With the continuous improvement of our living standards, the research and development and production of high-end products are inseparable from the five-axis machining center, and the use of the five-axis machining center is also increasing. For example: automobile manufacturing, automobile model making, bathroom product processing, high-grade furniture manufacturing, etc.
Five-axis linkage means that in addition to controlling the three axes of X, Y and Z at the same time, it also controls the axes of A and C rotating around these linear axes, and Xingcheng controls the linkage of five axes at the same time. At this time, the tool can be set in any direction of space.
For example, the tool is controlled to swing around the axis and the "axis" at the same time, so that the tool always keeps perpendicular to the machined contour surface at its cutting point, so as to ensure the smoothness of the machined surface, improve its machining accuracy and efficiency, and reduce the roughness of the workpiece surface. Of course, a CNC machine tool with five linkage axes can't be simply called a five-axis machine tool. Similarly, a CNC system can control five axes, and it can't be called a five-axis CNC system. To judge whether a CNC machine tool is a five-axis machine tool, we must first look at whether it has RTcP function. RTCP is the abbreviation of "Rotationa1 Tool Center Point", which translates as "rotating tool center", and it is often slightly escaped as "around the tool" in the industry. The TCP function can directly compensate the space length of the spindle tool on the machine tool.
A five-axis CNC machining center is generally composed of a lathe bed and a control system. The spindle, workbench, frame and feed mechanism constitute the main part of the lathe bed, in which the size of the workbench, the stroke range of each axis and the motor power of the machine tool constitute the key characteristics and specifications of the machine tool, and become one of the important basis for selection.
The main advantages of five axes are:
1. The degree of automation is high, and most or all of the workpieces can be processed by one-time clamping, thus ensuring the machining accuracy of the workpieces and improving the machining efficiency;
2. The quality of the processed parts is stable;
3. Strong adaptability, high flexibility and good flexibility to processed parts.
The main advantage of woodworking CNC machine tool is that the auxiliary working time is short when processing the whole complex workpiece, which greatly shortens the adding time of parts and saves a lot of time and expenses for the research and development of new products in enterprises.
Choice of five axes:
Structural selection:
Five-axis machining centers are divided into gantry five-axis machining centers and fixed beam and fixed column bed moving five-axis machining centers according to different structures. With the continuous development of information technology and computer digitalization technology, the performance and efficiency of CNC machine tools are also constantly improving. At present, the high-grade CNC system has high efficiency and high precision, which is suitable for machining complex surfaces, but it requires good rigidity, high precision, good stability and fast response speed of CNC system for the whole machine tool.
The workbench of gantry five-axis machining center has a large bearing capacity, and it is not affected by the impact of upper and lower workpieces and other factors to interfere with the deformation of the machine tool. The advantage of * is that the workpiece can be clamped conveniently, and the actual effective length of the workbench can be fully utilized to process the workpiece, so it can process items with larger sizes, such as yacht bottom, wind, car impeller, car mold and so on.
The movable five-axis machining center of woodworking NC machine tool bed has the advantages of uniform table movement, low speed operation, good positioning accuracy, small traction, good accuracy retention, long service life and strong maintainability, but it is earthquake-resistant and impact-resistant.
Poor hitting ability. Therefore, the movable five-axis machining center is more suitable for the production of fine products such as handicrafts and molds.
