Cutting steel is added to elemental sulfur in the steel, it has easy cutting, in order to produce goods suitable for machining with automatic hot-rolled and cold-drawn steel bars. Such steel can be larger with a higher cutting speed and cutting depth of the cutting. Added in the steel cutting element, the cutting resistance of steel decreases, also act as the lubricating properties of the cutting tool cutting element itself, and the compound formed by the frangible debris, reducing wear and tear, thereby reducing the surface of the workpiece roughness improves tool life and productivity. With the continuous development of mechanical cutting to automated, high-speed and precision of the direction of the cutting of the material put forward higher requirements, so there better machinability lead a sulfur compound cutting steel, also known as super-easy cutting steel. After various lead a sulfur binary and multiple composite cutting steel have come out.
Delivery status bar steel factory direct delivery of the black rod, also called hot-rolled steel.
Cutting steel cold-drawn light bar: hardness up to 160 ~ 190HB, eliminating the need for heat treatment costs can be directly processed.
Polished bar: Surface roughness precision of plus or minus 0.05
Advantages
Cutting steel sulfur content, good cutting performance, high plasticity, higher strength.
Cutting steel products have the following advantages:
a shape specifications diversity: different shapes by designing the mold, cold pull in different cross-sectional shapes, different sizes of tolerance cutting steel. Angle can be straight or rounded corners.
b High accuracy: Use high-quality carbide tooling to ensure accurate tolerance, unity.
. c smooth surface: advanced cold extrusion process makes cutting steel product surface smooth and bright.
. e material substantial savings: cold drawing cold extrusion process is the raw material to achieve the desired shape deformation, specifications and tolerances, very little loss of raw materials, the relative use of traditional lathe machining cutting the consumption of materials, cutting steel savings materials and time is very impressive, especially when a large amount of material, material cost savings is more significant.
. f save processing time and processing machinery: The precision, the surface in good condition, free cutting steel product can be used directly, such as spraying, sanding, bending, drilling, in accordance with the actual requirements of finely drawn after direct plating, replacing a lot of machining time and cost-saving configuration processing machinery. Cutting steel products are widely used:
Mainly used for automatic cutting machining fasteners and standard parts, such as stud bolts, screws, nuts, fittings, spring seat and so on.
. a mechanical equipment: woodworking machinery, ceramic machinery, paper machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jacks, hydraulic machines;
. b electrical products components: the motor shaft, fan shaft, sewing machine shaft;
. c furniture: especially the export of metal furniture, such as coffee table, chairs, outdoor furniture;
. d metal utensils: garden tools, grill grid, screwdriver, anti-theft locks, etc.;
. e hardware parts: such as rails, machine keys, nuts, screws, nails, nail hexagonal, octagonal nails and other pieces of various specifications;
f. automobile, motorcycle spare parts.
