Do you want to understand tungsten carbide mold parts processing, after yize ma knows the problem, under the professional to research the data, what is really drill book, everyday pictures pavilion, and run every day workshop with a professional understand just out of the tungsten carbide mold parts processing of technical data, hope to don't quite understand tungsten carbide mold parts processing technical requirements you have to help , don't be too thank yize ma, for you to solve the problem of the relevant technology of the tungsten carbide mold parts processing. I was really very happy, but remember, later if need to use tungsten carbide mold parts , connector mold parts, plastic mold components, round piece of custom, the mould, such as tungsten carbide mold parts processing accessories wholesale products can find yize ma, the price will be low to make you proud .
Tungsten carbide mold parts processing technical requirements mainly in the following aspects:
Dimensional accuracy, tungsten carbide mold parts processing shaft parts surface is often two major categories.
One kind is cooperate with the inner ring of the bearing of the cylindrical shaft neck, namely the supporting shaft neck, used to determine the position of the shaft and supporting shaft, high dimension accuracy requirement, usually for IT 5 it7.
Another kind of journal to cooperate with all kinds of transmission parts, namely the coordinate axis neck, its precision is a bit low, often for IT6IT9.
Geometric accuracy mainly refers to the surface of the tungsten carbide mold parts processing shaft neck, conical surface, the surface of the cone hole, and other important roundness and cylindricity. Its error generally should be limited within the scope of the size tolerance, for precision shaft, need on the part drawing shall be separately stipulated the geometry accuracy. Position accuracy of including interior and exterior, important on the surface of the shaft alignment, round radial runout and end face important axis of verticality and parallelism between the end face, etc.
The surface roughness of tungsten carbide mold parts processing shaft processing surface roughness requirement, generally determine according to the possibility of processing and economy. Supporting shaft neck is often 0.21.6 m, drive a journal for 0.43.2 m.
Other heat treatment, chamfering, chamfering and exteriors and other requirements.
Above is yize ma to sort out the relevant technology of the tungsten carbide mold parts processing information, don't know or don't understand friend can see.
