Precise aluminium machining plays an important role in the production of industrial components, where both strength and accuracy of workmanship are important. Thanks to its properties, aluminium is used in many sectors, from aviation and automotive to electronics and medical equipment. However, in order to exploit its full potential, knowledge of the appropriate techniques and technologies is essential. CNC machining of aluminium at RADMOT is a guarantee of quality, resulting from a combination of experience, advanced machinery and a comprehensive approach to projects.
Aluminium is characterised by low density, high thermal and electrical conductivity, and natural corrosion resistance. At the same time, it is strong enough to replace heavier metals, which reduces the weight of structures. The properties of aluminium make it suitable for use in precision machining, especially in the production of lightweight and durable components.
Aluminium machining is used in the aerospace, automotive, consumer electronics, medical and defence industries. Thanks to its material parameters and susceptibility to anodising, aluminium allows for the creation of durable and aesthetic parts. RADMOT carries out comprehensive orders for all these sectors - discover our modern CNC machine park.
What aluminium is used in industry? Alloy 6061 is a versatile material - easy to machine, corrosion resistant and suitable for welding. 7075 is distinguished by its strength - used in the aerospace industry. 2024 offers good fatigue strength but lower corrosion resistance, which requires additional surface treatment. CNC milling of these alloys requires an individual technological approach. Professional CNC milling – check out our services in the field of aluminium machining.
The choice of alloy should be based on the specific application of the component – whether it is resistance to weather conditions, mechanical loads or weight that matters. RADMOT helps to select the right alloy by analysing the project requirements and optimising the cost in relation to durability.
In order to achieve high quality and repeatability of aluminium parts, it is necessary to precisely set the cutting parameters: rotational speed, feed rate and cutting depth. Aluminium allows for high speeds, but with control over the process temperature and avoidance of vibrations. This is important for both turning aluminium and milling.
For turning or milling aluminium, tools with carbide blades are used. These tools have a special geometry, which ensures efficient production and high-quality machined surfaces. This prevents material adhesion and increases tool life, which has a direct impact on the efficiency of CNC aluminium machining.
Effective cooling with mineral coolant and non-emulsifying oil for automatic machines prevents the machined material from overheating and reduces the risk of deformation. The associated lubrication improves surface quality and reduces tool wear. RADMOT uses modern cooling systems adapted to the requirements of large-scale production.
Aluminium tends to stick to tool blades, which can damage the surface quality. The solution is to use tools with appropriate coatings, control the temperature and remove chips.
When machining thin-walled aluminium parts, deformation can easily occur - the material bends under the influence of cutting forces. To prevent this, appropriate strategies are used, including shallower cutting depths, lower feed rates and multiple finishing passes. It is also crucial to secure the workpiece firmly and plan the sequence of operations so as not to weaken the structure too early.
In the production of aluminium parts, measurements carried out in accordance with ISO standards are crucial. RADMOT has one of the largest measuring equipment facilities in Poland, which allows for tolerances of several micrometres to be achieved.
Anodising aluminium parts increases their corrosion resistance and improves their aesthetic qualities. Electropolishing smoothes the surface, while glass bead blasting removes minor imperfections. Anodising of aluminium parts – durability and aesthetics from RADMOT is a guarantee of satisfaction. We are one of the few companies in Poland to offer anodising in our own plant.
Properly selected and executed finishing extends the service life of aluminium components, increases wear resistance and ensures consistent visual quality. This is particularly important in industries where aesthetics go hand in hand with functionality, e.g. in the consumer electronics sector. Aluminium processing – precision and lightness of construction from RADMOT is the choice for companies that seek the best quality solutions.
The high quality of aluminium components results from a combination of: the right choice of alloy, advanced CNC machining parameters, experienced staff and quality control. Precision machining is also a matter of process repeatability in large-scale production.
RADMOT's modern machine park, comprising over 80 CNC machines, allows us to carry out the most demanding projects.
