TBK Screen Polishing Machines: Technical Specifications and Series Overview
Overview of Water-Mill Polishing Technology
In the field of mobile device refurbishment, TBK screen polishing machines utilize water-mill injection technology to restore glass surfaces. This process involves the mechanical removal of scratches through grinding and polishing, rather than replacing the entire screen assembly. By using a combination of water, polishing powder, and precise friction, these machines can eliminate imperfections ranging from minor scuffs to deep scratches on mobile phones and watches.
The technology is designed to preserve the original electronic components of the device while restoring the aesthetic condition of the glass. The equipment operates by circulating liquid to cool the glass during the abrasion process, ensuring the safety of the device's internal components.
Categorization of TBK Polishing Equipment
The TBK product line is segmented by capacity and form factor to address different operational scales, from individual repair technicians to high-volume refurbishment factories.

Operational Considerations
When implementing these machines into a repair workflow, several technical factors apply across the TBK lineup:
-
Waterproofing: Regardless of the model (938, 938S, or 938F), devices must be waterproofed using UV glue or molds before entering the water-polishing cycle to prevent liquid damage.
-
Consumables: All models utilize similar consumables, including polishing powder (cerium oxide), waterproof glue, and oleophobic coating sprays post-polishing.
-
Versatility: These machines are capable of handling various glass substrates, including mobile phone screens and smartwatches, provided the correct molds are used to secure the device.
FAQs: TBK Polishing Equipment
Q1: What is the primary difference between the TBK-938S and the TBK-938F?
A1: The primary difference lies in capacity and motor technology. The TBK-938S is a single-station unit, whereas the TBK-938F is a dual-station unit capable of polishing two screens at once. Additionally, the 938F features a frequency conversion servo motor, which provides quieter operation and higher stability.
Q2: Does the TBK-938 Series require an external air compressor?
A2: No, the TBK-938 multi-station series features an all-in-one design with a built-in silent air pump and liquid circulation system, removing the need for external air compressors for the polishing function.
Q3: Can these machines remove deep scratches?
A3: Yes, TBK polishing machines are designed to remove both minor scuffs and deeper scratches. The process involves grinding down the glass layer to the depth of the scratch. However, they cannot repair cracked or shattered glass.
Q4: Is the TBK-938F suitable for a front-of-house retail environment?
A4: Yes, the TBK-938F is particularly suitable for retail environments due to its compact desktop size and the use of a servo motor, which ensures low-noise operation that minimizes disruption in customer-facing areas.
Q5: How many devices can the industrial TBK-938 series handle?
A5: The TBK-938 series is modular in its configurations, with models available to handle 2, 4, 8, or up to 16 devices simultaneously, depending on the specific model selected.
