Milling aluminum alloy has the following major features;

1, aluminum alloy hardness is low
Compared to titanium alloys and other hardened steels, the hardness of aluminum alloys is lower, of course, heat treatment, or the hardness of die-cast aluminum alloys is also high. HRC hardness of ordinary aluminum plate is generally below HRC40 degrees. Therefore, when machining aluminum alloys, the load on the tool is small. Because of the better thermal conductivity of the aluminum alloy, the milling temperature of the milling aluminum alloy is lower and the milling speed can be increased.
2, aluminum alloy plastic low
Aluminum alloys have low plasticity and low melting points. The problem of sticking knife is serious when processing aluminum alloy, the chip removal performance is poor, and the surface roughness is also relatively high. In fact, the processing of aluminum alloys is mainly a result of poor adhesion and roughness. As long as solving the problem of sticking knife and processing surface quality, the problem of aluminum alloy machining is solved.
3, the tool is easy to wear
Because of the unsuitable tool materials, when the aluminum alloy is processed, the wear of the tool is often accelerated due to problems such as sticking knife and chip removal.
Our ideal standard drill should have the following characteristics:

1. Cutting resistance is reduced further than that of group drilling;
2, suitable for drilling a variety of commonly used materials such as: carbon steel, stainless steel, cast iron, aluminum alloy … …;
3, not only suitable for drilling thin plates, but also for drilling deep holes;
4, especially suitable for use on hand drills;
5, suitable for large-scale industrial production.
Sintered carbide tools

The carbonized cutting tool is a powder metallurgy product. The main component of the tungsten carbide cutting tool is 50%~90% tungsten, and titanium, molybdenum, niobium, etc. are used as the binding agent for the cobalt powder, which is then heated and sintered. Carbonized cutters are harder than any other material, and they are three times harder than high carbon steels. They are suitable for cutting hard metals or stone materials. Because they are hard and brittle, they can only be made into sheets and then welded to be more flexible. On the tool shank, when such a blade is dulled or cracked, another blade or a new blade can be replaced. This enough tool is called a discarded turning tool.
