Cutting Of Billet
Steel production involves various stages. Metals are typically transported in the form of plates, sheets, bars or wire coils but
these configurations cannot be easily applied in all industrial applications. Thus, a cutting or trimming process is an essential
precursor to several metal forming processes, including forging, part forming, heading and form rolling. Shearing is one of the
main methods of preparing billets used in forging processes or rods used in part forming processes.
Shearing processes are advantageous in terms of reducing processing times and material loss.
The processing time associated with shearing is shorter than that associated with shearing is shorter than that associated with cutting a bar using a saw, blade or laser.
Material loss is also low in case of shearing. The shape of the cut edge in steel production after shearing is imperfect and in addition the surface roughness of the sheared end face is suboptimal.
Billets cut with a blade or laser possess find end surface characteristics. Torsion can be used to break ductile materials along the cross section. A few minutes are required to cut materials using torsion and the productivity of torsion cutting is low. It is impossible to cut materials at predetermined locations between the chucks.
Billet cutting machine is a kind of cold shearing machine which is used to cut the steel bar for the close die forging production line.

In the production of steel raw parts for bulk metal forming operations, billet shearing is the most applied and productive method.
The material lossless process is characterized by a good automation capacity, high production rates, short cycle times of 1 part per second or less and
high profitability in processing diameters up to 120 mm of steel material. In the procedure, two shear blades move past each other, so that a billet is
cut off a remaining bar. The bar is clamped between the bar holder and the stationary bar blade plus the bar holder. The billet blade moves past the bar
blade at a defined velocity and cuts the billet off the remaining bar section. The use of shearing machines has been established for the process of billet shearing in steel production. Special driving techniques have been handled in the procedure.
