Introduction to Hole Processing Methods - Drilling, Reaming, Countersinking, and Reaming
Drilling The method of processing holes in solid material with a twist drill is called drilling. General processing can be up to the size tolerance grade IT14 ~ IT11, surface roughness Ra value of 50 ~ 12.5μm. Commonly used drilling machines are: desktop drilling machine, vertical drilling machine and rocker arm drilling machines. 1, drilling machine 1) desktop drilling machine referred to as table drill (Figure 1), is a small machine tool, placed in the clamping table to use. Its drilling diameter is generally below 12mm. Mainly used for processing small workpieces on a variety of holes, clamping in the most used. Fig. 1 Benchtop drilling machine 1-Table 2-Feeding handle 3-Spindle 4-Belt cover 5-Motor 6-Spindle holder 7-Column 8 (2) Vertical drilling machine, referred to as vertical drill (Figure 2), is generally used to drill holes in medium-sized workpieces, and its specifications are expressed in terms of the maximum drilling diameter. Commonly used are 25mm, 35mm, 40mm, 50mm, etc...

Chrome-free surface passivation for aluminum alloys
Aluminum alloys are widely used in aerospace, automotive, electronics and other fields due to their light weight, high strength and corrosion resistance. However, the traditional chromate passivation process has been strictly limited by international environmental regulations due to the high toxicity and serious pollution of hexavalent chromium. In this paper, the research on chromium-free passivation technology is carried out to explore the film-forming mechanism of silane/rare earth salt composite system, to improve the corrosion resistance of passivation film by optimizing the process parameters, and to analyze its environmental protection and economic value, so as to provide theoretical and technical references for the alternative chromate process. From this paper, we can learn: The application of aluminum is the highest production of non-ferrous metals, the most widely used metal materials. In the metal structural materials, its production is second only to steel. All-Aluminum Engines The advantage of a cast aluminum block is that it is lightweight,...

Aluminum alloy TIG and MIG welding process analysis: technology comparison, operation points and industry applications
Challenges and Importance of Welding Aluminum Alloys Aluminum alloys are widely used in automotive, aerospace and shipbuilding applications due to their light weight, high strength and corrosion resistance. However, its high thermal conductivity, oxidizability and susceptibility to thermal cracking make the welding process a serious challenge. Take the battery tray of new energy vehicles as an example, the weld needs to be both high strength and airtight, which is difficult to meet the needs of traditional processes, and TIG and MIG welding technology provides an efficient solution for this. Aluminum alloy features: low density: the density of aluminum alloy is smaller than that of steel and copper, about 2.7 g/cm3, so aluminum alloy products are lighter than steel products of the same volume. High strength: Aluminum alloy has high strength and hardness, and its strength and hardness can be significantly improved after heat treatment. Good electrical conductivity: the electrical conductivity of aluminum alloy is better than pure copper and steel...

How many types of aluminum corrosion are there??
Types of Aluminum Corrosion 1. Atmospheric Corrosion The most common form of aluminum corrosion. Atmospheric corrosion of aluminum occurs due to exposure to natural elements. Because of its likelihood of occurring in most places, atmospheric corrosion accounts for the largest share of the total damage to aluminum caused by all types of corrosion combined in the world. Atmospheric corrosion can be categorized into three subcategories. They are dry, wet and moist, depending on the level of moisture in the service environment. Since moisture levels can vary greatly depending on your geographic location, certain areas will experience greater corrosion than others. Other environmental factors that affect the level of atmospheric corrosion are changes in wind direction, temperature and precipitation. The concentration and type of pollutants in the air and proximity to large bodies of water also play an important role. 2.Galvanic Coupling Corrosion When aluminum is physically or through...
