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 CNC equipment according to the specification of your 3D design. Our team of engineers and machinists program the equipment to optimize cutting time, surface finish and final tolerance to meet your specifications. We use CNC machining not only to manufacture parts and prototypes but also to make mold tools, which can be used for our plastic injection molding or pressure die casting services.

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 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.
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 make hard tooling (cores and cavities) from a variety of materials to suit your budget, order volume and schedule. We routinely make production-quality tools from P20, NAK80, S136 stainless and H13 semi-hardened steel for volumes up to 100,000 pieces. Specialty metals can also be ordered on request.

CNC Machining Quickfacts
Why choose CNC machining?
CNC machining is a fast, accurate and versatile solution for making production-quality parts in any quantity, without the need for investing in hard tooling or expensive set-ups.
What raw materials can I use with CNC machining?
Finished parts can be made from many types of easily available stock metals including mild and stainless steel, aluminum, brass, copper, magnesium and titanium. We can also machine rigid plastics. Check out our list of frequently used materials.
What tolerances can I achieve with CNC machining?
We routinely produce parts to .05 microns, which is suitable for the majority of commercial and industrial applications. Closer tolerances are only advised for critical applications – they will take longer to produce and will increase processing costs.
