Guidelines for CNC machining of precision parts
Yixin Precision CNC Machining Factory believes that in the design of process standards, the correct selection of positioning data has a crucial impact on ensuring the processing requirements of parts and arranging the processing sequence reasonably.
The reference is divided into fine datum and rough datum: the rough reference is used as the positioning reference with the unmachined appearance on the blank. The fine reference takes the machined appearance as the positioning reference.
01 criteria for selecting a fine benchmark
(1) Benchmark coincidence criterion: the processed surface design data should be selected as accurately as possible to prevent data dislocation from forming positioning error.
(2) Consistent datum criterion: in order to ensure the relative orientation accuracy between the machined surfaces, as many surfaces on the workpiece as possible should be processed using the same set of fine benchmarks.
(3) Benchmark criterion of workpiece machined surfaces: the repeated machining method of two machined surfaces can be used as a mutual reference.
(4) Self-reference criterion: Some surface finishing processes requires small and uniform machining tolerance, and the machined surface itself is often used as the precision benchmark.
The four criteria mentioned above for selecting fine benchmarks are sometimes not satisfactory at the same time and must be decided according to the actual situation.
02 Criteria for selecting rough benchmarks
(1) The rough benchmark should be used in the first workpiece processing. Whether the rough benchmark is selected correctly is not only related to the processing of the first working procedure but also has a great influence on the whole working procedure of the workpiece.
(2) Principle of reasonable distribution of machining tolerance: the machining allowance of workpiece appearance should be uniform, and the important appearance should be taken as the rough benchmark.
(3) Easy-to-install clamp rule: In order to make the workpiece position stable and clamp firmly, Yixin Precision reminds you that the approximate reference point to be selected should be as smooth and clean as possible, free from lightning strikes, and the forging cut or other defects allow a satisfactory supporting area.

If the surface treatment of parts does not meet expectations, it will not only increase the cost but also affect the time to market products.
YMP has rich experience in surface treatment of metal parts, and we will choose a suitable surface treatment process according to different parts' materials and uses.
The common surface treatments of YMP include: electroplating, electrophoresis, painting, powder spraying, sandblasting, polishing, shot blasting, laser engraving, etching, CD pattern, silk screen printing, wire drawing, blackening, anodizing, hard oxidation, thick film oxidation, micro-arc oxidation and so on. No matter what personalized requirements your parts need, we can meet them.
There are various parts that can be processed by CNC, involving a wide range of industries.
YMP has many years of experience in making OEM parts, and there are 475 kinds of materials. Basically, we can process all the metal materials in the market, and we are equipped with spectrometers to ensure the authenticity of the materials. So you don't have to worry about material problems when you choose YMP. We have stocks of aluminum alloy, stainless steel, magnesium alloy, titanium alloy, zinc alloy, nickel alloy, copper, steel, and so on.
