When machining CNC precision parts, there are some important precautions that need special attention:

Design and drawing preparation:

Ensure that the design drawings are accurate and include all necessary dimensions, tolerances, and surface requirements.

Considering the possible limitations and challenges that may arise during the machining process, design the shape and structure of the parts reasonably.

Material selection:

Select appropriate materials based on the functionality and requirements of the parts. Different materials have different mechanical properties and processing characteristics, which need to be selected based on actual situations.

Tool selection and cutting parameters:

Select the appropriate tool type, tool size, and cutting parameters based on material type, part shape, and machining requirements.

Pay attention to the setting of parameters such as cutting speed, feed rate, and cutting depth to ensure machining quality and tool life.

Clamping and positioning:

Choose appropriate fixtures and positioning methods to ensure the stability and accuracy of the parts during the machining process.

Avoid excessive or uneven clamping force to avoid deformation or affect machining accuracy.

Processing sequence and process planning:

Reasonably plan the processing sequence to avoid increasing the difficulty of subsequent processing due to residual stress or deformation during the processing.

Select appropriate processing techniques based on the characteristics and requirements of the parts, such as milling, drilling, thread processing, etc.

Processing monitoring and quality inspection:

During the machining process, timely monitor the machining status, observe the cutting situation and surface quality.

Conduct necessary dimensional measurements and surface inspections to ensure machining accuracy and quality meet requirements.

Tool management and maintenance:

Regularly inspect and replace cutting tools to maintain machining quality and tool life.

Pay attention to the cleaning, lubrication, and storage of the cutting tools to prevent damage or rusting.

Safety precautions:

Comply with safety operating procedures, wear personal protective equipment, and ensure the safety of operators.

Ensure that the machine tool and equipment are in normal working condition and undergo regular maintenance and repair.
