Belt & Disk Sanders

Belt and disc sanders for metalworking

A belt and disc sander is one of the fastest tools for deburring and for edge and surface grinding of metal. It combines two grinding methods in one machine and covers a broad range of tasks. KNUTH supplies robust machines for metal fabrication, structural steelwork, maintenance and technical training, including demanding mining and heavy engineering environments, from the compact workshop unit to versions with dust extraction.

Belt grinding and disc grinding: the difference

Both methods complement each other and can be combined on many machines:

• Belt grinding: the continuous sanding belt removes material evenly across larger surfaces. Ideal for flat stock, longer edges and preliminary or intermediate grinding.
• Disc grinding: the rotating disc offers a stable surface for precise results on edges, curves and radii.

Combining both methods in one machine increases versatility and shortens set-up times.

Typical applications

• Deburring after sawing, drilling or flame cutting
• Breaking and chamfering edges before welding or assembly
• Surface grinding on sheet metal and components
• Radius and contour grinding on bent and complex parts
• Surface finishing depending on the grit of the abrasive

Designs at KNUTH

Different designs suit different workshops and grinding tasks:

• Double grinder (bench grinder): the classic workshop machine with two grinding stations. Models with electronically variable speed match the cutting speed to the material.
• Combined belt and disc sander: sanding belt and disc in one unit, often with an adjustable work rest for repeatable angles.
• Version with dust extraction: keeps grinding dust out of the workshop and is therefore suited to continuous use and training.

You will find the exact equipment and dimensions of the currently available machines in the product cards above.

Which materials are suitable?

Belt and disc sanders mainly work steel, stainless steel and non-ferrous metals. Through the grit of the sanding belt and the disc you control the result, from heavy stock removal to a fine finish. A consistent surface depends on the right combination of abrasive and cutting speed.

Who benefits from the machine?

A dedicated belt and disc sander saves time wherever deburring and reworking happen regularly: in metal fabrication, structural steelwork, maintenance and training workshops. It replaces laborious hand work, delivers reproducible edges and keeps the workshop clean where dust extraction is fitted.
