Metal Spinning
Spinning is a method of forming rotationally symmetrical sheet metal parts. In spinning, sheet metal blanks or pre-forms are formed into rotationally symmetrical hollow shapes. The blank or pre-form is clamped in the machine and rotated by the main drive. The spinning roller makes contact with the outer face of the workpiece and using CNC control it forms the blank as required. The wall thickness remains more or less constant and the metal is generally formed cold although machines can be specially adapted for hot working if required.
Established in 1891, Leifeld has been a leading innovator in the field of metal forming technology and the result is today’s state-of-the-art Playback/ CNC spinning machines. Skill-recording controls backed by CNC with graphical editing and programming features allow traditional craftsman's skills to be captured and harnessed in an industrial manufacturing environment. As a consequence, metal spinning now ranks with deep drawing and press-working for the volume production of a host of industrial parts.
Our spinforming machines are used for processing pewter, copper, brass, aluminium, steel, high-grade steel, as well as high-temperature alloys and many others. Our extensive experience and expertise in this sector also gives us a practical understanding of the operational and cost benefits delivered by metal spinning. Contact Us About Metal Spinning

The latest Leifeld Playback spinning machines arrive on site ready-assembled on a bedplate for single-lift installation and hooking up to mains services. High installed powers and in-built rigidity guarantee accurate repeatable results, whether working in light or heavy gauges, soft or tough metals, whilst the modular design offers a choice of auxiliaries providing maximum flexibility and enabling complex parts to be made in a single hit. With over 5000 machines now in the field, the Leifeld metal spinning range has become the workhorse of the spinning industry. There's a Leifeld metal spinning machine for all applications from the smallest processing unit to custom-built spinning machines.
CNC Programming
Machine programming can be done either online in CNC mode or off-line using our Opus programming system. Opus allows easy administration of the NC programmes. Using a database, the operator can select up to 30 different criteria to search for programmes, alter, delete, print and archive settings. It provides a graphical representation of the complete operating programme.
Ancillary Operations
By selecting from a range of auxiliary attachments, a basic spinning machine can become a versatile spinning centre. Its easy to operate and capable of carrying out more than one operation in a single cycle. The range of ancillary operations provides flexibility and gives manufacturers the scope to diversify and adopt new techniques as the market demands. Ancillary Operations include:
- Planishing
- Profiling
- Curling

- Seaming
- Beading
- Cutting-off
