The advantages of applying five axis CNC machining technology to robot parts processing

In the aerospace industry, aircraft, rockets, satellites, etc. have extremely high precision requirements, and any manufacturing defects can lead to system failure or even serious consequences. The introduction of five axis CNC machining technology has significantly improved machining accuracy. Currently, the robotics industry is becoming an important growth point for CNC precision parts processing enterprises. With the increasing application of robots, the demand for high-precision machining of robot precision parts continues to rise. The new five axis machining technology is not only applied to unmanned aerial vehicles and CNC milling parts, but also widely used for five axis machining of key robot parts.

Five axis machine tools can process complex curved parts that three-axis machine tools find difficult to complete, such as robot joints, reducer housings, end effectors, etc. Robot CNC precision parts require extremely high precision, and five axis machine tools can fully meet this demand. At present, we have German imported Demage five axis linkage, precision 3-axis/4-axis/5-axis equipment, and turning milling composite production equipment. For parts with complex geometries and tight delivery cycles, five axis CNC machines demonstrate excellent flexibility and processing efficiency. We can assist clients in translating design concepts into actual products, covering rapid prototyping manufacturing to final parts for safety critical applications. Based on our four axis and five axis milling capabilities, we are able to provide high-precision parts with complex geometric features.

Common spare parts for robots include:

Moving parts, transmission parts, dexterous hand components, robot body parts, robot joints/structural components, robot motor housing, robotic arms, robot aluminum alloy parts, reducers, end effectors, shell structural components, etc. Robot parts machining centers usually use materials such as aluminum, copper, stainless steel, etc. So, which types of robot parts are suitable for five axis machining?

Joints and structural components

Robot joints and body structural components usually have complex spatial geometric features, such as multi angle mounting surfaces, irregular surfaces, lightweight hollow structures, etc. The five axis machining center can complete milling, drilling, tapping and other processes on multiple surfaces with one clamping, effectively avoiding cumulative errors caused by multiple clamping, and significantly improving the dimensional accuracy and positional tolerance control level of key structural components such as joint shells and robotic arm linkages.

Transmission and motion components

Transmission components, such as gearbox housings and precision gearboxes, as well as various motion executing parts, require extremely high precision in fitting and surface quality. Five axis machining technology can achieve efficient precision machining of complex contours, especially suitable for parts with radial holes, end face distributed holes, or spatially staggered hole systems. For example, the mating surface between the rigid and flexible wheels of the harmonic reducer, as well as the bearing installation holes of the RV reducer housing, can all achieve higher coaxiality and positional accuracy through five axis linkage machining.

Agile hand and end effector components

The dexterous hand and end effector belong to highly integrated miniaturized precision components, including a large number of irregular parts, thin-walled parts, and microstructures. Five axis machine tools, with their excellent tool accessibility, can use short tools to cut into the machining area at the optimal angle, effectively reducing cutting deformation of thin-walled parts and ensuring consistency and reliability of small features such as finger joints, sensor mounting seats, and clamps.

Motor casing and heat dissipation structural components

The robot motor housing and integrated heat dissipation structure are usually made of aluminum alloy material, which requires precise matching between the internal cavity and the bearing seat, as well as efficient processing of the external heat dissipation rib plate and installation interface. Five axis machining technology can be combined with turning and milling composite equipment to complete turning, milling, drilling, and threading in one clamping process. While ensuring the concentricity of the motor housing and the integrity of the heat sink, it greatly shortens the process flow cycle.

Alien and Spatial Surface Parts

For robot components with complex spatial surfaces, inclined features, or free-form surfaces, five axis linkage machining has significant advantages. Whether it is the irregular connecting plate at the end of the robotic arm or customized parts with complex flow channels or contour structures, five axis machine tools can achieve stable cutting through tool axis vector control, reducing manual polishing and repair workload, and ensuring consistency in mass production.

Based on Demage's five axis linkage, precision three-axis/four axis/five axis equipment, and milling and turning capabilities, we are able to flexibly develop the optimal process plan according to the different structures and material characteristics of robot parts. From rapid prototyping verification to batch stable delivery, five axis machining technology provides a solid guarantee for the accuracy, efficiency, and reliability of robot core components.
