What is the process of CNC plastic machining parts?
The modern industry is able to produce extremely complex shapes and materials with excellent properties from metals. CNC plastic machining is a process that allows for their dynamic deformation without affecting the integrity of the materials. Plasticity is nothing more than the ability of metals or their alloys to deform. As a result of such treatments, many useful products can be obtained.
These are, among others: sections, bars and pipes, forgings, sheets and wires. These are not all possibilities. There are more advanced methods for obtaining even more complex components used in various industries. What processes help in obtaining the above products or semi-finished products?
Machined plastic components deformation processes
It is possible to change the physical and chemical properties of the product due to plastic working. This will come in handy in various industries. Similar effects can also be seen in the surface and structure properties.
What are the mechanisms that facilitate obtaining CNC machining plastic parts with the desired properties? In the process of such plastic working, deformation mechanisms such as forging, drawing, pressing and even rolling can be implemented.
Forging is a hot or cold process. It consists in industrial physical action on a given material by means of impacts and or pressure. This mechanism is mainly used in production on an industrial scale.
Drawing is used in cold or hot forming
The mechanism is based on the systematic stretching of a given material until the desired effects are obtained. The entire process should take place without the side effect in the form of unnecessary splinters or chips.
Bending of metal or its derivatives should be performed after it is heated or cold. As a result, it will be possible to create a change in the shape of the material without deforming its other dimensions.
CNC machining has revolutionized the manufacturing industry. All because it allows you to reduce production costs, it is an economical and effective method. So let’s find out what it is and what other advantages it has. It will all be included in this text.
Machining on CNC presses - what is it and how does it proceed?
It’s worth starting by deciphering the mysterious abbreviation CNC Computerized Numercial Control and translates as Computer Numerical Control. Therefore, this abbreviation applies to numerically controlled machines.
It also shows that the machining process is carried out using a computer using modern software. Machining on CNC presses, such as, for example, edge, hydraulic or servo-electric presses is otherwise known as metal forming.
Modern technology used in CNC machines enables the creation of complex shapes and details. The whole process usually takes 3 steps. It begins with computer design, then it is time to process the design, and finally it is completed, i.e.
It is important to remember about such elements as: the type of material to be processed, the technical capabilities of the machine tool, the available tools and the correct selection of parameters at an early stage – of programming the machine. After the device remembers these details, the production of the series will run more efficiently and without unnecessary interruptions.
In each case of plastic working of metals, the size and shape of a given element are permanently changed by exerting pressure on it. During its duration, the structure of the object also changes, and thus its mechanical properties (it has greater durability and strength.)
4 advantages of machining on CNC presses
- Digital control
The days have come when one machine supervises the work of another. In addition, it communicates with the operator via the interface and does not require its constant supervision. In addition to reducing the people needed to take care of production, it can become fully automatic and offer new solutions. Digital control is therefore a significant advantage of machining on CNC presses.
- Precision of execution
On the plus side of this method, the precision with which the process runs should be added. This method enables very accurate and even perfect mapping of elements. A given series can therefore be created without losses or errors, which minimize costs and help to gain a competitive advantage.
The speed of production also allows you to achieve the above-mentioned effects. Automating the process greatly accelerates it and significantly improves it.
4. Save time and resources
Currently, cnc machining plastic parts has become so popular and appreciated that it is used not only for mass production, but also for unit production. This happened, among others, because the CNC machines work efficiently, the edges do not require further processing and the materials are optimally used. As a result, the production time is shortened and the entire process is carried out without wasting material.
Although this modern technology is not cheap, it is gaining more and more customers and is used on an increasing scale. This is because its use has many advantages and pays for itself quickly.
cnc machining plastic parts is one of the most frequently used methods in metalworking. A characteristic feature of this method is a complete change in the shape of the workpiece. Its dimensions and structure are also changing. The basic activities in this technique are sheet bending and cutting. What is metal forming, what are the types? You will find out in the article below.
Metal forming - what is it?
When you start working with metalworking, you should first expand your knowledge in this area. This method uses the ability of metals to permanently deform. The cast ingots can be processed in any chosen way, incl. on:
Carrying out plastic working depends on the nature of the work that has taken place. It also leads to the production of various metal products. Qualified specialists are responsible for this, which is why such treatment is mainly used in industrial plants and production lines. Plastic processing does not require as many machines as in the case of machining.
For those interested, it is a great convenience that they are more and more willing to use in their daily work. The commenced process can be carried out cold or warm. The first option is at a temperature slightly lower than the recrystallization temperature, and the second at a higher temperature. Currently, the plastic working of metals is very widely used, among others in metallurgy and press, but also in industry.
Metal forming - types
Metal forming is performed by such activities as: solid shaping, sheet metal forming, electrodynamic forming, rolling, burnishing, explosive joining or bending.
More importantly, treatment in this variant can be carried out in three specific temperature ranges.
- Cold working of metal
Cold working is characterized by high forces and remarkable accuracy of operation.
- Hot plastic working of metals
Heat treatment is related to medium forces and accuracy.
- Hot forming of metals
Hot working, on the other hand, shows little force and low accuracy. Decisions in this matter are taken by experienced specialists, which is why plastic working is used in large workplaces.
Various machines and devices play an important role in plastic working. It is enough to mention, for example, coilers, compactors, guillotines, benders, presses, and laser cutters, rolling mills, drawing machines, and grooving and marking machines. The nature of the order is of great importance when selecting the machine.
