The Cutting And Machining Characteristics Of Aluminum


If the object is limited to aluminum, machining can be viewed from a different perspective than steel. These properties open up new uses for aluminium, where different cnc machining conditions and methods can be applied than steel. There are many types of machining, but here we will focus on cutting. Even with Aluminum, machining such as cutting, grinding, and polishing is actually used. However, cutting is the most widely used.

The latest developments in china cnc machining technology are impressive. For cnc machine, such as ultra-high-speed cnc machines with spindle speeds of tens of thousands of revolutions and machining centers that can perform various types of cuts with automatic tools and changers. As for tools, carbide tools are already common, and natural single crystal diamond tools are also used on an industrial scale. In addition, there are a large number of ultra-precision cut products that take full advantage of these technologies. The current situation is that as these technological developments are closely related to the cutting characteristics of aluminum, cutting technology is becoming more and more mature.

High Machining And Cutting Speed

Most aluminum is softer than steel, so it can be cut at high speed. There are also many cutting manufacturers that mass-produce at speeds of 1,200 m / min or higher. Generally speaking, alminium can be cut at a speed four to five times faster than that of steel. The productivity is high and the cutting cost is low.

It Can Be Continuously Cut For Long Time

For the same reason, aluminum can be cut for a long time. The tools are not worn out too much. In fact, some cutting manufacturers say that they did not change tools for a week at full operation 24 hours a day. Of course, not all aluminum can do this for him like this. Damage to the equipment is a problem for some metal fittings (very high Si metal fittings). However, compared to steel, aluminum is much easier to cut continuously.

The Wide Range Of Suitable Cutting Conditions

Not only the cutting speed but also the cutting and feeding can be selected in a wide range. In general, aluminum is soft and causes less damage to the equipment. Therefore, it is relatively easy to perform from light cutting to heavy cutting.

Less Energy Is Required For Cnc Machining

Since the resistance of aluminum to deformation is smaller than that of steel, less energy is required for cnc machining or cutting.

Good Cnc Machining Or Cutting Accuracy

It is relatively easy to obtain a machining accuracy of about 10 μm even with ordinary cutting. In ultra-fine cutting, a surface roughness of 0.01 μm and a roundness of 3 μm are obtained. With steel, it’s difficult for him to achieve a level of accuracy.

There Are Few Restrictions On Mechanical Rigidity

With steel, there is a great deal of resistance to deformation, so mechanical rigidity may become an issue in achieving precision. However, there are few such problems with Alminium.

High Flexibility With Respect To Machining Parts

As a result of the above characteristics, cutting of alminium can be performed with one piece or hundreds of thousands of pieces / month. Of course, it is the same with steel, but for that purpose, a large number of cutting machines are required.

Cnc Machining Aluminum

The Aluminum Alloy Material Of Cnc Machining


Aluminum alloys can be easily machined and have a low raw material cost, making them often the most economical choice for prototyping and machined metal parts.Its density is low, around a third of that of steel, and it has an excellent strength/weight ratio, making it a very interesting structural material. It is also a non-magnetic material.Aluminum alloys has natural protection against corrosion. In addition, it can be anodized if greater control of the external oxide layer and an aesthetic finish are desired.It has high thermal conductivity and high electrical conductivity (although anodizing is not electrically conductive).Aluminum alloy is also very suitable for cold environments. It has the advantage over steel in that its tensile strength increases with decreasing temperature, while retaining its hardness. Steel, on the other hand, becomes brittle at low temperatures.

Aluminum 6061 Machining


Aluminum 6061 Machining
Aluminum 6061 is the most used aluminum alloy for machining and the most versatile and economical. It has good resistance to corrosion and welds well, although it must be taken into account that aluminum loses almost 30% of the breaking load in the welded area. It is an alloy that is halfway between the mechanical characteristics of 6063 and the alloys of the Aluminum-Copper (2000 Series) and Aluminum-Zinc (7000 Series) families. The quality of the anodizing is very good.They are used in:Aviation, automotive components, bicycle components, food containers, etc.

Aluminum 6082 Machining
