In the overall trend of maintaining process concentration and eliminating (or reducing) the reinstallation and positioning of workpieces, composite processing allows more different processing processes to be combined on one machine tool, thereby reducing machine tools and fixtures, eliminating handling and storage between processes, improving workpiece processing accuracy, shortening processing cycles, and saving operating area.

Turning and milling composite machine tool is an advanced cutting method that uses the combined motion of milling cutter rotation and workpiece rotation to complete the cutting process of the workpiece, so as to meet the requirements of shape accuracy, position accuracy, and machined surface integrity of the workpiece. The turning and milling composite machine tool is not simply combining the two processing methods of turning and milling into one machine tool, but uses turning and milling composite motion to complete various surface processing. It has the following characteristics:

1. High precision: avoids human error and machine tool errors caused by scattered processes;

2. Rate: Effectively reducing production preparation time and improving machine tool utilization rate;

3. Cost reduction: It can achieve dual spindle operation simultaneously, reduce the number of machine tools, making it easier to plan production, saving investment costs and workshop space.

The motion of a turning milling composite machine tool includes four basic movements: milling cutter rotation, workpiece rotation, milling cutter axial feed, and radial feed.

According to the different relative positions of the workpiece rotation axis and the tool rotation axis, turning and milling composite machine tools can be mainly divided into axial turning and milling, orthogonal turning and milling, and general turning and milling. Among them, axial turning and orthogonal turning and milling are two widely used types of turning and milling. Due to the parallel rotation axis between the milling cutter and the workpiece, axial turning and milling can not only process the outer cylindrical surface, but also the internal control surface energy. Due to the perpendicular rotation axis between the milling cutter and the workpiece, orthogonal turning and milling cannot process the internal control when the inner hole diameter is small. However, when processing the surface of the outer cylinder, the longitudinal stroke of the milling cutter is not limited and a larger longitudinal feed can be used. Therefore, the efficiency is higher when processing the surface of the outer cylinder.

It effectively solves the problem of complex, precise, small batch, and multi variety parts processing. It is a flexible and efficient automated machine tool, representing the development direction of modern machine tool control technology, and is a typical electromechanical integrated product.

High efficiency CNC lathes are the introduction of computers on the basis of ordinary lathes, which use computers to control the operation of machine tools, achieve mechatronics integration, and further improve the operating accuracy of machine tools. At the same time, multi axis linkage is achieved to complete the processing of complex workpieces. CNC lathes have gradually occupied an important position in the manufacturing industry with their five major advantages. So what are the factors that affect the efficiency of high-efficiency CNC lathes?

1. The application level of CNC machine tools is not high
CNC machining has been in use for a long time in China’s manufacturing industry. Although there are strict operating standards and good maintenance of CNC machine tools, the loss of accuracy itself is inevitable. In order to control the processing quality of products, we regularly inspect and repair CNC equipment, clarify the processing accuracy of each equipment, and clarify the processing tasks of each equipment. For parts processing factories that produce in large quantities, high-efficiency CNC lathes should strictly distinguish the use of rough and precision machining equipment, because rough machining pursues high speed, high removal rate, and low machining accuracy, while precision machining is the opposite, requiring high machining accuracy. However, the precision damage to equipment during rough machining is serious. Therefore, we designate equipment with a long service life and poor accuracy as specialized rough machining equipment, and new equipment and equipment with good accuracy as precision machining equipment, achieving a reasonable allocation of existing equipment resources and clear division of labor, reducing the impact of machine tools on machining quality, while protecting expensive CNC equipment and extending its lifespan.

2. The unreasonable use of CNC lathes for batch production, especially in large-scale production, requires improving machining efficiency and ensuring the stability of the machining process while ensuring machining quality, which is the basis for achieving good economic benefits. Choosing a simple tool change method during batch machining of CNC turning is an effective way to reduce tool change assistance time, reduce machine wear, and lower machining costs. Improving the tool change point setting is one of the effective attempts to achieve this goal. Therefore, in terms of fixture selection, tool routing arrangement, tool arrangement position, and usage sequence, it is necessary to conduct detailed analysis and optimization design, improve tool change point settings, reduce operating costs, and improve machining efficiency.

3. Weak programming skills
The efficiency of the program directly affects the work efficiency of the machine tool, so optimizing programming quality is an important method to improve the work efficiency of high-efficiency CNC lathes. Firstly, familiarize oneself with the instructions of the machine tool, fully develop the internal functions of the machine tool, and seek efficient programming and machining methods. Secondly, vigorously promote computer programming, strengthen computer cutting simulation, improve program reliability, and thus reduce or cancel the time spent debugging programs on CNC milling machines.

Composite machining tools such as turning milling composite, turning grinding composite, and milling grinding composite have emerged one after another with the changing requirements of part processing. The emergence of this type of machine tool has changed the layout and structure of traditional CNC machine tools, enabling one machine to be used for multiple purposes. The workpiece can be clamped in one go to complete all or most of the machining processes, thereby reducing the number of workpiece clamping times, improving machine tool processing efficiency, reducing the number of machine tools used, and saving energy.

Turning and milling composite machining machine tools are rapidly developing and widely used CNC equipment in the field of composite machining machines. For high-speed precision turning and milling composite CNC machine tools, the spindle system is an electric spindle structure, and the machining accuracy of the machine tool largely depends on the accuracy of the electric spindle system, and is affected by the position accuracy of the tool holder and the dynamic performance of the machine tool. Therefore, in the manufacturing and assembly process of turning and milling composite machine tools, how to improve the accuracy of the electric spindle system, improve the position accuracy of the tool holder, and improve the overall dynamic performance of the machine tool is the key to machine tool design. This article analyzes the factors that affect the machining accuracy of turning and milling composite machine tools from the following aspects, and proposes corresponding solutions.

1、 The accuracy of the electric spindle system

1. The indexing accuracy and accurate stopping accuracy of the electric spindle system

The indexing accuracy and accurate stopping accuracy of the electric spindle system of the turning and milling composite machining machine tool are important indicators for evaluating the spindle accuracy of the machine tool, and are important factors affecting the machining accuracy of the machine tool. In order to achieve high indexing accuracy and accurate stopping accuracy of the electric spindle system, CNC turning and milling composite machining centers internationally all use a built-in spindle type motor, which is assembled with the motor rotor to reduce the impact of intermediate transmission links on the spindle accuracy. During operation, the rotation of the motor rotor drives the spindle to rotate. The speed and position loops of the spindle rotation adopt high-precision feedback components to achieve full closed-loop control. The position signals collected by the feedback components are divided and processed by the CNC system, resulting in a spindle indexing resolution of 0.001 ° or less, thereby making the machine tool spindle system have high indexing accuracy and accurate stopping accuracy.

2、 Rotation accuracy of electric spindle system

The CNC turning and milling composite machining center is a high-precision machining machine tool, and the spindle group is a key component. The rotational accuracy of the spindle group directly affects the accuracy of the processed workpiece.

To ensure high rotational accuracy of the spindle group, a series of process measures have been taken in the electric spindle system, including the connection between the spindle and the motor rotor, the fit between the stator sleeve and the spindle box, and the fit between the two ends of the spindle and the bearing group

1. Before assembling the electric spindle, ensure the accuracy of the spindle box hole, and ensure that the roundness, dimensional tolerance, and coaxiality of the front and rear bearing holes of the hole are within the required range; The radial runout of the spindle journal, the coaxiality of the front and rear journals, and the radial runout and end face runout tolerances of the spindle end are all controlled within 0.002mm.

2. During assembly, grind the spindle housing hole according to the size of the outer ring of the bearing, and strictly control the fit tolerance with the outer ring of the bearing within the specified range; The motor rotor of the electric spindle adopts special assembly techniques with the spindle.

When rough milling, choose a smaller milling cutter diameter because the cutting force is large during rough milling. Choosing a smaller diameter milling cutter can reduce the cutting torque. When precision milling with CNC machine tools, it is best to choose a larger milling cutter diameter that can accommodate the entire width of the surface to be machined, in order to improve the precision and efficiency of T machining. When the machining allowance of the machine tool is large and uneven, the tool diameter should be selected to be smaller, otherwise, the machining quality of the workpiece will be affected due to the deep tool marks caused by hanging the tool.

High speed steel end mills are mostly used for machining protrusions and grooves, and are generally not used for machining rough surfaces – because the hardened layer and sand inclusions on the rough surface can accelerate tool wear.

When processing rough surfaces or rough holes, end mills or corn milling cutters with cemented carbide inserts can be selected for strong cutting.

When processing the peripheral contour of flat workpieces, end mills C are often used.

In order to improve the precision of groove width and reduce the number of tool changes, a milling cutter with a diameter 7 wider than the groove can be used during processing. First, the middle part of the groove is milled, and then the tool radius compensation function is used to mill both sides of the groove.

When processing three-dimensional curved surfaces or variable bevel contour shapes, ball end milling cutters, circular milling cutters, drum milling cutters, conical milling cutters, disc milling cutters, etc. are often used.

When the machining allowance is small and the surface roughness requirement is high, surface milling cutters with cubic boron nitride or ceramic inserts can be selected to enable high-speed cutting of the machine tool.
