Industrial Brush Repair Services Information

Brush repair services refurbish, clean, mend, or recondition used industrial brushes. This includes refilling brushes with new bristles as well as developing and repairing brush design problems. Reusing cores and bases saves materials, labor, and energy, often making brush repair more cost effective than replacement. Types of serviced brushes include abrasive brushes, rotary brushes, strip brushes, power brushes, and utility brushes.

Brush Wear and Damage

Brushes wear, lose bristles or wires, and become loaded with removed dirt, fibers and debris. The tips of the bristlesFoundry brush adjustment via SIT Brush or brush filaments become dull over time. In abrasive brushes, the abrasive grains will eventually wear forming wear flats, fracturing or dislodging from the filaments. Bristles, wires and abrasive filaments can also be pulled out from brushes during use. At high speeds, rotary brushes can eject their bristles, abrasive filaments or wires especially if speeds higher than the rated speed are used or if the wires are not held tightly in the brush. In addition to wear and loss of bristles, brushes can load with the soils, dirt, rust, corrosion by-products, wood fibers, oily or grease residues, stripped paint or coating chips, gunk or gummy deposits or other material cleaned or removed from a surface during brushing. After brushes wear, lose bristles or wires, and/or load with debris; the operators tend to apply more pressure to the brush during brushing to continue to clean, deburr, remove material or improve the surface finish. The pressure applied during brushing can cause the wires or bristles to bend over, flatten or produce a frayed or “haywire” condition, which further reduces the capability of the brush.

The engineer or end user should assess the cost benefits of repairing versus replacing a brush. A small, low cost hand brush is not likely worth sending out for repair. Larger, production rotary brushes might be worth refurbishing depending on the type or damage.

Types

Several different brush repair processes or repair steps can be taken to improve brush effectiveness before a completely new replacement brush must be purchased.

Brush Cleaning / Deloading – Brush cleaning or deloading removes the soils, dirt, rust, corrosion by-products, Deburring brushes via SIT Brushwood fibers, oil or grease, stripped paint or coating chips, gunk or gummy deposits or other cleaning or finishing residue. Brush can be cleaned with a comb or the combing action of another brush. Cleaning agents and solvent can also be used to clean brushes, but the cleaners or solvents should not attack the brush ferrules, core or base.

Bristle / Wire Straightening – Brush filaments, wires or bristles can be straightened out to some extent with a comb or the combing action of another brush.

Bristle / Wire Replacement – For extensive brush damage where many bristles or wires are missing and/or many of the remaining bristle are bent over or flattened, the best course of action might be to replace the bristles, wires or filaments.

Core / Base Repair – In some case the core or base hold the bristles gets chipped or damaged during brushing operations. If the damage impacts the brushing performance or safety, then the core, base or body should be repaired.

Handle / Grip Repair– The handle or grip of a brush sometimes loosens or is damaged during use. The handle grip should be repaired to allow a secure and safe holding of the brush by the operator or end user.
