雙螺桿擠出機芯軸

尺寸范圍：直徑10-120MM/長度500-9000MM

材料：正常情況下選用40CrNiMo，經(jīng)過特殊處理,，采用漸開線形式,，在扭矩，扭力,，負荷的情況下,，可以采用具有良好任性和機械性能的WR15E和WR30材料，其性能參數(shù)與進口芯軸等同,，但性價比遠于進口類產(chǎn)品,。在加工過程中嚴格控制準(zhǔn)確度，保證芯軸的加工尺寸,。

Size:diameteter 10-120mm/length500-9000mm

Material;

(1) 40CrNiMo with special treatment and involute form can be used cicumstances of high torque, high torsion and high load.

(2) And nitrogen bearing Martensite stainless steel,WR15EandWR30 can aiso be spplide to make good toughness and machine performance available.The performance similar to the imported shaft but with more cost efficient,the machining process is under accurate controlling to make sure the accurscy of groove depth and distance,the smoothness of the surface,toughness and durability as well.
