Cast iron tool and what milling cutter is used for cast iron

Cast iron is a common processing material in metal processing, so what milling cutter, cast iron machining tool, cast iron milling cutter and what are the characteristics of processing cast iron?　

First, the types and processing characteristics of cast iron cast iron according to its classification can be divided into; gray cast iron, white cast iron, malleable cast iron, ductile iron, vermicular graphite cast iron, alloy cast iron and so on. 　 　 　Gray cast iron is widely used in the automotive industry, and the automotive industry is a large demand for CNC tools, so processing plants often have gray cast iron processing needs. Second, the processing of ordinary cast iron with what milling cutter This paper refers to the common ordinary cast iron is gray cast iron, ductile iron and austenitic cast iron, gray cast iron processing performance is better, such as the use of alumina coated cemented carbide milling cutter, most of which can be competent for the cutting of gray cast iron. 　

Second, ductile iron because of its graphite content affects its processing performance, generally can be used as a whole cemented carbide bar economical coating alloy milling cutter. Ordinary cast iron processing tools, economical tungsten steel milling cutter can be competent. Secondly, cobalt-containing high-speed steel tools can be used.

Third, difficult to process cast iron with what cutting tools here for the time being only examples of cold and cold cast iron, its ductile iron processing tools, gray cast iron processing blades, cast iron processing special blades can be consulted Dongguan Dahai CNC. Cold Hard cast iron is a kind of anti-wear cast iron, it is in casting cast iron by speeding up the surface cooling of cast iron, so that its surface to obtain encyclopedia cast iron tissue, forming a high hardness, high wear resistance characteristics. Cold hard cast iron can be divided into ordinary cold hard cast iron, nickel chromium cold hard cast iron, high chromium white iron and chromium vanadium white iron and so on.

(1) cold hard cast iron processing characteristics of cold and cold cast iron hardness is very high, brittle is very large, unit cutting force is also very large, and its chip is crumbling shape, the tip of the knife because with the cutting contact is very short, resulting in cutting force and cutting heat concentrated near the cutting edge, easy to let the tool wear and damage. Cold and cold cast iron processing parts are mostly blank, processing allowance is large and uneven, which increases the difficulty of cast iron processing. Of course, the current cast iron processing tools, cast iron milling cutter and so on have a very good solution.

(2) cold hard cast iron processing tool selection processing cold hard cast iron better choice of high hardness, good wear resistance, with a certain strength of the tool material. It is generally coated with fine grains or ultra-fine grain YG cemented carbide or alumina ceramic tools.

(3) Processing of hard-cold cast iron milling cutter cutting dosage cemented carbide cutter; low speed large feed. V=9m/min or so, feed is generally based on the main deflection angle and back to eat the number of knives to choose. Cast iron roughing selection 0.5mm/r, cast iron finishing selection 0.1~0.4mm/r. Ceramic cutting tools; general selection of high-speed milling, coarse and semi-finishing cast iron V=50~80m/min, finishing V=80~120m/min. Cast iron processing tools, such as knife granules, Dongguan Dahai currently has Taiwan is Heyuan and other brands of knife grains, can be coarse, semi-fine and finishing. If you do not know what milling cutter for cast iron, processing cast iron milling cutter is of course the selection of YG cemented carbide tools.
