Household Glassware Machinery
Glass bead cutting machine (SM-J69B) — a glue-free, gas-free diamond-blade dry cutter for small glass beads (≤2.3 mm) and capillary tubes. 1.7–3.8 mm, 200–370 kg/24h.
A pneumatic glass bead cutting machine is a machine that cuts glass bead and capillary tubing into short, uniform beads with clean, flat ends, using pneumatic clamping instead of the traditional glue-bundling process — no glue fixing and no gas flame required.
The SM-J69B Automatic Glass Bead & Capillary Tube Dry Cutting Machine uses a high-speed pneumatic pipe clamping design to cut glass tubes into uniform beads and short segments without any glue, adhesive, or LPG gas supply. The result is a cleaner, more eco-friendly cutting process with low energy consumption and a very low failure rate.
Particularly well-suited for glass beads under 2.3mm diameter, the SM-J69B delivers consistent output of 200–370 kg per 24 hours with approximately 5% material loss. After manual loading of tubes into the feeding tray, the machine runs fully automatically. Need higher output? For a higher-capacity, PLC-controlled machine (480–800 kg/day), see the SM-J69A Automatic Bead Cutting Machine. Every machine is built under Sea Melody’s ISO 9001:2015-certified quality management system.

The machine handles glass tubes from 1.7mm to 3.8mm in diameter. It is especially optimised for bead sizes under 2.3mm, where it delivers the highest accuracy and output.
Yes. The SM-J69B is a diamond-blade dry cutter. Combined with chuck clamping, it needs no glue, gas, or water — giving clean cuts with about 5% material loss and low running costs.
The SM-J69B is glue-free and gas-free and is purpose-built for small glass beads (≤2.3 mm), cutting about 15–25 seconds faster per batch. The SM-J69A uses adhesive powder and offers higher daily volume (480–800 kg/day, 212 tubes per batch) for large-scale production.
No — the SM-J69B is a dry cutting machine. It requires no LPG, natural gas, or adhesive of any kind. This makes it more economical to run and significantly cleaner than traditional wet or flame-cutting methods.
Output is 200 to 370 kg per 24 hours when cutting at L1.8mm. Actual output varies depending on tube diameter, cut length, and operating speed.
Material loss is approximately 5%, which is low compared to alternative cutting methods. This contributes to better raw material utilisation and lower production costs.
