Three-Dimensional Milling Machine Technology Parameter
Three-dimensional milling machine technology is a kind of advanced machining technology. It can finish the multi-degree or complex three-dimensional contour of the parts in one kind of clamping. The three-dimensional milling machine is mainly used for high-precision machining of complex parts and mold machining, such as turbine blades, impellers, non-circular splines, etc.
Three-dimensional milling machine tool structure is mainly divided into four kinds: vertical, horizontal, gantry and non-pallet milling machine. Among them, the vertical three-dimensional milling machine is the first use of three-dimensional milling technology, and its mechanical structure is relatively simple. It is suitable for three-dimensional machining of small parts, such as turbine blades, impellers and other complex small parts. Gantry type milling is suitable for the machining of large and medium-sized parts, such as aircraft parts, car parts and other automotive dies.
The three-dimensional milling machine is distinguished from the ordinary milling machine in the spindle vertical direction alone. When the spindle is vertical, the three-dimensional milling process has two directions such as vertical and horizontal, and when the spindle is horizontal, it is also possible to guide the tool in multiple directions to perform three-dimensional machining.
The three-dimensional milling machine worktable of different models and different manufacturers have different characteristics, some of which can be used as fixed or removable steel platform or support surface. The X, Y and Z axes of the three-dimensional milling machine move relative to the workpiece surface, or the spindle moves relative to the spindle, thus realizing the three-dimensional programming path of the equipment.
In the three-dimensional milling machine, the tool change time corresponds to the time required to change the spindle head in the three-dimensional milling machine. In order to improve the efficiency of the machine tool, many three-dimensional milling machines are gradually equipped with automatic tool changers. In addition, the three-dimensional milling process should also use a variety of special tool structures that can be used for multiple processes. In the actual machining, the tool should be in a reasonable position so as not to interfere with or damage the clamping part.
The feed rate of the three-dimensional milling machine is related to the spindle speed and the number of teeth of the cutter. Generally, the feed rate is low, the number of teeth of the cutter is large, and the number of revolutions of the spindle is higher. The feed rate of the three-dimensional milling machine should be adjusted in accordance with the chip load and the strength of the workpiece.
In the process of three-dimensional milling, it is very important to choose a suitable cutting fluid for cooling and lubricating. This kind of liquid can effectively reduce the machining temperature and improve the surface quality and machining accuracy of the product. At the same time, in order to take full advantage of the three-dimensional machining capability of the three-dimensional milling machine, some three-dimensional machining professional software is required.
In summary, the three-dimensional milling machine technology parameter of the spindle speed, clamping type, tool change time, feed rate, cutting fluid and software selection are all important factors affecting the technological level of the three-dimensional milling machine. Therefore, it is necessary to pay attention to the selection and optimization of these parameters in the process of using the three-dimensional milling machine.
