More and more customers will choose the fourth axis when purchasing CNC machining machines.
1——Achieve high-precision processing of spatially complex curved surfaces
A:The four-axis CNC machining center makes the processing of space curved surfaces possible by introducing a rotation axis, thereby greatly improving the processing accuracy, quality and efficiency of free space curved surfaces.
. The core of this technology lies in the high degree of integration and optimization of machine tool control systems, servo drive systems and mechanical structures. Through precise programming and control systems, machine tools can achieve micron-level processing accuracy to meet the processing needs of various high-precision parts. It is suitable for polyhedral parts, spirals with rotation angles (such as cylindrical oil grooves), spiral grooves, Processing of complex parts such as cylindrical cams and cycloids.
B:It can process different workpieces, including those that cannot be processed by three-axis machining machines or that require too long clamping. For example, long-axis surface machining can be completed with a four-axis rotary table, thus expanding the machining possibilities.
C:At the same time, the four-axis CNC machining center has flexible and diverse processing methods, including positioning processing and linked processing modes. Positioning processing means that before the actual cutting of the workpiece, the rotation axis of the machine tool is rotated to a fixed orientation, and then the actual cutting begins. Simultaneous machining means that during the actual cutting process of the machine tool, a rotating axis simultaneously participates in the movement of the X, Y and Z axes of the machine tool. The choice of these processing methods depends on the specific processing needs and workpiece characteristics.
