CNC Machining is an automated process that is widely used in the manufacturing industry. This machining technique is controlled through programmed commands, which are encoded on computers. Some of the examples of these machines include grinders, routers, lathes, and mills with the help of computers. This post will discuss different techniques of CNC machining that will help you get the best results.
What Are the Best CNC Machining Techniques?
Here are some of the top CNC machining techniques that guarantee best throughput:
1. Optical Grinding: CNC machining is of great help in making specialty optics. Optics require thin surfaces and close tolerances. Thus, with the help of grinding equipment you can spin and grind a wheel against a surface. This helps eliminate nominal deviations. You can also use grinding paste for lubrication purpose. This paste also gives a polished finish to the surface.
2. Wire EDM: This technique employs a copper wire, which acts as a conductor for high-voltage electric charge. This technique is typically used on any electrically conductive material to cut punch and dies for stamping metals and many other applications where conventional cutting tools can’t be used. This technique can hold tolerances of .0002” and leave very small radiuses in sharp corners.
3. Surface Grinding: In a number of applications, it is very essential to have metal parts with flat surfaces. This can be achieved with the help of a grinder. In this technique, the abrasive wheel or grinder is placed above the sliding table and the work piece is mounted on the table. The work piece is moved laterally back and forth on the table.
4. Turning: In this technique, the work piece is firmly clamped to a rotating chuck or collet. A cutting tool is mounted on a moving slide. The work piece is rotated, and the cutting tool is held against it. You can adjust or move the slide up and down, or closer and away from the work piece.
5. Cylindrical Grinding: This technique is a combination of the previous two techniques – turning and surface grinding. In the cylindrical grinding technique, the work piece is firmly held in one place, and. a cylindrical grinder is rotated along its surface. These grinders can either be used throughout the length of the work piece or at partial depths.
6. Solid Sink EDM: In the solid sink EDM technique, an electrode is bathed in a dielectric and placed near the work piece. This electrode is shaped perfectly for cutting. As the electrode goes on discharging, the metal particles start leaving the surface of the work piece.
7. Milling: In the milling technique, the work piece is stationary, and a cutting tool is made to rotate around the work piece. A lubricating fluid is used to lubricate the cutting tool. Also, this lubricating fluid also helps cool the work piece.
These are the seven different techniques of CNC machining. Each technique has its own advantages, as well as disadvantages. You can go with the technique that best suits your application requirements. If you are unable to make up your mind, you can easily approach a CNC machining service provider like China Manufacturing Parts . The company provides a wide variety of CNC machining services across various industries.
