What is the difference between milling cutters for machining steel parts and aluminum alloys?

Tungsten steel means that the material used to make milling cutters is tungsten carbide. The aluminum milling cutter machining the object is aluminum alloy, which shouldn't be cutting steel parts, They are too easily destroyed.

It is recommended to use one of the following three types of tools for machining:

1. Uncoated ultrafine-grained carbide tools.

2. Carbide tools with non-aluminum coating (PVD) method, such as TiN, TiC, etc.

3. PCD Cutters. The chip space of the tool should be large. It is generally recommended to use 4 Flutes, and the rake and clearance angles should be large. If it is only a general face milling. In that case, you can use an indexable face milling cutter with a 45-degree main offset, and match it with a carbide insert which is specially processed for aluminum alloy, the results should be better.

Aluminum Alloy End Mill 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. Mild steel is mostly supplied through 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 mild 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-flute milling cutters without coating are used to process aluminum alloys. Secondly, due to the difference in processing conditions, 2Flute ball-end cutters or 4Flute flat-bottom cutters are likely to be used.

The processing of aluminum alloy is also related to the following factors:

Usually, The number of edge tungsten steel milling cutter for aluminum is 3 Flute, and the material is cemented carbide, which can reduce the chemical affinity between the endmill cutters and the aluminum alloy. High-speed steel milling cutters for high-speed steel aluminum are sharper and 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 the cutters

The steel parts are also divided into carbon steel and stainless steel. The material of the carbide tools used can vary greatly depending on the material, especially for stainless steel, You have to distinguish whether you are end milling or side milling. For end milling, you use a disk-shaped cutter processing cost is lower, side milling depends on how much your milling volume is. if the volume is small, you can use the carbide roughing milling cutter
