Stainless steel material automatic lathe cutting steel (free cutting steel) by adding a certain amount of one or more of sulfur, phosphorus, lead, calcium, selenium, tellurium and other cutting elements in the steel to improve its machinability of steel . Also known as the automatic machining of steel, referred to as auto steel. Such steel can be higher cutting speed and a larger depth of cut for cutting. Added to the steel in the cutting element, the cutting resistance of steel decreases, also act as lubrication of the cutting tool itself, the characteristics of the cutting element and the compound formed, the frangible debris, reducing wear and tear, thereby reducing the surface of the workpiece roughness and improve the tool life and productivity. Cutting steel new standard GBl91-75 main purposes: cutting steel is mainly used to produce smaller force while the size and finish demanding instrumentation, watch parts, automobiles, machine tools and other various machines used for dimensional accuracy and finish demanding, while the relatively low mechanical performance requirements of standard parts, such as gears, shafts, bolts, valves, bushings, pins, fittings, spring seat and machine screw, plastic mold, surgical and Dental procedures appliances. Follows ⒈ automatic lathe processing, metal stamping parts processing; ⒉ electronics industry, light fiber connectors, optical drives, scanners, medical equipment; three household appliances, instrumentation industry; ⒋ office equipment (computers, photocopiers, cameras, fax etc.); ⒌ watch components, glasses; ⒍ electronic terminal pins, timers, carburetor; ⒎ decorations, lights jewelry, automobiles, motorcycles, chain; ⒏ sweep with a clean car, toys; ⒐ pens, handbags accessories, belt buckle, fishing gear and other; ⒑ studs, screws, nuts, fittings, spring seat and so on. Features: ⒈ processing performance: The product has a cutting fluid, excellent material, processing stability, good microstructure, chemical stability, small deviations, steel purity net, low inclusion content, easy to damage the knives and other characteristics; very easy in lathe cutting tool life and productivity were increased 40%; good ⒉ plating performance: Cutting is easy; to drill deep, deep groove milling etc; processing efficiency can be significantly higher than normal steel; good plating performance, can substitute copper, greatly reducing product costs; ⒊ clean and good: The car machined workpiece surface finish; ⒋ environmental protection: SGS environmental certification in line with EU standards, and certified by the Swiss environment. Products can be exported machinery and equipment: woodworking machinery, ceramic machinery, paper machinery, glass machinery, food machinery, construction machinery, plastics machinery, textile machinery, jacks, hydraulic machines; electrical products components: the motor shaft, fan shaft, machine shaft and so on; furniture : especially the export of metal furniture, such as coffee table, chairs, outdoor furniture; metal utensils: garden tools, grill grid, screwdriver, anti-theft lock;
