Customized Stainless Steel Bending Stamping Metal Sheet Fabrication

Customized Stainless Steel Bending Stamping Metal Sheet Fabrication

We operate almost every kind of CNC mill and turning center, and pride ourselves on being able to machine whatever you need, from simple, 'as-machined’ workholdings to complex, organic geometries with tight tolerances.

On request, we can also produce parts with EDM and grinders. The accuracy of wire cutting is comparable to that of a grinder (0.005 mm unit)

* In addition to straight cutting, it can also cut into arcs and process complex shapes, such as a combination of straight and arcs.

* As long as it is a conductive material, it can be machined from sheet to cemented carbide regardless of the thickness, size, and hardness of the material. There is no direct contact between the tool electrode and the workpiece, but there is a spark discharge gap.

This gap is generally between 0.05~0.3mm, and sometimes it may reach 0.5mm or even larger. The gap is filled with a working fluid, and the high-pressure Pulse discharge discharges corrosion on the workpiece. There are many features measured by the CMM, and almost all types of dimensional measurements can be measured by the CMM. Through the structural features, it is possible to detect flatness, roundness, concentricity, etc.

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 of products.

YMP has rich experience in surface treatment of metal parts, and we will choose suitable surface treatment process according to different parts materials and uses.

The common surface treatments of YMP include: electroplating, electrophoresis, painting, powder spraying, sand blasting, 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.
