Selection of the right type of brush - JAZ Zubiaurre

The power tool speed influences the performance of the brush and the safety of the operador. If load speed marked on the power tool is higher than the brush MAXIMUM RPM, do not mount the brush. Maximum RPM are indicated on brush side plates and shall never be exceeded.

MAXIMUM RPM are the maximum RPM at which the brush could be run with no work applied (spinning free). It is merely a safety indication for the user, not the recommended operating speed.

Steel brushes are not always the right solution. Depending on the metal part to be cleaned, you can also use synthetic fibers (nylon, polypropylene, pekalon, etc.) for cleaning. For example, a plastic conveyor belt cannot be cleaned with wire brushes, but you can do it with synthetic fiber brushes.

With our main focus of finishing surfaces with the use power and hand brushes, we specialize in fill materials that can be used in brushes. With brushes it is not possible to achieve finishing that is possible with other materials such as scotch brite, abrasive sponges, etc …

In the market, abrasive nylon, aluminum oxide, diamond, etc. fibers are available. They are the most widely used abrasives in brushes. With this type of brushes, fine burrs and improvements in surface finishing are achieved. These are synthetic fiber filaments impregnated in the different types of abrasive mentioned above. The most widely used fiber is Abrasive Nylon.

Wood has different characteristics than other materials. The end user is the one who knows the finishing type he is looking for and that can change the criteria when selecting brushes. They are generally carbon steel brushes along with abrasive nylon brushes. The choice of wire thickness will depend on the type of wood (hard or soft), as well as the grain of the abrasive nylon.

Work efficiency increases as a brush diameter increases. To calculate the biggest possible diameter, it is necessary to consider the maximum RPM of the power tool or machine being used (i.e. for an electric tool with maximum RPM of 6,000, the brush should not exceed 175 mm diameter).

A shorter trim length provides a more aggressive brushing action, whereas flexibility to adapt to irregular or uneven surfaces increases as trim length increases. In contrast to abrasives and cutting tools, wire brushes do not remove the base material of a treated surface. Herein, brushes serve as an essential tool for a wide range of industrial processes.

Multithreads and Adapters: The exclusive and patented JAZ threaded nut provides for a number of advantages: Easier tightening into machines. Higher resistance of the brush against possible deformation. The multithread option allows the use of one brush on machines with different types of spindle: R88 threaded nut: fits both 5/8-11” and M14-2 machines. R77 threaded nut: fits both M10x1,25 and M10x1,5.

The purpose of these innovations is to help distributors better manage the line by reducing the number of SKU-s or items and improve their level of service to their customers and end users.
