Plunge grinding removes fine burrs
Special plunge grinding technology is used to remove protruding, very fine burrs and radius dovetails of aerospace components, such as machined engine turbine disks.
Vibratory finishing has expanded into the area of finishing and deburring delicate components Processes such as the surface finishing of high-quality individual parts, and the fully automated processing of bulk parts, are fully established in all branches of industry

Long radius deburring machines fit into lines
Long radius deburring and finishing machines can be used for in-line continuous processing and for batch processing and offer a high degree of flexibility.
A special example is the processing of disc components following the metal-cutting manufacturing process.
The removal of protruding, very fine burrs and radiusing of dovetails are among the most important tasks.
* Special plunge grinding technology - mounted to a rotating workstation fixture, the turbine disk is plunged into a work bowl filled with abrasive media.
The component is rotated at high speeds in a special reciprocating movement that returns in cycles.
The enormous grinding pressure that builds up provides an even radiusing of the exposed outer zones.
Water and compound in the work bowl help to produce consistent processing results.
* Reproducible processing result - after the processing is completed, the workstation, fixture, and component are raised out of the processing medium.
A subsequent rinsing process removes any abrasive media still sticking to the part before the it is transferred to the waiting handling unit.
For continuous process quality, reliable classification of the media after a few working cycles is a requirement.
This process will automatically screen out undersized media in a separation unit.
* Plunge-grinding in tandem operation - this separation unit can be used particularly efficiently if two plunge-grinding systems are configured as a tandem system.
Both plunge-grinding machines alternate using the same separation unit, operating parallel to the time consuming screening process, in order to avoid downtime.
* Modern control technology - the system control unit is precise yet highly flexible.
Big-surface operating units inform about the processing state.
A program control unit saves all process details and communicates continuously with the operating system of the system operator by way of direct data exchange.
* About Rosler (Roesler) - as an all-round supplier, Rosler is an international market leader in the production of surface finishing, shot blasting machines, painting systems and preservation lines as well as process technology for the rational surface finishing (deburring, descaling, sand removal, polishing, grinding, etc) of metals and other components.
