What are the Main Advantages and Disadvantages of CNC Machining?

CNC machining is a kind of lathe developed on the basis of ordinary lathes. Compared with ordinary lathes, it is widely used in mechanical parts due to its strong adaptability, high CNC machining accuracy, high CNC machining efficiency and reduced labor intensity. in production. While CNC machining has many advantages, they also have some disadvantages. This article will introduce the relevant content with the advantages and disadvantages of CNC machining.

CNC lathe can also be called CNC machining. It is a kind of machine tool that is used more now, accounting for about 1/4 of the entire machine tool. It will be used in any large or small production workshop. For beginners, it is easier to operate than ordinary lathes and can be used without a lot of operating skills.

CNC lathes are usually used to process workpieces of various shapes, such as brackets or forks, etc., and CNC machining programs are used to accurately cut the workpiece into the required shape. CNC turning parts are usually clamped and rotated by fixtures, through different widths and shaped cutting tools remove material to produce a symmetrical product. Let us briefly introduce the advantages and disadvantages of CNC machining.

Advantages of CNC machining

1. Strong adaptability: Strong adaptability is one of the more significant advantages of CNC lathes. When changing the machining workpiece, it is only necessary to rewrite the CNC machining program. After entering a new CNC machining program, new CNC parts can be machined without changing the hardware of the mechanical part and the control part. This provides a lot of convenience for mass production of CNC parts with complex shapes.

2. High CNC machining accuracy: Since the CNC lathe is driven by a motor to drive the ball screw, there is no gap in the transmission. During CNC machining, it is also controlled by the CNC machining program, and there will be no errors caused by manual operation, and it can also automatically compensate for tool wear and errors caused by other reasons. Therefore, the precision of the processed parts will be particularly high, and the quality will be particularly good.

3. High CNC machining efficiency: When CNC machining parts, it can use the automatic measurement function, and can automatically compensate for tool wear and errors caused by other reasons, reducing unnecessary waste in the CNC machining process. And when doing high-volume CNC machining, the operator can operate at least two CNC lathes. Therefore, its CNC machining efficiency is relatively high, and it also reduces the required CNC machining time. Its CNC machining efficiency is usually 4 times that of ordinary lathes.

4. Reduced labor intensity: Most CNC lathes now use hydraulic chucks. When clamping workpieces, the clamping force of the hydraulic chuck can be easily adjusted, and CNC lathes usually choose to use rotary tool holders. During CNC machining, the tool can be automatically changed, and the CNC machining of multiple technological processes can be continuously performed. In this way, the labor intensity of the operator will also be reduced.

Disadvantages of CNC machining

1. The price is relatively high: Because the internal structure of the CNC machining machine is relatively complex, the cost of producing the lathe is relatively high, and the price is relatively high. The price of an ordinary lathe is usually around tens of thousands of yuan, but the price of a CNC lathe is usually around several hundred thousand yuan, so its price is much higher than that of an ordinary lathe. For some small businesses, such prices are unacceptable.

2. The cost of single-piece CNC machining is relatively high: Now, the single-piece CNC machining cost of CNC lathes is higher than that of ordinary lathes, which is an indisputable fact. However, if it is improved, the cost of single-piece CNC machining can be similar to that of ordinary lathes.

3. High requirements for the working environment: It has high requirements for the working environment. It needs to be far away from the source of the earthquake, humid and corrosive gas environments, and it also needs to avoid sunlight and other thermal radiation. If there is a vibration source around the CNC lathe, it is necessary to build a shock-proof groove around it, otherwise it will directly affect its CNC machining accuracy.

By browsing the above articles, you can understand the advantages of CNC machining, as well as its disadvantages, such as relatively expensive price, relatively high cost of single-piece CNC machining, and high requirements for the working environment. At the same time, you can also learn that CNC machining is a kind of machine tool that is used more now, which can account for about 1/4 of the entire machine tool.
