CNC machining, called “computer numerical control”, is a recognized and widely used machining technique in all high-tech industrial sectors. What are the advantages of this industrial production technology?
Speed, reliability, precision and robustness, why is CNC machining a cutting-edge technology?
CNC cutting and milling are processes for manufacturing parts by removing material. These production technologies allow high levels of precision and repeatability of operations. Machines can be programmed to operate reliably 24/7 if required. CNC milling is an ideal solution for producing parts (simple or complex) on demand.
CNC machining offers great production flexibility, making it possible to produce single parts (prototyping), in medium series or large series. The manufacturing time of a part can vary according to the quantity, the size, or the expected complexity.
CNC technology also makes it possible to work with a large number of materials while maintaining their mechanical properties. More than 50 industrial-grade metals, alloys, and plastics can be machined by CNC milling and turning.
CNC machining: how to control costs?
To obtain the most cost-effective CNC machined parts, it is recommended to produce large series. Thus, the unit price gradually decreases until it stabilizes. The cost will also vary depending on the method used (3 or 5-axis machining). 3-axis CNC milling is generally the cheapest method for manufacturing uncomplicated parts with high tolerances.
CNC turning on a lathe is also a very competitive process when cylindrical parts such as threaded rods and shaft couplings are required.
5-axis CNC machining can be indexed or continuous. In the case of indexed milling, the part is automatically positioned to allow the tools to perform the first milling operations. Additional movements are made between milling steps without removing the part from its support.
In the case of continuous milling, the machine can move simultaneously in all directions while cutting the part.
Both of these 5-axis processes eliminate the added cost and potential human error of manually repositioning a part. Because of these advantages, 5-axis machining is the best solution for complex components but is still more expensive than conventional 3-axis CNC milling.
What are the key controls for quality design?
CNC machining is the best manufacturing method when you need simple parts with tight tolerances, excellent mechanical properties, and scalable low-volume production. To make the most of each of these strengths, you need to consider several key factors during the design process:
- What size and shape drill bit can I use?
- Is this tool suitable for my machining project?
- How intense will the vibrations be?
- How will the heat from the bit affect the material I’m working with?
Advantages of using CNC digital cutting machines
The difference between CNC cutting machines and ordinary manual and semi-automatic cutting equipment in the processing of parts is that CNC digital cutting machines automatically process parts according to the program, while manual cutting equipment and Ordinary semi-automatic should be operated by humans. Just change the control of the machine tool. The program can achieve the purpose of processing different parts. Therefore, CNC digital cutting machines are particularly suitable for processing small batches of parts with complex shapes and high precision requirements!
Since CNC digital cutting machines need to process the parts according to the program, the programmer will input the program into the CNC system to direct the work of the machine tool after the program is compiled. The program input is through the control way. In this way, the use of the numerical control system to control the finished parts can be changed by the drawing personnel in time, and its use is freer. The precision of parts and components is also greatly improved by compared to the precision of semi-automatic cutting equipment!
