With the continuous development and advancement of the current social economy, the development of the social engineering industry has begun to have urgent needs, and the requirements for precision parts processing have also begun to be higher. Due to its own design advantages, CNC lathes can be compared with traditional CNC lathes. Significantly reduce the number of feeds and improve processing efficiency. For many parts with a length of about 180, the full length of the parts can be completed at one time. It can be said that because of the relatively good quality and performance of CNC walking center lathe equipment, the sales volume in the sales market is also relatively high.

In the processing of parts, for those small parts like bars, which need to be processed at one time, and these parts need to be processed in batches, in most cases, CNC centering lathes are also used. Because it can turn many small parts at one time without stopping the spindle.

The Development of CNC Lathe

Numerical control centering lathe originated in the 1700s. The early centering lathe was called a “little pendulum” in the industry. It is an indispensable tool in the watch industry. Due to the rapid development of specialized CNC machine tools for processing watch parts, the early The core lathe is small in size and light in weight and is favored by companies in the watch industry and independent watchmakers. It has gone through several centuries from the original clock lathe to the current core CNC lathe.

The full name of the center-moving lathe is a center-moving CNC lathe, and it can also be called a moving headstock type CNC automatic lathe or a slitting lathe. It is a precision processing equipment that can complete compound processing such as turning, milling, drilling, and engraving at the same time. The CNC centering lathe is a relatively advanced production and processing machine, which was originally invented in Switzerland and used for processing needs in the military industry. The country began to introduce them, and the CNC walking core lathe began to develop continuously in China in 1990.

CNC centering lathe has a qualitative leap in processing efficiency and accuracy compared to CNC lathes. Because the structure of CNC centering lathes is different from traditional CNC lathes, the processing efficiency and machining accuracy of CNC centering lathes are higher than those of CNC lathes. . There are many types of CNC centering lathes. Here are classified with or without guide bushes. They can be divided into guide bushing centering lathes and guide bushing centering lathes. The former is suitable for processing long and thin shaft parts, and the latter is more suitable for processing thin and short parts. Pieces.

Design advantages of CNC core lathe

The current CNC centering lathe tool does not need to rotate and switch the tool, just move the props up and down, left and right, and the parts can be processed through the rotation of the spindle, and it can be fed multiple times. Therefore, compared with traditional lathes, CNC centering lathes can use the center guide bushing to make the products produced with higher precision, thereby achieving greater advantages in processing slender shaft parts. The following will briefly introduce the design advantages of CNC core lathes.

1. The trend of using high-speed built-in electric spindles for CNC walking lathes is becoming more and more obvious, and the spindle speed has reached 12,500 revolutions per minute.

2. Speed ​​and position loop feedback adopts built-in high-resolution grating or new components such as magnetism, which has higher control accuracy of rotation and feedback.

3. The opposing double-spindle cloth structure can complete all-sequence machining in one clamping, reducing the efficiency and machining accuracy problems caused by the secondary clamping of the workpiece, and improving the processing efficiency.

4. The greater advantage of CNC centering lathes is to process slender shaft parts. Compared with the tool type machine tool, when turning on a CNC centering lathe with a guide bush, the bar feeds axially through the center guide bush and the tool cuts. The point is close to the mouth end of the guide sleeve and has good rigidity, which eliminates the deformation of the bar under the cutting pressure of the tool and ensures the accuracy of the parts.

5. Abundant automatic configuration to achieve the goal of one-man multi-machine operation and management, in addition to traditional bar conveyors, chip conveyors, etc., such as long and short workpiece receivers, automatic tool setting instruments, intelligent workpiece identification, workpieces Automatic click detection, tool breakage detection, etc. have been successfully applied to the product, improving the automation and monitoring level of machine tools.
