Rough shaft parts: selection bar, forgings rough form. For little difference between the outer diameter of the shaft, shaft parts according to the requirements, production type, equipment condition and structure. Generally the main bar; and for the outer diameter of the large difference between the stepped shaft or axle important precision shaft parts, often used in forging, which saves material and reduces the workload of machining, but also to improve the mechanical properties. Rough forging forging and forging the way there are two kinds of freedom. Small batch multi-use free forging shaft parts, according to different production scale. When using a large number of forging mass production. Luoyang Fuyuan various gears Gear Machinery Co., Ltd. specializes in producing bevel gears, shafts, plates, etc., please come to order. 1. CA6140 lathe spindle technical requirements and functions Spindle Lathe CA6140 is stepped on a mounting support bearings, cylindrical, conical surface transmission parts, install the sliding gear spline, installation chuck and top conical surface inside and outside, connecting fastening nut screw surface automotive shafts, deep hole through the bar and so on. 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 mechanical shaft parts, runout tolerance of 0.005mm; and a bearing journal :12 tapered surface contact rate ≥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.
