Three-axis machining is processed by linear feed axes X, Y, and Z. Used for general curved surface processing.
3-axis machining
The three-axis machining center is actually what we usually call the machining center. The machining centers are divided into three-axis machining centers, four-axis machining centers, and five-axis machining centers. These are the vertical machining centers we often see and use. There are also some six-axis, seven-axis, eight-axis, nine-axis, etc., but these machine tools are not our commonly used machining centers. Three-axis machining centers, as the name suggests, only have three axes, XYZ axes, we Generally speaking, machining centers, computer gongs, and CNC milling machines are all three-axis.
The three-axis machining center is a common and commonly used machining center. The three-axis machining center is also called a three-axis linkage machining center. It can realize machining by coordinating the movement of three axes at the same time. The price of the three-axis machining center is also the machining center. The cheap ones inside, we usually use a three-axis machining center or a four-axis machining center for processing. The effective processing surface of the three-axis machining center is the top surface of the workpiece, and the horizontal machining center can only complete the four-sided machining of the workpiece with the help of the rotary table. The current machining center is developing in the direction of five-axis control, and the machining of the pentahedron can be completed in one clamping of the workpiece. If the five-axis linkage CNC is configured, it can also perform high-precision machining on complex spatial surfaces. The choice of three-axis machining center or four-axis machining center or five-axis machining center is mainly based on our products. If the product only processes one surface We usually choose three-axis machining centers.
The three-axis machining center is divided into vertical and horizontal. The vertical three-axis machining center can effectively process only the top surface of the workpiece. Even the horizontal three-axis machining center can only process four workpieces with the help of the rotary function of the worktable. It is impossible to process some complex surfaces like a five-axis machining center. It can be said that almost all workpieces that can be processed by a three-axis machining center can be processed by a four- or five-axis machining center, but the three-axis workpiece that can be processed by a four- or five-axis machining center may not be processed.
Although the range of workpieces that can be processed by a three-axis machining center is very limited, its price is relatively cheap compared to four-axis and five-axis machining centers. Therefore, when the workpiece only needs a three-axis machining center to complete the task, when you only need to buy a three-axis machining center, there is no need to spend more money to buy a four-axis or five-axis machining center, although the four-axis and five-axis can process workpieces More, but there is no way to make the invested capital achieve good returns, and the functions of the machine tool are not used.
General cavity molds can be processed by three-axis. machining characteristics: The direction of the cutting tool remains unchanged during the movement along the entire cutting path. The cutting state of the tool tip cannot be perfect in real time.
3-axis machining method
The two rotating axes fix the cutting tool in an inclined position first, and then perform machining by the feed axes X, Y, and Z. This kind of machine tool is also called a positioning five-axis machine tool, which can be programmed and processed using Siemens' CYCLE800 function. CYCLE800 is a static plane conversion, which can define a rotating work plane in space through 32-axis machining (such as a rotary head or a rotary table). In this work plane, 2D or 3D machining operations can be programmed. 3 Positioning machining is suitable for plane machining.
machining characteristics: The rotary axis always rotates to the position where the machining plane is perpendicular to the tool axis for machining, and the machining plane remains fixed during machining.
