Designed for the deburring and edge rounding of parts cut by laser, flame, plasma and water-jet — as well as the finishing of punched and machined parts — the Timesavers 42WRB from Christchurch-based Ellesco Ltd (www.ellesco.co.uk) can undertake the pre-grinding of heavy burrs and the final surface finishing of components in one pass.

The W element in the WRB is a wide-belt abrasive head; this is the first contact point for parts passing through the component conveyor and is primarily for removing heavy burrs on plasma-cut, laser-cut and punched parts immediately after cutting.

For customers needing to achieve a specified level of surface finish or grain, the machine can be fitted with a secondary abrasive head; this is the final stage in the finishing process.

The RB element is the rotary brush. There are eight brushes on a rotating carousel; each brush has its own rotating axis, with four brushes working in a clockwise direction and
the other four operating counter-clockwise.

The abrasive strands on the eight brushes jointly process the entire surface and all edges of a part to provide an even radius on all corners.

The level of radius is determined by the conveyor speed, the brush rotation speed, the rotation speed of the carousel and the height setting, which adjusts the level of pressure applied by the brushes. All these are programmable, and the process is automatic.

If a non-specific finish is required, in instances where a multitude of various parts are continuously run through the machine, the operator can over-ride the automated parameters. Parts from 50 to 1,350mm wide and up to 100mm thick can be processed.
