Specifications and Procedures
When using machine-powered interior brushes, it is crucial to adhere to the maximum specified speed. Brushes should be clamped to a depth of at least 10 mm and inserted into the workpiece before rotation. They should rotate clockwise. The power requirement data provided are guidelines, and it is important to compare the idle speed of the angle grinder with the maximum speed specified for the brush.
Brush Selection and Optimization
Choosing the right brush involves considering the diameter, filling length, and wire diameter. For weak brush effects, increase the peripheral speed or use a brush with a shorter filling length or larger wire diameter. For strong effects, decrease the speed or use a brush with a longer filling length or smaller wire diameter. For wet applications, PA 6.12 is recommended due to its reduced water absorption.
Materials and Characteristics
Various wire materials are used in brushes, including steel, brass-coated steel, and stainless steel, each with specific properties like tensile strength and temperature resistance. Synthetic bristles and abrasive filaments are also used for specific applications, offering flexibility and abrasion resistance.
Brush Types and Applications
Knot wheel brushes are used for weld preparation and finishing, removing scale, rust, paint, and deburring edges. They are available in multiple rows for denser filling and can be customized for specific needs. Stainless steel brushes are identified by green side plates and are available in different wire materials.
Technical Data and Recommendations
Tables provide data on power requirements, recommended peripheral speeds, and conversions between millimeters and inches. The document also includes information on the physical properties of different wire materials and recommendations for specific applications, such as deburring and polishing.
