Deburring has become much more
advanced than ever. Variety of deburring machines has evolved making the
process easier than before.
However, there are many types of
burrs. If sheet metal needs to be processed, it can be done with two types of
burrs – mechanical and thermal. A mechanical burr is created by punching,
drilling, sawing.
A thermal burr usually occurs
during laser cutting.
The deburring system contains a
variety of tools, like belts, brushes, abrasive mop wheel with
spindle. Brushes and belts are best used for the application. Initially, a
single head abrasive belt machine was most common.
Wet or dry
It is an old debate, however,
each system has its benefits and drawbacks.
Wet deburring machines flood
coolant into work surface. Gravity takes the dirt and grinding particles along
with coolant to a filter where they are trapped. Some machines have filtering
system. The wet system eliminates the need of a dust collector and minimizes
hazards while working with different metals.
Dry machines leave dust particles
and grit on the work surface which needs to be cleaned. However, dry machines
require less maintenance, and typically they have a longer machine life. They
are also less expensive to purchase.
