The brushing-honing technique has been used by GERBER
MASCHINENBAU for over 50 years. The machines were
initially used for processing and polishing of ruby jewel

bearings in watches, but later also for radiusing and
polishing of indexable inserts produced in Tungsten
carbide and CBN.
The BS 250 brushing machine has been specially developed
for de-burring and defined radiusing of edges on precision,
mass produced components. Up to 1.5 million components
can be processed annually in single-shift operation, depending on the workpiece material and diameter.
The machine is particularly suitable for precision components, such as valve plates, pump parts, rotors, indexable
inserts, etc., for which there should be a requirement for
high surface quality and parts free of all burrs.

MAIN FEATURE S
• Solid construction to ensure high accuracy
• The planetary brushing head produces
evenly radiused edges all round
• Designed for high production batches
• Open-type machine concept permits optional loading and feeding devices to conform with the range of components
• Turn over station for processing both sides
of component
• User-friendly, with very simple programming of processing parameters and easy
tool change
• Fully automatic processing
• Continuous compensation for brush wear
• Working area completely enclosed
• Processing can take place dry or with
coolant, depending on application
