Shenzhen Dongguan Shaft Wheel Keyboard Lathe Product High Precision Custom 5 Axis CNC Prototype Machining Aluminium Parts

YMP mainly processes precision parts and machinery parts, manufactures parts of intelligent and automatic mechanical equipment, and is engaged in import and export trade, with a lot of production equipment and machines, such as milling machines, common lathes machines, automatic feeding CNC lathe machines, CNC machines, machining centers, drilling and tapping machines, buffing machines, grinders, etc.

Therefore, we have the capabilities to make products of various designs, sizes, and materials, and our products are at a low price but of extremely high quality. Our quality inspectors strictly adhere to the criteria of IQC, IPQC, and QA during inspection processes. Inspecting the raw materials, monitoring the manufacturing processes, and performing final inspections before shipment is our daily work.

Our company is located in China's special economic zones-Shenzhen City Baoan District, with a plant area of 7,500 square meters and more than 100 employees. And with customers mainly in Japan, Europe, and South East countries. Customers' need is always our priority.

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.

Surface treatments we can do:

Most CNC factories only focus on CNC machining but are not good at surface treatment. 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 the 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.
