精研和超精研都是鋼球的終加工工序，高于G40級(jí)的鋼球加工一般要采用超精研工序。鋼球的**終尺寸偏差、幾何精度、表面粗糙度、表面質(zhì)量和燒傷等各項(xiàng)技術(shù)要求，要達(dá)到精研或超精研工序工藝規(guī)程的規(guī)定。 </p> <p> 檢查鋼球的直徑偏差和幾何精度時(shí)，必須在規(guī)定的**儀器上測(cè)量。精研后的工件表面粗糙度和表面質(zhì)量檢驗(yàn)，一般采用在散光燈下目檢。若有爭(zhēng)議，可在90倍的放大鏡下檢查，并與相應(yīng)的標(biāo)準(zhǔn)照片相對(duì)照。超精研后的工件表面質(zhì)量和表面粗糙度的檢驗(yàn)，必須抽取一定工件數(shù)量在90倍的放大鏡下和標(biāo)準(zhǔn)照片對(duì)照檢查。表面粗糙度目視有疑問(wèn)時(shí)，可在表面粗糙度儀上進(jìn)行檢測(cè)。 </p><p> 影響鋼球質(zhì)量的因素： </p> <p> 鋼球材質(zhì)會(huì)產(chǎn)生影響：鋼球、鑄鐵球、合金鋼球等，不同材質(zhì)的密度不同，鋼的密度比鑄鐵的大，合金鋼則依主要合金元素的密度及含量不同而不同。 </p> <p> 鋼球的制造方法會(huì)產(chǎn)生影響：軋制及鍛打的鋼球其組織致密，故密度大，鑄造的鑄鋼球、鑄鐵球或鑄造合金球等的組織致密，相對(duì)密度小一些。 </p> <p> 鋼球金相組織會(huì)產(chǎn)生影響：馬氏體、奧氏體、貝氏體、鐵素體等不同晶體結(jié)構(gòu)下密度也不相同，對(duì)結(jié)晶細(xì)度也有影響。鋼球可以用在汽車(chē)安全帶里。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

</p> <p> 中頻加熱：常用頻率為（2500～8000）HZ，淬硬層深度為（2～10）mm。 </p> <p> <br /> </p> <p> 工頻加熱：電流頻率為50HZ，不需要頻設(shè)備，城市用交流電即可，硬層深度為（10～20）mm以上，城市用交流電即。 </p> <p> 鋼球感應(yīng)加熱優(yōu)缺點(diǎn)：感應(yīng)加熱表面淬火加熱速度快，生產(chǎn)率高，加熱溫度和淬硬層深度容易控制，鋼球表面氧化和脫碳少，鋼球變形小，可以使全部淬火過(guò)程實(shí)現(xiàn)機(jī)械化、自動(dòng)化。鋼球通過(guò)酸洗后，金屬表面得到鈍化，形成保護(hù)膜，從而能提高鋼球的抗腐蝕能力。上海專業(yè)鋼球***的選擇</p><p style="text-indent:25px">按照用途分類(lèi)，鋼球可以分為：靜音鋼球、軸承球、特種鋼球等。上海專業(yè)鋼球咨詢客服</p><p> 不銹鋼珠性能：硬度達(dá)到56—58度，有磁性，耐腐蝕性好，耐磨性和韌性強(qiáng) </p> <p> 不銹鋼珠應(yīng)用：鋼珠金屬磨料的一種，主要品種有不銹鋼丸、鑄鋼丸、鋁丸、鋼絲切丸、研磨丸、銅丸，鋼珠廣泛應(yīng)用于有色金屬壓鑄件、澆鑄件，鋁型材、汽車(chē)零部件、機(jī)械制造業(yè)、五金、泵閥行業(yè)的表面處理。主要集中于去產(chǎn)品表面氧化皮、邊緣表面毛刺、表面粗糙化、亞光郊果、平整強(qiáng)化、除銹處理。 </p> <p> 鋼珠：鋼珠主要用于高要求高亮度的鋁合金，不銹鋼等產(chǎn)品拋光。鋼珠分不銹鋼和研磨碳鋼兩種，不銹鋼鋼珠使用很方便，無(wú)須防銹，碳鋼鋼珠許要防銹！ </p> <p> 應(yīng)用領(lǐng)域：不銹鋼拋光球通常用于各種五金件的去毛疵及拋光，從而使工件達(dá)到光滑光亮的效果：銅件、鋁件、銀器等等。另外鋼球也可以用來(lái)研磨藥材、化工原料。 </p> <p> 特性：任何一種鋼球均可用來(lái)拋光，但具體選用哪種材料哪種規(guī)格要根據(jù)工件的尺寸、形狀及性能來(lái)確定，通常拋光球選用4MM不銹鋼球。上海專業(yè)鋼球咨詢客服</p><p
