CNC Machining Precision Automation Equipment Parts Suppliers

In the long-term and high-intensity production process, how can the manufacturers of CNC machining precision parts of automation equipment ensure that the machining accuracy of automation equipment can be sustained and stable?

1. Select high-precision and high-stability automation equipment
High-precision machine tools: Select high-performance equipment such as graphite five-axis machining machine tools with high-precision five-axis linkage systems. These equipment can achieve high-precision machining of complex parts with an accuracy of 0.01mm, meeting high-precision machining requirements. (Source: Baijiahao)
Stable and reliable mechanical structure: Ensure that the automation equipment adopts a stable mechanical structure and a precise bearing system to improve the operating stability and machining accuracy of the machine tool.
2. Optimize the production environment
Temperature control: During precision machining, the temperature should be controlled at around 20 degrees, and temperature fluctuations should be strictly controlled to reduce the impact of thermal deformation on machining accuracy.
Stable power supply: Use dedicated power supply, add voltage stabilizing devices, and reduce the impact of power supply fluctuations and instantaneous interference signals on CNC equipment.
3. Implement strict daily maintenance and care
Regular cleaning: Clean the machine tool every day, including key parts such as the control panel, spindle taper, and tool, to keep the machine tool dry and clean.
Check the lubrication and cooling system: Regularly check whether the lubricating oil level and coolant are sufficient to ensure that the machine tool has good lubrication and cooling effects.
Preventive maintenance: Regularly perform preventive maintenance on the machine tool, such as checking whether the oil pressure unit pipe has leakage, checking whether all signal lights and abnormal warning lights are normal, etc.
4. Introduce intelligent and automated technologies
Intelligent control system: Use advanced CNC systems and drive control systems to accurately control the motion trajectory and speed of the machine tool to ensure processing accuracy.
Real-time monitoring and intelligent adjustment: Through the real-time monitoring and intelligent adjustment functions of automation technology, timely discover and solve problems to ensure the stable operation of the machine tool.
Apply AI and machine learning: Use artificial intelligence and machine learning technologies to optimize the operation mode and parameter settings of the machine tool, predict and prevent potential failures, and improve processing accuracy and stability.

How do suppliers of CNC machining precision parts for automation equipment select and optimize tools and fixtures for different types of precision parts processing?
1. Selection and optimization of tools
Select tools according to material characteristics:
Different types of materials (such as aluminum alloy, stainless steel, cemented carbide, etc.) have different requirements for tools. For example, when machining cemented carbide, you need to choose tools with high hardness and wear resistance.
The selection of tool materials is also crucial. Commonly used tool materials include high-speed steel, cemented carbide, ceramics and diamond, etc. Each material has its applicable processing range and characteristics.
Consider processing accuracy and surface quality:
For precision parts requiring high precision and high surface quality, tools with sharp cutting edges, small cutting forces and small vibrations should be selected.
The geometric parameters of the tool (such as rake angle, back angle, blade inclination angle, etc.) also need to be precisely designed according to the processing requirements to reduce cutting forces, reduce cutting temperatures, and improve processing accuracy.
Optimize tool paths and cutting parameters:
Use CAD/CAM software for tool path planning to ensure short tool paths, high cutting efficiency, and stable processing quality.
According to the processing material and tool characteristics, reasonably set cutting parameters such as cutting speed, feed rate and cutting depth to achieve an efficient and stable processing process.
2. Selection and optimization of fixtures
Ensure the positioning accuracy of workpieces:
The design of the fixture should ensure the accurate positioning and stable clamping of the workpiece during the processing. Use precision positioning pins, positioning holes and positioning surfaces and other components to improve the positioning accuracy of the workpiece.
For workpieces with complex shapes, combined fixtures or special fixtures can be used to achieve multi-degree-of-freedom clamping and positioning.
Improve the rigidity and stability of the fixture:
The structural design of the fixture should have sufficient rigidity to resist cutting forces and vibrations. Use high-strength materials, suitable structural forms and appropriate reinforcement structures to improve the stability of the fixture.
For large or heavy workpieces, the support structure of the fixture should be more stable to prevent deformation and vibration during processing.
Achieve rapid clamping and replacement:
In order to improve production efficiency, the design of the fixture should facilitate rapid clamping and replacement. Use modular design or standardized interfaces to reduce clamping time and improve production flexibility.
Introduce automated control systems, such as CNC systems or pneumatic/hydraulic systems, to achieve automatic adjustment and positioning of fixtures, further improving production efficiency.
Consider the versatility and specificity of fixtures:
For different types of precision parts processing requirements, the design of fixtures should take into account both versatility and specificity. General fixtures can meet the processing requirements of a variety of workpieces, but may compromise on processing accuracy and efficiency; special fixtures are designed for specific workpieces and have higher processing accuracy and efficiency.
Suppliers should flexibly select and adjust the design of fixtures according to specific processing requirements and market changes.
