Why do engineers all over the world like to use cnc processing technology

Why is CNC machining so popular all over the world? How is it different from 3D printing. The processing of precision parts used in many industries is created by CNC processing and manufacturing technology. CNC machining is loved by engineers all over the world because it is one of the most precise manufacturing techniques available today.

1. CNC precision parts processing or computer numerical control machining is a digital manufacturing technology that provides high-precision parts directly from CAD. CNC machines can have varying numbers of axis rotation props, usually three or five axes. The basic CNC working procedure can be divided into three steps, first is the CAD model designed by the engineer, then the machinist converts the CAD file into the CNC program of the replacement code using the giant code engineer, machinist, design, CNC, machine tool and all the machining operate. Including environmental protection, cutting operations to make parts, and cooling of parts and tools.

2. During the manufacturing process, CNC processing tools, such as milling machines, lathes, grinding machines, etc., are all automatically controlled by computers, so no manual supervision is required. In the manufacturing process, due to the high degree of automation, precision parts processing manufacturers are very price-competitive for one-off custom parts and mass production.

3. CNC precision parts processing is a tailoring manufacturing technology, which is fundamentally different from technologies such as 3D printing and design molding, because parts are manufactured from solid materials by cutting materials, and this material will work for the blank The piece that the tool cuts on is the material. Cutting to complete, so why CNC machining 3D printing and injection molding so different? 3D printing is an additive technology, while injection molding is a molding manufacturing technique, which means that materials are added together to make parts during the manufacturing process. Contrary to the cutting material of CNC machining, almost any kind of hard material can be CNC processed after receiving the materials used for CNC machining, and the common materials are brass ABS and CNC machining.

4. CNC precision parts processing It can create customized parts with very strict tolerances, so it becomes one of the accurate manufacturing techniques. The long-term tolerance for machining metal or plastic is about plus or minus 0.125 mm, and tight tolerance features can be produced as low as 0.05 mm, which is about 1/4 the width of a human hair.
