The mechanics of the cupola furnace and the casting solidification process. 3. Forging and Hot/Cold Working Elements Of Workshop Technology By Hajra Choudhary Vol 1

1. Material: Choose free-machining bronze stock size slightly oversize for finish turns.
2. Rough turning: Remove bulk on lathe—use carbide insert, conservative speed, deep cut.
3. Heat stress relief if required (for hardened steel).
4. Finish turning: Final diameter with small depth and fine feed; measure with micrometer.
5. Boring/ID finish: Bore to size, ream/hone for concentricity and surface finish.
6. Chamfer and deburr; check tolerances with plug gauge and runout on V-block.
7. Surface treatment: Light polishing or plating if corrosion resistance required.
8. Final inspection & marking.
