CNC Machined Parts

CNC machining is suitable for one-offs and up to hundreds of parts. We offer a wide variety of materials, including mild and stainless steel, aluminum, magnesium, zinc, brass and many plastics. Services include milling, turning, precision surface grinding, wire and EDM spark erosion and more. We also offer the production of precision-machined components. Our precision engineering department offers milling, turning, CNC engineering, surface grinding, wire erosion and EDM spark erosion. All of your projects will be discussed carefully and checked before production starts. During and after production the parts will be 100% inspected. We can provide original certificates for all materials used in the project as well.

Milled Parts

CNC milling allows us to quickly and accurately machine your parts from the stock material of your choice, in either plastic or metal. 2D and 3D shapes are easily created to a high standard of accuracy and surface finish. All CNC milling machine operations are programmed offline using Delcam Powermill software. Tool and job presetting help to insure fast turnaround and accuracy. The majority of CNC machines at Star Prototype are HAAS mills imported from the US. We also use HURCO machines from Taiwan as well as some local Chinese brands for projects of less demanding complexity.

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-offs through to batch production of your components.

CNC Machined Parts


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, and cannot be guaranteed. Our project managers will consult with you on every project and will seek to provide the highest degree of precision possible.


Please kindly refer to our online CNC material sheet.

Finishing Processes

Star Prototype offers a variety of finishing services for machined parts, including surface grinding, knurling, honing, painting, printing etc. We understand that the finish of your prototype is just as important as the features, so we train our operators on a variety of finishing techniques.
