CNC Machining Service
At Star Rapid, 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. Learn more about how we combine additive and subtractive manufacturing through our AddSub® service.

What Is CNC Machining?
CNC machining is a subtractive manufacturing process, where raw material is removed with a variety of precision cutting tools to make a part or product. Advanced software is used to control the equipment according to the specification of your 3D product design. Our team of engineers and machinists program the equipment to optimize cutting time, surface finish, and final tolerance to meet your design specifications.
Advantages Of CNC Machining
CNC machining is great to meet a range of your product development needs. Here are some of the benefits of precision machining:
- Quick removal of large amounts of metal 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
The Mina v2 is a powered robotic exoskeleton designed to provide assisted mobility to people with a physical disability. Using microcontrollers, sensors and electric motors with a sophisticated user interface, the Mina v2 competed in an international robotics Cybathlon in Switzerland in October.
CNC Turned Parts
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-off prototypes through to low-volume production of your product and parts.
CNC Milled Parts
CNC 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. When surface grinding the workpiece is held stationary on a horizontal plate. The surface grinding wheel is computer controlled to abrade the workpiece to a precise depth.
Tolerances For Precision Machining
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.
Materials Used For CNC Machining
We work with a wide range of plastic and metal materials including magnesium, steel, aluminum, brass and titanium to make tooling for plastic injection molding and pressure die casting or to make parts for rapid prototypes and low-volume production. In addition to our stock list, we can provide you with customized raw material as required.
