Zero-gap Disc Machine

Zero-gap Disc Machine
Product Introduction:
The Zero-gap Disc Machine is a state-of-the-art surface finishing system designed for high-precision applications. At the heart of this machine lies the patented zero-gap technology, which enables deformation-free polishing, deburring, and mirror finishing of ultra-fine and ultra-thin workpieces—down to 0.08–0.1mm in thickness.
From watch components and jewelry to medical implants and aerospace parts, this machine delivers superior surface quality in significantly reduced cycle times.

Description
Technical Parameters

Core Working Principle

 

The machine utilizes centrifugal disc finishing technology. Workpieces and abrasive media are placed in a stationary process drum, while a rotating disc at the bottom generates high-speed centrifugal force, creating an intense toroidal flow.

This motion produces finishing forces 10–20 times greater than conventional vibratory systems, enabling rapid processing from heavy deburring to mirror polishing in a single machine.

Patented Zero-Gap System

 

Wet Zero-Gap System

Gap between rotating disc and stationary drum can be reduced to zero

Enables use of ultra-fine abrasive media (e.g., quartz powder) for superior surface finishes

Effectively prevents thin or delicate workpieces from becoming lodged in the gap area

Ideal for processing extremely thin workpieces as thin as 0.1mm without deformation

Dry Precision Gap System

Gap accuracy down to 0.05mm, formed by precision SIC ceramic rings

Ceramic seal ring bearing design maximizes service life

Superior Processing Efficiency

Centrifugal force delivers 10–20× higher efficiency compared to conventional vibratory systems, dramatically reducing cycle times and supporting high-volume continuous production.

Intelligent Control System

Equipped with Siemens PLC touchscreen control, allowing easy setting and storage of up to 5,000 processing programs covering speed, time, water/compound concentration, rinse cycles, and all other critical parameters.

Modular Design

Standard configuration supports 1–4 process drums, offering flexible capacity expansion options. The chassis is constructed from anodized aluminum profile, providing excellent corrosion resistance and easy integration of optional equipment.

Robust Construction

Manufactured with high-quality materials including hot-molded PU-lined process drums, ensuring durability and trouble-free operation. The ceramic/PU gap system reduces maintenance requirements.
