Characteristic of special aluminum alloy milling cutter in CNC machining
Follow the progress of everyone's standard of living increasingly, people more and more love, there's something metallic simple sense, it also makes the aluminum products is more and more used in many professions. Aluminum industry in China generally is based on general machine tools, carved machine and CNC machining center is gone. About aluminum and aluminum alloy fine degree to select the machine. Because of special properties of aluminum, so no matter choose what kind of processing machine, cutter on aluminum produce professional speaking now in power, full of artifacts usually unsatisfactory gloss.
"Aluminum in the following characteristics: relatively high temperature alloy and steel, it is a soft metal, the hardness of HRC is not high, but it is patience. So phase of cutting tool, and relatively higher, if soft metal with high hardness of tungsten steel milling cutter for cutting, can make the blade broken, and cutting tool life is very short. It needs to be hardness is not high, and non-stick knife quality tools to end processing, knife can only such, ability progress speed of the machine, power ability improvement.
1, suitable for processing materials: aluminium and aluminium alloy, aluminium, die-casting aluminum, aluminum, copper alloy, magnesium alloy, zinc alloy. Aluminum alloy milling cutter
2, useful commodity around the burr is removed and beryllium front question and so on, has the excellent processing quality.
3, selects high rigid blade planning, bay shaking, precision parts appearance, glossiness is outstanding.
3, common blade slot planning, be helpful for production of iron, the aluminum table light burr.
4, negative rake Angle blade, can maximum limit bay tip collapse edge is because all the carbide cutting tools have very sharp cutting edges and slot type, its in aluminum finishing cutting force is small, and the chip space big bulk densities, such as chip removal smoothly strengths, so all the carbide nc cutter gradually replaced the traditional high speed steel tools. Aluminum alloy is a material with excellent machinability, the cutting force data unit for about a third of the steel, the melting point is 625 degrees. The low melting point means that no matter how high cutting speed, cutting zone temperature will not surpass 625 degrees. In the present excessive wear, has no effect on the strength of the cutting edge, before carbide blade can accept high temperature. Aluminum alloy milling cutter
Higher cutting speed on the needs of the power it will progress. Aluminum alloy of high speed machining, in fact, a common question is takes a lot of machine power, the general will cause metal removed under unit power consumption rate is low. Therefore, general need under the high speed machine tool can still supply as far as possible big output power in high speed machining aluminum alloy, because of the improvement of the cutting tool and make the required power decrease is very beneficial.
From the perspective of the concept of the cutting tool, the main cutting force influence on the resolution power needs to have sex. Drop unit data to remove the required amount of power for aluminum alloy milling use have obvious positive effect, specific table now yield higher power to every working procedure, and machine tool processing ability is stronger. Anterior horn besides resolution is cutting balloon, will also affect to the main cutting force. New blade planning through increasing the rake Angle, and blade how much the rest of the configuration matching each other together, cutting force can be cut as much as possible, using the new 790 blade CoroMill planning greatly decreased power needs.
