Precision to a thousandth of a millimetre, micromachining technology makes it possible to machine on micro devices

Micromachining technology can be applied to a wide range of materials. These include polymers, metals, alloys and other hard materials. Micromachining technology can be precision machined to a thousandth of a millimetre, helping to make the production of tiny parts more efficient and realistic. Also known as micro-scale mechanical engineering (M4 process), micromachining manufactures products one by one, helping to establish dimensional consistency between parts.

1. What is micromachining technology
Also known as micro machining of micro parts, micro machining is a manufacturing process that uses mechanical micro tools with geometrically defined cutting edges to create very small parts to reduce material to create products or features with at least some dimensions in the micron range. Tools used for micromachining may be as small as 0.001 inches in diameter.

2. what are the micro machining techniques
Traditional machining methods include typical turning, milling, fabrication, casting, etc. However, with the birth and development of integrated circuits, a new technology emerged and developed in the late 1990s: micromachining technology. In micromachining, particles or rays with a certain energy, such as electron beams, ion beams and light beams, are often used to interact with solid surfaces and produce physical and chemical changes to achieve the desired purpose.

Micromachining technology is a very flexible process that allows the production of micro components with complex shapes. In addition, it can be applied to a wide range of materials. Its adaptability makes it particularly suitable for rapid idea-to-prototype runs, the fabrication of complex 3D structures and iterative product design and development.

3. laser micromachining technology, powerful beyond your imagination
These holes on the product have the characteristics of tiny size, intensive quantity and high processing accuracy requirements. With its high intensity, good directionality and coherence, laser micromachining technology, through a specific optical system, can focus the laser beam into a spot of several microns in diameter, and its energy density is very highly concentrated, the material will quickly reach the melting point and melt into molten material, with the continued action of the laser, the molten material begins to vaporise, producing As the laser continues to act, the molten material begins to vaporise, producing a fine vapour layer, forming a three-phase co-existence of vapour, solid and liquid.

During this time, the melt is automatically sputtered out due to the vapour pressure, forming the initial appearance of the hole. As the laser beam irradiation time increases, the depth and diameter of the micro-hole increases until the laser irradiation is completely finished, the molten material that has not been sputtered out will solidify and form a recast layer, thus achieving the purpose of laser unprocessing.

With the market of high precision products and mechanical parts of the micro processing demand is more and more vigorous, and laser micro processing technology development is more and more mature, laser micro processing technology with its advanced processing advantages, high processing efficiency and can be processed material restriction is small, no physical damage and manipulation of intelligent flexibility and other advantages, in high precision precision products processing will be more and more widely used.
