2 Turning Services

CNC turning is another highly sought-after service where the workpiece rotates while a cutting tool is fed into it, shaping the material to the desired dimensions. This service is particularly well-suited for producing cylindrical parts like shafts, rods, and spacers with a high degree of precision. The repeatability and speed of CNC turning make it a cost-effective option for both short and long production runs. Precision metal parts that require tight tolerances and smooth surface finishes benefit greatly from the capabilities of CNC turning.

4 EDM Services

Electrical Discharge Machining (EDM) is a specialized CNC service that molds metal parts by using electrical sparks to remove material. This process can cut extremely hard metals with intricate contours that would be difficult or impossible to achieve with traditional machining methods. EDM is divided into two main types: wire EDM and sinker EDM, each suited for different applications. Wire EDM is excellent for creating precise cuts and intricate details, while sinker EDM is used for complex geometries with fine finishes.

6 Finishing Services

The final touches to precision metal parts are often as critical as the machining itself. CNC finishing services include processes like anodizing, powder coating, and bead blasting, which enhance the surface properties of the metal parts. These finishes can improve corrosion resistance, surface hardness, and aesthetic appeal while also providing additional durability. Selecting the appropriate finishing technique is crucial to ensure that the final product meets both functional and visual quality standards.
