ATB Abrasive Nylon Filaments
Abrasive Media Options
 | Silicon Carbide is characterized by a sharp jagged structure, and is the most popular grain choice because of its cost effective, efficient properties. (Color: gray/black. Hardness = 13 [MHOS Scale], Density = 3.25) |
 | Aluminum Oxide is characterized by a rounded structure and produces a finer finish and prevents discoloration on certain alloys such as titanium, aluminum and stainless steel. (Color: tan/brown. Hardness = 12 [MHOS Scale], Density = 3.99) |
 | Poly Crystalline Diamond (PCD) is characterized by a jagged structure. PCD is used to edge hone and radius super hard materials such as CBN and ceramics. (Hardness = 15 [MHOS scale]) |
Filament Geometry Options
ATB abrasive tools feature three different filament geometries: round crimped, round straight and rectangular.
Round Abrasive Nylon Filaments are impregnated with either Silicon Carbide or Aluminum Oxide grit. Grit sizes vary from coarse to very fine. This style is available in crimped or uncrimped form, and is also made in Alumina Silicate and Polycrystalline Diamond super abrasives. •For general use
•Provides point contact - light to medium application technology
•Fine grit sizes are able to radius small corners
•Uncrimped filaments generate twice the abrasive contact on work surface
•Increased flexibility to conform to irregular surfaces | 
|
Abrasive Nylon Rectangular Filaments are impregnated with either Silicon Carbide or Aluminum Oxide and are offered in grit sizes ranging from coarse to fine. • For high performance work
• Line contact - heavy duty application technology
• Applies approximately 18 times more abrasive on work surface
• Ideal on applications requiring more surface compliance without sacrificing the amount of abrasive in contact with the work surface
• Larger cross section allows the filament to be more rigid and aggressive
• Shorter cycle times
• Ability to remove micro chips and materials
• Excellent performance at lower rotational speeds
• Superior draw file grinding action using sides of extra long filaments | 
|
Filament and Grit Size Options
Smaller filaments with smaller grit produce a finer finish and offer longer life. Larger filaments are more rigid and apply larger abrasive grit to the work piece with greater force and increased aggression. Grit sizes are available from 46 – 1000.
Crimped filaments offer better part conformability. Rectangular filaments offer higher aggression.
