Extrusion Part Before Deburring
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.

Plasma Parts - Deburring and Edge Rounding - DM660 ZC

One of the most known cutting processes for metal sheets is plasma cutting. This process uses a high velocity jet of ionized gas heating the workpiece and cutting by melting the material. Despite being a very economical and fast process, for thick metal sheets it has a big downside: big burrs.

Since the metal is melted, the top of the part has a clean cut but on the other hand the bottom remain with the burrs of the melted material. These burrs are, in most cases, undesired because changes the piece sizes and specifications. In order to be used on the final process, companies need to remove the burrs by implementing a deburring and edge rounding solution.

NS Máquinas developed the DM1100 ZC - Deburring and Edge Rounding Machine specially to remove medium and big burrs and perform the edge rounding in the same process. In order to do this, this machine, includes a deburring station with an abrasive belt and a large contact roller. Also, it has a double cross belt station with two belts running in opposite directions enabling the edge rounding.

The following sample is an example of the machine capacity:

Before and after deburring and edge rounding process

This piece has severe burrs on the bottom part and the costumer needed not only to remove it as well edge round and finishes the piece. After the deburring station the burrs were totally removed from the bottom surface. Also, giving the flexible cross belt abrasive blocks the edges of the part were soft and round.

The right edge: NEW 1350mm width joins the 660mm and the 1100mm


How it works

DM machines with ZC configuration, combine deburring and strong edge rounding in one single machine, processing small and large parts cut mainly on laser and plasma.

The large diameter contact roller deburrs efficiently small and medium size burrs while the 2 counter rotating abrasive cross belts leave a soft edge both on the internal and external contours of the parts.

Now, DM ZC machines are available in 3 working widths (660, 1100 and 1350mm) being able to better suit each company production range. Since the 2 stations have an independent construction, these machines enable the work with 1 station only as well. Making a soft edge on burr free laser or punched cut parts or supplying a linear finish on metal sheets is possible with any of these versions.

Small parts down to 50x50mm deburring and edge rounding is one of the big strengths of this machine. More, this line of equipment can be fitted with parts return systems and support roller tables increasing productivity both on small and large parts processing (available from NS Máquinas). The integration with these devices is made easier due to the fixed conveyor belt working height design.

DM660 ZPK: Deburring, Edge Rounding, Finishing and Oxide Removal Machine

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.

Laser Metal Deburring and Edge Rounding Machine at Foekema

Foekema Plaatbewerking BV is a Dutch company specialized in metal sheet services and fabrication. The company which provides laser cutting, welding and engineering services has just purchased an innovative corner rounding machine from NS Máquinas.

DM1100 C stainless steel deburring machine
The need for a metal deburring machine was due to the increasing demand in the food industry, where customers like rounded and burr-free laser cut parts, both for hygienic reasons and also in order to eliminate the risk of injury with laser cut sharp edges. On the other hand customers demanded steel parts with rounded edges to assure better adhesion of powder coating and zinc layers. For these reasons Foekema decided to move on to the purchase of the NS Máquinas deburring and edge rounding machine DM1100C.

Mr.  Johan Foekema, managing director of the Dutch company, told us about his option. “After comparing different brands and models the NS Máquinas DM1100C was soon our best choice.”

“In contrast to other metal deburring machines DM1100C edge rounding machine may also process small parts, even dimensions of 25x25mm are feasible! This makes it possible to supply laser cut parts to our customers which are finished and edge rounded both on the outside and on the inside contours with the same surface finishing.  Many other companies tumble small parts which has necessarily a different look.”

One of the benefits that Mr. Foekema points is the fact that he can deburr steel and stainless steel parts with the same machine. DM1100 C has a simple and quick system for abrasives replacement. In less than 3 minutes the edge rounding abrasive cross belts can be replaced, being possible to interchange the abrasive tools for steel and for stainless steel. The manager points: “Both stainless steel and steel parts can be finished and deburred on the same machine. More it is a very easy to clean our metal deburring machine.”

DM1100 C stainless steel deburring machineDM1100C edge rounding machine can also deburr stainless steel laser cut parts with plastic foil, leaving the surface untouched. “Parts which were laser cut with film protection are not a problem. The film remains tight and the contours are rounded”.

The NS Máquinas metal deburring machine proves to be also the right choice for many steel parts. According to Mr. Foekema the DM1100 C is “ideal for parts that will be powder coated or galvanized, once with rounded corners and holes there is better adhesion.”

This metal sheet edge rounding and deburring machine has a maximum width of 1100mm and works up of 50mm thickness.

The DM1100C metal deburring machine has a cross belt edge rounding technology because the machine is equpped with two transverse belts. These cross belts have sanding blocks which consist of abrasive flaps with scotch brite. These abrasive tools are designed to provide the removal of the burr and edge rounding of the corners. At the same time the cross belts provide a nice finish, especially in stainless steel.

Regarding the investment on the NS metal deburring machine Foekema has no doubts and concludes “a relatively short operation time with low processing costs”.

DM1100 ZC: Deburring and Edge Rounding in One Machine

DM1100 ZC: Deburring and Edges Rounding Machine

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).
