We operate over 150 sets of 3, 4, and 5-axis CNC machines, and offer 100+ different types of materials and surface finishes, guaranteeing quick turnaround and quality of one-off prototypes and production parts.

CNC Milling

CNC milling removes materials from the workpiece to create custom-designed parts with flat surface using cutting tool or multi-point milling cutters.

WIth our 3-axis & 5-axis CNC milling services, you can get milled parts with tight tolerance up to 0.02mm (±0.0008 in.)

CNC Turning

CNC turning shears materials from the ouside of a rod at incredible speeds using a spinning tool. At AL Aluminum, we apply 50+ CNC lathes and CNC turning centers to create round or cylindrical turned parts with extreme precision that consistantly meet customers’ expectations.

CNC Machining Tolerances and Standards

With precision CNC machining services, AL Aluminum is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements on your drawing.

CNC Machining Overview

What’s CNC Machining?

CNC Machining, or Computer Numerical Control Machining, is a manufacturing technique where computer-controlled devices are used to remove layers from a material, creating detailed parts or components. Through a combination of tooling and precise machine movement, it produces parts to exact specifications.

What’s the CNC Machining Process?

The CNC machining process begins by designing a part in CAD software. This design is then converted into a set of machine commands using CAM software. The CNC machine reads these commands to precisely cut and shape the material, producing a finished part that matches the digital design.

Why Choose CNC Machining?

CNC Machining offers unparalleled precision and repeatability, making it a top choice for industries requiring intricate parts. Its ability to handle a variety of materials, from metals to plastics, combined with fast production times and consistent quality, makes it an essential method in modern manufacturing.

What’s the Difference Between 3D Printing and CNC Machining?

3D printing is an additive manufacturing method, building parts by depositing material layer by layer. In contrast, CNC machining is a subtractive method, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is often favored for complex geometries and AL Aluminum prototyping, CNC machining excels in durability, precision, and material versatility.

F.A.Q

Most frequent questions and answers

What are your maximum dimensions for CNC machining?

AL Aluminum is proficient in facilitating the production and prototyping of large machined parts, be it metal or plastic. We boast a substantial CNC machining build envelope measuring 2000 mm x 1500 mm x 300 mm. This ensures we can accommodate even sizable parts, including those tailored for furniture or architectural applications.

Absolutely! The exact tolerance we offer is contingent upon your specific requirements. For CNC machining, our metal components adhere to the ISO 2768-m standards, while our plastic parts align with ISO 2768-c standards. It’s worth noting that the demand for higher precision will correspondingly increase the cost.

Of course! AL Aluminum has the capability to produce upwards of 10,000 diverse prototypes on a monthly basis, spanning from simple to intricate designs. Our infrastructure is bolstered by 120 state-of-the-art CNC machines, and we pride ourselves on having a team of over 100 skilled technical experts.

AL Aluminum caters to both one-off prototype and large-scale production runs. Thus, there is typically no strict MOQ. Whether you need a single part or thousands, AL Aluminum aims to provide a solution.

Lead times can vary based on the complexity of the design, the chosen material, and the current workload at AL Aluminum. However, one of the advantages of CNC machining is its speed, especially for simpler parts. Once the setup is complete, machining times can be relatively quick. Parts delivered as fast as 1 day! But for an accurate estimate, it’s best to request for quotes directly.
