Digital control of the mold processing

In recent years, the development of the mold industry has maintained a good momentum. The overall orders of mold companies have been sufficient. In the first half of the year, mold sales exceeded 80 billion yuan, an increase of 21% over the same period of the previous year.

The digital control of the mold processing equipment, the non-patterning of the mold design, and the informatization of the mold management have enabled the mold company to reach a higher level, and the overall mold level has been significantly improved. Modern manufacturing requires the mold industry to upgrade the mold technology content, speed up the pace of structural adjustment, and adapt to the upgrading of new products.

Not only is the iPod getting smaller. Computers and televisions are also constantly getting thinner. Advances in medical equipment have enabled more and more miniature devices to be installed in our bodies; even a small camera can walk through the body. Not only are things getting smaller, they are being assembled with more parts that provide extra power and functionality. Micro-parts have a wide range of applications in the aerospace, automotive, biomedical, electronics, information technology optics and telecommunications industries. All of these products are being developed with higher requirements for small parts and products.

Microsystem technology has become one of the fastest growing industries in the world, and there is a large demand for industries that need to manufacture small, high-precision parts, such as bio-medical equipment, optics, and microelectronics, including mobile communications and computer components. . Parts requiring micro-system machining have an accuracy of 5 mm or less and a surface quality of 0.2 mm or less, and the hardness of the parts is also 45 HRC or higher.

Micro-milling is a new processing technology for machining small parts and high-precision parts. Using very small tools (less than 0.1mm in diameter) and achieving very small surface tolerances and high quality surface accuracy, part deformation, increased complexity, the need to machine small features with high precision, and the use of micron-scale Special tools. For example, a workpiece with a diameter of 0.1 mm meets the above requirements in order to obtain a curved surface with high precision. The micro-milling technology needs to achieve the following support: a small-diameter cutter of 100 mm or less; a profile ratio (L/D) of 10 or a high speed of up to 100 Tool; 150000r/min or higher spindle speed; 0.1mm or less machining tolerance; ability to correct geometry.

Challenges associated with micro-milling include the use of micro-tools with a diameter drop of 100 micrometers (μm) or less and operating at very high speeds of up to 150,000 rpm. The surface quality (Ra) needs to reach 0.2 microns. For the dimensional accuracy of micro-mold and micro-machining tools and the high quality requirements of product surface topography, Shanghai Volume Bo Industrial Co., Ltd. specializes in providing multi-component, measurement solutions to help companies in the original design, development cycle, product quality, in-service testing And other aspects significantly improve efficiency and reliability.
