Strunjaci

Strunjaci, or lathe operators, are skilled workers who shape metal and other materials by removing material on turning machines. The term is used in several South Slavic languages, where strunjac denotes a person who operates a lathe. Strunjaci work in metalworking industries such as automotive, machine building, toolmaking, and maintenance, and may also handle turning operations in plastics or composites.

The core duties of strunjaci include setting up lathes (manual or CNC), selecting and installing cutting tools, and determining appropriate speeds and feeds for a given material and operation. They perform turning tasks such as facing, external and internal turning, threading, boring, knurling, and drilling as part of a continuous sequence to achieve the required dimensions and surface finish. Strunjaci read technical drawings, verify tolerances with measurement instruments (calipers, micrometers, gauges), and document results. They monitor machine performance, perform routine maintenance, and troubleshoot issues such as tool wear or misalignment. Safety is a central concern, with attention to proper PPE, workholding, chip management, and machine guarding.

Equipment used includes manual lathes, CNC lathes, turret lathes, and related tooling like inserts, drills, and gauges. In modern shops, strunjaci often work with CAD/CAM data and collaborate with programmers and inspectors to integrate turning operations into broader manufacturing processes.

Training for strunjaci typically involves vocational education or apprenticeship programs, supplemented by on-the-job training. Prospects depend on industry demand for skilled machinists and the growing use of automated and CNC turning, which increasingly values versatility and precision.
