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 CNC Machining?
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.
What are the Advantages of 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 rapid prototyping, CNC machining excels in durability, precision, and material versatility.
FAQs About GCH CNC Services
GCH PROCESS 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! GCH PROCESS 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.
GCH PROCESS CNC Services is versatile in terms of material compatibility. Commonly used CNC materials include metals like aluminum, steel, brass, and copper, as well as plastics such as ABS, Polycarbonate, and POM. However, specific materials availability might vary, so it’s always a good idea to check directly with the service provider.
The expense associated with our CNC machining service is variable and directly influenced by the distinct attributes of your project, including its design and tolerance specifications. The machining duration for the chosen material is another key determinant of the cost. To illustrate, should you require a part where the combined machining and material expense is $2, with an additional setup charge of $200, the total cost for a singular part would amount to $202. Contrastingly, should you commission the production of 200 identical parts, the cost per unit would be just $3! Learn more about the CNC machining costs.
GCH PROCESS 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, GCH PROCESS aims to provide a solution.
Lead times can vary based on the complexity of the design, the chosen material, and the current workload at GCH PROCESS. 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.
