Bed Frame Fabrication for Heavy Duty Machine Tools or Unique of High Strenght Materials Quend 700

The purpose of the present work is to present new manufacturing technologies process of bed frame elements, especially those with a circular or conical section, made of high strength materials, new on the market. The research based on three methods to make this bed frame elements: cold deformation method, hot deformation method and cold deformation method after soft annealing. Experimental research is focused on how the steel behaves at high temperatures, in identifying an adequate improvement treatment for parts after soft annealing, to increase the mechanical properties of this and preparation of the welding procedure specification.
