Size precision shaft parts mainly refers to the accuracy of the diameter and length. Size diameter direction, if certain requirements with much more stringent requirements than the dimension of its longitudinal direction. Therefore precision shaft parts wholesale, for the size of the diameter is often prescribed strict tolerances. Luoyang Fuyuan Gear Machinery Co., Ltd. is the production of construction machinery, tractors and cars gear, shaft, disk parts-based, diversified into other products integrated manufacturing enterprises. Relatively large number available when mass production of precision shaft parts, often with smooth limit gauge test, the length of a large and high-precision workpiece; test-piece machined small batch production process precision shaft parts, dimensional accuracy for general use outside micrometer inspection Instrument testing. Roughness of the surface roughness can be used to test the model; the profiler with an optical microscope or higher when tested. Half roundness error is available within the same section of the workpiece micrometer diameter measured to determine the maximum difference can also be used by means of a V-shaped iron dial indicator to measure the precision shaft parts manufacturing, if conditions permit, available roundness testing. Cylindricity error is usually measured with a micrometer difference between the maximum and the minimum value method to determine the same axial section. Spindle mutual positional accuracy tests are usually the top hole in the top ends of the shaft taper plug hole or process for positioning reference in the above two bearing journals micrometer measurements were used.
