Ernst Deburring Machines

Ernst deburring machine

ERNST sheet metal finishing machines feature all the components required to obtain desired finishing results. These components can be flexibly arranged to create the broadest product line offered in the industry. By choosing the desired features, the user is enabled to unite all the functionality he wants to utilize in one machine.

Machines are available both for wet and dry finishing. The most commonly applied units are the EM 5/N Wet Deburring System and the EG 3/M Dry Deburring System. The EG 3/M features the most powerful deburring capability for heavy burrs and slag aimed at flame and plasma cutting operations. The entire wet line of ERNST machines has astonishing processing capabilities, such as total deburring of vinyl, galvanized and aluminized coated materials or parts with up forms and distorted parts. The wet machines can be configured to grain, polish and remove oxide layers from laser cut edges for subsequent painting operations.

Thanks to the highly elastic surface of the grinding drum, it moulds itself around the edges of every opening of the work piece.

Oscillation of the drum ensures the optimal removal of burr and slag no matter which direction the edge points.

As you can see in the picture, the material is mainly removed precisely around the edges of a part of any complexity. This “magic” results in superior removal of the burr while at the same time reducing the amount of abrasive consumed. Note the even rounding of the edge in the picture.

Additional rounding is achieved by applying steel brushes or even more so by applying abrasive brushes. For possible combinations of finishing media see the list below of machine configurations both wet and dry.

Due to the softness of the Ernst Deburring drum’s matrix, thickness and distortion tolerances are easily accommodated, resulting in considerable gains in quality of the work piece and consumable savings. Even if the deburring machine is not used continuously it will deliver great return on investment.

Laser-Oxide Removal Machines

Lissmac Steel Brushing Machine Center | Deburring | Laser Oxide Removal System

Laser cutting in many ways has become the process of choice to flexibly manufacture a wide variety of geometries and materials in sheet metal fabricating. One of the inherent problems presented by laser cutting with oxygen though has always been the brittle oxide layer on the surface of the edges. Neither coatings, be it epoxies, powder or galvanic surfaces are properly bonded to these surfaces. Already small impacts lead to detachment of the coating in relatively large areas leading to corrosion and further coating deterioration.
Further laser cutting typically creates parts with great straight edges which are rather sharp, increasing the risk of injury.
To counter the shortcomings of laser cutting and to make the laser process ever more efficient, LISSMAC developed a brushing system specifically dedicated to Oxide Removal –
the Steel Brushing Machining centers “SBM”.

.Kuhlmeyer Deburring Systems - removal of "burrs" caused by the process of cutting sheet metal

Kuhlmeyer Deburring Systems - ZBS Series

Kyhlmeyer ZBS Series

Products And Key features Of The Kuhlmeyer Deburring Systems:

The most commonly sold machine is the simple but very efficient ZBS series grinder, featuring a twin belt to grind and finish each surface of a part in one setup. The ZBS requires certain practice and hand skills. Still the obtainable finishes even for an untrained worker are far superior in quality and productivity to hand finishing.


Especially well suited for applications in stainless steel and aluminum, parts of almost any shape can be finished to the surface appearance your customer desires. Parts can be held with a multitude of fixtures and supports into a stable and ergonomic position.

Kuhlmeyer Grinders


Either hand pads or the integrated pressure pads on a slide are used to apply defined pressure on to the part. The pressure pads are moved in an X direction while the part on the table or in the fixture moves in the Y direction. A motorized traverse is available for larger work pieces.

The machines feature long belts allowing the operator to bend them flexibly around the edges of the part. Precision engineered rolls guide the abrasive securely over three points, to give the operator maximum and safe access to the working area. The tension of each belt is pneumatically controlled and infinitely adjustable.

These Deburring Machines are available in various sizes and the accessories have to be selected according to the specific application of each customer. Please review the information below to find the best Kuhlmeyer Deburring Machine that will meet your requirements.
