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 J19B5 Glass Processing Lathe is designed for the thermal processing of glass and quartz tubes from φ160mm to φ420mm in diameter. It is a highly versatile machine suited to multiple processing procedures including sealing, shaping, docking, internal connection, side connection, and flanging, making it one of the most capable mid-range lathes in the J19B series.

Manufactured to customer requirements, the J19B5 provides a stable rotating platform and strong versatility for workshops that need to handle a broad range of glass processing tasks in a single machine. Every lathe is built under Sea Melody’s ISO 9001:2015-certified quality management system.
