nylon wheel
Nylon wheel is a kind of abrasive abrasive tools, the product in the field of grinding, polishing has a wide range of applications, such as golf clubs, ball head surface treatment, metal castings surface deburring, building hardware, hinge hinges and locks.
Nylon wheel types are 3P, 5P, 7P, 9P, 12P, 15P and so on, the product sand number is generally divided into 90#, 120#, 150#, 180#, 240#, 320# and so on.

introduction
Nylon wheel is an important branch of abrasive tools products, after abrasive belt grinding wheel and other strong cutting grinding products. Nylon wheel products are mainly composed of nylon fiber net, grinding medium (mineral sand), bonding resin and other main components, which may add heat absorption additives, fillers, color materials and other additives.
Nylon Wheel products are mainly divided into two types: the Unitized Wheel (FIG. 1) and the Convolute Wheel (FIG. 2). The composite wheel is made of industrial cloth (Nylon Prebond) through the method of roller coating (glue containing binder and abrasive, etc.) coated with a piece of stacked press combined in the oven baking curing, and finally cut. The winding wheel is coated by the same method, and is rolled into a rod on a special tube core, and baked and cured.
Nylon wheel products are mechanically supported by nylon Web 3D network. The grinding workpiece has the characteristics of elastic grinding, cold cutting and blocking prevention. It is more delicate, soft and bright than the abrasive belt line of the same size grinding wheel. The cutting force is stronger than cloth wheel and hemp wheel, and the lines are clearer. Therefore, nylon wheel is often used for grinding wheel belt after sanding and electroplating and mirror finish. Therefore, nylon wheel is also an important tool for Surface conditioning, which has good ornamental lines and is widely used in household hardware products.
Product application
Combined with the above characteristics of nylon wheel products, nylon wheel products have a wide range of applications in the field of grinding and polishing. According to the material points, can be used for stainless steel, aluminum alloy, copper, titanium alloy, cast iron, carbon steel and other metal surface treatment.
The application of the superimposed wheel is also different from that of the winding wheel. Compared with the winding wheel, the cutting force of the composite wheel is stronger and more economical, convenient installation, but the line is thicker, glossiness and life is not as good as the winding wheel. Mainly used for the surface has certain requirements but the requirements are not very high sanding use. The winding wheel has finer lines, brighter lines and better life. It is mainly used for deburring and fine surface treatment. The use of the winding wheel needs to be matched with flange installation and equipment, therefore, there are certain requirements for equipment.
According to the specific application classification, the main applications of nylon wheel are listed as follows:
1. Metal products such as stainless steel knives and scissors, tableware, thermos cup
2. Watch accessories, watchcase watchband, jewelry and other precious metal processing
3. Surface treatment of golf clubs and ball heads
4. Deburring the surface of hardware castings
5. Building hardware, hinge hinge and lock nylon wheel
6. Hardware lighting products and accessories
7. Polishing of aluminum bicycle frame rim
8. Drawing VCD panel and mobile phone shell
9. Hardware bathroom products
10. Surface drawing treatment of electroplating products
11. Deburring aluminum heat sink
12 stainless steel pipe strip surface tension
13. Metallic medical instruments
14. Deburring automobile wheel hubs
15. Titanium alloy blades
Product series
It is very important to know the nylon wheel product line for choosing and using nylon wheel. Nylon wheel product series according to abrasive particle number, density and size have very fine distinction. The domestic nylon wheel is usually separated by abrasive grain size, grain size is often between P120 ~ P400. According to density (commonly known as hardness in China), it is widely used in 2P ~ 12P,9P,7P and 5P. The size is generally in inches as a unit, commonly used in the domestic outside diameter of 8 ", 10 ", 12 ", foreign small size superimposed wheel for a wide range of, such as 2 ", 3 ", 4 ", 6 ", thickness from 1/2 "to 2" more, there are also 3 "~ 5" products.
Product safety
Nylon wheel products are polished under high speed rotation, so there is the risk of rotation rupture. Nylon wheel manufacturers need to strictly test the safety of their products before allowing them to be marketed. The most important safety indicator is the Rotation Failure Speed. The manufacturer determines the Maximum operating Speed (MOS: Maximum Operation Speed) for the customer application by testing the rupture speed of a large number of products. The rupture speed of 8 "composite wheel is generally above 8000RPM, but the specified MOS is 3200RPM. For 12 "products, MOS is generally specified at 2400RPM. For 14 "products, such as the use of more than 2400RPM, rupture risk is very large, must be careful when using.
