Glass Tube End Polishing Machine

Product Overview

The SM-J89 Glass Tube End Polishing Machine is designed for fire-polishing the ends of small to medium diameter glass tubes. Unlike the SM-J11 which handles large-diameter tubes, the SM-J89 specialises in the smaller tube diameters used in ampoule production, glass straw manufacturing, capillary tube finishing, and specialty glass accessories where a clean, smooth tube end is required for product quality and user safety.

The machine applies precise flame energy to the tube end, creating a smooth, rounded profile that eliminates sharp edges from the cutting process. This is an essential finishing step in glass ampoule production, glass straw manufacturing, and any application where the tube end is exposed to direct handling or use.

The SM-J89 features automated tube feeding and polishing with consistent flame parameters, ensuring uniform end polish quality across high-volume production batches.
