CNC Milling

CNC milling is a subtractive manufacturing process that utilizes 3-axis, 4-axis, or 5-axis milling machines to remove material from solid blocks of plastic or metal in order to create final parts with different geometries.

The number of axes refers to the directions in which the milling machine can move the cutting tool. A 3-axis CNC milling machine can move the cutting tool in the X, Y, and Z directions, while a 4-axis machine can also rotate the workpiece. A 5-axis CNC milling machine adds the capability to tilt and rotate the cutting tool, allowing for even more complex machining operations.

CNC milling machines use various cutting tools, such as end mills, drills, and reamers, to precisely remove material from the workpiece. The cutting tools rotate at high speeds and are guided by the CNC machine's computer-controlled movements based on the programmed instructions.

One of the significant advantages of CNC milling is the ability to achieve tight tolerances. Tolerance refers to the allowable deviation from the desired dimensions or specifications of a part. Tolerances are typically expressed in units of length, such as millimeters (mm) or micrometers (µm). A tolerance of 0.01mm (or 10 micrometers) indicates that the finished milled parts will have a high level of accuracy and precision, with deviations within that specified range.

By utilizing 3-axis and 5-axis CNC milling services, you will have access to advanced milling capabilities that can accommodate complex part geometries and achieve tight tolerances. This opens up possibilities for creating intricate and precise custom parts for various applications.

It's important to communicate your specific tolerance requirements and part specifications to the CNC milling service provider to ensure they can meet your needs.

CNC milling involves the cutting of solid plastic or metal materials to produce precision parts using various milling processes. Unlike CNC lathes that rotate the workpiece, CNC mills remove material by rotating and moving a cutting tool, typically a milling cutter, while positioning the workpiece appropriately to achieve the desired shape.

The advantage of CNC milling lies in its ability to create complex geometries and features with accuracy and repeatability. By utilizing multi-axis milling machines, such as 3-axis, 4-axis, and 5-axis machines, manufacturers can achieve greater flexibility in creating intricate shapes, channels, holes, curves, and corners. These machines allow for precise control over the cutting tool's movement in multiple directions, resulting in highly detailed and complex parts.

Additionally, CNC milling can be utilized in the production of tooling for other manufacturing processes, such as die casting and injection molding. By milling molds or dies, manufacturers can create high-quality tooling that enables the production of consistent and accurate parts in large quantities.

Overall, CNC milling provides a versatile and efficient method for manufacturing precision parts with complex geometries, making it an essential process in various industries.

There are the number of axes on a CNC milling machine determines its capabilities and the complexity of parts it can produce. Higher-axis machines offer increased flexibility in creating intricate shapes and cutting angles, allowing for the production of complex parts.

Our company offers a comprehensive range of professional finishing services to enhance the appearance, performance, and durability of parts. Here are the major finishing services we provide:

Anodizing: Anodizing is an electrochemical process primarily used for aluminum parts. It creates a protective oxide layer on the surface, improving corrosion resistance and providing a decorative finish. Anodizing can also be combined with dyeing to add color options.

Painting: Our painting services allow for the application of various paint types to achieve desired colors, textures, or protective layers. Spray painting and powder coating are commonly used methods to enhance the appearance and surface qualities of parts.

Pad and Silk Screen Printing: These techniques are used to apply custom designs, logos, or labels to parts, aiding in branding, product identification, or adding instructional information to improve visual appeal.

Sanding and Polishing: We use abrasive materials in our sanding and polishing services to remove surface roughness and imperfections, achieving a smoother, more refined finish that enhances the parts' appearance and texture.

Vapor Polishing: This method is specific to plastic parts, using solvents or chemicals to smooth the surface, remove imperfections, and produce a glossy, clear finish, thus improving the quality and aesthetic of plastic components.

Powder Coating: In this dry finishing process, a fine powder is electrostatically applied to a part's surface, then heated to allow the powder to melt and form a tough, protective layer, offering excellent resistance to corrosion, chemicals, and UV exposure.

Blasting: This technique uses high-velocity particles or beads to clean the parts' surface, effectively eliminating imperfections, burrs, and sharp edges for a uniform, matte finish, enhancing surface quality and preparing for further treatments or applications.

Leveraging our comprehensive finishing services ensures that your parts meet functional specifications and are enhanced in appearance, performance, and durability. Our experienced team will collaborate with you to select the most appropriate finishing methods for your needs.
