL, NOT FROM THIS PRINT. THIS PRINT IS FOR SECONDARY MACHINING AND MOLD VERIFICATION ONLY. ALL DIMENSIONS IN PARENTHESIS ARE REFERENCE DIMENSIONS. DIMENSIONS ENCLOSED ARE INSPECTION DIMENSIONS;腔体均由实体模型转换得来。此图纸仅限于二次机加工和模型尺寸校核之用。括号尺寸为参考尺寸;圈出来的尺寸为检测尺寸; UNLESS OTHERWISE SPECIFIED, TOLERANCE PER NADCA, TITLE BLOCK FOR REFERENCE未注公差请见NADCA标准，标题栏内为辅助参考 DETAIL CORNERS AND CHAMFERS REFER TO SOLIDWORKS MODEL; OTHERS REFER TO TITLE BLOCK;导圆倒角具体参见SOLIDWORKS模型;其余参见标题栏，默认为0.3mm; SURFACE FINISH MUST BE 3.2 FOR ALL MARKED JOINT SURFACE; SCREWED SURFACE MUST BE 3.2; OTHERS REFER TO TITLE BLOCK;所有标注的隔爆面的表面粗燥度一律为3.2;螺纹面光洁度必须为3.2;未注表面粗燥度参见标题栏; COMMON REQUIREMENTS ACCORDING TO NADCA;一般压铸要求根据NADCA标准 3 mm MINIMUM WALL THICKNESS REQUIRED UNDER AND AROUND ALL HOLES IN PRESSURIZED WALLS;NO ADDITIONAL HOLES OR MACHINING ALLOWED所有承压壁上的孔的周围金属厚度最小3 mm;不允许有设计之外的孔和机加工 REMOVE ALL BURRS AND ALL SHARP EDGES去除所有毛刺和锐边 EXCEPT AS NOTED ON DRAWING,SIDE COVER FINISH IS CLEAR IRIDITE; EXTERIOR SURFACES EXCEPT FOR JOINT SURFACE AND MATING SURFACE COATED WITH POWDER;COLOR: RAL 1007; DETAIL REQUEST REFER TO PAINTING DOCUMENT ATTACHED;侧盖表面处理除了图中特别标明外，均需做表面硬化，防锈防腐处理；外表面除了隔爆接合面和配合面以外须做喷粉处理，侧盖外表面喷粉色号：RAL 1007;喷粉要求参见附带喷涂文档; AFTER MACHINING, PART MUST WITHSTAND MIN. 1.5MPa HYDROSTATIC TEST, HOLD FOR 60 SECONDS . NO DAMAGE AND PERMANENT DERFORMATION LEADING TO FLAMEPROOF FAILURE;机加工后零件必须进行最小1.5MPa水压实验，历时60秒，以无损坏和影响隔爆的永久变形为合格; WORDS ON THE COVER. FONT: GE INSPIRA PITCH,SIZE: 14,; LETTERS AND ITS POSITION REFER TO SOLIDWORKS MODELS;盖子表面的压铸字母，字体：GE Inspira Pitch,字号：14;字母及其位置参见三维模型； * MARKED AREAS ARE FLAMEPROOF JOINTS. CASTING BUBBLES BIGGER THAN 0.4MM ARE ALLOWED ONLY WHEN (

1) LENGTH/DIAMETER OF SUCH BUBBLES MUST SMALLER THAN 0.6mm; (2) TOTAL LENGTH OF BUBBLES IN ANY DIRECTION MUST BE LESS THAN 1mm; (3) MAX. AMOUNTS OF SUCH BUBBLES IN EACH FLAMEPROOF JOINT MUST LESS THAN 3; (4) BETTER TO CONTROL THE BUBBLES LOCATED IN THE END OF THREADS; *号标记的地方为隔爆面，允许出现0.4mm以上尺寸的砂孔；前提是(1)必须控制单个砂孔长度/宽度/直径小于0.6mm;(2)任意直线方向上所有砂孔加起来的总长度不超过1mm;(3)任意一个图示隔爆面上砂孔数量小于3个；(4)砂孔分布位置最好能控制在螺纹的根部； FOR NONE-JOINT SURFACE, CASTING BUBBLES SHALL BE NOT OVER 2.4mm WIDE AND NOT OVER 1.6mm DEEP; THESE HOLES SHALL NOT AFFECT THE MIN. THICKNESS;非隔爆面上，砂孔的长度/宽度/直径不能超过2.4mm,深度不超过1.6mm;砂孔不可影响最小壁厚； CASTING BUBBLES MUST BE INSPECTED 100%FOR EVERY PIECE OF PARTS;必须100%检测每一成品件的砂孔;
