General transformation of multi-axis drilling machine drilling machin

General transformation of multi-axis drilling  machine drilling machin 

Cnc milling machine small and medium enterprises in product quality and  production efficiency are the need for a new increase. But the processing means is far from sufficient. Many small and medium enterprises with their actual technical state of equipment improvements, through strengthening its own. In order to self-development.Common drilling for single-axis machine tools, but the installation will become a multi-axis multi-axle box of the drill, transformation into a multi-axis drilling, we could greatly shorten the processing time, improve production efficiency.            

   Application of multi-axis machining ：

 Cnc milling machine According to statistics, in general machine  tools in the workshop in general, the average cutting time rarely exceeds 15% of total working hours. The remaining time is plug-in, loading and unloading the workpiece, exchange tools, operation tools, measurements, and clear the iron filings and so forth. Although the use of CNC machine tools can improve 85%, but the purchase of costly. In some cases, even if the high productivity, but the processing of the same components, the cost is not necessarily lower than the average machine. Therefore must be more to shorten the processing time. Different processing methods have different characteristics, the drilling process, the multi-axis machining is a small investment to increase productivity through effective measures. 

The advantages of multi-axis machining ：

Although it is not the first in automatic  multi-axis adjustable long line applications, but only limited to high-volume production. Even with the adjustable multi-axis head expanded the scope of use is still far from being able to meet the volume is small, hole complex requirements. In particular, as industrial development, large and complex multi-axis machining is even more compelling. For example, large-scale nuclear power plants in the water-wall tube plate condenser has 15000 ψ20 holes, if radial drilling machine processing, and simply drilling holes and countersink countersunk head is necessary to 842.5 hours, while also crossed hours 151.1 hours. However, if the 8-axis CNC machining floor drilling, drilling countersink holes as long as 171.6 hours, crossed is also simple, as long as 1.9 hours. Therefore, the use of numerical control of two axis, so that proper alignment tool processing location, combined with multi-axis machining can not only expand the range of processing, but also on the basis of improving the accuracy can greatly enhance the work efficiency, easy to quickly create original processing parts. Some analysis of large high-speed diesel engine with 30 kinds of box-shaped rod-shaped parts of the more than 2,000 drilling operations, 40% could be the automatic replacement of machines using two-axis spindle box, three-axis or four-axis multi-axis machining head, the average can be reduced 20% of the processing time. Machine Tool Exhibition in Paris in 1975 also reflected the multi-axis machining using more and more the trend.   

Multi-axis machining equipment ：

 Cnc milling machine  Multi-axis machining is the same time in a feed  processing a number of holes or simultaneously in many of the same or different processing of a workpiece on each hole. This will not only shorten the cutting time and improve accuracy, reduce fixturing or positioning time, and in the CNC machine tool is not necessary to calculate the coordinates, reducing the number of character blocks

and simplified programming. It can be processed using the following equipment: radial drillingvertical drilling, or upload multi-axis head, multi-axis drilling machine, multi-axis modular machine tool spindle box heart and automatic replacement of machines. May even be able to automatically adjust wheelbase by two or more of the spindle axle box, junction  All CNC vertical and horizontal table two directions of movement, processing a variety of round or oval-shaped hole group of one or several steps. Now the status quo in this regard to make a profile。
