Rough Grinding (Arazuri) Worker (Glass Product Processing)
あらずりこう（ガラスせいひんかこう）
Industry & Occupation
Classification
Summary
A manufacturing job that performs rough grinding and polishing on glass products to adjust shapes, dimensions, and surface roughness.
Description
Rough grinding workers, in the glass product manufacturing process, remove excess parts from the raw form of the product and perform rough grinding operations to approximate the specified shape and dimensions. They use grinding machines such as grinders and sanders, as well as emery paper and buffs, to rough-finish the surface in preparation for subsequent detailed polishing processes. The work involves reading drawings and proceeding while confirming dimensions with measuring instruments such as calipers and micrometers. The primary work is on factory production lines, where protective gear must be worn and measures against dust and noise are necessary.
Future Outlook
Demand for glass products remains stable, with steady demand continuing for processing into food containers, building materials, and more. While the introduction of automation equipment progresses, the role of skilled technicians handling fine manual high-precision processing is expected to remain.
