Our expertise and experience will be useful both to beginners - specialists in metalworking and to our customers. Every week we publish relevant materials about novelties in the field of metalworking, technologies, news, and achievements of our company on the market. In the blog, Lezometal company experts provide only practically proven information in an accessible and understandable language. It will be interesting!
Metalworking on CNC machines is one of the most modern methods of processing alloys. CNC machines allow specialists to produce a larger number of parts than manually at the same time. In addition, the accuracy of this method of processing metals and alloys is 1:1000, which practically eliminates the human factor.
What are the advantages of metalworking on CNC machines?
The advantages of metal processing on CNC machines include:
- High processing accuracy is guaranteed. We manufacture any number of parts in a short period of time, the accuracy of which is 1 to 1000.
- Exclusion of the influence of the human factor. The operator of CNC machines does not affect the quality of the production of parts, but only ensures the loading and unloading of parts from the machine, and manages its operation.
- Performing several operations on one machine. To save time and speed up the execution of the order, it is possible to perform several operations on the same machine. The operator does not need to load and unload the workpieces each time for a new processing step.
The Lezometal company has a new service! Now we not only manufacture parts for you, but we can also design any item you want from scratch and produce test samples if necessary. Interested? Read on!
What are design services (design solutions)?
Design solutions are the most modern way to create a visualization of your part with the possibility of its subsequent manufacture. We use 3D modeling for this. This method will allow you to see the future part and, if necessary, adjust its elements in time, without spending time and money on the production of a test sample.
Our designers develop and implement projects for CNC machining centers, particularly robotic automatic welding, and metal laser cutting installations, which significantly increase the speed of execution of large orders. In addition, with the help of 3D models, we describe and control objects during production. Therefore, after the completion of all work, we receive the most accurate details.
The mechanical processing of metals has significantly accelerated and made the processes of manufacturing metal products of higher quality. We have automated the production of parts and blanks and successfully implemented hundreds of orders in the shortest possible time and with high-quality manufactured products.
Our production is equipped with HAAS numerical software control. CNC metalworking has a number of significant advantages: it ensures high quality of turning, milling, and other operations. In our work, we use the latest MasterCam software, which helps us with programming and modeling parts.
Currently, four main tools and their varieties are used for processing steel surfaces:
- grinding disc.
Although steel is compared to iron, it is actually an alloy in which, in addition to iron itself, there are many other metals and substances in the form of impurities. As a result, steel has different types and markings, which we will talk about later.
So, by what features do we classify and mark steel? There are several such signs:
- by the degree of doping;
- by steel quality;
- by appointment;
- according to the method of deoxidation.
Laser metal cutting or laser cutting is a method of cutting and cutting metal using a powerful laser. Thanks to this processing method, the cut parts are extremely neat and with clear contours without errors. Also, laser cutting of metal allows you to produce parts of complex, unusual shapes, which are difficult to implement using other methods of metalworking.
The principle of operation is simple: cutting takes place thanks to the action of a powerful laser controlled by a computer. Under the influence of the laser beam, the area on which it is directed ignites and melts. In the process of work, there is no mechanical impact on the metal. Laser cutting is also safe for soft alloys and easily deformable metals.
What metals are suitable for laser cutting? The ideal option is metals with low thermal conductivity. There are several of them:
- Black (carbon) steel (thickness 0.2mm - 30mm);
- Stainless steel (thickness 0.2mm - 12mm);
- Brass (thickness 0.2mm - 12mm);
- Aluminum, aluminum alloys (thickness 0.2 mm - 20 mm);
- Copper, copper alloys (thickness 0.2 mm - 15 mm);
Metal processing in Lviv is our main specialization. Therefore, it is necessary to reveal this topic in more detail. What is metal processing? This is a process that consists in influencing metal or metal alloys with the help of manual labor or special equipment, in order to achieve certain forms, characteristics, dimensions, etc.
What are the main metal processing methods? There are four of them:
- Mechanical processing (cutting).
- Processing of metals under pressure.
All of them can be used both individually and in a complex and various combinations with each other. Let's look at each of them further.
Mechanical (milling) processing or cutting is a technology that is a mechanical effect on materials with the help of tools that, cutting, remove excess. As a result of this process, the metal acquires the required shape.
Processing on milling machines: a multifunctional method of metal processing - this is exactly what we will talk about next. Our specialists have more than 10 years of experience in milling work, so they are happy to share their insights with the readers of our blog. Let's start with the basics!
Types of milling works
Milling works on metal are classified by:
- by the fixing method of the processed workpiece;
- direction of rotation of the cutting element.
Milling according to the method of fixing the processed workpiece on the machine is divided into vertical, horizontal, and corner. According to the rotation of the milling cutter (cutting element), the milling of metal is opposite and parallel.
Counter milling involves the movement of the cutting edge towards the workpiece (on the tooth of the cutter). This is the fastest processing method. The accompanying milling process consists of the movement of the cutter from top to bottom (under the teeth of the cutter). This type of metalworking guarantees a clean cut.
Both of these methods can be combined, which will ensure a much smaller number of defective blanks. For example, large workpieces should be processed first by the opposite method, and later apply the parallel method.
The type of metal surface being processed also affects the method of metal milling. Different types of milling cutters are used for surfaces that differ in the type of fastening, construction, tooth shape, and other characteristics:
- terminal, used in the processing of large parts;
- end ones, which are used when necessary to drill a "well" or a window in the part, to make a groove on it;
- shaped - suitable for milling metal profiles;
- peripheral, the feature of which is a metal chip in the form of a comma sign that remains after milling.
