Lissmac Deburring Machines | An overview

Who are Lissmac?

Lissmac are a German based company with four business divisions; construction technology, MT-Handling, Plant Engineering and Metal Processing. Lissmac offer a variation of machines depending on your specification; they offer two sided processing in a single pass, two sided small parts processing, one side wet operation and one side dry operation.

What tools do Lissmac offer on their metal processing machines?

The machines use a variation of tools, these include; brushing, sanding, grinding, deslagging and edge rounding.

Machine Tools:

Brushing – Oxide Removal 

brushing

Effective oxide layer removal on all cut surfaces of inside and outside contours. Special brushes on a power belt work across the cut surface and precisely remove the oxide layer.

Removes rust, scale and dirt clearly improves the surface quality.

Sanding – Edge Rounding

sandingFlexible grinding modules on a power belt specifically process sharp cut edges of workpieces. Secondary burrs are hereby also removed effectively. The grinding modules can be fitted with suitable grinding media to match application or material of the workpiece.

Grinding – Deburring 

Deburring of thin metal sheets:

A grinding belt processes the surface of the material. Burrs, surface spatter that can occur during punching or laser cutting and fine plasma burrs are removed specifically. While a slight surface cut is being developed, the actual grinding process focuses on the cut edge.

Deburring of thick metal sheets:

Two grinding belts are used due to the stronger burr resulting from plasma and gas cutting. The surface grinding focuses on the cut edges of the workpiece.

Deslagging – Slag Removal

deslagging

Power pins installed on a power belt have a specific effect on the workpiece edge. The slag can thus be removed simply and effectively. Mechanical chipping achieves clear savings in tool costs. Efficient processing is achieved as time consuming and costly grinding processes are omitted.

Edge Rounding 

All workpieceedge rounding edges, on outer and inner contours, are simultaneously rounded by two rotating and flexible abrasive lamella rollers. At the same time, secondary burrs are effectively removed, whereby galvanised surfaces or protection foils are not damaged.


 

Based on your specific needs there is a metal processing system for everyone. Each machine offers different benefits. Please see below the different variations.

SBM-XS

Capture

Deburring and uniform edge rounding on all sides of parts of small parts – dimensions up to 25 x 25 x 1mm (magnetic table) or 45 x 45 x 1mm (vacuum table) up to a maxiumum of 200 x 200 x 15mm, both on outer and inner contours, in a single pass.

SBM- M SERIES 

The M series can be equipped with two aggregates on the top and the

Capture2bottom and individually with matching tools. Tools are adjusted electrically. Upper and lower aggregates can be operated and adjusted independently. The transverse to the to the feed direction moving workpiece ensures ideal tool utilisation ratio. Sheet thicknesses feed and tool status can be adjusted by a joystick and further control elements respectively. The sheet thickness is clearly indicated on a display.

What are deburring machines?

Deburring machines are used in the metal processing industry. They are used to remove burr left over after the machining process – either from punching, laser cutting, plasma cutting or drilling.

Why do i need them?

In order to keep a clean, smooth finish to your material. Deburring machines are a necessity. This is conducted through a mechanical process which grinds the burr off the metal or rolls the edge of a dangerous slit. Rolled mechanical deburring was first developed in the 1960s by Walter W. Gauer from Gauer Metal Product, Inc. as a means to speed up the process of hand deburring strips of metal that were used in battery racks.

How do they do it? 

Each machine varies in the way it removes burrs. Below shows the different variety of machinery Lissmac has to offer for all your deburring needs.

Both sides – One work step…

For small parts, Lissmac offers the XS series – it sets the benchmark for small part sheet metal processing. Through highly effective two-sided deburring and uniform edge rounding of punched, laser and fine plasma cut workpieces using only one work process. Unlike other grinding machines, the SBM-XS wins over customers with its highly efficient form of processing with up to 60% work savings.

SBM-M,L,XL Series

The SBM M series of machines from Lissmac – include a variation of benefits. This includes oxide removal of laser cut sheet metal on both sides in one single pass, deburring and edge rounding and slag removal of plasma and oxy fuel cut parts on both sides in one single pass.
