Compound processing is one of the current processing technologies in the field of mechanical processing. It is an advanced manufacturing technology. Compound processing is to realize several different processing technologies on a machine tool. Compound processing is the most widely used and most difficult, which is Turning-Milling compound processing. The Turning-Milling compound machining center is equivalent to the combination of a CNC lathe and a machining center.

brief introduction

Turning-milling compound machine tool is the fastest developing and most widely used numerical control equipment in compound machine tool. Machine tool compounding is one of the important directions of machine tool development. Composite machine tools include turning-milling, turning-milling-grinding, milling-grinding, cutting and 3D printing, cutting and ultrasonic vibration, laser and stamping, and many other forms. The purpose of compounding is to make a machine tool multi-functional, can complete multi-tasks at one time, improve processing efficiency and accuracy.

advantage

Compared with the conventional NC processing technology, the outstanding advantages of compound processing are mainly manifested in the following aspects.

(1) To shorten the manufacturing process chain and improve production efficiency. Turning-milling combined processing can complete all or most of the processing procedures in one loading, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistant time caused by the change of fixture is reduced, on the other hand, the manufacturing cycle and waiting time of fixture are also reduced, which can significantly improve the production efficiency.

(2) Reduce clamping times and improve processing accuracy. The reduction of loading times avoids the accumulation of errors caused by the transformation of positioning datum. At the same time, Turning-Milling composite processing equipment mostly has the function of on-line detection, which can realize in-situ detection and precision control of key data in manufacturing process, thereby improving the processing accuracy of products.

(3) Reduce the area occupied and the production cost. Although the single price of Turning-Milling compound processing equipment is relatively high, the cost of total fixed assets investment, production operation and management can be effectively reduced 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 area and equipment maintenance costs.

Characteristic

1. Turning-milling compound machining center uses high-precision built-in spindle;

2. Free-moving operation panel improves operation efficiency;

3. The machine mainly produces various small parts and complex parts in large quantities for high-speed and diversified processing.

4. Especially the slender and complex process can be processed and formed at one time, and the automatic feeding device can be configured to improve the efficiency.

5. Material details: Cutting, copper, iron, aluminum alloy, stainless steel, Teflon and other materials.

Development status

Most of the Turning-Milling combined processing is completed on the turning center, while the general turning center only changes the common turret tool holder of NC lathe into the turret tool holder with power cutter, and the spindle increases the C-axis function. Because of the restriction of turret tool holder structure and shape size, the power of power head is small, the speed is not high, and the larger tool can not be installed. Such turning centers are mainly turning, and the functions of milling and drilling are only to do some auxiliary processing. The high cost of power tool holder causes the high cost of turning center. The price of domestic tool holder is more than 100,000, and that of imported tool holder is more than 200,000. The average user can not afford it. Most of the economical Turning-Milling composites are XZC axes, which add a rotating C axis to the chuck to realize the basic milling function.

There are many kinds of turning and milling compound machining center equipments on the market, such as WFL, DMG, Dalian machine tool, Taiwan Taiyu precision machine, DOOSAN (Doushan machine tool), etc. The well-known software of turning and milling compound on the market is edgecam, UG NX and so on.
