Q: Can CNC machines, as an advanced processing equipment, process all types of materials?
A: Although CNC machines are widely used in manufacturing, not all materials can be processed by CNC machines. Here are some materials that cannot be processed with CNC machines and the reasons why:
Q: What materials cannot be machined with CNC machines?
Answer:
Plate ductile iron: Plate ductile iron has a high surface hardness, and the tool is prone to serious wear and tear during machining, and the cutting effect is not good.
Cast iron: cast iron is easy to produce scratches in the machining process, and easy to overheat resulting in unstable surface organization, affecting the quality of parts.
Nickel alloy: nickel alloy surface hardness, cutting difficulty, easy to cause tool wear, process difficulty.
Titanium alloy: titanium alloy density, high hardness, easy to produce high temperature, high heat when cutting, sharpening problem is serious, processing difficulty.
Ductile Iron: Ductile iron contains a lot of silicon and chromium, high hardness, easy to damage the tool during machining, poor surface quality.
Q: What is the working principle of CNC machine tools?
A: CNC machine tools work on the principle of computerized control. The computer in the CNC unit processes the information recorded by the input device in the form of numbers and character codes, and then sends commands to the machine spindle and feed actuators through the servo system and the programmable controller. The main body of the machine completes the machining of the workpiece in accordance with these instructions. The entire machining process is carried out automatically according to the pre-programmed machining program.
Q: What are the applications of CNC machine tools in the manufacturing industry?
A: CNC machine tools have a wide range of applications, covering a variety of fields such as machinery manufacturing, aerospace, automotive manufacturing, mold manufacturing, medical equipment, electronics manufacturing and so on. With its high precision, high efficiency, high stability and high flexibility, CNC machine tools play an important role in these industries, and are able to process a variety of complex parts and improve processing efficiency and processing quality.
Q: What safety matters do I need to pay attention to when operating CNC machine tools?
A: When operating CNC machine tools, you need to pay attention to the following safety matters:
Ensure that the machine tool is turned off and the power plug is unplugged to avoid the risk of electric shock.
Check that all parts of the machine tool are in good condition, such as tools, fixtures, guards, etc.
Check whether the lubrication system is working properly and make sure that the oil quality, oil quantity and mounting device of the oil tank and lubrication device are good.
Wear good working clothes, safety shoes, working cap and protective glasses, gloves are not allowed to operate.
Familiarize yourself with the safety operation procedures of the machine tool and the location of the emergency stop button.
Ensure that the workpiece is firmly clamped to avoid dislodging or shifting during machining.
The tools used should match the specifications allowed by the machine tool, and tools with serious breakage should be replaced in time.
During the machining process, pay close attention to the running status of the machine tool and adjust the parameters in time to ensure the machining quality.
It is forbidden to touch the tip of the tool and the iron chips by hand, and the iron chips should be cleaned up with iron hooks or brushes.
During the operation of the machine tool, the operator shall not leave his post, and stop the machine immediately when abnormal phenomenon is found.
Regularly check the maintenance of the machine tool to ensure that the machine tool and the environment are in a clean state.
By observing the above safety regulations and operating procedures, we can ensure operational safety, processing quality and normal operation of the machine tool.
Conclusion:
CNC machines, while powerful, are not suitable for all materials. Understanding which materials can not be processed with CNC machine tools, as well as the working principle of CNC machine tools and safety precautions, is essential to ensure processing quality and operational safety. I hope this article can help readers better understand and use CNC machines.
