Precision parts processing, — Technical requirements of shaft parts processing

by:Xavier      2020-07-07

you know precision machining axial parts is one of common parts, small make up also share with you before the shaft parts machining techniques and problems when, so today we take you to understand the technical requirements of a shaft parts processing:

today we in three ways:

the first: dimensional accuracy, shaft neck are the main surface of shaft parts, it affects axis rotation accuracy and working condition. The diameter of the shaft neck accuracy according to the requirements of the use is generally IT6 ~ 9, precision shaft neck of IT5. The second:

geometry precision of the geometry precision of shaft neck ( Roundness and cylindricity) , the general should be limited in the range of diameter tolerance points. For geometric accuracy requirement is high, can be in the detail drawing shall be stipulated separately on the allowed tolerance.

the third: the location of the processing, mainly refers to the assembling precision of transmission parts with journal relative to the assembly of bearing supporting shaft alignment, is used to cooperate with journal radial circular runout of supporting shaft neck to say; According to the regulations of the demands of high precision shaft is 0. 001-0. 005 mm, and general precision shaft is 0. 01 ~ 0. 03mm。 In addition to the cylinder alignment and axial positioning end face and the axis vertical degree requirements and so on.

4: surface roughness, according to the surface of working parts of the different parts, but have different surface roughness value, such as the surface roughness of the common machine tool spindle bearing journal for Ra0. 16 ~ 0. 63 um, cooperate with the surface roughness of the shaft neck for Ra0. 632. 5 um, along with the increase of the running speed of the machine and precision of shaft parts surface roughness value requirements will be smaller and smaller.

our company is specialized in manufacturing metal non-standard parts, ¢0. 5 - ¢20 mm stainless steel, titanium, aluminum etc metal precision parts manufacturing for many years precipitation technology.

our main products include: non-standard miniature components, stainless steel components, medical equipment accessories, lighting accessories, fasteners, connectors, axis of instrument fittings, bushings, fiber optic connectors, lc, sc tail handle handle accessories, precision machinery parts, fiber optic communications, screw nut, electronics accessories, copper, aluminum rivet and other civilian and military high standards of high quality high cleanliness of more than 200 varieties of products, for customers to choose from. In addition we can also according to the different requirements of customers, create customer satisfaction products.
