外文资料翻译GENERAL TRANSFORMATION OF MULTI-AXIS DRILLILNG MACHINE DRILLING MACHINEAt present, China`s small and medium enterpries in product quality and production efficiency are the need for a new increase. But the processing means is far equipment. 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, tuansformation into a multi-axis drilling, we could greatly shorten the processing time, improve production efficiency. Application of mlti-axis machining: 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 productivity through effective measures.The advantages of multi-axis machining: Although it is not the in automatic multi-axis adjustable long line applications, but only limited to high-volume production. Even with the adjustable muti-axis head expanded the scope of use is still far from being able to meet the volume is small, hole comple requiements. In particular, as industrial development, large and volume muti-axis machining is even more compeling. For example, large-scale nuclear power plants in the water-wall tube plate condenser has 15000 20 holes, if radial drilling machine processing, and simply drilling holes and countersink countersunt head is necessary to 842.5 hour
