What is turn milling compound machining?
Turn-milling compound machining can be referred to as turning-milling . Turning and milling is an advanced cutting process that uses the rotary compound motion of the milling cutter and the workpiece to cut the workpiece, so that the workpiece can meet the customer’s requirements. Such as shape accuracy, position accuracy and the integrity of the machined surface. Turn-mill machining is not a simple combination of adding turn-mill machining on one machine tool, but uses turn-mill simultaneous or continuous motion to machine various surfaces. With the turn-mill service, customers can obtain CNC precision machined parts in a very short time and at a lower cost. This compound processing can also be applied to mass production
Why is mill-turn helpful?
Usually, turning and milling is carried out by turning and milling CNC machine tools. Turning and milling CNC machine tools are one of the main types of combined machine tools. Generally, many CNC milling services such as milling, drilling, tapping and slot milling can be realized on the basis of CNC lathes. The turning-milling CNC machine tool has the functions of turning, milling and boring, and a complete machining can be realized in one clamping.
What is a turning milling machine?
The movement of the turning-milling compound machine includes four basic movements: milling cutter rotation, workpiece rotation, milling axial feed and radial feed. According to the difference of the relative position of the workpiece rotation axis and the tool rotation axis, the turning-milling compound machining can be divided into axial turning-milling, orthogonal turning-milling and ordinary turning-milling. Among them, axial turning and milling and orthogonal turning and milling are the most widely used CNC turning and milling processes. Axial turning milling cutters can not only machine the surface of the outer cylinder, but also the surface of the inner hole, because the axes of rotation of the milling cutter and the workpiece are parallel to each other. Orthogonal turn milling is very efficient when machining outer cylinders because its milling cutter and workpiece rotation axes are perpendicular to each other. Orthogonal turn-mills can machine smaller diameter bores. When the surface of the outer cylinder is processed by orthogonal turning and milling, the longitudinal stroke is not limited, and it can even adapt to a large longitudinal feed.
What are the advantages of turning and milling?
1.Shortening of R&D or production cycle
Turning and milling services can help customers shorten the development cycle. With the application of turning-milling CNC machine tools, the manufacturing chain of products or prototypes is shortened, and production efficiency is significantly improved. Turn-milling machine tools can be equipped with a variety of special tools and new tool arrangements, which can reduce tool change time and improve processing efficiency. Turn-milling compound machining can realize all machining or most CNC parts machining in one clamping, which greatly shortens the manufacturing chain. In this way, the product can be completed in a very short production cycle. With a quick turnaround of a product or prototype, customers can gain a huge advantage during the R&D and production phases.
2.Improved accuracy
The precision of the product will be effectively improved. The clamping time of the turning and milling machine is greatly reduced, and the machining accuracy is significantly improved. Cumulative tolerances due to position changes are avoided because of the reduced clamping. At the same time, many turn-milling compound machines have online detection functions, which can realize in-situ detection and precision control of key data in the manufacturing process, thereby improving the precision of products.
3.Reduce production costs
Due to high production efficiency and reduced processing time, production costs are significantly reduced. In this way, CNC turning and milling services can help customers save a lot of money on production or rapid prototyping. On the one hand, mill-turn machining reduces auxiliary production time due to change-overs. On the other hand, mill-turn reduces the manufacturing cycle and waiting time of jigs and fixtures, which can significantly increase productivity. The high-strength integrated body design improves the gravity processing ability of difficult-to-cut materials. The turn-milling compound machine is usually equipped with an automatic feeding device, which performs continuous processing through automatic feeding to realize single-machine assembly line production. Production time is one of the major parts of the cost as it is related to labor costs. With reduced manufacturing time, customers can obtain products with low cost and high precision.
Application field
Generally speaking, customers will choose the turn-mill service for high-speed high-volume production of various small precision machined parts. Materials used range from brass to steel, aluminium, stainless steel and Teflon.
