Fiber discs are one of the foremost popular sorts of abrasive grinding and finishing products. When used correctly, they will do precisely about any grinding application that wheels can do — it all comes down to using the proper disc for your application.
Resin Fiber Discs are far and away the top popular coated abrasive product utilized in the industry. Constructed with an important vulcanized fiber back, they're covered with abrasive grains and bonded with a troublesome, heat resistant resin. It leads to a durable, calm, and fast cutting action. The right sort of grinding abrasive is out there, so you'll select the materials best suited to your specific applications. Usually, only the diameter, grain size, and mineral type need to be specified.
Resin fiber discs are available in multiple styles. Variances include the diameter, the arbor hole size, the form of the disc, and the arbor hole's shape.
The abrasive grain is what's doing the addition of any abrasive product. The grain utilized in a fiber disc determines the disc's cutting speed, life, and cost-ratio. There are four types of abrasive grains used for resin fiber discs:
Alumina is the most familiar abrasive grain and delivers excellent cut rates and sturdiness. This Aluminum Oxide Resin Fiber Disc is a popular and commonly used abrasive grain that tends to lower the user's initial cost.
There are three fiber discs contains AO abrasive grain:
There are three fiber discs using zirconium as abrasive grain.
Ceramic grain's maximum productivity and performance are tough to beat. Ceramic grain easily removes material and is the right choice for users who want to urge work done faster. The unique structure of ceramic grain, with significantly more fracture points, allows for more cutting power. Because of its self-sharpening nature, ceramic features fast stock removal, less friction, and cooler grinding. Ceramic Resin Fiber Discs makes ceramic ideal to be used on heat-sensitive materials and high-tensile alloys, also as steel.
Five fiber discs are utilizing ceramic as abrasive grain:
Silicon carbide features a unique grain structure; its abrasive grain can cut very quickly due to the sliver the shape of the grain. While relatively fragile, this structure makes it ideal to aggressively grind concrete, marble, granite, and other stonework. It performs alright on tough metals (cast iron, carbide, etc.) and titanium.
