Lots of products involve Computer Numerical Control machining in modern life, because of its versatility and productivity. From a small door lock part to the large scale of aerospace parts production, the CNC machining process can meet the requirements with the programming language, CNC machines, tools and the understanding of CNC machining basics. Check out the advantages and characteristics of CNC machining, 5-axis machining and more.
CNC machining is a subtractive fabrication method to use high speed automated, numerically controlled machines equipped with lots of cutting tools to remove materials from the block for creating designed parts. The CNC machines will move to execute the operations like turning, milling, drilling as the CAM programming instructions, which work with CAD files customer provided.
CNC machining language or CNC programming language is called G-code, which is used in computer-aided manufacturing to control the machine features including speed and feed, location and more, guide the motors where to move, how fast to move, and what path to follow.
1. Strong adaptability and high flexibility
CNC machining process is suitable for a broad variety of components manufacturing, the new CNC machined parts can be produced with new programs and not changing the machines and controller.
2. High precision and top quality
CNC machine tools carry out the processing according to CAM instructions, which eliminates the error caused by manual intervention. Multiple measurements will be taken to ensure high precision and rigidity, dimensional accuracy of the part. The machining accuracy of the CNC machine has increased from ± 0.01 mm to ± 0.005mm or even higher now. In addition, with compensation technology, CNC equipment can achieve higher machining precision than their own, the production consistency of the same batch of precision CNC machining parts is improved, ensures a high qualification rate and stable processing quality.
3. Improved productivity and efficiency
The range of the spindle speed and feed rate of Computer Numerical Control machines is larger than that of traditional machines, so each CNC process can select the optimal cutting amount. What’s more, the rigid structure of the CNC machine allows it to carry out strong cutting of large cutting amounts, which improves the cutting efficiency. There is almost no need to readjust and recheck the machine tool when the processed parts changed. A machine can realize the continuous processing of multiple processes. With faster moving, automatic tool change and shorten clamping time, the production time can be decreased greatly.
4. Suitable for complex parts machining
It’s difficult for traditional manufacturing equipment to realize the movement of a curve or curved surface whose trajectory is more than three times, such as space curved surfaces of propeller and turbine blade, while the CNC machines can move along any trajectories and process curved surfaces of any shape, which allows the processing of complex and special-shaped parts.
5. Economical and cost-effective
Even though the CNC machine and tools are not cheap and even expensive, the CNC machining technologies can save time for marking, adjustment, processing, and inspection, which reduces the cost directly. The stable quality and machining accuracy of CNC machining services also reduced the scrap rate, then save the cost further. Other than that, one machine can realize multiple purposes like the machining center, which saves the workshop area and building investment, brings economic benefits.
5-axis CNC Machining is the process of moving the workpiece or cutting tool along five different axes simultaneously. X, Y and Z cover three of the five axes in 5-axis machining, while the other two include A, which rotates round X, and B, which rotates around Y. 5-axis CNC machining can create more complex products.
Lock parts are commonly used in our life, the mechanical parts of a basic lock including cylinder, bolt or latch, spring bolt, box & strike plate, interior knob & exterior knob, lock button, spring clip, mounting plate, and more. Some of the door lock parts for home or commercial buildings can be produced with the Junying CNC machining services to achieve high precision, the durability of mass production.
