The spiral brush coils can be wound up closed to or they can be distanced. The fill density or thickness of the brushing surface is comparable to the winding pitch or they can also be coils that are wound onto the body.
Electric-welded Spirals
Electric-welded Spirals are spiral brushes wound up closed, welded at their inside in order to realize a single cylindrical module. Thus it is possible to assembly more modules in order to obtain the length requested; moreover modules become easily interchangeable. Available with different diameters, filaments and trim length.
Static and Dynamic Balancing of the Spiral Brushes
The Dynamic balancing of the brushes it is indispensable to improve the performance the surfacesal treatment and to avoid stress to the brushing machine.
it is recommended to perform dynamic balancing for all brushes mounted onto an arbor and get exploited at high rotating speed. SIT can realize the dynamic balancing and issue the relative certificate
