Overview

A glass tube cutting machine is a machine that cuts lengths of glass tubing into precisely sized sections, using a rotating tube feed and a controlled cutting action to deliver flat, chip-free cut ends across multiple tube diameters.

The SM-J27 Automatic Glass Tube Cutting Machine is designed for high-precision, high-speed cutting of glass tubes into uniform lengths for downstream ampoule forming, vial production, and laboratory glassware manufacturing. The machine feeds, scores, and separates glass tubes automatically, delivering clean, consistent cut ends with minimal operator involvement.

The SM-J27 is a core piece of equipment in glass tube processing lines, typically positioned upstream of ampoule forming or filling machines to supply pre-cut tube blanks at production line speed. Every machine is built under Sea Melody’s ISO 9001:2015-certified quality management system.

Frequently Asked Questions

What tube diameters can the SM-J27 cut?

The SM-J27 is compatible with standard borosilicate glass tube diameters used in ampoule and vial production. Please contact us with your specific tube dimensions to confirm compatibility.

Can the cut length be adjusted?

Yes — cut length is adjustable to suit different downstream ampoule or vial sizes. The adjustment is made through the machine’s parameter settings without mechanical tooling changes.

How clean are the cut ends?

The SM-J27 uses a score-and-separate method that produces clean, consistent cut ends with minimal chipping. For applications requiring flame-polished ends, it is typically paired with an oil burner or end-finishing machine downstream.

What is the lead time?

Standard lead time is 40 working days from order confirmation, as each machine is manufactured to order. For custom or modified machines, allow approximately 60 working days. Contact us for a specific timeline based on your requirements.

Can this machine be customised for special tube sizes?

Yes — Sea Melody can engineer modifications for non-standard tube diameters or cut length ranges. Visit our Custom Orders page to discuss your requirements.

What after-sales support is included?

Sea Melody provides 24/7 remote support with a 5-minute response time, online video commissioning, operation manuals, and spare parts supply. See our After-Sales Support page for full details.
