Such steel quenched and quenched, 40Cr alloy structural steel for medium-speed and high precision shaft parts. Has good mechanical properties. Appearance of hardness up to 50 ~ 58HRC and has high fatigue resistance and good wear resistance, after bearing steel and spring steel 65Mn GCr15 quenched and surface induction hardening. Axis can be manufactured with high accuracy. Luoyang Fuyuan various gears Gear Machinery Co., Ltd. specializes in producing bevel gears, shafts, plates, etc., please come to order. ⑸ threaded spindle error on the face of the spiral is one of the causes compression nut face runout, it should control the precision of the thread. When the compression nut on the spindle runout is too large, will be pressed rolling bearing inner ring is tilted axis, thus causing the spindle radial runout. 2. The main problem points and measures Spindle machining process is how to ensure the spindle bearing journal of the size, shape, location accuracy and surface roughness of the inner front spindle, outer cone shape accuracy, surface roughness and their bearing journal positional accuracy. Spindle bearing journal of dimensional accuracy, shape accuracy and surface roughness of the main requirements for precision shaft parts, precision grinding method can guarantee. Should improve the accuracy of fine grinding prior to baseline. The guarantee front spindle, outer cone shape accuracy, surface roughness same precision grinding method should be used. In order to ensure the outer cone bearing journal relative positional accuracy of precision shaft parts, as well as the positional accuracy between the bearing journals, often using a combination of precision grinding shaft parts prices, the processing of these surfaces in a fixture, as Figure 6-4. The machine has two separate wheel frame craft precision shaft parts, grinding performed at two stations on the former station Ⅰ grinding, after the journal cone, the angle formed by the station Ⅱ wheel, grinding front spindle bearing surfaces and short cone.
