Page 10: Product Overview
The FDB Deburring Spindle is a robust, high-speed and lightweight air turbine-driven deburring unit for deburring aluminum, plastic, steel, etc. with a robot or CNC machine. The FDB is especially suited for removal of parting lines and flash from parts. However, its flexible design allows it to be used in a wide variety of applications. -

Because the working environment is unknown it is impossible to predict the noise that will occur during a deburring operation. The FDB may also excite resonant frequencies on equipment to which it is mounted creating higher sound pressure levels than the unit by itself.

Page 21: Operation
Countersinking and other axial metal-forming processes should not be performed by the FDB. It may be dangerous to operate the FDB deburring tool for these purposes. If a failure occurs due to forces caused by improper use, hazardous situations for both personnel and equipment could be created. -
Page 22: Working Environment
Be aware of rotating parts. Use eye-protection while working around the FDB. Be aware of high sound levels. While the FDB air motor is not loud, the cutting action associated with deburring frequently is. Always use hearing protection while working in the neighborhood of the deburring cell. - Page 23 M4 x 16 mm into the threads on the housing from which the 4 hexagon socket screws M5 x 6 mm were removed.

This can quickly load a cutter and produce unacceptable results. In general, the traverse or feed rate of the FDB will be higher for plastics to minimize this behavior. This results in larger cuts, which more effectively remove heat from the cutter-tool interface. - Page 27 Fiberglass Router, Straight, 1/8" Burr Diameter, 1/2" Burr Length, 1/8" Shank • For trimming and contour milling of all • Special cut geometry allows high glass and carbon fiber reinforced feed rates due to low cutting plastics forces 04.00 | FDB | Assembly and Operating Manual | en | 389072...
