There are many aspects to customizing CNC parts, but here are some key points:
First, preliminary preparation and communication
Get in touch and communicate details:
Get in touch with CNC processing plants through appropriate means (such as friends, online platforms, etc.).
Send drawings or bring the case sample to inquire and communicate the intention of cooperation.
Confirm whether the CNC processing plant has the appropriate processing capacity for custom machining parts orders.
Confirm that the CNC factory quotes for custom parts are in line with the company budget.
Confirm whether the CNC processing plant’s delivery period for customized parts meets the project process.
Drawing design and requirements:
Drawings, as key technical documents, should provide the geometric dimensions, shape information, processing technology, quality requirements and design intent of the parts.
Drawings must contain dimensional and geometric requirements, material specifications, tolerances, surface requirements, assembly requirements, quantities, graphic representations, part legends, and other necessary parameters.
Sign machining contract:
The signing of the contract and the payment for goods are a constraint for both parties to ensure that both parties complete the delivery of the machining order as agreed.
Second, processing control
Equipment inspection and preheating:
Before processing, each part of the CNC machine should be thoroughly checked to confirm that the fasteners are not loose, and the key parts such as bearings and motors are operating normally.
For CNC machines that need to be preheated, preheat according to the manufacturer’s instruction manual to ensure that the equipment can show the best performance and accuracy after reaching the best operating temperature.
Program testing and simulation:
Before any actual machining, the written CNC program should be thoroughly tested using simulation software to detect programming errors and avoid material waste and equipment damage.
The actual performance of the CNC program is checked by dry runs (runs without cutting material) to ensure that all mechanical actions are as expected.
Correct clamping and positioning:
The selection of appropriate fixtures and clamping devices can not only firmly fix the workpiece, but also prevent the workpiece from displacement or deformation during processing.
Use precise positioning methods to ensure the precise position of the workpiece, such as tool setting and fixture positioning systems.
Tool selection and use:
Select the most suitable tool according to the material type, hardness and specific requirements of the workpiece.
Check the wear of the tool regularly, and replace the tool with serious wear in time to avoid the deterioration of the processing quality or unnecessary processing problems.
Optimization of processing parameters:
Select the right machining parameters, such as cutting speed, feed rate and cutting depth, which are adjusted according to the workpiece material, tool type and machine characteristics to achieve the best machining efficiency and surface quality.
Monitor vibration and temperature during processing and adjust parameters appropriately to reduce vibration and control temperature rise.
Third, environment and security
Keep the working environment clean and orderly:
Ensure that the working environment around the CNC machine is clean and well-ventilated.
When handling operations containing dust or toxic gases, appropriate ventilation measures should be taken.
Strict compliance with safe operating procedures:
Operators must wear appropriate personal protective equipment, such as safety glasses, earplugs, gloves, etc.
Follow all relevant safety procedures to ensure operator safety.
Fourth, quality control and maintenance
Perform regular maintenance and calibration of CNC machines:
Ensure the precise movement of each shaft and reverse clearance control within a reasonable range to maintain the high precision machining capability of the equipment.
Strict quality check:
Strict quality inspection of the completed workpiece, including dimensional accuracy, surface roughness and other indicators to ensure that each product meets the technical specifications.
Continuous improvement:
Continuous improvement of process and technology through regular review and analysis of problems and challenges in the process to improve process quality and efficiency.
In summary, customized CNC parts need to pay attention to many aspects such as preparation and communication, processing control, environment and safety, and quality control and maintenance. Only comprehensive consideration of these factors and strict implementation of the relevant requirements and procedures can ensure that the quality and efficiency of customized CNC parts meet the requirements.
