CNC milling is a computer-controlled machining process that uses a rotating cutting tool to remove material from a stationary workpiece, allowing for the creation of complex shapes, holes, and surface features. This process enables manufacturers to produce custom CNC parts with tight tolerances, widely used in industries such as aerospace, consumer electronics, and industrial machinery.
3ERP is an ISO 9001:2015 certified CNC machining service provider, offering high-precision custom machining services for prototypes, low-volume production, and full-scale manufacturing.
With our in-house CNC machine shop, we offer fast lead times and competitive pricing. We help businesses worldwide manufacture precision CNC-milled parts for a wide range of industries.
Our advanced online CNC machining services offer the flexibility to meet your design needs and development timelines. We produce prototypes, test parts, and low-volume production runs with the speed and accuracy needed for modern product development.
We offer a wide range of CNC machining materials, including metal alloys, plastics, wood, and composites, carefully selected for strength, durability, and cost. Our engineers provide DFM guidance to optimize your plastic and metal parts design for manufacturing. Contact us or upload a CAD file for material options, instant quotes, and custom production solutions.
CNC milling supports a wide range of additional metals, plastics, and composites.

At 3ERP, we provide a full range of CNC milling surface finishes that enhance both functionality and appearance, improving durability, resistance to corrosion, and aesthetics as part of our comprehensive CNC machining process.
Good CNC milling design improves machinability, lowers costs, and ensures quality. When milling, avoid deep pockets, thin walls, and sharp inside corners; use generous radii to reduce stress and tool wear. Chamfers enhance appearance and safety. Limit complex multi-axis curves to simplify fixturing. Explore our full CNC design guide for more tips.
Thanks to 3ERP's 5-axis machining capabilities, we’re able to push the limits on our uprights and wheel package designs for maximum performance. Their bespoke and rapid manufacturing services allowed us to complete our project on time and ahead of schedule.

CNC(Computer Numerical Control) milling machines process parts by securing the material or workpiece to the machine bed. A high-speed spindle holds the cutting tool to remove material. The spindle and bed move horizontally and vertically to adjust the workpiece's position, enabling precise cuts of different shapes and depths. Machines with multi-axes allow the tool to reach various surfaces and complex areas, reducing programme setups.
3ERP operates two CNC machining workshops with over 60 advanced CNC machines, enabling rapid turnaround from prototype to production. Through our custom CNC machining services, we deliver precision CNC machined parts in as fast as one day, with most orders completed within 5 days. Backed by over 15 years of experience, our skilled engineers and machinists manage every machining process with expert design support, clear communication, and precision manufacturing. Rigorous quality assurance processes back every project to ensure consistent accuracy for both prototypes and production parts. We’re proud to serve as your reliable manufacturing partner, committed to your success.
We provide free DFM analysis for all CNC machining services to help optimize your design for cost-effective and high-quality manufacturing. Once we receive your RFQ, our sales representative will contact you within 48 hours. Our engineers will review your CAD file and provide feedback, along with optimization suggestions for CNC machining if necessary. Our goal is to improve machined part quality and identify opportunities to reduce machining costs, ultimately helping to lower your unit price.
