Factory direct high-speed hacksaw piece HSS - M42250--450 thickness of the outer diameter of 1.0--3.5 not cut ..

The company is a leading China saw the development of specialized metal circular saw blades manufacturers, the company since its establishment at home and abroad continue to introduce advanced management by the study, development and production of high-speed steel circular saw blades saws based products, the The company produces a variety of blade cutter, three-blade cutter, high speed hacksaw, circular saw blades, white blades, and custom non-standard cutting tool. For a long time, we are actively strengthen exchanges and cooperation with foreign counterparts, to ensure the production of sawn products market demand and supply, the full catch different levels of customer demand. Faced with the evolving market demand, we will be strict product quality management, first-class brand quality, customer service satisfaction for the purpose, and constantly develop innovative, proactive, high-quality products and services returns new and old customers and the community to my company's support and love. The company from the China Hardware Yongkang a 25-minute ride from Jinliwen high-speed 20-minute ride, 5 minutes from the Wing-Taizhou-Wenzhou Expressway, convenient transportation, welcome to visit the plant, guidance. High-speed steel cutting blade is a metal containing large amounts of carbon (C), the blade tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements, and after heat treatment has a high fever hardness. Since the high-speed steel cutting temperatures up to at least 600 ℃, hardness no noticeable decrease of up to 60 meters per minute with the manufacturing of the blade cutting, high speed hacksaw piece, hence its name. Cutter blade outer diameter is usually 30-200MM, 250MM much more than the outer diameter pipe cutting blade called, materials are high-speed steel Note: Depending on the processing of different materials and pipe thickness size, gear type, different numbers of teeth, please select the correct teeth. High-speed hacksaw film also should note the following: First, the line speed line speed metal working process is very important as an indicator, the linear velocity of the tool life has a crucial determinant. General metal processing manual has a processing speed of some of the data lines can be used as a reference. In the sawing industry, problems most often encountered cutting stainless steel, stainless steel should be used in the processing of low speed, such as material, line speed 201 and 202 should not be higher than 30 m / min. Saw line speed is calculated as follows: linear velocity = blade diameter * 3.14 * RPM (machine spindle speed) Second, the off time depending on the work material, the amount of feed per tooth blade generally in the 0.02 ~ 0.05mm . This is an empirical value, if large enough power saw, and a chip conveyor, infeed amount can be larger, on the contrary, it is less. General carbon steel material uses 0.04mm. To measure a reasonable cut off time of a job, we need to prepare a stopwatch, test time is jagged sawtooth contact away from the workpiece surface to the range. Reasonable time off can be calculated as follows: for the amount of feed per teeth = RPM * * the amount of feed per tooth / 60 reasonable time off (round piece) = workpiece diameter / sec feed rate give an example: client with RPM = 60, cutting a pipe diameter of 50, saw teeth 240 per tooth feed rate = 60 * 240 * 0.04 / 60 = 9.6mm / sec reasonable cut off time = 50 / 9.6 = 5.2 seconds (this is a reasonable cut time does not include the head of the air travel) Third, pay attention when cutting the pipe other, try to make progress knife blade from the corner pipe, saw blade feed from the surface and from the corner motivated knife, blade life can vary to 3 times. HSS piece does not heat, it is best to take the use of cooling measures, the effect of using the emulsion concentration of 5% better, some technology we can not use water-cooled, can not use the oil, then the use of air coolers, but the chiller The effect is certainly not as good as emulsion. Cutting thick-walled tubes, solid rods, when stainless steel is best to install a saw wire brush, wire brush installation cost is not high, but the effect is very good.
