CNC Turned Parts

Our CNC lathes enable high speed and 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 prototypes through to low-volume production.

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 CNC machining centers with quick-change tooling, programmed using advanced 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 wire is continuously fed between two spools. When electrically charged, it’s able to cut through hardened tool steels quickly and accurately.

At Jierui, 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.

CNC Machining Tolerances

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.

CNC Machining Materials

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.
