Discussion on the Composition and Main Applications of Nylon Wheels

尼龙轮是磨料磨具的重要分支产品，是继砂带砂轮等强切削研磨产品之后的研磨产品。尼龙轮主要由尼龙纤维网、研磨介质（矿砂）、粘结树脂等主要成分组成，一般为刚玉和碳化硅，磨削金属通常选用刚玉，磨削硬脆材料或木材选用碳化硅。其中可能添加吸热助剂、填料、色料等各种助剂。粒度越粗，磨削效率越高，其磨削表面的纹路越粗，光洁度也越低，其相对应的网状纤维结构越蓬松。密度大要比密度小纹路更清晰，并且不易发生纹路倾斜、中断。Nylon wheels are an important branch product of abrasive tools, and are grinding products after strong cutting and grinding products such as abrasive belts and grinding wheels. Nylon wheels are mainly composed of nylon fiber mesh, grinding medium (mineral sand), bonding resin, and other main components, generally consisting of corundum and silicon carbide. For grinding metal, corundum is usually used, while for grinding hard and brittle materials or wood, silicon carbide is used. Various additives such as heat absorbing additives, fillers, and pigments may be added. The coarser the particle size, the higher the grinding efficiency, the coarser the lines on the ground surface, the lower the smoothness, and the looser the corresponding Reticular fiber structure. High density has clearer patterns than low density, and is less prone to tilting or interruption of patterns.

Nylon wheels have characteristics such as elastic grinding, cold cutting, and anti blocking. More delicate, soft, and shiny than the same grain size grinding wheel and sand belt lines. It has stronger cutting force and clearer lines than cloth and hemp wheels. Therefore, nylon wheels are often used for grinding wheel sanding, belt sanding, as well as electroplating and mirror polishing pre-treatment. Therefore, nylon wheels are also important grinding tools for surface conditioning, and the processed lines have good ornamental properties, which are widely used in the post-processing of household hardware products.

The main application range of nylon wheels:


1. Metal products such as stainless steel knives and scissors, tableware, and insulated cups


2. Treatment of precious metals such as clock accessories, case straps, jewelry, etc


3. Surface treatment of golf clubs and ball heads


4. Deburring of the surface of hardware castings


5. Architectural Hardware, Hinges and Locks


6. Hardware lighting products and accessories


7. Aluminum bicycle frame rim polishing


8. Wire drawing of VCD panel and Mobile phone case


9. Hardware bathroom products


10. Surface wire drawing treatment of electroplated products


11. Deburring of aluminum heat dissipation fins


12. Stainless steel pipe and strip surface tension pattern


13. Metal medical devices


14. Deburring of Automobile Wheel Hub


15. Titanium alloy blades


Nylon wheel products have a wide range of applications in the fields of polishing and polishing. According to material classification, it can be used for surface treatment of various metals such as stainless steel, aluminum alloy, copper, titanium alloy, cast iron, carbon steel, etc. There are also significant differences in application between the laminating wheel and the winding wheel. Compared with the winding wheel, the laminated wheel has stronger cutting force and is more economical, and is easy to install. However, the lines are thicker, the glossiness, and the lifespan are not as good as the winding wheel. Mainly used for polishing and sanding purposes with certain surface requirements but not very high requirements. The tightening wheel has finer, brighter lines and better lifespan, mainly used for deburring and fine surface treatment. The use of the tensioning wheel requires flange installation on the equipment, therefore there are certain requirements for the equipment.


The impact of the rotational speed of the grinding wheel on the processing results of the workpiece and the lifespan of the grinding tool: When the workpiece material is hard and the surface treatment effect requires high rotational speed, the lifespan of the grinding tool will be correspondingly reduced; The workpiece material is relatively soft and low-speed is selected, resulting in relatively rough surface treatment results.


The influence of feed speed on local patterns of the workpiece: the faster the feed speed, the shorter the time for local grinding, and the fewer number of pattern segments; The slower the feed speed, the longer it takes to process local patterns.


The pressure when grinding the workpiece with a grinding wheel: When the pressure is high, it is easy to burn the workpiece, and the grinding wheel (nylon wheel) will change its shape; When the pressure is low, the pattern of the workpiece is not clear enough and the efficiency is not high enough. Usually, the pressure on the grinding wheel of the flying wing type is relatively low, while the pressure on the winding wheel is higher.


Nonwoven fabric abrasive discs can be used in water, oil or other corrosive environments, without worrying about problems such as steel ball rust and ordinary sandpaper sanding, and can be used with pallets or directly by hand. When there are high requirements for the surface, grinding wheels are often used in conjunction with some lubricants, which can effectively dissipate heat, improve surface color, and reduce dust.
