What is CNC Machining?

CNC machining refers to a method where a control system issues instructions to make the cutting tool perform various movements that meet technical requirements and processing process requirements, represented in the form of numbers and letters to express the shape and size of the workpiece. This process is commonly carried out on CNC machine tools.

Common CNC machining methods include 3, 4, and 5-axis CNC milling, CNC turning, electrical discharge machining (EDM), CNC grinding, and more. Skilled machinists program the toolpaths based on the final geometry of the machined part to operate CNC machine tools. CNC machining can be used to produce highly precise components from a

Common Materials in CNC Machining

CNC machines can work with a variety of materials. We have listed some common materials suitable for CNC machining, but there are many more materials that we may not have listed. Please feel free to contact us for rare or specialized materials.



Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.

Primary Application Industries: Medical, automotive, aerospace, robotics, automation, and machinery.

Subtypes:Copper 101,Copper C110,Copper C932,Copper 260,Copper 360

Common Surface Treatments (Post-Processing)

During the CNC machining process, visible tool marks may be left on the surface as material is removed to create the desired shape. Typically, some post-processing is required to address this issue. There are various types of surface treatments available, each serving different purposes. At Shared-Factory, we offer a range of common surface treatments aimed at enhancing both functionality and aesthetics.

Shared-Factory is proficient in facilitating the production and prototyping of large machined parts, be it metal or plastic. We boast a substantial CNC machining build envelope measuring 20000 mm x 15000 mm x 6000 mm. This ensures we can accommodate even sizable parts, including those tailored for furniture or architectural applications.

Absolutely! The exact tolerance we offer is contingent upon your specific requirements. For CNC machining, our metal components adhere to the ISO 2768-m standards, while our plastic parts align with ISO 2768-c standards. Our highest precision level can reach an accuracy of 0.001 millimeters. It’s worth noting that the demand for higher precision will correspondingly increase the cost.

 For small quantities of standard parts, our fastest delivery is same-day shipping if ordered before the cut-off time. With expedited international shipping, the parts can arrive at your facility in about 3 days.For typical quantities, we can deliver most parts within 3 days of the order being placed.
