What is Deburring?

What is a burr?

During most machining processes, work pieces become burred, and sharp edges or material compression occurs.This effects the quality of the part and can create a potential sources of error during the assembly process. 

What is burr and how does it occur?

1)   During stamping, fineblanking or forming

2)   During casting, sinter and molding of material

3)   During milling, turning, drilling und grinding

Linear Deburring Machines

Most of deburring machines can be equipped with up to four machining stations, each equipped with five brush tools. An ideal transformation ratio between brushes and head ensures constant and optimal deburring results. In the area of flexible single-part production and production of small to medium series, most of deburring machines are optimally suited for cost-effective machining of, for example, punched and precision cut parts, valve plates and precision work pieces. Most of deburring machines can either be supplied as stand-alone solution or – for further increase of productivity – as semi and fully automated setups combined with any other machine (e.g. a double-disk surface grinding machine from the DDG range). Each version follows a modular concept and can be adapted to our customers‘ needs.

Double-Sided Deburring Machines

For  high- precision  series  production  of  work  pieces, machines has been refined. Thanks  to its modular structure, it is already in use as a precision  grinding, lapping, honing and polishing machine. Now Machine manufacturers are also offering a patented solution for double-sided deburring applications in one working step. The changeover to a double-sided precision grinding  machine for deburring applications could not be easier. All that is required is to replace the precision grinding wheels by brush wheels, and to deactivate the central measurement control. this means a precision grinding machine is basically suitable for deburring, and can also be used as a combination machine.

Disc Brushes 

Countless different specifications can be configured. In most cases an individual polyamide fiber is coated with abrasives. Grain size and abrasive material play a decisive role in this.

• Silicon carbide
• Aluminum oxide
• Ceramics
• CBN
• Diamond
