The difference between CNC lathes and ordinary lathes.

1. Fully enclosed or semi-enclosed protective device is used on CNC lathes to prevent chips or cutting fluid from flying out, which can bring accidental injury to the operator. 2. Adopt automatic chip removal device Most of the CNC lathes adopt the layout of inclined bed structure, which is convenient for chip removal and convenient for the use of automatic chip removal machine. 3. The spindle speed is high, and the workpiece clamping is safe and reliable.

Most of the CNC lathes use hydraulic chucks, which is convenient and reliable to adjust the clamping force, and also reduces the labor intensity of the operators. 4. Automatic tool change CNC lathes all use automatic rotary tool holders, which can automatically change tools during the processing process and continuously complete the processing of multiple processes. 5. The main and feed transmission are separated The main drive and feed drive of the CNC lathe adopt their own independent servo motors, which makes the transmission chain simple and reliable, and at the same time, each motor can move separately and can also realize multi-axis linkage.

6. The ordinary lathe is manually operated, flexible, and the force distance of the same large equipment is large. Machining curved surfaces, lathes are troublesome for processing products with tapers and arcs, etc. It only has a spindle motor.

Shake the carriage with your hand on the knife. There are no detection devices and display devices, except for digital displays. It is convenient to process a single product.

2.CNC lathe he is a CNC system to control everything, passing, speed, feed, can profile machining. The force distance of the same large equipment should be smaller, and each part should be more precise, which can facilitate the processing of their respective surfaces.

It has a detection device and a display device. It is suitable for the production of large quantities of parts.

Compared with ordinary machine tools, CNC machine tools have the following characteristics: (1) Advantages 1High machining accuracy and high processing quality; CNC machine tools use CNC programs to control machine tools to achieve automatic processing.

What is the difference between CNC machine tools and ordinary machine tools?

Answer: their difference is mainly the difference of what kind of control, ordinary machine tools are controlled by the human brain, when the brain needs to carry out a variety of cutting, the brain will be related to the cutting matters in all the activities of the human hand plus the machine function organically combined to complete the machining action.

The control of CNC machine tool is controlled by CNC computer, when it is necessary to complete the same cutting work above, it must use the pre-programmed processing program to carry out the action, CNC CNC machine tool it no longer needs or reduces the manual technology of workers, it has obvious advantages compared with ordinary machine tools, it minimizes the impact of human factors on the product, and gives full play to the biggest advantage of high precision and high speed of CNC machine tools.

From ordinary machine tools to CNC machine tools must pass several thresholds, first, the cost has increased, buy the same machine tool increased by about 3-10 times. Second, the education level has improved, and the minimum education of workers and managers who operate and use CNC machine tools is higher than the secondary school level. Third, the product grade has been improved, and the high efficiency and high precision brought by the use of CNC machine tools force your product structure to develop in a higher direction.

Fourth, the level of enterprise management has been improved, due to the use of numerical control technology, then the corresponding internal management, tooling, cutting tools, measuring tools, raw materials, etc. will need to have a certain adaptability.

The popularization and application of CNC machine tools is also a sign of the national mechanization level.

CNC machine tools include CNC lathes and CNC punches, CNC lathes are not used in the same way as CNC punches, CNC lathes are used for chips, and CNC punches are generally used for sheet metal processing.

After the 1970s, the hardware circuit components were gradually replaced by a dedicated computer and called the computer numerical control system, which is generally a special computer and equipped with an interface circuit to realize the control of the action of multiple CNC equipment. Therefore, the current CNC is generally CNC (computer numerical control), and the concept of NC is rarely used anymore.

CNC machine tools include CNC lathes and CNC punches, the function of the lathe is turning operations, and the function of punching machines is stamping operations. Machine tool is a general term for turning, milling and punching machines.
