1. Importance of the regular engine lathe

The regular engine lathe is a machine tool which gives a workpiece the desired shape, dimensions and surface quality by chip removal. Creating a movement between tool and workpiece, it places the tool on the point from which the chip has to be removed. The chip removal is carried out mainly by single-edged, permanently acting tools and serves to manufacture rotationally symmetrical workpieces required for high-standard machines and plants.

By the regular engine lathe work can be carried out such as:

- Centring by centring drill or single-point boring tool
- Plane turning
- Surfacing
- Boring by twist drill or single-point boring tool
- Counterboring
- Reaming
- Recessing, cutting-out and parting-off
- Thread cutting by die, tap, etc., lathe tool (internal and external)
- Form turning
- Knurling and knurling straight-lined patterns

with the aim to manufacture workpieces true to size and of the required shape and surface quality.

Primary materials for turning are products of the rolling industry, forgings, pressed parts and castings.
