What is the difference between milling cutters for machining steel parts and aluminum alloys? Tungsten steel refers to the material of the milling cutter as tungsten steel, and the aluminum alloy milling cutter is the processing object of aluminum alloy. Steel parts are not usable, they are too easy to damage. It is recommended to use one of the following three types of tools for machining tools: uncoated ultrafine-grained carbide tools, carbide tools with non-aluminum coating (PVD) method, such as TiN, TiC, etc., with diamond tools. The chip space of the tool should be large. It is generally recommended to use 4 blades, and the rake and clearance angles should be large. If it is only a general face milling, you can use an indexable face milling cutter with a 45-degree entering angle and a blade specially processed for aluminum alloy, and the results should be better.
Aluminum alloy milling cutter, ultra-fine grain cemented carbide matrix, 40° helix angle, 2 or 3 edges, unique sharp cutting edge design makes the cutting process more brisk and smooth, improving the processing efficiency and the surface quality of the workpiece. Suitable for milling aluminum alloy and other non-ferrous metals. Ordinary steel is mostly supplied in the form of strips, profiles, and wires. Ordinary steel is a basic material that has been used earlier and used in large quantities in the industry and is widely used in various sectors of the national economy such as building structures, bridge components, and hull structures.
Compared with ordinary steel, aluminum alloy has the disadvantages of lower elastic modulus, poor weldability, and high cost, but aluminum alloy has the advantages of lightweight, good corrosion resistance, cold resistance, good durability, and beautiful appearance. To objectively evaluate the performance of aluminum, it is not difficult to see that despite its shortcomings, aluminum is still an ideal building material in general. As far as its development trend is concerned, it has certain application prospects in many engineering fields.
Generally, 3-blade aluminum milling cutters are used to process aluminum alloys. Secondly, due to the difference in processing conditions, 2-blade ball-end cutters or 4-blade flat-bottom cutters are likely to be used. The processing of aluminum alloy is also related to the following factors: the number of edges of the tungsten steel milling cutter for aluminum is generally 3 edges, and the material is generally cemented carbide, which can reduce the chemical affinity between the tool and the aluminum alloy. High-speed steel milling cutters for high-speed steel aluminum are sharper, and they can also process aluminum alloys well. Generally, high-speed and large-feed milling can be selected for processing ordinary aluminum alloy. Secondly, choose a larger rake angle as much as possible to increase the chip space and reduce the phenomenon of sticking knife;
The steel parts are also divided into ordinary carbon steel and stainless steel, and the materials are different, the materials of the tools used will be very different, especially for stainless steel, and you also need to distinguish whether you are end milling or side milling. If you use end milling, use a disc cutter. The cost of disk processing is lower. If you use side milling, it depends on how much your mill. If you have less, you can use a corrugated milling cutter.
