Drilling, Tapping & Threading

Drilling, Tapping & Threading

Drilling, tapping and threading create holes and threaded features required for assembly. These operations can be incorporated into the machining process according to the component drawing and technical specifications.

Precision Steel Machining & Dimensional Control

Precision steel machining requires careful control of critical dimensions, feature tolerances and surface quality. Yumei Hardware evaluates drawing requirements and applies appropriate machining and inspection methods to help achieve the specified results. For suitable features and machining conditions, tolerances can reach ±0.01 mm, with typical achievable surface roughness ranging from Ra 0.4 to 3.2 μm.
Dimensional Accuracy

Dimensional Accuracy

Critical dimensions are machined and checked against customer drawings. Tolerances down to ±0.01 mm may be achievable for suitable features, depending on part geometry, material and process conditions.
Geometric Feature Control

Geometric Feature Control

Holes, slots, mounting surfaces and multiple machined features are inspected according to specified dimensions and applicable positional requirements to support accurate assembly.
Thread & Fit Requirements

Thread & Fit Requirements

Threaded features, mating diameters and assembly interfaces are manufactured according to drawing specifications, helping ensure the required fit and function of custom steel components.
Surface Finish Control

Surface Finish Control

Surface quality is controlled according to component requirements. Typical achievable surface roughness ranges from Ra 0.4 to 3.2 μm, depending on the machining process and specified finish.

Steel Grades We Machine for Custom Components

组 1
Yumei Hardware provides custom steel CNC machining for components made from a range of carbon steels, alloy steels and tool steels. Commonly specified grades include 1018, 1045, 4140, 4340, 12L14, 1215, A2, D2 and O1, subject to project requirements and material availability. We review the specified material grade, applicable standard and supply condition according to your drawings and technical requirements.

Choosing the Right Steel Grade for Your Project

The right steel grade depends on more than the material name alone. Component geometry, required strength, hardness, operating conditions and dimensional tolerances can all influence material selection and machining feasibility. If your drawings specify a particular grade, Yumei can review the requirements before production. If the grade has not yet been finalized, share your application and technical requirements for further evaluation.

Surface Finishes & Secondary Operations for Steel Parts

The surface finish and secondary operations of steel CNC machined parts depend on the material grade, component design and intended application. Yumei Hardware reviews your drawing requirements to help determine suitable finishing and post-machining options for custom steel components. From edge deburring and thread finishing to application-specific surface treatments, each requirement is evaluated according to the part's functional and technical specifications.
Sandblasting
High-pressure abrasive is used to remove oxide scale, rust, and impurities from the steel surface, creating a uniformly rough surface. This improves the adhesion of subsequent coatings and optimizes the product's appearance consistency. Suitable for various structural components and sheet metal parts.
Powder Coating
Using electrostatic spraying, powder coating is evenly applied to the product surface. The coating is dense, uniform in color, and has excellent corrosion resistance and scratch resistance. Various colors can be customized according to customer needs. Widely used in exterior parts and outdoor components.
Electroplating
A layer of metal (such as zinc, chromium, or nickel) is plated onto the steel surface, effectively improving the product's rust and corrosion resistance while enhancing surface gloss. Suitable for precision parts and decorative products.
Blackening Treatment
Also known as oxidation treatment, a black oxide film is formed on the steel surface, providing rust and corrosion protection. The process is simple and cost-effective, suitable for mechanical parts and tools.
Polishing
Removes scratches and burrs from the product surface using mechanical or chemical methods, achieving a mirror or matte finish and enhancing the appearance. Suitable for stainless steel products, precision parts, and decorative components.
Electrophoretic
The electrophoretic coating process allows the coating to adhere evenly to the steel surface, forming a dense and uniform coating with strong adhesion and corrosion resistance. The coating is smooth and flat, making it suitable for precision parts, mechanical housings, and other products with high requirements for corrosion resistance and appearance.
