63 rms maximum surface finish of packing chamber 填料腔表面光洁度最大为63rms 。
Best surface finish is provided by machining methods , especially by grinding 用机械加工方法,特别是磨削方法,可以获得最佳表面光洁度。
Non - rotating stem has close roundness and straightness tolerances and is burnished for a superior surface finish 不旋转阀杆避免了圆度和直度偏差,并且具有相当好的表面光洁度。
Optimum dilution ratios will depend on the actual operation , material , tooling , speeds and feeds , as well as surface finish requirement 实际配比取决于实际工艺、材料、加工刀具、速度以及表面光洁度要求。
It can produce parts and fittings of high precision in measurement , of good surface finish and of complex form as per customersrequests 公司还可按客户的来图要求制造出各种尺寸精度高表面光洁度好形状复杂的配件。
