Free Cutting Steel also called Free Machining Steels are steels which are easy to machine. The machinability of the material is increased as the chips are broken in small pieces when machined thus avoiding their entanglement in the machinery. This enables automatic run of the equipment without human interaction. Free cutting steels with lead also allow for higher machining rates. As a thumb rule, free cutting steel normally costs 20% to 30% more than the standard steel. However this is made up by increased machining speeds, larger cuts, and longer tool life.
In turning, milling and drilling operations commonly known as machining operations, deformation/welding of the tool/work piece interface occurs rather than chip formation. During the machining operations surface finish is impaired, cutting temperature increased and tool life reduced significantly. A large ‘built-up edge’ is formed on the tool tip at very low sulfur contents. This requires frequent dressing or changing of tools, reduced productivity and higher costs.
GRADE SAE 1215
1215 free cutting steel is a kind of hot rolled cold drawn bar steel and steel wire which is suitable for automatic goods production in cutting process by adding sulfur element to the steel to make it free cutting.These steels can be machined at higher cutting speeds and greater depth of cut.
Due to the addition of the easy cutting elements in the steel, the cutting resistance of the steel decreases, and the characteristics of the easy cutting elements themselves and the compound formed by the lubrication of the cutting tool, easy to break chips, reduce wear and tear, thereby reducing the surface roughness of the workpiece, improve the tool life and production efficiency.
1215 because of the accuracy, good surface condition, easy to cut steel products can be directly used, such as spraying, sand, bending, drilling, but also according to the actual requirements of direct electroplating after fine drawing, eliminating a lot of machining time and save the cost of processing machinery configuration.
