is a metalworking process by which a sheet metal disc is rotated at high speed and formed into an axially symmetric blank part. A metal spinning tools shapes the workpiece, applying controlled force to cause it to flow over the stencil which is also attached to rotating mandrel of a lathe.
Spin forming done by hand is an effective production method for prototypes as well as for small and medium quantity production runs. The advantages of metal spinning include the ability to create objects seamlessly by using a single piece of material. The workpiece geometry can be altered quickly, at less cost than other metal forming techniques. Tooling and production costs are also comparatively low.
from which a disc with precisely set diameter is cut. Metal spinning can be performed on any ductile metal, such as steel, brass, copper, aluminum, titan alloys, zink alloys and precious metals like silver, gold and platinium.
is a specialized machine with construction similar to the conventional lathe. A formed block is mounted in the drive section. A pre-sized metal disk is then clamped against the block by a pressure pad, which is attached to the tailstock. The block and workpiece are then rotated together at high speeds. A localized force is then applied to the workpiece to cause it to flow over the block. The force is usually applied via various levered tools called the spoons.
Hand metal turning is a very physically demanding profession requiring many years of practice to master the skills of metal forming. The difficulty in mastering the art of spinning lies in the fact that each type of metal requires specific skills in the time of its formation. It happens that the spinner is well trained in the shaping of steel and aluminium but he is unable to work with brass or silver as it behaves differently during processing.
The history of the plant dates back to 1946. Edward Sucharski, a very experienced spinner, who had mastered the art of metal turning at the Borkowski Brothers Factory before WW2, opened his own business in the destroyed Warsaw city on Solna 3 street. From its beginning, the plant was specialized in producing equipment for barber shops such as razor containers, shaving brushes, beard and mustache brushes and perfume atomizers, formed mostly out from the brass and copper. In the twentieth century the company had to move twice, in 1954 to Wolska St. and in 1968 to Skierniewicka St no.12.
Marek Rosiak, son in law of the owner of the plant demonstrated extraordinary talent in the difficult craft of metal spinning. After he had aquaried the title of master of art, in 1978 a company called "Metal-workers. Edward Sucharski & Marek Rosiak" formed. Under this banner the plant existed till 1984, when Mr. Edward had died. In the following years, the company changed its name to Drykomet, the company extended slightly the range of manufactured products adapting to market needs. The production of lightning components had started, and various other products such as metal balls, goblets, sugar bowls, and patens. In 2005 the company had to move once again for 5 years to Obozowa St. no.16. just to finally change the adress to Wojnicka 2 St. where it operates till this day under the name Drykier Rosiak.
