Turn-milling composite machining is a way of mechanical processing, turn-milling composite machining is not simply the two processing means of turning and milling into a machine tool, but the use of turn-milling synthetic motion to complete all kinds of surface processing, is a new cutting theory and cutting technology produced under the condition of the greater development of numerical control technology; However, the real thing is often has two sides, the turn-milling compound has many obvious advantages, but also accompanied by some shortcomings, today the small editor of Santes CNC equipment to introduce you, turn-milling compound and processing advantages and disadvantages are what?
Turn-milling compound machining advantage
1, reduce the number of clamping, improve the processing accuracy
Dual-spindle turnmilling complex machine tools enable all the boring, turning, drilling and milling processes to be completed in a single clamping process, thus avoiding the hassle of repeated positioning and retooling, significantly shortening the workpiece production and machining cycle and avoiding the potential for increased tolerances due to repeated clamping. The reduction of clamping times avoids the accumulation of errors caused by the conversion of positioning reference. At the same time, most of the current turn-milling complex processing equipment has the function of online detection, can realize the key data in the manufacturing process detection and precision control, so as to improve the processing accuracy of products, high strength integration of the design of the bed to improve the gravity processing ability of difficult to cut materials, the machine is equipped with automatic feeding device, can realize automatic feeding to continuous, The basic realization of a single machine line operation.
2, reduce the floor area, reduce the processing cost
Compact and beautiful shape design, improve the use of space, maintenance and repair more convenient so that customers get satisfaction although the price of a single unit of turn-milling complex processing equipment is relatively high, but because of the shortening of the manufacturing process chain and the reduction of the equipment required by the product, as well as the reduction of the number of fixtures, workshop area and equipment maintenance costs, It can effectively reduce the cost of investment, production and management of overall fixed assets.
3, reduce product processing technology, improve processing efficiency
A variety of special tools can be installed new tool arrangement to reduce the tool change time to improve the processing efficiency, turn-milling complex machining can realize a clamping to complete all or most of the processing processes, thus greatly shortening the product manufacturing process chain. This not only reduces the auxiliary production time due to the change of the loading card, but also reduces the manufacturing cycle and waiting time of tooling and fixture. It can significantly improve the processing efficiency. The turn-milling composite processing completes a variety of processing processes through a single clamping part, shortens the processing time, improves the processing accuracy and processing efficiency. With turning, milling and other complex processing functions to achieve a clamping can complete the turning milling processing concept.
The defect of compound machining of turning and milling
1, turn-milling complex processing operation, it is difficult to master in a short time. Complex machine tool programming, the ability of the operator is higher, especially because of the domestic composite processing started late, the level of foreign language has certain requirements, so the operation of processing procedures to master the difficulty is greater, the new composite machine tool training time is generally relatively short, the operator only mastered a few parts, Some enterprises on the function of imported machine tools only developed 1/10 of the level, limited by the level of the operator can only process limited products. Without the corresponding management mechanism, it is difficult to attract operators to conduct in-depth research. The lack of personnel makes it difficult to solve the problems of machine tools once they occur, and foreign senior technicians have to be hired at high prices to repair them.
2, turn-milling compound machine tool structure is complex, high maintenance cost. The manufacturing of composite machine tools is a collection of advanced technology and precision parts, and the maintenance of them is better. Hydraulic oil and lubricating oil are used according to the regulations. Regular maintenance, maintenance, overhaul, in order to ensure the consistent accuracy of the machine tool to replace the worn parts in time, and the replacement parts are generally very high price, such as guide rail, bearings, etc., and all kinds of oil. Machine tools have high requirements for the environment, and the environmental temperature, humidity and cleanliness of the processing site are required. Traditional machine tools require much less.
3, turn-milling composite processing is not suitable for mass processing. Due to the high cost, mass processing makes the single product manufacturing cost is high, such as a large number of tools after the use of its grinding dressing have very high requirements. And the traditional machine tool design after a special fixture, a machine only processing one element, a skilled worker a day to repeat the same action to control the loading and unloading action processing time can achieve mass production.
