Title: Garri Berstein: Innovator in Work Piece Straightening Technologies
Introduction
Garri Berstein is a notable inventor based in Erkelenz, Germany. He has made significant contributions to the field of engineering, particularly in the area of work piece straightening technologies. With a total of 17 patents to his name, Berstein has developed innovative methods that enhance the fatigue strength of work pieces during the straightening process.
Latest Patents
Among his latest patents is a method for straightening out of true work pieces, especially crankshafts. This innovative truing operation ensures that the fatigue strength achieved in previous strengthening operations is not compromised. By inducing locally bounded compressive residual stresses in a surface layer zone of the work piece through a hardening operation, Berstein's method effectively reduces the out of true deformation. The process is repeated until the deformation is completely eliminated. Another significant patent involves a method and apparatus for truing or straightening out of true work pieces, which maintains the characteristic fatigue strength of the work piece. This is achieved through a similar process of inducing compressive residual forces, allowing for precise adjustments to eliminate any out of true deformation.
Career Highlights
Garri Berstein has worked with prominent companies in the engineering sector, including Wilhelm Hegenscheidt Gesellschaft GmbH and W. Hegenscheidt Gesellschaft GmbH. His experience in these organizations has contributed to his expertise in developing advanced straightening technologies.
