Turning, milling and boring of parts up to 5 metres and 16,000 kg — from a single prototype to series production, with tolerances to ±0.01 mm.
CNC machining is computer-controlled cutting of metal: the machine follows a prepared program and removes material until the blank becomes the finished part. Kovine Gorsek has run CNC machines since the 1990s. Today 15 machines handle parts that most shops turn away because of size or complexity.
Turning of workpieces up to 1100 mm in diameter and 4000 mm long — shafts, flanges, hydro-turbine axles and other rotational parts, including combined turning and milling.
3-, 4- and 5-axis milling of parts up to 5000 × 2500 × 1600 mm. Simultaneous 5-axis machining covers complex geometry, including Pelton, Francis and Kaplan turbine runners.
Horizontal boring mills for heavy weldments and castings up to 16,000 kg. On selected machines the workpiece weight is not limited.
The shop specialises in large and difficult metal parts that exceed the capacity of a conventional machining centre.
Machine sizes are listed on the machinery page.
Milling large workpieces means 3- to 5-axis CNC milling of parts that will not fit a standard machining centre. We mill and bore up to 5000 × 2500 × 1600 mm and 16,000 kg, with no weight limit on selected machines. Typical parts are weldments, castings and housings for power generation, mining and shipbuilding.

Programmers prepare the job in Mastercam or Hypermill, choose the tools, and set the process for the right balance of cost and quality.
Turning, milling and boring on 15 CNC machines — from a prototype to a series, including parts up to 5 metres.
Every part is measured. An inspection report can be included, and the part is delivered in Slovenia and to 20 countries.

We mill and bore parts up to 5000 × 2500 × 1600 mm and 16,000 kg, and turn workpieces up to 1100 mm in diameter and 4000 mm long. On selected machines there is no weight limit.
Structural and tool steels, stainless steel, aluminium and aluminium alloys, copper, bronze, grey cast iron, and special alloys to your specification.
Tolerances to ±0.01 mm. Every part is inspected before delivery, and an inspection report can be supplied on request.
Both. One-off prototypes, repairs and spare parts, and repeating series production.
