1.Concept of the 5-axis machining center
5-axis machining center, also known as the 5-axis linkage machining center, is a kind of high science and technology content, high precision specially used for processing complex curved surface machining center, this machining center system for a country's aviation, aerospace, military, scientific research, precision instruments, high precision medical equipment and other industries have a pivotal influence.At present, the 5-axis CNC machining center system is the only means to solve the impeller, blade, Marine propeller, heavy-duty generator rotor, steam turbine rotor, large diesel engine crankshaft and so on.
5-axis linkage machining center has the characteristics of high efficiency and high precision, the workpiece can be completed a complex processing clamping.Can adapt to such as automotive parts, aircraft structural parts and other modern mold processing.5-axis machining center and pentahedron machining center is very different.A lot of people do not know this, mistakenly put the pentahedron machining center as a 5-axis machining center.5-axis machining center has X, Y, Z, A, C five axes, XYZ and AC axis formation of 5-axis linkage processing, good at space surface processing, specialshaped processing, hollow processing, drilling, inclined hole, inclined cutting, etc.And the "pentahedral machining center" is similar to the three axis machining center, but it can do five sides at the same time, but it can not do special-shaped processing, drilling holes, cutting inclined plane, etc.
2. The application prospect of five axis machining center
5-axis machining center is not only used in civil industries, such as wood mold manufacturing, sanitary repair, automotive interior accessories processing, foam mold processing, European style home furnishing, solid wood chair, etc., but also widely used in aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries.5-axis machining center is a kind of high-tech means, it makes impossible to become possible, all the space surface, special-shaped processing can be completed.It can not only complete the complex workpiece to complete the task of mechanization processing, but also can quickly improve the processing efficiency, shorten the processing process.
3, 5-axis machining center advantages
5-axis machining center advantage one is to be able to process the general three axis CNC machine tools can not be processed or it can not be completed once the processing of free surface.For example, the blades of aircraft engines and steam turbines, the propeller of naval ships, and other complex molds with special curved surfaces.Because the tool and Angle of the 5-axis machining center can be adjusted at any time during the processing process, you can avoid the obstruction of other tools and can complete all the processing at one time.
5-axis machining center in the premise of high effect, can also achieve free surface processing accuracy, and quality.For example, when three axis machine tool processing complex curved surface, to use the ball end milling cutter, its cutting efficiency is low, and the Angle of the tool can not be adjusted freely, so it is difficult to ensure the quality of the surface smoothness.But with five axis machining center machine tool processing, because the Angle of the tool can be freely adjusted, you can avoid the above situation, so as to obtain higher cutting efficiency and high quality processing surface quality.
5-axis machining center can be divided into: 5-axis linkage machining center, 5-axis CNC machining center, 5-axis precision machining center, 5-axis high-speed machining center, 5-axis CNC machining center, small 5-axis machining center, high-precision 5-axis machining center, 5-axis machining center machine tool, vertical 5-axis machining center.
Five axis machining center in the deeper, more steep cavity machining, can through the workpiece or the additional rotary spindle head and swing to create the best process conditions for the machining of the vertical milling cutter, and avoid cutting tools and tool holder and the cavity wall collision, reduce the cutter when processing the jitter and the risk of tool breakage, thus to improve the quality of the surface of the mold, the processing efficiency and cutting tool durability.
5-axis machining center through the use of shorter tools, can complete the processing of the whole parts at one time, do not need to load the card again or use the same kind of 3 axis processing in the need for a long tool, and can be delivered in a short time, the surface quality of the parts is more ideal.
The technology of the 5-axis machining center eliminates the need for multiple debugging and loading of the workpiece at complex angles.This not only saves time, but also greatly reduces the error, and saves the installation of the workpiece in place required fixtures and other expensive costs.
In addition, the 5-axis machining center enables the machine to process complex parts that are not possible by other methods, including drilling, cavity recesses, and taper machining that are commonly required on complex surfaces
