The machining cycle of CNC turning parts is influenced by various factors, so the time span may have significant differences. Generally speaking, the following aspects are the key factors that determine the length of the processing cycle:
The complexity of the parts: Simple shaft parts may only take a few hours to complete processing. For example, a regular cylindrical shaft only requires outer circle turning and end face turning, and the machining cycle may take 1-2 hours. But if it has complex shapes, such as multiple shafts with different diameters and lengths, or features such as threads, grooves, and conical surfaces, the machining cycle may be extended to several days or even longer.
Material characteristics: Materials with high hardness or difficult to machine will increase cutting time. For example, processing stainless steel materials usually takes more time than processing ordinary carbon steel.
Precision requirement: The higher the precision requirement, the more measurements and adjustments are required during the machining process, thereby extending the machining cycle. For example, parts that require tolerances at the micrometer level may require multiple precision turning and measurements, and the processing cycle may be several times longer than parts with general precision requirements.
Performance of equipment and tools: Advanced CNC lathes and high-quality tools can improve machining efficiency and shorten machining cycles. On the contrary, outdated equipment and low-quality cutting tools may lead to slow processing speed and even require frequent tool replacement, thereby prolonging processing time.
Batch size: The processing cycles for single piece production and batch production are different. During mass production, production efficiency can be improved by optimizing processes and fixtures, while single piece production is relatively time-consuming.
Programming and debugging time: Programming complex parts may take several days, and debugging before formal processing also requires a certain amount of time.
Taking into account the above factors, the machining cycle of CNC turning parts varies from a few hours to several weeks. For example, a part with moderate complexity, moderate precision requirements, and the use of common materials (such as 45 steel) may have a processing cycle of 1-2 days for small-scale production on a medium performance CNC lathe.
The processing cycle of CNC Turned Parts varies due to various factors:
1. Basic processing cycle
The processing cycle of aluminum alloy CNC Turned Parts machining parts is generally 10-15 days. If it’s too long, it could even take over 20 days.
2. Influencing factors
2.1 Model complexity
Complex CNC Turned Parts models require more programming and processing time, resulting in relatively longer processing cycles.
2.2 Materials
The processing difficulty and speed of different CNC Turned Parts materials vary, for example, aluminum may have a faster processing speed compared to other metals.
2.3 Surface treatment
If CNC Turned Parts choose to undergo surface treatment (such as anodizing, spraying, etc.), it will increase additional processing time and may lead to an extension of delivery time. Not doing surface treatment can save 2-3 days of time.
2.4 Business level of production line
If the production line is busy or there are a large number of orders, it may lead to an extension of delivery time.
2.5 Tool wear
The degree of tool wear can affect the machining accuracy and speed of CNC Turned Parts, requiring regular tool replacement, which can also increase machining time.
2.6 Equipment performance
The performance and condition of the CNC machine tool used can also affect the processing time. Large and complex models may require more powerful equipment to support, and the maintenance status of the equipment can also affect its processing efficiency.
3. Precautions
Before starting CNC machining, detailed design documents or 3D models need to be provided to the machining manufacturer.
The beginning of the processing cycle is usually calculated from the receipt of the complete design file or 3D model.
