style="text-indent:25px">周轉(zhuǎn)箱模具成形磨削可用光學投影曲線磨床，或帶有縮仿、修打砂輪機構(gòu)的平面磨床，也可在精密平面磨床上采用專用成形磨削工具磨削。坐標磨床可用于周轉(zhuǎn)箱模具的精密定位，以保證精密孔徑和孔距。也可用計算機數(shù)控(CNC)連續(xù)軌跡坐標磨床磨削任何曲線形狀的凸模和凹模。型腔模多用仿形銑床加工、電火花加工和電解加工。將仿形銑加工與數(shù)控聯(lián)合應(yīng)用和在電火花加工中增加三向平動頭裝置，都可提高型腔的加工質(zhì)量。電解加工中增加充氣電解可提高生產(chǎn)效率。周轉(zhuǎn)箱模具選材是整個周轉(zhuǎn)箱模具制作過程中非常重要的一個環(huán)節(jié)。確定成型方法，采用直壓法、鑄壓法還是注射法。北京通用周轉(zhuǎn)箱模具</p><p

style="text-indent:25px">高碳工具鋼因其熱處理變形大，只適用于制造尺寸小、形狀簡單的成型零件。隨著塑料工業(yè)的發(fā)展，塑料制品的復(fù)雜性、精度等要求愈來愈高，對雙色周轉(zhuǎn)箱注塑模具材料也提出更高要求。對于制造復(fù)雜、精密與耐腐蝕性的塑料模，可采用預(yù)硬鋼（如PMS）、耐蝕鋼（如PCR）與低碳馬氏體時效鋼（如18Ni-250），均具有較好的切削加工、熱處理與拋光性能及較強度。此外，在選擇材料時還須考慮防止擦傷與膠合，如兩表面存在相對運動的情況，則盡量避免選擇組織結(jié)構(gòu)相同的材料，特殊狀況下可將一面施鍍或氮化，使兩面具有不同的表面結(jié)構(gòu)。北京通用周轉(zhuǎn)箱模具</p></p><br
