CNC technology in the automotive industry

 In news en

For many years now, the machining industry has been put under increasing pressure because of  the rapid transition of the automotive sector towards the hybrid and electric models.

At this inflection point, we can already see the challenge that has been posed to industries manufacturing and supplying parts for combustion engines, the use of which will be reduced drastically when it comes to the construction of the new electric motor models, which require a simpler mechanism.

Therefore, the race between manufacturers to reduce costs, increase quality and maintain the stability of the parts is becoming more intense. The machining of aluminum, acrylic glass or polymethyl methacrylate (PMMA) combined with CNC technology (Computerized Numerical Control) are some of the applications that will give the manufacturers an advantage over their competitors.


CNC technology involves performing tasks such as drilling under computer control and automation of tasks, allowing superior performance. It has great advantages over other conventional methods, such as increased productivity, quality and accuracy, in addition to the creation of new milling possibilities.


For example, the arrival of processes carried out with CNC milling machines or CNC lathes allow high precision work to be carried out, including machining on flat surfaces or holes by means of computer control in different materials, increasing the number of operations and giving way to a better adaptation of machining for the automotive sector.


Therefore, machining with CNC technology can be used to manufacture with high quantity and precision different parts, such as engine blocks, suspension components, exhaust parts, carburettor housings, bushings and valve seals, among others. Using CAD tools, in addition, the part designs can be quickly modified to achieve different versions of the product (size, finishings, etc.).


In short, CNC technology offers effective solutions for sectors that require a large volume of production such as the automobile. If you are interested in knowing more about this technology, see the article ‘What is CNC? ‘ here.

Differences between TIG welding and MIG welding in precision machining


Among the most well-known welding techniques nowadays are TIG (Tungsten Inert Gas) welding and MIG (Metal Inert Gas) welding, two types of arc welding processes. In order to have a better understanding of them, we are going to define their differences.
