What’s the difference between CNC machining and 3D printing? The most straightforward answer is: 3D printing is a material additive technology, and CNC machining is a material subtractive technology. Differences in materials The materials of 3D printing mainly include liquid resin (SLA) , nylon powder (SLS) , metal powder (SLM) , gypsum powder (full-color printing) , sandstone powder (full-color printing) , wire (DFM) , sheet material (LOM) and so on. The materials of CNC machining are plates of ” stainless steel, plastic, brass, aluminum etc.” , through measuring the length, width, height of parts and wear, and then to cut the plate of the corresponding size for machining processing. 3D Printing material CNC Machining Material There are more choices of CNC machining materials than 3D printing, all metal and plastic plates can be CNC machined, and the density of molded parts is better than 3D printing. Differences of Part machining principles As we mentioned earlier, 3D printing is an additive manufacturing process. Its principle is that the model is cut into N layers/N multi-points, and then stack them layer by layer/point-by-point in order, just like building blocks.Therefore, 3D printing can effectively produce parts with complex structures, such as hollowed-out parts, while CNC is difficult to produce hollowed-out parts.CNC machining is a subtractive manufacturing process, through various high-speed tools, cutting out the required parts according to the programmed tool path. Therefore, CNC machining can only process rounded corners with a certain radian, but cannot directly process inner right angles, it must be achieved by EDM.
What is CNC MACHINING In summary, CNC Machining is usually refers to computer digital control precision macheries including of CNC machining grinding, routing, drilling, lathe, milling, turning to custom made any different types of parts with different materials including of metal aluminum, stainless steel, brass and plastic etc. CNC machining Service is a manufacturing technique for removing material. It uses sharp cutting tools, available in a variety of shapes and sizes, which are precisely controlled by a computer. CNC stands for Computer Numerical Control.

How Do CNC Machines Work? 1. CNC machining starts with a computer, on which designers prepare a part using CAD (Computer-aided Design) software. This digital part is then converted into a format that can be recognized by a CNC machine. 2. Instructions are sent to the CNC machine in the form of “G-Code” after which the machine can start cutting. 3. Most CNC machines have a “worktable” and work holding device to
Nowadays, many manufacturer factories still operate machine tools manually. With economic development, factories are becoming more and more industrialized. Many factories have already used computer digital control machine tools for operations. CNC machine tools can automatically control any Products and parts are processed directly What’s the advantages of CNC Machining? A CNC machining center is a CNC machine tool with a tool magazine and automatic tool change, which can perform multiple machining operations on the workpiece within a certain range. Compared with traditional manual operation, the advantages of CNC machining center are: 01: High processing accuracy and high processing quality When YOU looking for precision machining services, you can’t afford to compromise on the quality if you want to manufacture parts that meet your quality requirements. And at 3Q Machining, you will find a wide range of precision CNC machining services, an experienced team of experts, and extensive experience of how to best approach different projects using 3-, 4-, and 5-axis CNC machines. We offer milling, turning, EDM, wire EDM, and surface grinding services and can handle all the technical aspects of creating your prototypes and parts, allowing you to focus on bringing your product to the market. 02: Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed For complex and time-sensitive machined parts, 5-axis CNC machines offer
