Advantages of CNC machining

1.Step 1 Be safe

The operator of the CNC machine is securely separated from all sharp parts by a special protective structure. He could still see what was happening on the machine through the glass, but he didn't need to go anywhere near the mill or the spindle. The operator does not have to touch the coolant. Depending on the material, certain liquids can be harmful to human skin.

2. Save labor costs

Nowadays, conventional machine tools require constant attention. This means that each worker can only work on one machine. When the CNC era came, things changed dramatically. Most parts take at least half an hour to process each time they are installed. But CNC machines are made by cutting the parts themselves. You don't have to touch anything. The tool moves automatically, and the operator simply checks for errors in the program or Settings. That being said, CNC operators find they have a lot of free time. This time can be used for other machine tools. Thus, one operator, many machine tools. This means you can save manpower.

3. Minimum setting error

Traditional machine tools rely on the operator's proficiency with measuring tools, and good workers can ensure that parts are assembled with high precision. Many CNC systems use specialized coordinate measuring probes. It is usually mounted on the spindle as a tool and the fixed part is contacted with a probe to determine its position. Then, the zero point of the coordinate system is determined to minimize the setting error.

4. Excellent machine condition monitoring

The operator must determine machining faults and cutting tools, and his decisions may not be optimal. Modern CNC machining centers are packed with different sensors. You can monitor torque, temperature, tool life and other factors while machining the workpiece. With this information, you can refine the process in real time. For example, you see that the temperature is too high. Higher temperatures mean tool wear, poor metal properties, etc. You can reduce the feed rate or increase the coolant pressure to solve this problem. Despite what many say, machining is the most widespread method of manufacturing today. Every industry uses machining to some extent.

5. Stable accuracy

What's more stable than a proven computer program? The movement of the instrument is always the same, because its accuracy depends only on the accuracy of the stepper motor.

6. Fewer test runs

Traditional machining inevitably has some test parts. The worker has to get used to the technology, and while doing the first part and testing the new technology, he will definitely miss something. CNC systems have a way of avoiding test runs. They use a visualization system that allows the operator to actually see the inventory after all the tools have been passed.

7. Complex surface processing is easier

For traditional machining, it is almost impossible to manufacture complex surfaces with high precision. It requires a lot of physical labor. The CAM system can automatically form the tool path on any surface. You don't have to make any effort at all. This is one of the biggest advantages of modern CNC machining technology.

8. Higher cutting parameters

High speed machining is possible only due to the closed cutting area. At this speed, the chip is flying all over the place at high speed. There is a coolant spray behind the chips because when it comes to high-speed machining, the coolant is applied under high pressure. At speeds of 10,000 rpm or higher, manual operation is simply not possible. The cutting speed is high and it is important to keep the feed speed and chip width stable to prevent vibration. Manual implementation cannot be difficult.

9. Higher processing flexibility

The traditional method is milling for grooves or planes, lathes for cylinders and cones, and drilling machines for holes. CNC machining can combine all of the above into one machine tool. Since the trajectory of the tool can be programmed, you can replicate any movement on any machine. Therefore, we have milling centers that can manufacture cylindrical parts and lathes that can mill grooves. All of this can reduce the number of parts set up.
