Differences between milling and planing machines
In the grand picture of machine building, metal cutting processing occupies a central position. As the key means to achieve precise shapes and sizes of parts, a variety of machine tools have come into being, and together they have driven the progress of industrial civilization. Among them, milling machine and planer as two types of long history and very strong basic machine tools, in the early stage of shaping the foundation of modern industry played an indelible role. Although they belong to the same category of removing the processing of materials, but its core working principle, applicable processing objects and the embodiment of the characteristics of the process, but there are essential differences. Milling machine, with its rotating multi-flute cutter (milling cutter) as the main feature, through the tool's high-speed rotation and multi-directional feed movement of the workpiece, can be efficiently processed out of the plane, grooves, gear teeth, helical surfaces, and a variety of complex curved surfaces of the wheels ...

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...
