Market demands are constantly changing. To better adapt to these rapid changes, manufacturing technology is constantly being updated and improved. To remain competitive, manufacturers must keep pace or risk getting lost in the process of industrial modernization. Although the process of technological modernization can definitely be painful, it is crucial for the long-term development of companies. In this article you will learn more about micromilling technology.

A comprehensive overview of micromilling

Micro milling-2

Micromilling is a process for machining mechanical parts. Not only does it follow general editing laws, but it also has its own peculiarities. At present, micro-milling technology is not very mature compared with traditional and conventional cutting technology. The aspect of micromilling developed rapidly. Simple features of 2D and 2.5D parts, even 3D curved surfaces of complex parts, can be machined well on CNC machining centers. Microcutting technology is widely used in processing fine products with good adaptability and high productivity. At present, micromachining technology can achieve high machining precision and fine size, and has become an extremely important solution in the field of machining.

Requirements for micromilling machines

Since several elements work in a coordinated manner in series, a machine can only work as well as its weakest individual part. Micromilling requires higher tolerances than traditional milling, where each machine part must meet unique tasks.

Machine geometry

The geometry of a machine is one of the most important factors in its overall performance. Geometry ultimately determines stiffness, precision, thermal stability, damping properties, workload and ease of use. There are currently two common types of vertical machine geometry: bridge structure and C-frame. Each of them has its own advantages and disadvantages.

In most cases, the C frame would have ideal stiffness for micromachining because stiffness directly determines accuracy. In the C frame design, the principal axis or Z axis is the only axis of motion. This would make it lighter and have better dynamic rigidity.

In the bridge structure, the X and Z axes are suspended above the X-axis platform. Therefore, the bridge supports more weight but provides less dynamic stiffness for micro-milling. The bridge structure is best suited for high-speed machining of medium to large parts that typically require maximum Z travel.

It should be noted that vibration is a more destructive processing characteristic when milling small and delicate parts. For example, stiffness and damping are the main factors that must be controlled in micromilling. Machine tools with greater damping reduce and absorb more vibrations caused by cutting. Many machine structures are made from iron or steel welds.

Driving and movement

Today, there are many types of drive and motion technologies in the world. And ball screw technology is a typical type for most machine tools. The combination of ball screw and servo motor technology is still a good solution for micro-milling today.

Multiaxis

Today, multi-axis machining is driving the continued growth of micromilling applications. The typical case is the use of 5-axis CNC machining for miniature wheels. 5-axis machines can handle small tools with tilt options without the need for multiple tools to achieve better surface quality. When it comes to applying traditional 5-axis applications compared to micro-milling, micro-milling has higher requirements for flexibility in controlling tool orientation and can track the stock model in multiple dimensions.

The application of micromilling

Micromachines such as microsatellites, aircraft, machine tools, turbogenerators, vehicles, weapons, etc. have a large market in national defense and aerospace. Cameras, cell phones, etc. are becoming smaller and smaller, but their functionality is constantly improving. Miniaturization is also being driven in measurement technology, biomedicine, electronics and computers, instrument technology and other areas. Micromedical robots, microcomputers and microprecision instruments are direct applications of microprocessing. Therefore, micromilling technology would obviously have great prospects and play an important role in promoting product development and production.
