Overview

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 (φ120–450mm) is designed for the thermal processing of glass and quartz tubes in the medium-to-large diameter range. It features linear guide rails with a dual-chain drive system for smooth, reliable longitudinal movement, and is particularly well-suited to circular blowing and sealing operations.

This variant of the J19B3 series covers φ120mm to φ450mm, complementing the standard J19B3 (φ100–480mm) with a dual-chain drive configuration optimised for circular blowing workflows. Every lathe is built under Sea Melody’s ISO 9001:2015-certified quality management system.

Frequently Asked Questions

How does this differ from the standard J19B3?

This variant uses a dual-chain drive system with linear guide rails, which provides particularly smooth longitudinal movement for circular blowing operations. The working range is φ120–450mm vs φ100–480mm on the standard model.

What is the dual-chain drive system?

The dual-chain drive uses two parallel chains running on linear guide rails to move the lathe headstock longitudinally. This provides more even force distribution and smoother movement than a single-chain or rack system, which is important for precision glass blowing.

Can this lathe process quartz?

Yes — it is compatible with both borosilicate glass and quartz. Quartz requires higher-temperature torch setups; please advise your material when enquiring.

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 be customised for special requirements?

Yes — Sea Melody can modify diameter ranges, drive configurations, and torch setups. Visit our Custom Orders page to discuss your project.

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.
