Cup brushes are generally used to remove scale, rust, and paint, as for deburring and polishing. Different duty levels and fill materials are available to suit the right tasks in surface preparation, burr removal, and finishing operations.
Wire cup brushes are cup-shaped tools made from steel or chrome steel filaments. Machine part manufacturers use them for surface preparation, deburring, and surface finishing.
Its primary applications include removing rust, paint and welding scale, metal cleaning, and edge blending.
There are different types of cup brush sizes available, but tool selection isn't almost filament material, which may be the workpiece's function. Brush diameter, wire size, and trim length are also essential to consider while choosing the right brush.
Cup brushes are available within the following duty levels and sizes:
Standard Duty Cup Brushes: These brushes are designed for removing scale, rust, paint, and other surface preparation, including deburring and polishing. A larger format allows coverage of enormous surface areas. Standard-fill materials include steel, chrome steel, brass, and bronze wire, plus abrasive nylon, nylon, and treated or untreated Tampico fiber. A 5/8″-11 threaded arbor hole is standard. Other fill materials and arbor hole sizes are available in a particular order. Recommended maximum safe free speed ranges from 6,000 rpm to 9,000 rpm. Diameters include 3", 4″, 5″, and 6″.
Wire brushes are a superb choice for removing rust and oxidations, paint, slag, weld splatter, and other unwanted surface contaminants with angle grinders, bench grinders, or drills. But with numerous options available, how does one choose the proper wire brush for the job?
Here are three key factors to consider:
Wire brushes are available in steel, chrome steel, and brass. Brass is relatively versatile and may be used on almost any project, while steel and chrome steel are best paired with specific material types. Selecting the proper one is as easy as matching the wire type to the fabric in your application.
A good rule of thumb to follow would be to pick very fine wire for light-duty jobs and medium to coarse wire for heavy-duty jobs.
3. The filament configuration
Wire cup brush, wheel, and end brushes accompany three options for filament configurations, and every one has its benefits.
