The machine, known as the center CNC lathe, is a kind of compound processing lathe, mainly used in the hardware industry, is a very high utilization rate of equipment. So, what is it like to go scheming? What are the principles and structures of the scheming machine? Next, Xiaobian for you to introduce in detail.

What are the principles and structures of the scheming machine

What are the principles and structures of the scheming machine

One, go the scheming

Driving machine -- full name of the center type CNC lathe, can also be called the main axle box mobile CNC automatic lathe, economic turn-milling compound machine tool or longitudinal cutting lathe. Belongs to the precision machining equipment, can simultaneously complete the turning, milling, drilling, boring, tapping, carving and other composite processing, mainly used for precision hardware, shaft type non-standard parts of the batch processing.

Go trying on the machining efficiency and machining accuracy than CNC lathes have a qualitative leap, as a result of biaxial configuration tool, greatly reduce the processing cycle time, by shortening the row of a knife and to the tool machine tool exchange time, multiple overlapping function tool, thread cutting shaft moving overlapping functions effectively, when the secondary processing of spindle dividing function directly, To realize the shortening of empty travel time. Chip cutting tool has been in the spindle and workpiece clamping parts processing, to ensure the machining accuracy is constant. At present, the largest machining diameter of the machine on the market is 38mm, which has a great advantage in the precision shaft processing market. This series of machine tools can be equipped with automatic feeding device to realize the full automatic production of a single machine tool, reducing labor cost and product defect rate. It is very suitable for mass production of precision shaft parts.

Two, the characteristics of the advantages of scheming

Compared with the conventional CNC machining process, the outstanding advantages of composite machining are mainly shown in the following aspects:

(1) Shorten the product manufacturing process chain and improve production efficiency. The turn-milling compound processing can complete all or most of the processing processes in one loading, thus greatly shortening the product manufacturing process chain. On the one hand, this reduces the production auxiliary time caused by the change of the loading card, and also reduces the manufacturing cycle and waiting time of the fixture, which can significantly improve the production efficiency.

(2) reduce the number of clamping, improve the processing accuracy. The reduction of card loading times avoids the error accumulation caused by the transformation of positioning reference. At the same time, most of the turn-milling compound machining equipment has the function of online detection, which can realize the in-position detection and precision control of the key data in the manufacturing process, so as to improve the machining accuracy of products.

(3) Reduce the floor area and reduce production costs. Although the single price of turn-milling complex processing equipment is relatively high, it can effectively reduce the investment of overall fixed assets, production operation and management costs due to the shortening of manufacturing process chain and the reduction of equipment required for products, as well as the reduction of the number of fixtures, workshop floor area and equipment maintenance costs.

Three, the principle of scheming

The working principle of

Go machine tool does not need to rotate switching tool, as long as the up and down around the move props can, through the rotation of the spindle to achieve the processing of parts, and can be repeatedly fed. Therefore, compared with the traditional lathe, the machine can pass the central guide sleeve way, so that the precision of the products produced is higher, so as to realize the elongated shaft parts processing has greater advantages.

Under normal circumstances, the machine is more suitable for processing long bar batch processing, which makes it not like the traditional cutter, can enter the large diameter single piece of processing operation, only suitable for 32mm and the following diameter processing. And in the material roundness requirements are also relatively high, because it needs to go through the whole spindle and chuck, guide sleeve and other parts, in addition to the straight line of the material also has relatively high requirements.

Four, go scheming structure

1, the main shaft

It can carry out many times of feeding work, and can move in any direction according to Z1 axis and C1 axis when hardness.

2, auxiliary spindle

When moving, it can move according to the direction of Z2, X2 and C2 axis, and can change and move freely in all directions. Its main function is to assist the spindle in processing and receiving materials. The subsequent processing of some products needs to be processed on the corresponding tool rest on the auxiliary shaft. In the processing of the use of the main shaft is separated from the special control channel, can realize the role of complementary intervention with the main shaft, in the actual use of the process of two axes are needed to be processed at the same time, this mode of operation can effectively shorten the overall processing efficiency of the product.

3, rest

The tool rest is divided into four parts, mainly turning tool, side power head, end face and deputy shaft end face direction of the fixed seat, next to explain.

The position of the turning tool is on the tool rest of the main shaft to be able to operate the groove, the outside diameter and other processes well. Side power is milling, drilling, attack processing. The end face and the fixed seat of the deputy shaft end face are mainly used for milling, drilling and attacking some components.
