Exploring CNC milling services in China

Whether you need basic prototypes or intricate, multi-feature components, XINQIDA’s advanced CNC milling—spanning 3-axis, 4-axis, and 5-axis technologies—ensures exceptional precision for every design. With both vertical and horizontal milling platforms in-house, we machine diverse geometries and varying part sizes efficiently, achieving consistent dimensional accuracy and rapid delivery on every project.

Advantages of four-axis CNC milling services

4-Axis CNC Milling extends 3-axis capabilities with precise rotational movement for complex geometries and angled features. It efficiently machines cylindrical, helical, and multi-sided metal or plastic parts in a single setup, reducing time and errors. Advanced programming ensures high precision, tight tolerances, and consistent surface finishes. Quick changeovers and flexible batch sizes make it ideal for prototyping and small-to-medium production, offering accurate, reliable, and cost-effective machining for intricate components.

Advantages of five-axis CNC milling services

5-Axis CNC milling allows precise machining along five directions, completing multi-sided and angled features in a single setup. Suitable for metal and plastic materials, it delivers high precision and efficiency while supporting small-batch or multi-variety production. Advanced control and stable performance ensure tight tolerances and superior surface finishes, making it an efficient, flexible, and cost-effective solution for complex components.

Advantages of three-axis CNC milling services

3-Axis CNC Milling provides stable, reliable, and cost-effective machining for metal and plastic parts. Its three-axis movement handles milling, drilling, and slotting efficiently. Simple programming and setup allow quick changeovers and flexible small-batch production. Easy to operate and maintain, it delivers consistent accuracy and surface quality. Suitable for prototyping and production, 3-axis CNC milling offers an efficient, precise, and economical solution for diverse manufacturing needs.

CNC Milling Surface Finishes

Different surface finishing is available for milling parts, such as painting, anodizing, and chroming. This will enhance function and aesthetic appearance greatly.

Anodizing

Creates a protective oxide layer on aluminum surfaces, enhancing corrosion resistance, wear resistance, and allowing for coloring.

Powder Coating

Provides a durable and decorative finish by applying a dry powder that is cured under heat, protecting against scratches and corrosion.

Electroplating / Plating

Deposits a thin layer of metal such as nickel, chrome, or zinc on the surface to improve corrosion resistance, wear resistance, and appearance.

Polishing / Buffing

Smooths rough surfaces, removes minor imperfections, and produces a bright, reflective, or mirror-like finish.

Bead Blasting / Sand Blasting

Uses abrasive media to clean the surface and create a uniform matte or textured finish for aesthetic or functional purposes.

Passivation

Mainly used for stainless steel to remove free iron from the surface, enhancing corrosion resistance and prolonging part lifespan.

Heat Treatment / Surface Hardening

Alters the material’s microstructure to increase surface hardness and wear resistance, commonly applied to steel parts.

Chemical Etching / Deburring

Removes burrs, sharp edges, or unwanted material after machining, improving precision, safety, and assembly fit.
