Industry & Occupation
Classification
Summary
A skilled craft job that removes burrs and excess parts from metal parts formed by casting or forging using chisels, files, hammers, etc., to achieve high-precision shapes and surface finishes.
Description
Chisel grinders remove burrs and excess metal remaining on metal parts after casting or forging using hand tools such as chisels, hammers, scrapers, and files, ensuring shapes, dimensions, and surface quality match the design drawings. They secure parts with vises or dedicated jigs and proceed with grinding while measuring dimensions visually or with calipers and micrometers. The work is primarily manual, requiring excellent manual dexterity and concentration. They play an important role in factory production lines or small-batch, high-variety production sites as a pre-process for precision finishing and inspection. The work environment involves metal shavings, noise, and oil stains, requiring safety measures and protective gear.
Future Outlook
Even as factories advance in automation and robotization, high skills are required for fine finishing and small-batch, high-variety production, and demand for manual work is expected to continue to a certain extent.
