1. Improve work efficiency. After turning and milling the CNC lathe, it can continuously process and produce, and at the same time, it can process and produce various precision instruments within a small range.Improve the accuracy of the instrument and standardization of production.
2, to provide online testing, CNC lathe can also provide online testing, can detect some unqualified parts or shaped parts, and greatly improve the efficiency of work.Therefore, CNC lathes play an increasingly important role in the workshop, providing practical advantages and benefits to consumers, but also improving work efficiency and saving resources.
3, security and stability, security and stability have also been well protected. When the operator or staff is operating, the risk is reduced and there is no need to worry about safety issues.Moreover, the overall cost performance of the CNC lathe is very high, as long as the maintenance and maintenance of the machine can improve the service life of the machine and equipment. Therefore, the overall cost performance of such a CNC lathe is particularly high.
The turning and milling compound machine tool is a fast-developing and widely used numerical control equipment in the composite processing machine tool. Machine tool compounding is one of the important directions in the development of machine tools. Compound machine tools include turning and milling composites,
Car milling and grinding compounding, milling and grinding compounding, cutting and 3D printing compounding, cutting and ultrasonic vibration compounding, laser and stamping compounding, etc., the purpose of compounding is to make a machine tool more versatile.
Multi-tasking can be done in one setup to improve machining efficiency and machining accuracy.
Compared with the conventional CNC machining process, the outstanding advantages of turning and milling composite machine tools are mainly reflected in the following aspects:
(1) Shorten the manufacturing process chain and improve production efficiency.
(2) Reduce the number of clamping and improve the processing accuracy.
(3) Reduce floor space and reduce production costs.
There are two main forms of machining for turning and milling: the contouring of the workpiece parallel to the tool axis; and the machining of the workpiece perpendicular to the tool axis.The contour contour turning and milling combined machining is similar to the machining of the inner and outer contours of the rotating workpiece by means of helical interpolation milling; while the face machining type turning and milling combined machining can only process the outer surface.Although the turning and milling complex machining looks very similar to turning, it is as simple as turning with a rotating milling cutter, but the two machining methods are fundamentally different.The cutting speed of turning and milling combined machining is determined by the speed of the milling cutter; the cutting speed different from turning is defined by the rotational speed of the workpiece. The speed of the workpiece in the turning and milling combined machining is only related to the feed.Turning and milling composite machining has its own application fields and advantages. The following are the main points.
First, the processing of non-continuous surfaces can lead to intermittent cutting, such as processing various grooves and clearing the roots. In classic turning operations, this operation can create impact loads that are not conducive to machining, resulting in poor quality of the machined surface and premature wear of the tool.
In the turning and milling combined machining, the tool used is a milling cutter, and the milling itself is interrupted cutting during the periodic change of the load.
2. When the material to be processed is long chip material. In turning, chip forming is a difficult task; finding the right chipbreaker for the turning tool is not an easy task.
Milling cutters for turning and milling combined machining produce short chips, which significantly improves the control of the chips.
3. Taking the crankshaft and the main shaft of the eccentric journal as an example, in the turning process, the eccentric mass of the workpiece such as the crankshaft neck and the eccentric cam can cause the unbalanced force to be generated, which adversely affects the machining.The turning and milling combined machining avoids such negative effects due to the low rotational speed of the workpiece.
The introduction of turning and milling composite machining in manufacturing not only solves the processing problem but also greatly increases the output. With relatively new machining methods, with the right modern machine tools and the right choice of cutting tools,
Will provide substantial productivity. Although CNC machine tools are widely accepted and used, the development of metal cutting machine tools is still too traditional, and specific machine tools are developed according to their respective functions such as turning, milling and drilling.
If the machining center of a rotating tool such as a clamping cutter or a drill bit can be integrated for CNC turning, the downtime can be reduced by reducing the number of times the workpiece is clamped and the number of times it is moved from this machine to another machine.Improve processing efficiency; this synergistic appeal has led to the revolution in the installation of rotary power heads on traditional CNC lathes, and thus the turning and milling composite machining. Today's modern multitasking machines have a B-axis that allows the tool to rotate and move.The advanced control system and cutting-edge CAM software allow the workpiece to complete the main machining tasks in one setup.
