双螺杆挤出机芯轴
尺寸范围：直径10-120MM/长度500-9000MM
材料：正常情况下选用40CrNiMo，经过特殊处理，采用渐开线形式，在扭矩，扭力，负荷的情况下，可以采用具有良好任性和机械性能的WR15E和WR30材料，其性能参数与进口芯轴等同，但性价比远于进口类产品。在加工过程中严格控制准确度，保证芯轴的加工尺寸。
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.

Rally WR15E is a chromium-molybedenum-vanadium-alloyed steel
Which is characterized by;
-Excellent tensile strength combined with good toughness
-High themal stability,high tesistant to thermal shocks
-Good high-temperature strength
-Good machinability and polishablility
-Excellent through-hardenjing properties
-Good dimensional stability during hardening
40CrNiMo是合金钢中的一种，也称合金钢：
-它是在优质碳素结构钢的基础上，适当地加入一种或数种合金元素（总含量不超过5%）而制成的钢种。
-淬火850度，冷却剂-水.油；
-回火温度600度，冷却剂-水.油；
-钢材退火或温回火供应状态布氏硬度GBW小于等于号269；
