CNC machining is a term that is widely used in manufacturing and industrial applications. But do you know what exactly the abbreviation CNC stands for? The term CNC refers to “Computer Numerical Control” used in manufacturing processes. Machine tools are typically used in conjunction with computerized controls to remove layers of material, resulting in the manufacture of an individually designed part.
To be precise, this process is ideal for a wide range of materials including metals, plastics, wood, foam, glass, etc. Since the CNC machines run in a highly automated environment, they can usually be found where high precision and high accuracy are the top priorities. One of the most salient features of a CNC machine is the use of perforated tape techniques to achieve greater efficiency in automated environments.
One of the most distinctive features of CNC machining is its automated walking platform. Automatic control systems can also be used on the machine tool to regulate all of the machine functions. The punched tape in CNC machines plays a crucial role so that the CNC machines can receive commands in digital form. It is noteworthy that CNC machines can also interpret additional data as a command of the speed or of individual functions.
What are the characteristics of a CNC machine?
Important features of CNC machining
It should be noted that CNC machines are usually equipped with automatic tool change holders and are controlled by a program. It can be seen from this that the workflow is much more effective. In all CNC machines, an electronic measuring system is used on each controlled axis. The measuring systems are usually used in CNC machines to determine the position of a slide on the guide way.
These systems also play a crucial role in aligning the spindle table and measuring the actual spindle speed. CNC controls are the main components of CNC machining. The new CNC controls have been developed for simple applications related to turning centers and grinding. The advanced numerical computer controls, on the other hand, enable more precise control of the various axes and thus faster interpolation of the positions. So let’s take a look at some of the key features of CNC machining.
Lubrication systems – Automated lubrication systems
It is important to note that a machine tool that is regularly serviced and lubricated will also work reliably over the long term. It is a well-established fact that insufficient lubrication of the bearings would lead to premature damage to the bearings. In addition, insufficient lubrication can also damage the running rails. In other words, if there was a lack of lubrication, the reliability of the machine would decrease.
Usually, CNC machine repair costs are quite expensive. Therefore, it makes sense to opt for such CNC machines that are equipped with a self-lubricating mechanism. It is also referred to as automated lubrication systems, in which each store of the device is connected to a central distributor. The lubricant distributor automatically ensures a programmable and pressurized oil supply to each bearing.
What are drilling heads used for in CNC lathe machining?
Boring heads are an indispensable part of CNC machines that are commonly used in the woodworking industry. It is known that the woodworking industry needs to mass-produce a design with various shapes and sizes. Hence, it is not practical to edit designs on an individual basis. Therefore, the CNC machines should be equipped with drill heads that help the woodworkers cut out intricate details with relative ease. The drill heads and units are also used in other industries in which fine craftsmanship is of the greatest relevance.
What are the advantages of automating the CNC machining process?
After debugging and verifying the test cutting process, the automation of the CNC machines can be used to save critical time while ensuring quality. The process can also be used as a template for subsequent machining of other similar parts. With the transitive properties of CNC machines, various work processes in industry can be rationalized.
What are the different spindles in CNC machining?
Important features of CNC machining
Both 3-axis and 5-axis CNC machines have an expanded range of options when it comes to spindles. The HSD and Perske spindles are already a big seller in the field of CNC machining. They are efficient and resilient and at the same time guarantee you the highest precision. In addition, vacuum pumps are an optional feature in CNC machines. Vacuum pumps give CNC machines power and stability.
Automated tool length adjusters
Automated tool length setting devices can make the 3-axis and 5-axis CNC machines more efficient. The length measuring systems are highly accurate. In addition, they consist of a single M-code that carries out the selection of the tool in an automated environment. In addition, the positioning of the tool in relation to the measuring position of the probe can be fine-tuned with the aid of automatic tool length adjusters. When the test has recognized the machine, the individually measured tool length is automatically saved in the tool correction table.
Fagor controllers are also an integral part of 3-axis and 5-axis CNC machines. Although most CNC machines are equipped with this functionality, other manufacturers do not preinstall it in their CNC machines. If your CNC machine does not have Fagor controls, it is best to purchase them from any third party.
Before starting the manufacturing process, it is essential to carry out preliminary tests
To be precise, the CNC machining environment is highly automated. This is the reason why one needs to pay due attention to safety and quality. In other words: The CNC-related machining processes must meet all operating and production criteria in a practical test. A test run before actually starting production would save you a lot of trouble.
As already mentioned, the functions are very demanding to use. This is also the reason why CNC machining is so advanced over the traditional methods of milling and CNC lathe machining center. Taking the characteristics into account helps to operate the machine with high precision and efficiency.
