Deburring and Deflashing Machines Information

deburring and deflashing machinesDeburring and deflashing machines remove burrs or dross, smooth or deflash parting lines, round off sharp edges, and radius corners on machined parts, castings, forgings, molded components, and welded assemblies.

Finishing, cleaning, polishing , dusting (dedusting) is accomplished through a relative motion and pressure between the brush and the work piece. The bristle scrape up against the surface removing a minute amount of material. The rotary brushes are rotated and/or reciprocated or oscillated while the work piece is pushed against the brush face. On finishing or cleaning of large surfaces such as sheet metal or floor, the brush face is pushed against the work surface.

Construction 

Most deburring and deflashing machines consist of a steel housing with a motor, spindle, brush mount mechanism(s), control system for motor speed, feed rate , and/or tension or pressure between tool and work piece surface. The machine may have a conveyor or table for mounting and feeding parts.

Types

Deburring machines remove burrs from machining, grinding or drilling, round off sharp edges, and radius corners on machined parts, castings, forgings, molded components and welded assemblies.

Deflashing machines remove flash, dross or parting lines on castings, forgings, molded components and welded assemblies. The sharp edge of a parting line or flashing could be considered a burr, so in some respects a deflashing machine is a subset of deburring machines. However, specialized deflashing tools is sometimes used in presses or press like equipment to shear the flashing from a part. This type of deflashing machine is not a subset of deburring machinery.
