Job Description

The Machine Shop Lathe machinist is responsible to Operate and set up manual and/or CNC lathes to machine precision components per engineering drawings, GD&T, and quality standards; ensure safe operations, on‑time delivery, and first‑pass yield for customers.

• Interpret engineering drawings/3D models; determine process sequence, work holding, and cutting data (speed/feed, DOC).Set up, offset, and operate engine/toolroom lathes; verify zero references and tool offsets.
• Perform turning, facing, boring, threading (metric/imperial), parting, grooving, taper turning, and knurling to specification.
• Achieve required tolerances and surface finish; deburr and verify dimensions using precision measuring instruments.
• Conduct first‑article inspection and comply with in‑process checkpoints/control plans; update job travelers and production logs.
• Select, preset, and maintain cutting tools (carbide/HSS inserts), collets/chucks, centers, and steady/follow rests; manage tool wear.
• Execute preventive maintenance on machines (lubrication, alignment checks, coolant management); promptly escalate abnormalities.
• Coordinate with EDM/CNC Milling/Grinding cells for multi‑process jobs; ensure proper hand‑off and traceability.
• Adhere to 5S, Safety, LOTO, ESD (if applicable), IMS/QA procedures.
• Support Kaizen, TPM, and LSS initiatives; recommend parameter/tooling improvements to reduce cycle time, scrap, and rework.

• Strong lathe fundamentals: work holding, center height, tool geometry, insert selection/grades, coolant application.
• Proficient in GD&T interpretation; capable of holding tight tolerances (e.g., ±0.01 mm or per job requirement).
• Metrology proficiency: micrometers (OD/ID), bore gauges, telescopic gauges, dial indicators/test indicators, height gauges, surface roughness checker, and profile projector/vision system.
• Basic CNC lathe knowledge (G/M codes, offsets, canned cycles) and CAD/CAM literacy are advantages.
• Troubleshooting: chatter, tool wear/breakage, taper control, surface finish issues, thermal growth/compensation.
• Strong safety, quality, and documentation discipline
