The SBM-G/S 1000 sheet and plate deburring machine from Lissmac has been installed at a wood-processing machine specialist to enhance productivity and offer a cleaner working environment.

The machine deburrs and rounds cut edges of thick steel plates on both sides simultaneously in one pass.

Production, which begins with cutting the steel plates, is set up to handle 12m-long components.

The plates, which are up to 100mm- or sometimes 160mm-thick, are then cut according to the design specifications.

The parts are sawn, flame or plasma cut.

After cutting, the sharp edges and the burrs, which can be up to 5mm high, must be removed.

This was implemented with angle grinders until the Lissmac deburring machine SBM-G/S was installed.

Sparks, dust, dirt, noise and unhealthy body postures characterised the old working method.

The Lissmac model SBM-G/S 1000 has a maximum working width of 1,000mm.

It deburrs and rounds the cut edges of sheet-metal plates with a maximum thickness of 120mm and burrs up to 5mm in height.

Independent of their shape, several plates of the same material thickness can be placed side-by-side on the conveyor.

The SBM-G/S 1000 has several grinding heads.

The parts are guided through the machine by pressure rollers.

After pre-grinding, which smoothes the cur edges, more pressure rollers guide the plates to the second set of grinding heads where corners are rounded.

Plate thickness setting is motorised.

With the frequency controlled feed, the feed speed can be infinitely adjusted.

As the feed speed influences deburring quality and the degree of rounding, the optimal speed is approximately 2m/min.

Before the Lissmac deburring machine was commissioned, the wood-processing machine specialist carried out edge processing with angle grinders.

The angle grinder is still used when parts thicker than 120mm are being deburred, however, the majority of the cut plates are less than the 120mm limit.

The deburring machine now accomplishes what four employees in two shifts managed to complete.

The machine operator has sufficient time available to also operate the shot-blasting system and to monitor material handling.
