Where can laser micro-hole processing be applied

 In the field of traditional processing, micro-hole processing has always been a difficult problem. It is between traditional processing and micro-hole processing. The materials used for etching micro-hole processing are metal materials, mainly made of stainless steel 304 materials and copper and copper alloy materials. In the micro-hole processing of stainless steel, the following parameters should be paid attention to: When the etching process solves the problem of micro-hole processing, the necessary part must be limited by the thickness of the material. In general, the aperture to be processed is 1.5 times the thickness of the material used. If the aperture is larger than the aperture, the etching method is not suitable for processing micro-holes. Due to the extensibility of current chemical corrosion drugs, it can no longer meet the needs of corrosion.

Nowadays, micropore processing products are widely used in precision filtration equipment. Chemical fiber spinnerets, jet engine nozzles, computer print heads, printed circuit boards, TV baffles, planetarium star plates, aviation gyro instrument components, aircraft turbine parts processing blades and red blood cell filters in medical equipment. From the perspective of different sizes, there are more than 50 kinds so far, and each processing method has its own advantages and disadvantages, which are mainly determined by factors such as the size of the workpiece aperture, the arrangement of the holes, and the density. The requirements for cavity and cavity accuracy and the subsequent use of the workpiece, including consideration of which processes can be processed in batches.

Conventional or imaginable micro-hole processing methods include: stamping, which is mainly used for products with a hole diameter of 1.0mm or more and a material thickness of 0.5mm or less. It is mainly used for workpieces with fewer holes because the encrypted parts punching die cannot be realized. CNC punching and CNC punching are a more popular process in recent years, and CNC punching has high processing efficiency. Its advantage is low cost. CNC punching requires the replacement of the corresponding punch to operate, and no mold is required. CNC punching is mainly used for large and low-density workpieces. NC punching has no benefit for workpieces with a hole diameter less than 0.5mm.
