In mold manufacturing, Ball Knife plays an important role in the processing of complex cavities with its unique tool shape and processing characteristics.
1. Characteristics of Ball Knife
Ball Knife, especially ball-end milling cutter, has small cutting force and tool tip angle, and its tool tip is arc-shaped. These characteristics enable Ball Knife to produce smaller residual marks when processing complex cavities, thereby ensuring the finish and flatness of the processed surface. At the same time, Ball Knife can also effectively reduce vibration and deformation during processing and improve processing accuracy.
2. The process of Ball Knife processing complex cavities
Design processing path:
Determine the processing path of the ball end milling cutter according to the CAD model of the part. In order to ensure the processing quality, the processing path should be as smooth and continuous as possible.
Select appropriate processing parameters:
Including feed speed, cutting speed, cutting depth and cutting angle. The selection of these parameters needs to be determined according to the specific processing material, cavity shape and processing requirements.
Preparation before processing:
The workpiece should be properly preheated before processing to avoid affecting the processing effect due to the appearance of condensed substances. At the same time, it is necessary to check whether the design dimensions of the workpiece, especially the inner cavity surface, meet the requirements.
Processing:
The ball end milling cutter is slowly moved to the inner cavity surface and cut according to the preset processing path. During the processing, the rotation speed and feed speed of the tool need to be kept appropriate to ensure the processing quality and tool life. At the same time, appropriate coolant should be used to keep the temperature of the tool and the workpiece surface stable to avoid deformation or cracks during processing.
Post-processing:
After processing, the parts need to be cleaned and deburred to ensure the quality and surface smoothness of the parts.
3. Advantages of Ball Knife Processing Complex Cavities
High-precision processing:
Ball Knife can process according to the curve of the workpiece surface to achieve high-precision processing.
Multi-axis linkage processing:
Ball Knife can not only process according to the curve of the workpiece surface, but also tilt according to the tangent of the processing surface, thereby achieving the effect of multi-axis linkage processing.
Good surface quality:
The tip of the ball knife has a large arc, which can produce small residual marks, thus ensuring the smoothness and flatness of the machined surface.
In summary, the ball knife plays an important role in the processing of complex cavities in mold manufacturing. Through reasonable processing path design, processing parameter selection and processing process control, the ball knife can complete high-precision and high-quality complex cavity processing.
