When manufacturing precision components, different processing methods and processes must be selected based on the physical properties that customers need to achieve, such as tolerances and materials, in order to ensure the quality and manufacturing costs of the parts. In the production of precision parts, the following points are used as judgments to determine the processing method:
1. Size of precision parts manufacturing parts
We specialize in manufacturing precision parts with high finish and tolerance requirements. Currently, our inner diameter is 15 μ M [0.0006 "] with a tip diameter of 35 μ M [0.0013 "], therefore the wall thickness is 10 μ M [0.0004 "], not all manufacturers have the ability to manufacture this high-precision part, some of which require five axis CNC machining.
2. Manufacturing and processing quantity of precision components
If the precision parts processing process shows complexity, a quantity as low as 2000 pieces may be economical. If it is mass production, production tools are needed to assist, and the upper limit of annual production is almost unlimited.
3. Manufacturing and processing tolerances for precision components
The tolerance performance can depend on the geometric structure of the component, but the rule of thumb is that the tolerance of the target dimension is ± 0.3% to ± 0.5% of the nominal tolerance. However, for secondary grinding and polishing, a tolerance of<5um [. 0002 "] is usually maintained. Please consult our technical personnel to analyze your precision parts.
4. Precision component manufacturing Part shape
Using traditional precision component manufacturing techniques to produce simple shapes may be more economical. Generally speaking, the higher the complexity, the greater the advantages of CNC machining of precision parts compared to other methods. A flat sintered surface helps to reduce manufacturing costs and program development time.
Before deciding on the processing method for precision parts, professional personnel can analyze it to avoid some technical problems and provide guarantee for product production!
