Processes

  • Deburring
    The deburring process is necessary to remove the flaws from the edges of metal workpieces, especially burrs and sharp edges left by previous machining processes.
    Rubber-clad steel sanding rollers are used.

  • Edge trimming
    After deburring, in some cases edges require trimming. This operation removes the sharp edge left by previous machining processes and leaves a smooth, rounded edge.
    Rounding is also useful on the sharp edges of any holes or pockets within the workpiece.

  • Buffing/finishing
    Once the processes required to improve the piece’s geometry and remove sharp edges have been completed, the next stage is to improve the level of surface finishing using abrasive belts or buffing rollers.

The deburring process is necessary to remove the flaws from the edges of metal workpieces, especially burrs and sharp edges left by previous machining processes.
Rubber-clad steel sanding rollers are used.

For effective material removal, Viet offers a range of rollers with extra-large cams to take belts of various thicknesses and high/strength, oil-resistant, flame retardant rubber linings to guarantee impeccable processing and surface flatness.
For processing only on the burr and thus on the perimeter of the workpiece, Viet also offers the electronic sectional pad unit.

After deburring, in some cases edges require trimming. This operation removes the sharp edge left by previous machining processes and leaves a smooth, rounded edge.
Rounding is also useful on the sharp edges of any holes or pockets within the workpiece.

This process is always performed with flexible abrasive bristles fitted on vertical rotary brushes. For edge rounding, Viet offers the option of installing the SpinBrush and Vspin units inside sanders. These units consist of an oscillating frame fitted with discs with abrasive or steel inserts.

High speed rotation of the discs and oscillation of the entire unit beam rounds the sharp edges of profiles and removes any waste or traces of oxide on the side of the workpiece. Use of the most suitable tool is simple and immediate thanks to the quick change system installed on the SpinBrush and Vspin units.

Once the processes required to improve the piece’s geometry and remove sharp edges have been completed, the next stage is to improve the level of surface finishing using abrasive belts or buffing rollers.

The combination of soft contact rollers (40-24 Shores) with fine grain abrasive belts improves pieces’ surface quality, reducing roughness and giving flat sections a flawless appearance.

The abrasive fabric buffing rollers smooth the surface already sanded by the abrasive belts, reducing the depth of the scratches created.
The buffing roller is also available with transverse oscillating motion, for more effective smoothing of the scratches left by the rotation.
