CNC Machining In Robotics Industry

Application Scenarios

Structural Component Machining

The structural components of robots need to be strong, rigid and robust. cnc machining technology is able to create complex geometries for the production of e.g. shoulder joints, elbow joints, wrist joints, gears, bearings, housing components and other small components such as special fasteners or brackets.

Gear Machining

Gears are important structural components in robots that are used to transmit rotational forces or slow down motors. cnc machining can accurately manufacture these complex gear shapes to ensure precise meshing between gears.

Modular Tooling

Modular tools are assembled through a series of universal building blocks that are adapted for common mechanical connections at the end of the robot arm. cnc machining allows for quick and easy tool switching, such as quickly switching from a gripper tool to a suction cup.

End-of-Actuator Machining

End of Arm Tooling (EOAT) is the interface between the robot's operating arm and its surroundings, performing the tasks for which the robot was designed.CNC Machining can produce various types of EOATs, including mechanical or electro-mechanical.

Custom Fixture Machining

CNC machining specializes in producing custom parts with high precision and quality. For example, custom fixtures such as assembly trays are critical to most robotic operations, holding parts in place or accurately positioning parts, which is often required when a robot picks up or places parts.

Motor Assembly Machining

Robots require motors to drive the movement of arms and joints. The motors themselves have a number of moving parts, many of which can be produced by CNC machining, such as machined housings, attachment brackets, bearings, and shafts.

Technical Advantages

Rapid Production

CNC machining technology allows for rapid production from small batches to single pieces, significantly reducing cycle times, and is especially suited to customized robotic components that require a quick response.


CNC machining maintains extremely high dimensional accuracy and surface finish, which is critical for precise fit and repeatability of robotic components.

Material Selection

CNC machining is available in a wide range of materials, including aluminum, titanium, and engineering plastics, which are commonly used in robotics manufacturing to achieve the required strength and stiffness.

Surface Finishes

CNC machining allows for the production of parts with extremely low surface roughness, which helps to reduce friction and improve the performance and longevity of robotic components.
