Hard Density Abrasive Wheel Removes Challenging Burrs with Precision and Imparts a Fine Polish The Standard Abrasives™ Aluminum Oxide 900 Series Unitized Wheel is offered in two grades of aluminum oxide (A/O) mineral: coarse or medium. The combination of extra hard density and coarse mineral enables this wheel to withstand high-pressure applications and cut with force, making it suitable for heavy-duty deburring, cleaning, blending, and finishing.
Use a Standard Abrasives™ 900 Series A/O Unitized Wheel for removal of heavy flash and parting lines, deburring sharp edges, removal of coarse coated abrasives grind lines and removal of heavy machine tool marks. When it comes to blending, trust this wheel to blend pits in cast parts, refine surfaces on high nickel alloys and blend machined surfaces where wheel rigidity is necessary.
Compatible with a Variety of Tools Unitized wheels are typically used on a die grinder. A benefit of unitized wheels is that they are bi-directional and can be mounted on a tool or pedestal grinder without regard to the direction of the spindle rotation. This means the Standard Abrasives™ Unitized Wheel can be used with a variety of tools, and regardless of which way the workpiece is fed through the machine, the wheel will be able to respond, giving operators more flexibility. The stiffness of the unitized construction enables operators to use thinner wheels to access awkward angles with grinding tools.
Series 900 wheels comes in a range of diameters from 1-6" and requires a unitized wheel mandrel (sold separately) for attachment to the tool. Quick change wheels are also available (sold separately).
Get high performance and
durability in a variety of
cleaning, deburring, finishing
and polishing applications. Standard Abrasives™ Unitized Wheels are a great match for tough deburring, cleaning, blending and finishing applications. They come in a broad range of densities and grades to suit different metals, the degree of aggressiveness required, shape of the part, and desired finish. Although used for some of the same tasks as Standard Abrasives™ Buff and Blend products, they are designed with a far stronger and denser construction to support more aggressive applications and accomplish material removal more rapidly. Even though unitized wheels are much stiffer products, the non-woven nylon fibers of the wheel maintain the advantage of responding to surface irregularities while preserving the geometry of the piece, and produce a consistent finish.
Unitized wheels are created by starting with layers of open web material that combines non-woven fiber strands and abrasive mineral with a tough resin bond. These layers of web are then cured and compressed together. By fusing layers of open web, the abrasive gains more toughness and durability, so it can withstand repeated wear.
Ultimately, the wheel's durability is what makes it such a good match for edges. Regardless of the diameter or thickness of the wheel, it maintains its structural integrity to remain a stiff and long-lasting abrasive even under high pressure. Additionally, as the layers wear, the wheel can be dressed to maintain its shape.
