Shaft parts should use different materials and different heat treatment specifications (such as quenching, normalizing, hardening, etc.) in order to obtain a certain strength, toughness and wear resistance depending on the operating conditions and requirements. After quenching cheap price (or normalized) price after the precision shaft parts, 45 steel shaft parts are commonly used materials. Get better cutting performance, but also to obtain high strength and toughness, and other mechanical properties, surface hardness after quenching up to 45 ~ 52HRC. 1. Technical requirements and CA6140 lathe spindle lathe spindle function CA6140 stepped precision spindle shaft parts wholesale, on which there is mounting support bearings, cylindrical, conical surface transmission parts, install the sliding gear spline, installation chuck and top inside and outside the cone surface coupling nut screw fastening surface, deep hole and so on through the bar. The following describes the main parts of the spindle, and technical requirements: ⑴ two spindle bearing journal bearing journal A, B roundness tolerance of 0.005mm precision shaft parts technology, runout tolerance of 0.005mm; and bearing journals 1:12 tapered surface contact rate of ≥70%; surface roughness Ra of 0.4mm; the dimensional accuracy of the bearing journal is IT5. Because the spindle bearing journal is used to install the support bearings, is part of the spindle assembly datum, so it's a direct impact on the manufacturing precision rotary precision spindle components.
