Stainless steel polishing machine accessories all aluminum wheel

Structural composition
Hub part: The hub of an all-aluminum wheel is its core supporting structure. It usually has a certain thickness and strength and is used to be installed on the spindle of the polishing machine. There is a mounting hole in the center of the hub, and its size and accuracy need to match the specifications of the polishing machine spindle to ensure a firm installation and good concentricity. For example, in some all-aluminum wheels used in industrial polishing machines, the diameter tolerance of the mounting hole of the wheel hub is controlled within a very small range, generally around ±0.05mm, which can effectively reduce vibration during high-speed rotation.
Rim part: The rim is the part that is in direct contact with the polishing medium and the workpiece. Its width and thickness are designed according to different polishing needs. For rough polishing all-aluminum wheels, the rim may be thicker and wider to accommodate more polishing paste and withstand greater pressure; while for fine polishing wheels, the rim may be relatively thin and narrow to facilitate better polishing. Control polishing accuracy. The surface of the rim is usually smooth, and some may have subtle textures that help the polishing medium adhere.
Dimensions
Diameter range: All-aluminum wheels come in various diameters. Small all-aluminum wheels may only be a few centimeters in diameter and are mainly used for polishing small precision workpieces or in polishing equipment with limited space. For example, an all-aluminum wheel used on a jewelery polishing machine may be between 5 - 10cm in diameter, allowing for detailed polishing of small pieces of jewellery. The diameter of large all-aluminum wheels can reach tens of centimeters and are used for polishing large stainless steel products such as stainless steel plates, large tanks, etc. The diameter of these large all-aluminum wheels may be around 30-50cm.
Thickness size: Its thickness is generally in the range of several centimeters. Thinner all-aluminum wheels (such as 2-3cm thick) may be used when the workpiece surface flatness is required and the polishing area is small; thicker all-aluminum wheels (such as 5-8cm thick) can provide more The polishing contact area and better stability are suitable for large-area workpieces or situations where greater pressure is required for polishing.
Working principle and performance characteristics
Working principle: During the polishing process, the all-aluminum wheel is installed on the spindle of the polishing machine. When the spindle drives the all-aluminum wheel to rotate at high speed, polishing paste or polishing fluid is applied to the surface of the rim. The stainless steel workpiece is then brought into contact with the rotating all-aluminum wheel. The polishing medium on the surface of the all-aluminum wheel interacts with the workpiece surface under the action of centrifugal force and friction. Through the cutting, grinding and friction of abrasive particles on the small unevenness on the surface of the workpiece, surface defects are removed and the surface of the workpiece gradually becomes smooth.
Performance features:
Moderate hardness: The hardness of aluminum allows the all-aluminum wheel to effectively remove material from the workpiece surface during the polishing process without causing excessive scratches to the workpiece surface. Compared with metal polishing wheels with higher hardness (such as steel wheels), all-aluminum wheels are more "gentle" when polishing. For some stainless steel workpieces with higher surface quality requirements, such as stainless steel decorative parts, medical equipment, etc., they can provide better Good polishing effect.
Good balance performance: Since the mass distribution of the all-aluminum wheel is relatively uniform and has been precisely processed and balanced during the manufacturing process, it vibrates less during high-speed rotation. Good balance performance can ensure the stability and precision of polishing and reduce defects such as ripples on the workpiece surface caused by vibration. For example, when polishing a stainless steel watch strap, the balancing performance of the all-aluminum wheel can ensure a uniform gloss on the surface of the strap.

Metal material polishing
Stainless steel polishing: In the processing of stainless steel products, all-aluminum wheels are widely used. Whether it is stainless steel tableware (such as spoons, forks), kitchen utensils (such as pots), or stainless steel decorative materials (such as stainless steel plates, stainless steel tubes), all-aluminum wheels can play an important role. For polishing stainless steel tableware, the all-aluminum wheel can effectively remove minor scratches and surface defects produced during the processing. By using appropriate polishing paste, the surface of the tableware can be as bright as a mirror. In terms of stainless steel decorative materials, all-aluminum wheels can be used to polish the outer surface of stainless steel pipes, so that they can show good gloss and texture in fields such as architectural decoration and furniture manufacturing.
Aluminum and aluminum alloy polishing: Since the all-aluminum wheel itself is also made of aluminum, it will not introduce other metal impurities when polishing aluminum and aluminum alloy products. For example, in the processing of aluminum alloy parts in the aerospace field (such as the aluminum alloy skin of aircraft wings) or aluminum alloy wheels in the automobile industry, the all-aluminum wheel can polish the aluminum alloy surface to the required smoothness. , to meet its strict requirements for surface quality.
Copper and copper alloy polishing: In the processing of copper products (such as copper ornaments, copper faucets) and copper alloy (such as brass, bronze) products, all-aluminum wheels also have a place. It can be used with specific polishing media to remove the oxide layer on the surface of copper and copper alloys while improving its gloss. For example, for bronze-colored copper ornaments, all-aluminum wheels can make the surface smoother and enhance its ornamental value while retaining its rustic color.
Polishing of non-metallic materials (in some cases)
Plastic polishing: Some plastic materials with higher hardness (such as polycarbonate, acrylic) may need surface polishing after molding to improve their transparency and gloss. All-aluminum wheels can be an option in this case. For example, in the processing of acrylic sheets, by using fine polishing paste and appropriate rotation speed, the all-aluminum wheel can make the tiny scratches on the surface of the acrylic sheets disappear, improve its optical performance, and make it more suitable for use in advertising displays, lamp casings and other fields. Advantages. However, it should be noted that for some soft plastics, because the all-aluminum wheel is relatively hard, it may cause surface damage during the polishing process, so you need to choose carefully when applying.
