Household Glassware Machinery
Bench-top manual glass tube cutter for laboratory and small-batch use. Available in low table and high table configurations. Clean, consistent scoring for chip-free tube separation.
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-J30 Manual Glass Tube Cutter is a bench-top tube cutting tool designed for laboratory, workshop, and small-batch production environments. Available in low and high table configurations to suit different working preferences, the SM-J30 scores glass tubes cleanly and consistently for precise, chip-free separation.
Ideal for glassblowers, laboratory technicians, and small-scale glass processors who need reliable, repeatable tube cutting without the cost or footprint of a fully automatic machine. Every machine is built under Sea Melody’s ISO 9001:2015-certified quality management system.
