Centrifugal disc system finishes thin
parts
Tandem centrifugal disc finishing systems process flat, very thin discs, deburring in alternate directions, radiusing to round sharp edges, and achieving smooth polished surfaces.
Rosler's FKS 06.1 A2/So and FKS 15.1 A2/So centrifugal disc finishing systems, in use at an international automobile manufacturer, are proof that precision and speed are not mutually exclusive These machines were developed to process flat and very thin discs, deburring in alternate directions, radiusing to round sharp edges, and achieving smooth polished surfaces

Overhead rail shotblast system is Europe's largest
Europe's largest overhead rail shot blast system has been installed at a German iron foundry to to clean and remove residual casting sand from wind power system components.
Two, working as one, is the short description of the system concept.
Two tandem centrifugal disc finishing machines share a parts loading unit.
The pair also share an R 150 RT-So circular dryer.

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.
When processing discs as thin as 0.2mm, it is critical that batch integrity be remained, the discs not be damaged, and the quality be consistent.
To achieve these requirements, it is necessary to precisely control the seal gap between the casing of the work bowl and the rotating base place of the centrifugal disc.
In this system, the seal gap, formed by the rotary table and work bowl casing made of wear-resistant construction, is only 0.15mm.
* High precision in the seal gap area - particularly when processing thinner parts, the system technology must be able to ensure that the parts don't get stuck in the seal gap.
Randouml;sler technology was designed to prevent negative effects due to temperature changes that can reduce the seal gap size in other centrifugal disc finishing machines.
At the same time, all peripheral equipment, such as loading units, buffers and screening machines had to be designed with no gaps, and equipped with an anti-adhesion package to keep the flat, thin parts from sticking together.
In order to achieve precise separation for a wide variety of parts, it is necessary to be able to program different separation speeds, as well as to change the incline of the Vario buffer.
This combination ensures optimum loading and unloading of parts, and media.
At the same time, the undersize media screening process (separation of usable and waste media) is optimal.
Different parts, different process parameters and times, individual drying cycles, time-variable separation processes-all combined in a programmable logic system control unit, which also includes parts loading with apportioning of batches.
Tandem systems update - fully automatic single-batch systems have been developed to supplement the existing fully automatic double-batch systems.
Rosler's engineers have been working on the concept, and this system was unveiled at trade fairs in Germany in 2006.
