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.
Using imported multi-axis milling machines from the United States and Japan, as well as the top brand from China, we are easily able to guarantee CNC milling parts that are within the tolerance of +/-0.05mm, while also keeping critical dimensions under +/- 0.005mm. Another important thing, of course, is that our expert team of engineers know how to make precise parts.
Our 5-axis CNC milling machines come with an on-site inspection system that allows us to inspect the actual dimensions of a part during the milling process. The computer is able to automatically adjust the program and parameters to ensure that parts are done correctly.
Unlike CNC milling, the CNC turning process uses a single-point cutting tool to create precise cylindrical cuts into a rotating material. This automated technique provides great accuracy and a high-degree of repeatability, and is especially ideal for manufacturing circular or tubular shapes. The CNC turning lathe secures and rotates the material as its machined at high speeds.
Combined with the expertise of 3ERP, we are able to achieve incredible accuracy and exact components with our professional-grade CNC turning machines. While CNC milling is ideal for short-run volumes of prototypes and parts that are below 2.5” OD, CNC turning machines are better-suited for short-run volumes of larger parts above that threshold.
Common applications for CNC turning include functional prototypes, spacers, manifolds, fittings, shafts, and bushings.
Alongside CNC our services, 3ERP also provides industrial-grade wire electrical discharge machining (EDM) to our global customer base. Wire EDM is used to cut many types of electrically conductive materials.
The process involves an electrically-charged EDM wire that is positioned between two mechanical guides, which forms an electrode, while the material that is being cut generates the second electrode. This creates an electrical discharge between the wire and work piece, effectively cutting away from the material.
Since the wire doesn’t actually make physical contact with the material, EDM machining can be used to produce parts and prototypes that are extremely small and delicate. This method is able to cut through metal materials that are difficult to handle with other methods, including steel, bronze, copper, titanium, and others. It’s commonly used to produce circuit boards and essential equipment for the automotive, aerospace, and consumer electronics industries.
3ERP’s prototyping facility is also equipped with high-precision grinding machines. This process is used to manufacture metal parts and prototypes with very tight tolerances. Grinding uses a spinning wheel composed of bonded abrasive particles to remove material from a workpiece until it meets the desired shape and specification.
Like Wire EDM, precision grinding is best suited for manufacturing tiny metal parts and larger parts that require tighter tolerances, including components for medical devices, aerospace parts, scientific instruments, and more.
3ERP’s expert staff will help you decide on the optimal grinding method and tool for your part, taking all specifications and requirements into account.
Workshop environment - Temperature stability is very important, so 3ERP has installed an industrial-grade air conditioning unit in the workshop to keep the temperature around 20℃ at all times
We also use precise tool holders and tools to ensure optimal precision and accuracy. We recommend utilizing heat shrink tool holders from MST or HAIMER.
