HimachalPradesh-Special-shaped holes refer to holes with different shapes from ordinary round or square holes. Common special-shaped holes include elliptical holes, polygonal holes, irregular shape holes, etc. Because of its complex shape, processing is more difficult, usually need to use special processing technology and tools to process.
The following are some common special-shaped hole processing methods:
Laser cutting: Laser cutting is a non-contact processing method, can achieve high precision special-shaped hole machining. By adjusting the focal length and power of the laser beam, the special-shaped holes of different materials and shapes can be processed.
Electric discharge machining (EDM) : EDM is a method of machining metals by electrical pulse discharge. It is suitable for machining of materials with higher hardness and complex special-shaped holes.
Milling: Milling is a method of machining workpiece by rotating the tool. It is suitable for machining irregular holes of larger size and shallow depth.
Drilling: Drilling is a method of machining the workpiece by rotating the tool and advancing along the axis. It is suitable for machining irregular holes of small size and depth.
In the special-shaped hole processing, it is necessary to choose the appropriate processing method according to the specific shape and material of the workpiece, and pay attention to the maintenance and maintenance of tools and machine tools in the processing process, in order to ensure the processing effect and tool life.
Special-shaped holes are polished by magnetic polisher
The shape of special-shaped hole is special, the surface curvature changes greatly, and the polishing is difficult. However, if the appropriate method and process is adopted, the magnetic polishing machine can be used to polish the special-shaped holes.
The following are some commonly used magnetic polishing methods for special-shaped holes:
Selection of appropriate magnetic abrasive: In order to fully cover the internal surface of the special-shaped hole, and form sufficient abrasive flow in the special-shaped hole, it is necessary to choose the appropriate magnetic abrasive, the appropriate type of grinding steel needle, etc.
Choose the right magnetic polishing machine: In order to achieve good abrasive flow and polishing effect in the special-shaped hole, it is necessary to choose the magnetic polishing machine with good magnetic field control ability and large speed adjustment range.
Appropriate processing process: For special-shaped holes of different shapes, appropriate processing process should be adopted, such as multi-stage polishing, appropriate adjustment of abrasive flow speed and direction, to ensure the polishing effect and quality.
It should be noted that different methods and processes need to be adopted according to the specific situation when the special-shaped hole is polished, and attention should be paid to the quality control and safety issues in the polishing process, so as to ensure the polishing effect and processing quality.
