Thermal deburring isn’t new. Put your components in a sturdy box, add flammable gas and ignite. The principle is pretty basic in that any oxidisable burrs are simply burnt off, but the larger mass, which is the body of the component, is unaffected because it absorbs the heat.

That’s ok for iron, lumps of aluminium, and some plastics. But not for stainless, which by its nature is “inoxidisable”, nor for brass which absorbs the heat faster than it can be used to deburr, so higher temperatures and pressures need to be used to melt and vaporise burrs.

The downside of this simple process is the damage which can occur to components, the aggressive chemicals required in cleaning the resulting surfaces, and the shear size and cost of the thermal deburring machine and its associated cleaning plant.

SGM have addressed all three issues with their “Exploit” technology which Ellesco offers as part of its portfolio.

The SGM – Exploit:

• Operates at lower pressures resulting in less consumable cost, less likelihood of damage to components, less strain on the machine.
• Uses patented nano-surface-technology chemicals of mild acidity to clean up after the operation, and which in turn are easy to dispose of.
• Has computerised control and a cylindrical chamber (as opposed to the old-fashioned bell type) making the machinery 30 – 50% cheaper and more compact than comparable 1960’s technology (and up to 5 times quicker).
• After a mild degreasing and swarf removing pre-wash (part of the SGM-Exploit plant), components are stacked off-line in layers in the work baskets for precision deburring, or simply poured into the baskets for general deburring. The highly controllable, light gas pressures mean that even thin-walled, delicate pieces, and high thermal conductivity parts such as brass, can be processed. The cylindrical chamber results in a hydraulic locking stroke of a mere 20mm and the contents of the basket are equally processed from top and bottom, front and back, left and right.
• The (small) wash plant uses mild aqueous chemicals, surfactants, ultrasound, and steam to clean, wash and dry components.
•  And with an eye on the environment, the machinery exhaust system minimises oxide discharges, and the wash chemicals re-circulate with no discharge to the environment.

An old idea made fit for modern use. Send us some pieces and we’ll prove it.

Abrasive wide belt grinding machine for calibrating and finishing of Graphite and CFC material.

• HMI colour operation panel for simple setup
• Programable up to 999 programes
• Multicycle with automatic thickness compensation
• Stock removal up to 0,5 mm per cycle
• Tolerance after grinding up to 0,05 mm
• Working width up to 1350mm
• Workpiece thickness up to 250mm
• Throughfeed speed up to 10m/min

Belt change is quick and easy by quick release outboard support. Optimum life time of belts is obtained by the cooling effect of the serrations in the contact roller.

Airjet cleaning devices keep the Billy Roll free from excessive dust. The Billy Roll is equipped like the contact roller with a fine adjustment. The hinged top frame is firmly clamped by two quick release supports and ensures the highest precision without guide or spindle play.

The machine is supplied with all safety features like emergency stops, main motor disc brake, belt safety switches and finger sefety protection.

This bottom-, deburring, grinding and polishing machine increases production while maintaining constant quality. This machine gives multiple shift production capacity of magnetic laminations or sheet processing in throughfeed deburring or grinding.

First Head

Fixed grinding head with an aggressive 180 mm. dia. Drum of solid steel with a hard-rubberized plain face.

This hard plain faced drum hits and grinds away the high and hard melted down ‘slag’-burrs only. (It stays just free or is light rubbing on the surface of the parts).

Second Head

Fixed grinding head with a large 280 mm. dia. forgiving drum of special diamond serrated highly flexible rubber.

This drum is set 1 to 2 mm below the work piece surface line and it blends all edges (the grinding belt must be dull, ideally the used belt of the first grinding head).

Third Head

Steel wire brush, large 280 mm. dia. To smoothen (blend) the remaining sharp edges caused by the grinding belt.

Not only will this brush smoothen the edges of the deslagged part, but will also clean the parts.

Floating Table

Unique and simple floating feed bed. Easy to operate motorized automatic thickness setting with additional hand wheel for fine adjustments.

The pneumatic non-friction “tiger-ball” floating bed, automatically adjusts the differences in the parts thickness.

Always the correct grinding pressure for every size and/or weight of part, irrespective of thickness differences and ‘slag’ height.

The feed table floats independently to the grinding belt due to a 4 pneumatic ‘tiger-ball’ construction
