At Star, we use advanced equipment to offer you a variety of CNC machining services including milling, turning, EDM and wire EDM, surface grinding and much more. Using our imported 3, 4 and 5-axis CNC machining centers, our skilled machinists can make parts using a wide range of plastics and metals.
Our CNC machining abilities also complement our 3D metal printing service making us a great one-stop-shop for your advanced designs. Contact our team for a free quote and to discuss which process is the right one for your next project.
What is CNC machining?
Computer-numeric controlled (CNC) machining is a subtractive manufacturing process, where raw material is removed with a variety of precision cutting tools. Advanced software is used to control the equipment according to the instructions of your CAD drawing file. Our team of machinists program the equipment to optimize cutting time, surface finish, and final tolerance to meet your design specifications.
Advantages of CNC machining
- Quick removal of large amounts of material
- Highly accurate and repeatable
- Suitable for many different kinds of substrates
- Scalable volumes from one to one-hundred thousand
- Low investment in tooling or preparation costs
- Fast turnaround
Our CNC lathes enable high speed and high quality turning of both plastics and metals. The turning process allows for complex external geometries and internal bores to be generated. Our turning capacity is available for one-offs through to batch production of your components.
Milling is used to apply a machined surface finish on plastic or metal or for creating complex 3D shapes. We use domestic and imported 3,4, and 5-axis CNC machining centers with quick-change tooling, programmed using advanced Delcam software.
EDM/Wire EDM and Surface Grinding
EDM (electrical discharge machining) is a method for cutting holes, pockets, and other shapes into hardened steel, as well as imparting a surface texture to the internal cavities of mold tools. A sacrificial electrode in an electrolyte bath discharges a high-powered electric spark to erode very hard materials that would be difficult or impossible to do with any other method. Square pocket holes are often created with this method.
With wire EDM, a copper wire is continuously fed between two spools. When electrically charged, it’s able to cut through hardened tool steels quickly and accurately.
At Star we also offer surface grinding services. Using this method, the workpiece is held stationary on a horizontal plate. The surface grinding wheel is computer controlled to abrade the workpiece to a precise depth.
Our general tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics DIN-2768-1-medium. Tolerances are greatly affected by part geometry and type of material. Our project managers will consult with you on every part of your project and will seek to provide the highest degree of precision possible.
We work with a wide range of materials including magnesium, steel, aluminum, brass, titanium, and many kinds of plastics to make parts for prototypes and low volume production. In addition to our stock list, we can provide you with any specialty raw material you require upon request.
Get your project started
With a range of finishing services to choose from and guaranteed quality thanks to our inspection services you can trust you will receive great parts every time. Once you send us your 3D CAD file for a free quote, one of our customer service engineers will check your design for manufacturability to ensure that the part can be made to your expectations and budget requirements.
