CNC Machining Services
3ERP provides a variety of precision CNC machining services including milling, turning, EDM (electrical discharge machining) and wire EDM, and surface grinding. With our precision 3-, 4- and 5-axis CNC machining centers, combined with other advanced capabilities and our experienced team, we can handle all technical aspects of creating your prototypes and parts, so your team can focus on bringing your product to market. Contact us today to get your manufacturing solution and details.
There are huge numbers of CNC machining service providers. Why should you choose us? Here are the top 3 reasons:
- Experience: Our engineers have built up rich, deep experience from many previous projects, so they can handle complex and precision parts in several industries without any problem.
- Advanced Equipment: 3ERP has extensive in-house equipment for both manufacturing and testing. Your parts will be manufactured and inspected with our advanced in-house equipment, including HAAS 3-, 4-, and 5-axis CNC milling, Hexagon CMM, and Olympus XRF analyzer.
- Fast Turnaround: On average we return quotes within 24 hours, parts ship within 7 days or less, and we have a 99% on-time delivery and quality rate.
CNC lathes allows us get high speed turning of both plastics and metals from bar or block material. The turning process allows the production of complex external and internal geometries, including generating all kinds of threads. For any round shaped components, for example, shafts, worms, spheres, CNC turning is a more efficient method compared with CNC milling. 3ERP’s turning capability can make prototypes all the way through mass production parts.
Compared with CNC turning, CNC milling services can be used to create complex 3D shapes, or to apply a machined surface or features to parts made both plastics and metals. The advantage of multi-axis milling machines makes CNC milling process versatile, as well as accurate and repeatable, for creating many different types of part features of complex geometries. Example include holes, curves, slots, angled shapes, and channels. Milling is also ideal for making tooling for pressure die casting and plastic injection molding.
CNC Machining Surface Finishes
|As Machined (standard)||~125 RA µin (3.2 RA µm). Minor tool marks will be visible on the part. Surface finish requirements can be increased to 63, 32, or 16 RA µin.|
|Bead Blast||Matte finish with light texture is achieved by blowing small glass beads against the part.|
|Anodizing Type II||Corrosion resistant finish. A variety of different colors can be applied when anodizing.|
|Anodizing Type III||Adds a wear resistant layer on top of the corrosion resistance of Type II.|
|Powder Coat||Strong, wear and corrosion resistant finish, that is more durable than the methods mentioned above. Powder coat finishing are available in large range of colors.|
Other surface finishes are available upon request, for more please see our surface finishing services.
CNC Machining Tolerances
With high precision milling & turning machines, we are able to catch super tight tolerance for prototype machining & production. Parts will be made accordingly to our customers’ specification. If 2D drawings are not available, you can also indicate with ISO 2678. The table below is the ISO 2678 standard for your reference.
