CNC Milling Services

CNC milling is a manufacturing process that uses computer numerical control (CNC) machines to remove material from a workpiece. It works by rotating cutting tools while the workpiece is held in place, allowing for precise shaping and machining.CNC Milling refers to the process of using rotating multi-blade cutting tools to cut the workpiece. It is an efficient machining method. During operation, the tool rotates (as the main motion) while the workpiece moves (as the feed motion). The workpiece can also be fixed, but in this case, the rotating tool must still move (to simultaneously perform both the main and feed motions).

CNC milling offers high precision, accuracy, and repeatability. It allows for complex geometries and can work with various materials. It also enables efficient production rates and can be used for both prototyping and production.

Industries such as aerospace, automotive, medical, electronics, and prototyping frequently utilize CNC milling services for their manufacturing needs.

Yes, CNC milling can be used to produce both simple and complex parts. It is highly versatile and can handle a wide range of geometries and designs.

For normal milling machines, they cannot change the tools, so they can only perform simple milling operations. However, CNC machining centers have multi-axis control capabilities such as 3-axis, 4-axis, and 5-axis. They are equipped with their own tool libraries and can perform uninterrupted tool changes. Additionally, the workpiece can rotate during the machining process. Therefore, for the machining of complex workpieces, 3-axis, 4-axis, and 5-axis CNC machining centers are usually chosen, while simple workpieces can be completed using regular milling machines.

Having accumulated years of experience in 5-axis machining, Masion is proficient in handling complex components, particularly impellers, wheel hubs, and automotive cylinder housings. With their extensive machining expertise, they are well-equipped to assist clients in resolving challenges related to intricate parts.

CNC milling can be used with various materials, including metals (such as aluminum, steel, and titanium), plastics, wood, and composites.

The primary difference between 3-axis, 4-axis, and 5-axis CNC milling lies in the number of axes of motion and the machining capabilities they offer.

Three-axis CNC milling: This setup involves three linear axes of motion, usually referred to as X, Y, and Z. The X-axis represents left and right movement, the Y-axis represents forward and backward movement, and the Z-axis represents up and down movement. Three-axis machines are suitable for machining parts with simple geometries, such as flat or slightly curved surfaces. However, they may face limitations when machining complex features or multiple faces that require angled cuts.

Four-axis CNC milling: In addition to the three linear axes, four-axis machines incorporate an additional rotational axis, often referred to as the A-axis. This rotational axis allows the workpiece to rotate 360 degrees in the horizontal plane. Additionally, some four-axis machines may have a second rotational axis called the B-axis, enabling the workpiece to rotate in the vertical plane. This setup enables more complex machining operations and offers increased flexibility. Four-axis machines are commonly used for machining parts that require drilling holes or milling features on multiple sides or curved surfaces.

Five-axis CNC milling: Five-axis machines take the capabilities of four-axis machines further by adding an additional rotational axis, usually called the B-axis, which provides a 360-degree rotation in the vertical plane. With five axes of motion (X, Y, Z, A, B), these machines offer the highest level of machining versatility. They can perform complex operations and reach difficult-to-access areas of a workpiece. Five-axis CNC milling is ideal for manufacturing intricate and precise parts that require multi-sided machining, such as aerospace components, medical implants, and complex molds.

In summary, as the number of axes increases from three to five, CNC milling machines become capable of handling more complex geometries, allowing for a wider range of machining operations and increased precision. The choice of the appropriate machine depends on the specific requirements of the part being produced and the desired level of complexity in the machining process.

Masion CNC milling machines(link to machine）, including their 3-axis, 4-axis, and 5-axis machines, are recognized for their high accuracy in precision machining. These machines are capable of achieving tight tolerances of approximately ±0.01mm. This level of accuracy allows for the production of precise and intricate parts with consistent dimensions.

The time required to complete CNC milling parts can vary depending on factors such as the complexity of the part, the quantity being produced, the availability of the CNC machines, and the workload of the CNC milling service provider. However, as an example, Masion, with their 30 sets of CNC machining centers, typically takes the following timeframes:

Sample Production: Masion can complete the production of sample parts within approximately 7 days. This allows for testing and verification of the design before moving on to larger-scale production.

Small Order Production: For small orders, Masion usually requires around 10-15 days to complete the milling process and deliver the finished parts.

Mass Production: If you have a larger production quantity, Masion typically allocates around 20-25 days to complete the milling process and produce the desired quantity of parts.

It’s important to note that these timeframes are provided as examples and can vary depending on the specific project requirements and the workload of the CNC milling service provider. It’s recommended to consult directly with the service provider to get a more accurate estimate for your specific project.

Yes, CNC milling services can provide custom designs. Masion, for example, has three designers in our R&D department(链接到R&D） who can work with clients to create custom 2D or 3D CAD models. These designers can collaborate with clients to modify drawings and ensure that the desired part is accurately designed. Once the design is finalized, Masion can program our CNC machines to produce the custom part according to the specifications. CNC milling services often offer design and programming capabilities to meet the specific requirements and customization needs of their clients.

The maximum size of a workpiece that can be milled with CNC machines can vary depending on the specific CNC machine and its capabilities. However, as an example, a CNC machining center like Masion that you mentioned can typically work with a workpiece size of approximately 800mm in length, 800mm in width, and 500mm in height. Additionally, it can accommodate workpieces with a diameter of up to 500mm.

The cost considerations for CNC milling services include various factors that can influence the overall pricing. These factors typically include:

The complexity of the Part: More complex parts with intricate designs or tight tolerances may require additional machine setup time, specialized tooling, or multiple machining operations, which can increase the cost.

Material Selection: Different materials have varying costs, and certain materials may require special cutting tools or machining techniques, impacting the overall price.

Machine Setup Time: The time required to set up the CNC machine for a specific job can affect the cost. Complex setups or frequent changeovers may increase the setup time and, subsequently, the cost.

Quantity: The number of parts needed can impact the pricing. Larger production runs often benefit from economies of scale, leading to lower per-unit costs.

Additional Services: Any additional services required, such as surface finishing, heat treatment, or assembly, may add to the overall cost.

When providing CNC milling services, Masion considers these factors and provides individual workpiece quotations based on the customer’s drawings and specific requirements. An accurate price can be determined by assessing the complexity, material, quantity, and setup time. It is also worth noting that the general market quotation for CNC milling services often falls within the range of 9-11 USD per hour of machining, but this can vary based on the location and specific service provider.
