A brief introduction to the machining structure of turning and milling

Turning-milling compound machining machine tool refers to a machine tool that can complete both turning and milling. It can be used as a lathe and milling machine. The current vertical machining centers and horizontal machining centers are combined machine tools for turning, milling, drilling and boring.

The current turning-milling compound machining machine tools mainly show two different types. One is a combination of different processing methods based on energy or motion patterns; the other is based on the principles of process concentration and mechanical processing technology. The main compound, turning and milling compound processing is one of the processing methods that have developed rapidly in this field in recent years.

Turning and milling combined processing: mainly used for milling. Only X; Y; Z three-axis linkage. The Z axis is usually the power axis. Spindle (horizontal; special machine tools are not in this example) turning-milling compound machine tool: also known as a five-axis dual-power head machining center.

Turning and milling compound processing is the main model of compound processing machine tools. In addition to the functions of CNC lathes, it can also complete surface milling, drilling, tapping, straight groove, spiral groove and tooth milling, etc. It has compound functions such as turning, milling and boring. It can realize the concept of a machining, clamping and clamping in time. carry out.

CNC machine tools that meet all of the following characteristics are turning and milling machine tools:

1. The spindle motor adopts a servo motor, which can link the rotation movement of the spindle with the feed movement.

2. In addition to the turret tool holder of the turning-milling compound machining lathe, at least one electric tool or an independent electric tool holder should be equipped.

The main advantage of turning-milling combined processing is to shorten the product manufacturing process chain and improve production efficiency.

Turning and milling combined processing can be equipped with various special tools. The new tool layout reduces tool change time and improves processing efficiency. Turning and milling combined processing can complete all or most of the processing procedures at one time, thereby greatly shortening the processing time. In this way, on the one hand, the production assistance time due to the replacement of the installation card is reduced, and the manufacturing cycle and waiting time of the tooling fixture are also reduced, which can significantly improve the production efficiency.

The machining efficiency of the combined turning and milling process can be used. The new CNC turning and milling center can be loaded with more special processing tools. The arrangement of the cutting tools is completely different from the traditional CNC machining machines in the past, which can reduce the tool change time and improve the processing efficiency. Turning and milling combined processing can complete all or most of the processing procedures at one time, thus greatly shortening the product manufacturing process chain.
