This spindle should ensure the matching distance of a workpiece hole control. After adding 1 to the same part, the hole diameters are different within the allowable tolerance range. It is recommended to have a side gear spindle to match it to meet the requirement of small spacing. This is in line with the reasonable grading design of the spindle. The following is a set of formulas as a reference for the design of the inner shaft of the graded grinding mill: ) Basic size of the graded core d s-Po+(t - 1) × 6) Limit deviation of the graded core Where: Base size of the lower hole, mm; 41 Filling difference, mm; 1 Mandrel grade number; · Mandrel grade serial number. Example: The gear hole grid 3I17 (\.021) milling core is required to be graded. Requirement: Substituting into formula A, we get formula A2: d1-30+(1 - 1)× d g0=30+(2 - 1)× d a20+(3 d sn=30-(4 - 1) x 2 × 4 = - 0.003 The design size of the graded spindle is: 1 30.000%mct Heavy grade 300G61003 1 grade 30.012Hc3bzxz.net Line 30.0151c JB/T9163.12-1999 2 Grinding and rolling, grading heart Can Shichuan line Na hundreds of tables I AI Heart Chi points the order of special Type civil size 15 000 .n21.000 .21uus 22 000 23 000 ..25 us Pole inquiry Applicable workpiece light Basic rate small Ball size I6 JB/T9163.12—1099 Table A() Spindle cable treatment number 30 011 Spindle diameter Test limit difference Applicable L.
