Typical Bushing Applications
Gatco Rotary Bushings can be incorporated into many machining operations requiring precision machined parts. They provide superior support of rotating cutting tools while eliminating friction and wear. Rotary bushings are commonly incorporated into older equipment as well as new. With the demand for continuous improvement and tighter tolerances, Gatco Rotary Bushings are the answer to your machining problems. Contact Gatco and send your requirements for an immediate design and quotation.
Typical Bokumatic Recessing Application
As shown in the drawing, Gatco offers a standard line of rotary bushings designed specifically for use with recessing toolholders. Their unique construction incorporates a radial bearing to accept side loads as well as a thrust bearing to accept axial loads generated by the toolholder activating mechanism and the cutting forces. Recessing bushings can be used in any operation where axial forces are encountered.
Typical Rotary Bushing Support Application
Rotary bushings are commonly used to support and guide shank type holders.They eliminate the wear of the holder pilot diameter, whether this surface is bronze, carbide, or hardened steel wear strips. Rotary bushings are commonly incorporated as an after market replacement for the drill bushings which may have originally been designed in. A rotary bushing can usually be incorporated by simply removing the liner and drill bushing from the bushing plate and replacing it with a rotary bushing.
Typical Boring Application
One of the most common operations for a rotary bushing is boring. The drawing above demonstrates a typical boring operation where the process requires straight and round holes be bored and tight tolerances held. Stationary bushings are unacceptable due to their high wear characteristics which is not tolerable. Rotary bushings can be adapted to most boring applications.
Gatco's Engineering Department can provide a special design to suit your specific requirements.
Gatco Rotary Toolholders can be designed to suit any application. In addition to our four standard series, Gatco can design and build specials, incorporating coolant inducers, float mechanisms and insert pockets. Rotary Toolholders can normally be incorporated into an existing machine requiring no modifications to the machine itself. Contact Gatco and send your requirements for an immediate design and quotation.
Floating Rotary Toolholder
Rotary Toolholders can be designed to float, to allow for spindle misalignment. They allow the cutting tool to rotate on an offset centerline from the spindle. The float mechanism compensates for misalignment between the spindle and bushing plate.The anti-friction bearings provide rigid friction free support during
the cut.
Indexable Rotary Toolholder
Rotary Toolholders can be provided with the cutting inserts mounted directly in the holder. They are commonly used in combination with other cutting tools such as drills or spot facers as shown above.
Stub Rotary Toolholders
Stub Rotary Toolholders are commonly used when maximum support is required near the cut. They are compact, allowing minimum distance between the spindle and the part being cut.
