5軸加工と3軸加工の比較

Milling can obtain a good curved approximate surface. When using a ball-end tool for three-axis milling, the linear feed motion in the x, y, and z directions can ensure that the tool cuts to any coordinate point on the workpiece, but the direction of the tool axis cannot be changed. The actual cutting speed of the point on the tool axis is zero, and the chip space in the center of the tool is also very small. If these points are involved in cutting, the unfavorable cutting conditions will cause the quality of the machined surface to decrease, the blade wear will increase, and the machining time will be prolonged. So that high-grade tool materials are not fully utilized.

5 axis milling machining of turbine impeller

Before adopting 5-axis CNC machining centers, most turbomachinery manufacturers used 3-axis or 4-axis machine tools to process impellers, and most of them used point machining. あれは, every point on the blade surface is processed into a point by the tool tip. When the tool moves along the surface of the blade, it will leave some pits or residual sharp corners, and the height of these pits or sharp corners depends on the programming skills. Point processing is also a feasible method, but this method has some unavoidable disadvantages:

Difficulties in milling large blades of impellers

In the CNC machining of the impeller blades, the machining of large impeller blades is the most difficult. Mastering the measures to solve the processing difficulties of large blades has a very positive effect not only on the large blade itself, but also on the impeller moving blades, impeller stationary blades, guide impeller blades and impeller end blades.

3-axis and 5-axis drilling technology for aluminum parts

CNC machining holes in the solid part of the workpiece with a drill is called drilling. The drilling is rough machining, the achievable dimensional tolerance grade is IT13~IT11, and the surface roughness value is Ra50~12.5μm. Due to the long length of the twist drill, the small core diameter and poor rigidity, as well as the influence of the chisel edge, the drilling has the following technological characteristics:
