Tumbling Room
About This Tumbling Room Process
This video showcases the tumbling room process used in acetate eyewear manufacturing.
Tumbling is a critical finishing step where acetate frames and components are rotated inside specialized barrels together with polishing media.
At Viff Eyewear, the tumbling process helps achieve smooth surfaces, rounded edges, and consistent hand-feel, which are essential for premium acetate eyewear frames.
Tumbling Process in Acetate Frame Manufacturing
During the tumbling process shown in this video, acetate frames go through:
Placement into rotating tumbling barrels
Controlled tumbling time and speed
Use of polishing media for surface smoothing
Preparation for later hand polishing and finishing
This process removes machining marks and sharp edges created during CNC cutting and shaping.
Why Tumbling Matters for Acetate Eyewear Quality
Proper tumbling significantly affects the final quality of acetate eyewear:
Improves surface smoothness and touch feeling
Rounds edges for better wearing comfort
Enhances visual consistency before polishing
Reduces manual polishing time while improving results
For OEM and ODM eyewear programs, controlled tumbling ensures consistent finishing quality across production batches.
Controlled Tumbling for Consistent Manufacturing Results
Tumbling is not a one-size-fits-all process.
Different frame designs, acetate thicknesses, and color patterns require adjusted tumbling parameters, including time, media type, and rotation speed.
This video reflects how Viff Eyewear applies process control and experience to achieve reliable results at scale.
Tumbling as Part of an Integrated Finishing Workflow
As a professional OEM and ODM eyewear manufacturer, Viff Eyewear integrates tumbling into a complete finishing workflow:
CNC machining and shaping
Tumbling and surface smoothing
Hand polishing and detailing
Spray painting and final finishing
This integrated approach ensures each acetate frame meets both aesthetic and functional requirements.
