The mechanical keyboard is loved by young people because of its excellent feel and quality. The mechanical keyboard has a longer service life than the ordinary membrane keyboard, which is about 10-20 years with proper maintenance. The mechanical keyboard is easy to realize the function of full keyboard keys without conflict. Mechanical keyboard has high playability. Of course, everything has two sides. Mechanical keyboards are expensive, waterproof and heavy. Although the mechanical keyboard has shortcomings, it does not prevent young people from pursuing it.
Structure Of The Mechanical Keyboard
1. The structure of mechanical keyboard includes three parts: key cap, mechanical shaft and case.
2. The key cap is often made of acrylonitrile butadiene styrene (ABS), polybutylene terephthalate (PBT), polyformaldehyde (POM), nylon and other materials.
3. The mechanical axis is the core of the mechanical keyboard, and is the key of the mechanical keyboard. Different axes have different feel of keys.
4. The case of mechanical keyboard is usually made of aluminum alloy and plastic. This case can be machined with CNC machining.
Precautions For Aluminum Case Of Mechanical Keyboard CNC Machining
1. First of all, we choose appropriate materials for processing: In order to ensure a good feel and appearance of the mechanical keyboard, Hassful HASSFULL recommends selecting AL6061-T6 aluminum and AL6063-T6 aluminum materials. These two types of materials are also relatively cheap for processing. The material grade is divided into new materials and secondary materials. The aluminum case of the mechanical keyboard needs to be sandblasted. The aluminum content of AL6063 is higher than that of AL6061. The new national standard AL6063 is a better choice. This model can achieve a higher texture.
2. Precautions during processing: considering the product volume and processing time, we choose 20 milling cutter at the machine adjustment stage to increase the Z-axis feed, so that the processing efficiency can be increased by 30%; In order to ensure the surface quality of the aluminum case of the mechanical keyboard, and minimize the surface knife marks and joint marks, we reduce the number of tool receiving times. The R angle of the art line is finely trimmed, and PCD finishing knife is used for one-time processing.
3. After machining the aluminum case of the mechanical keyboard by the machining center, this is only a semi-finished product. We need to manually use 400 # sponge to clean the acute angle to prevent the acute angle from being smoothed after oxidation and prevent the oxide layer from falling off.
4. In addition, we will clean with pure water to prevent cutting fluid corrosion.
Through the above analysis, we have a relevant understanding of the mechanical keyboard. Its case can be processed by Hasfu F90 precision machining center. The maximum size of the equipment is 900 × 650mm, very suitable for processing various aluminum plates. In addition, the movable beam type enclosure structure adopted by the equipment has the characteristics of small floor area, which can prevent debris splashing and ensure the safety of operators.
