Our metal working machines are designed for a variety of applications, including removing burr or slag, precision grinding, oxide removal, rounding edges and polishing metal products.

Apex machines can support up to four working heads in order to achieve optimal results. With a combination of abrasive belts, oscillating discs, and rotating brushes, it is possible to grind, remove burr or slag, round edges and/or polish your product in a single pass.

Whether you are processing stainless steel, mild steel, aluminum, copper, brass, titanium, or other ferrous or non-ferrous material, we have a machine to meet your needs.

Metal Applications

Deburring

The deburring process involves removing the rough edges from material that has been created from machining operations such as such as laser cutting, plasma cutting, flame cutting, shearing, punching, and drilling.

There is no universal definition of deburring – some consider a part deburred if the vertical burrs are removed; some don’t consider a part deburred until all outside and inside edges have been processed.

Deburring small parts requires special consideration in the deburring process. Apex offers a unique design that allows both small and large parts to run on the same machine. A special style conveyor belt that securely holds the small parts, a scuffing device for cleaning the conveyor belt and two 4” dust ports for cleaning debris from the belt make this a great solution for those shops needs to run small parts as small as 3” x 3”.

Edge Rounding or Edge Radiusing

Rounding the edges of a deburred part involves removing the vertical burrs, scallops, or nibble marks on the edges and holes of the processed material. This is also referred to as edge radiusing. Oscillating discs equipped with abrasive sanding strips are used to uniformly break the edges of deburred parts. An edge radius of up to 2 mm may be achieved.

Heavy Slag Removal

Slag is the molten metal that remains after a part has been flame cut or cut by a plasma cutting machine. Our slag grinding machines are designed to not only remove the slag or dross, but also to remove any mill scale left on the part. They are equipped with a hard durometer contact drum, a course abrasive sanding belt, and high horse-power motors to aggressively grind heavy steel plates.

Precision Grinding

Precision grinding is performed by a wide belt that grinds the thickness of a part to achieve a desired fixed thickness. Apex grinding machines are designed with a high tolerance level, allowing for precision up to 0.02 mm.

Polishing and Finishing

Finishing and polishing metal is the process of refining the surface to a finer finish by using various grits of abrasives. Polishing can be obtained using either a wet or dry process. The wet process is typically the preferred method for getting the best results when polishing and finishing materials. 

Graining

Graining of metal is the process of taking a raw or rough piece of ferrous or non-ferrous metal and applying a fine grain finish to establish an aesthetically uniform grain finish. This finish can be altered using different grits of abrasives.
