Household Glassware Machinery
Glass and quartz processing lathe for φ100–480mm diameter tubes. Linear guide rail drive for smooth movement. Suited to sealing, shaping, circular blowing, and butt jointing.
A glass processing lathe is a machine that rotates glass or quartz tube between two synchronized, precision-aligned chucks while a burner flame softens the material, letting operators join, seal, and shape cylindrical glassware with both ends held in accurate alignment throughout the operation.
The J19B3 Glass Processing Lathe is a medium-to-large diameter glass and quartz lathe designed for the thermal processing of tubes in the φ100mm to φ480mm range. It features a linear guide rail drive system for smooth, precise movement, making it well-suited to sealing, shaping, circular blowing, and bottom sealing operations.
Part of Sea Melody’s J19B series of universal glass lathes, the J19B3 is manufactured to customer requirements and is used in industrial glassware production, laboratory equipment manufacturing, and specialty glass fabrication. Every lathe is built under Sea Melody’s ISO 9001:2015-certified quality management system.

The J19B3 handles glass and quartz tubes from φ100mm to φ480mm. Sea Melody offers other models in the J19B series for smaller diameters — see our full glass lathe range for the complete coverage.
The linear guide rail provides smoother, more precise longitudinal movement compared to rack-and-pinion or chain drive systems. This is particularly beneficial for operations like circular blowing and sealing where consistent feed speed is critical.
Yes — the lathe supports both borosilicate glass and quartz. Quartz processing requires higher-temperature torch setups; please advise your material type when enquiring.
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.
