Precision industrial machinery often depends on small mechanical components manufactured to controlled dimensions. Pins, bushings, shafts, sleeves, spacers and threaded components can play important roles in alignment, positioning, rotation, movement and assembly.
Although these components are often much smaller than the machines in which they are installed, dimensional accuracy and repeatable production can directly influence assembly consistency and equipment performance.
JUXIN provides custom CNC machining for pins, bushings, shafts, sleeves, spacers and threaded components, supporting OEM manufacturers across industrial machinery, automation, robotics, semiconductor equipment, medical equipment, electrical systems and automotive applications.
Our drawing-based manufacturing approach allows components to be produced according to customer-defined materials, dimensions, tolerances, threads and surface-finish requirements.

Custom CNC components may be used in:
Robotic mechanisms
Linear motion systems
Grippers
Automation fixtures
Sensor assemblies

Alignment systems
Fixtures
Structural assemblies
Motion systems
Instrumentation
Precision mounting systems
Depending on the equipment environment, engineers may specify stainless steel, aluminum, titanium, engineering plastics or other application-specific materials.

Medical and diagnostic equipment can also require customized mechanical components for internal assemblies.
Potential components include:
Precision pins
Bushings
Spacers
Shafts
Sleeves
Threaded components
Custom CNC machined parts
For these applications, engineers may evaluate dimensional accuracy, material compatibility, corrosion resistance, surface finish and assembly requirements.
JUXIN manufactures components according to customer drawings and specifications rather than applying a one-size-fits-all material or finish.
Material selection should be based on the mechanical, environmental and dimensional requirements of the finished component.
Potential materials include:

Copper and brass may be considered for components requiring specific electrical, thermal or machining characteristics.
Material selection should always follow the customer's application and engineering specification.
Titanium can be evaluated for specialized applications where low density, strength and corrosion resistance are important.
Availability and machinability should be considered when specifying titanium for custom CNC production.
Engineering plastics can be used for selected components where lightweight construction, electrical insulation or specific material properties are required.
The appropriate polymer should be selected according to the operating environment and engineering requirements.
For precision mechanical components, not every dimension necessarily requires the same tolerance.
