5 Axis Machining
The development of the five-axis machining center and the turning-milling machine is for complex precision parts production, and the needs of machining parts with multiple angles or negative angles. For example, medical biotechnology parts, semiconductor parts, aerospace parts, special alloy parts and military industrial parts.Mold development for precision parts on a high precision 5-axis machining center.
Differences Between 3-Axis, 4-Axis and 5-Axis Machining
In the traditional three-axis or four-axis machining centers, some workpieces affect the machining due to the interference between the spindle, the workpiece and the cutting tool. At this time, the machining process needs to be changed: Remove the workpiece from the fixture, and continue the machining with the other fixture at another angle. Accumulated tolerances are prone to occur during this fixture replacement process. The five-axis machining centers and the turning-milling machines were born to avoid this situation. Its flexible controller can do multi-axis control, which complements the machining ability of the cutting tools in the machining blind area.
Type of Five-Axis Turning-Milling Machines
There are two types of multi-axis machine tools such as five-axis and turning-milling machines, etc. One is a five-axis which can do multi-angle machining; turning-milling which can do turning manufacturing, but both cannot do curved-surface machining. Five-axis five sided turning-milling machines can do both curved-surface machining and surface engraving. At present, the latest five-axis five-sided machine center can do curved surface machining by computer through CAD/CAM converting into industrial codes, especially for aerospace and molding industries. It is feasible to do complex and special angle parts machining with CNC five-axis five-sided milling machines.
Since the improvement of machine spindle horsepower, and a wide range one time machining with the large-scale face milling cutter, the size of the machining workpiece has gradually expanded. However, as the machining workpiece has become polarized, machining vendors will face more challenges in machining accuracy, tool properties and fixture design, as well as meticulous planning and integrated process.Small Amount of Customization and Capacity Allocation
The five-axis five-sided and turning-milling machine can complete the workpiece machining on the same machine tool, so there is no problem with the dismantling process. Therefore, it mainly provides high value-added workpiece machining on small-scale production and customized processing parts, such as precision workpiece proofing and high-precision complex parts machining. For general workpieces with production, it will be performed by splitting the process and using multiple machines for synchronous machining, to meet the customer's production requirements.
Automatic Loading and Unloading of Five-Axis and Turning-Milling Machine
WKPT has gradually built automation production lines, digitalization and intelligent machining equipment. After the five-axis and turning-milling machine has been imported, automatic loading and unloading system is included, too. Although the application of automatic loading and unloading of robotic arms is well established and reduces the workforce of mechanical operation compared with labor workforce. The automation design and development capabilities of WKPT in the past will be an excellent assistance when automation applied on post-machining and parts assembly.
Tool interference means that the cutting path of the tool performs unnecessary cutting (excessive cutting) on the workpiece during the machining process, which is called "tool interference".
