To solve " O " model rubber group upper mould is hard to control concerned dimension and positional public errand to be inscribed this in turning, use dimension conversion law to undertake machining. Obtained favorable result. Diagram of structure of graph upper mould " O " model the structure of rubber group upper mould is shown like plan institute. Its technical requirement is: On, public errand of dimension of D of lower mould diameter is 0.

02mm, "O " model public errand of dimension of diameter of circle cross section is 0.

02mm, after fluctuation model combines a model " O " model position error is less than the face 0.

02mm, be hard to control concerned dimension and positional public errand in turning so. To solve this one problem, use dimension conversion law to undertake machining. Obtained favorable result. Machine a method: First of thick car good mould outside round, stay 0.

The surplus of 5 ～ 1mm, the end panel car of the mould is good; Use what had ground meticulously " O " model encircle good mould of vehicle of figuration knife fine outside round D, measures real measure is D1; Computational figuration knife is transverse and mobile the position measures L, in order to assure the positional dimension public errand of D. L=(D1-d)+Ø(mm)2 arrives to amount to displacement is accurate, use slip gauge and dial gauge to measure. Add man-hour to want to control the feed deepness of figuration knife carefully, when polishing, the attention does not want to cast shape face pointed part. CNC Milling CNC Machining
