In industrial processing, microhole machining (generally defined as drilling operations with a hole diameter of ≤1 mm, and holes with a diameter of ≤0.1 mm are categorized as ultra-microholes) has long been recognized as a well-known pain point in the industry. Traditional processes such as conventional mechanical drilling, electric discharge machining (EDM) drilling, and chemical etching drilling either fail to meet high-precision requirements, suffer from low processing efficiency and material damage, or cause environmental pollution, and cannot adapt to the stringent requirements for microhole machining in modern manufacturing. The emergence of modern laser drilling technology has completely solved this long-standing microhole machining challenge. With its unique technical advantages, it has become the preferred solution for microhole machining and is widely used in many high-end manufacturing fields.

The core advantages of modern laser drilling technology are summarized in four key aspects: precision, speed, cost-effectiveness and versatility, which comprehensively solve the pain points of traditional microhole machining:

1.High precision and strong controllability: Laser drilling can focus a laser beam into an extremely small spot with a diameter of less than 0.001mm, with processing accuracy up to ±0.001mm. It can easily complete microhole machining ranging from 0.001mm to 1mm, featuring uniform aperture, no taper and no burr, which is far superior to traditional processes. Through the computer numerical control (CNC) system, parameters such as laser power, pulse width and drilling speed can be adjusted accurately to produce microholes of different apertures and depths, meeting the processing demands of various industries.

2.High processing efficiency, suitable for mass production: The processing speed of laser drilling is much faster than traditional processes, and it can complete dozens to hundreds of holes per second. The efficiency advantage is even more obvious for group hole machining, which can greatly improve enterprises' production efficiency and reduce production costs.

3.Low processing damage and high product qualification rate: Laser drilling adopts a non-contact processing mode with no mechanical stress, which avoids material deformation and edge chipping; cold processing technologies such as ultraviolet laser drilling can control the heat affected zone (HAZ) within a few microns, reduce thermal damage to materials, and greatly improve product qualification rate.

4.Wide adaptability and strong versatility: Laser drilling can process multiple materials including metal, non-metal, special materials and so on. Whether it is metal materials such as stainless steel, aluminum, titanium alloy, or non-metal materials such as glass, ceramics, PCB, it can achieve efficient microhole machining. It can also process different types of microholes such as blind holes, through holes and deep holes to adapt to processing needs of different industries.
