Wire Brush Operating Hints

PCI Blue Catalog Back Cover-copy_edited-1.jpg

Wire brushes from United Global Supply are pre-sharpened as part of the manufacturing process, to insure proper balance. The arrows on the hub indicate the direction of rotation when the brush is first installed . After initial period of use, reversing the brush on the shaft, periodically, will tend to resharpen the tips , providing faster cutting and increase the life of the brush.

When resharpening a United Global wire brush - reverse the direction of rotation, using a United Global No. 78 Sharpening Stone, apply light pressure, holding the stone flat against the brush surface. Light pressure will insure that the wire tips are not overheated, causing the temper of the wire to be removed and making it difficult to maintain sharp cutting points. 

USE OF FLANGES

The use of graduated flanges is recommended for maximum brush life. Use the largest flange possible to reduce excessive flexing of the wires., reducing flange diameters as the brush wears. The rule of thumb is to have a maximum wire extension beyond the flange of 3/8" and to change to a smaller flange when 1/8" of wire is showing. United Global has a complete line of wire brush flanges. They maybe purchased in individual sets of two or complete graduated sets to fit any machine. 

BRUSHING PRESSURE

Remember - The tips of a wire brush do the work. Operate the brush with the lightest pressure so, only the tips of the wire come in contact with the surface to be abraded. 

If heavier pressures are used, the wires will be over flexed, resulting in a wiping action and, if this is continued, the life of the brush will be severely shortened due to wire fatigue from the wire flexing. 

Apply the surface to be roughed to the face of the brushing such a way that as much of the brush face, as possible, is in full contact with the work surface. Applying the work to the side or edge of the brush will result in wire breakage and shortened brush life. 

WIRE BRUSH SAFETY RULES 

Read and observe the "Power Brush Safety Requirements" insert that is packed with each United Global Supply wire brush. 

ALWAYS USE REQUIRED EYE PROTECTION WHEN USING WIRE BRUSHES.
