Deburring of the side of a thermal dissipation part used in an auto radio
Aluminum Extrusion Before Cutting Process
This small aluminum part has sharp edges all around the sides. This was due to the aluminum cutting process to create it.
Giving this, the customer needed to remove sharp edges and small burrs from this aluminum extrusion part.
NS DM1100 C edge rounding standard machine for edge rounding of metal sheets and small parts was the solution found for the edge problem. Due to the shape of the aluminum part it was not possible to put it in a straight position. In combination with guides on the top side of the conveyor table was enough to guarantee that the parts would be in the vertical position.

The cross belts system combining two belts running in opposite directions are enough to deburr and remove sharp edges from this small part. The final result is a smooth edge due to the edge rounding process.
After and Before Process of Deburring Aluminum Extrusion
In combination with a special parts return system, the operator fed the parts in the table and then passes through the return system. After the inspection, the operator flips the part in order to deburr the other side. The parts return system enables the machine to operated with just one worker instead of several.

DM660 ZPK is a deburring machine for sheet metal and parts cut by punching, shearing, laser or plasma.
DM660 ZPK features an integrated vacuum table and a 3 movement system of the brushing head, assuring a high consistency. It is possible to work parts up to 660mm width and some as small as 50x50mm.
This machine can perform rounding on small holes, bended plates and create big radius up to 2mm.
By blocking the rotation head this machine can be used for surface finishing in a configuration of wide belt and double parallel brush.
On DM660 ZPK it is easy to interchange brushes, so it is possible to achieve rounded edges free from burrs or sharp corners but also to clean oxide layer.
When operating with steel planetary brushes DM660 ZPK removes efficiently the oxide layer on interior and exterior contours of laser-cut steel sheets.
DM660 ZPK cleans oxide layer in 2 step operation on parts from 4mm up to 25mm thick.
Preparing steel cut parts for coating by removing oxide layer will improve the ability of the parts to be coated. Powder coating or wet paint adheres well to the oxide layer. However, when the surface is damaged or subject to impacts the oxide layer can detach from the material, limiting the lifetime of the coating.
DM660 ZPK performs oxide removal with flexible and efficient wire brushes, leaving the parts oxide free and ready for further coatings.
See the demonstration video below of this oxide removal machine where steel parts are brushed from oxide.
DM edge rounding machines are available with deburring station before the cross belts.
The soft contact roller Ø240mm can grind away burrs from laser and plasma, while the cross belts will remove sharp edges, rounding them with extreme efficiency. These machines can actually work parts down to 50x50mm.
The stations are independent. This makes possible the operation only for edges rounding (without abrasive belt) and only for parts finishing in a second step after deburring and edges rounding.
These models count with fixed working height, motorized control of thickness and cross belt pressure/wear.
The cross belts are positioned at 35º, which permits the use of the full width of conveyor belt. Parts will not be placed at an angle as it is done with DM1100 C. More, we can have a straight finishing after edges rounding if a 3rd station is required (abrasive belt or brush unit).
This machine is available in 2 sizes: working capacities of 660mm and 1100mm (DM660 ZC and DM1100 ZC).
Check the demonstration video below where a stainless steel laser cut part is deburred and edge rounded. See also more examples at www.nsmaquinas.com
DM660 ZPK is a deburring and edge rounding machine for sheet metal and parts cut by punching, shearing, laser or plasma.
Removing burrs and creating round edges using planetary brushes technology is possible on parts up to 660mm width and on some as small as 50x50mm.
Inside and outside contours of stainless steel, steel and aluminium parts cut by laser or other thermal processes are burrs cleaned from the total surface.

DM660 ZPK features now an integrated vacuum table, a re-designed conveyor belt with higher holes density for smaller parts deburring and a 3 movement system of the rounding head, assuring a higher consistency of the parts processed.
Metal sheet deburring, laser cut parts edge rounding, removing burrs and sharp corners and creating soft edges are operations easy to achievable with DM660 ZPK abrasive deburring machine and demonstrated on the video below.
