CNC Machining Parts For A Compact Neck Massager

Manufacturing Challenges

The neck massager had a compact internal structure, leaving limited space for machining and assembly.

Several features required careful control, including:

Precise mounting holes for internal components
Flat and accurate mating surfaces
Consistent wall thickness on machined housing sections
Smooth edges and controlled surface appearance
Dimensional consistency between mating components

For compact consumer products, even a small dimensional deviation can affect assembly. Our engineering team reviewed the drawings and 3D models before machining to identify potential manufacturing issues and determine suitable machining processes.

CNC Machining Process

Depending on the geometry of each component, we used CNC milling and multi-axis machining to produce the required features.

For aluminum parts, CNC machining provided a good balance between weight, strength, machining efficiency, and surface quality. Complex pockets, mounting holes, slots, and curved profiles could be produced directly from the customer's CAD files.

Where tighter positional relationships were required, machining operations were planned carefully to maintain the relationship between critical holes, reference surfaces, and assembly features.

After machining, parts went through deburring and surface finishing according to the project requirements.

Surface Finishing

For consumer products, appearance is almost as important as dimensional accuracy.

Depending on the component and final application, available finishing options can include:

Anodizing
Bead blasting
Brushing
Polishing
Laser marking
Custom surface finishing

The finishing process was selected according to the material, appearance requirements, and intended assembly environment.

Quality Control

Before shipment, finished components were inspected against the customer's drawings and specifications.

Our inspection process focuses on critical dimensions, hole locations, mating surfaces, overall geometry, and surface condition.

For precision components, inspection methods can include calipers, micrometers, height gauges, and CMM measurement according to the part requirements.

This helps ensure that machined components remain consistent and ready for assembly.

Result

The CNC-machined components provided the customer with accurate structural parts for the neck massager development project.

By combining CNC machining, finishing, and dimensional inspection, Jingcheng Dingyi helped support the transition from CAD design to manufacturable components while maintaining the dimensional and appearance requirements of the product.

The project also demonstrates the flexibility of CNC machining for compact consumer products where customized geometry, low-volume production, and fast manufacturing response are important.
