Precision Brass CNC Machining Large Parts & Aluminum CNC Machining Parts
Cutting parameters for brass CNC machining or :
1. Cutting speed
Cutting speed refers to the running speed of the cutting edge on the workpiece, which is one of the most basic parameters in cutting processing. For the processing of brass materials, a moderate cutting speed is generally selected, usually between 100-200mm/min. If the cutting speed is too fast, it can cause problems such as thermal deformation and increased wear of the tool; If the cutting speed is too slow, it can lead to low machining efficiency, poor surface quality, and other problems.
2. Feed rate
Feed rate refers to the length of time a tool travels on a workpiece per unit of time. The size of feed rate has a significant impact on machining quality and efficiency. For the processing of brass materials, the feed rate is generally between 0.1 and 0.2mm/r. If the feed rate is too large, it will not only increase tool wear, but also cause vibration, exacerbating the problem of poor surface quality; If the feed rate is too small, it will lead to low processing efficiency.
3. Cutting depth
Cutting depth refers to the depth at which the tool passes over the workpiece during each cutting. For the processing of brass cnc machining, the cutting depth is generally between 0.5 and 1.0mm. Excessive cutting depth not only exacerbates tool wear, but also increases surface residual stress, leading to a decrease in surface quality during machining; Cutting depth too small can lead to long cutting time and reduce machining efficiency.
The precision standards for CNC machining mainly include aspects such as positioning accuracy, repeat positioning accuracy, form accuracy, position accuracy, and dimensional accuracy. The following is detailed information about the precision standards and precautions for CNC machining.
The positioning accuracy of a CNC machining center is one of the important indicators for measuring its precision. Generally speaking, the positioning accuracy requirement of a CNC machining center is within ±0.01 mm.
Positioning repeatability refers to the degree of change in the position of a part after multiple machining operations at the same location. This accuracy requirement is usually within ±0.005 millimeters.
Shape accuracy mainly refers to the deviation between the surface shape of the machined part and the theoretical shape. The shape accuracy requirement is within ±0.02 mm.
Positional accuracy refers to the deviation between the machined surface of a part and the reference surface, and it is required to be within the range of ±0.02 mm.
Dimensional accuracy refers to the deviation between the size of a machined part and the theoretical size, and the deviation is required to be within ±0.01 mm.
Xiamen Yulong Machinery use high-quality raw materials and tools is the key to achieving CNC machining precision parts. Poor-quality materials and tools will affect the precision and surface finish during the machining process. We conduct regular maintenance and upkeep, inspect and replace machine parts and cutting tools to ensure the precision and performance of machines and tools. When selecting appropriate cutting tools and machining parameters can reduce vibration and cutting force during the machining process, thereby improving machining accuracy. Adopting appropriate machining strategies can make the machining process more stable, thereby improving machining accuracy. We use progressive cutting or multiple cutting can reduce vibration and cutting force and regularly conducting accuracy tests and calibrations can check the performance and accuracy of CNC machine tools and make timely adjustments and corrections. Environmental factors such as temperature, humidity, and vibration can also affect the accuracy of the machining center. Maintaining stable environmental conditions helps us improve the machining accuracy.
According to the processing requirements of the parts, selecting appropriate cutting tools, cutting parameters and processing technology can optimize the processing process and improve the processing accuracy.
By following the above accuracy standards and precautions, the quality and efficiency of our CNC machining can be effectively improved, ensuring that the CNC machining large parts meet the design requirements.
