Versatile Burnishing
Cogsdill Universal Burnishing Tools are designed for burnishing shafts, faces, tapers, contours, and relatively large IDs (greater than 2.750 inches/69.85mm).
- Boring-Bar style and Index-able turning-holder style designs
- Turning-Holder styles available with force gauges.
- Tool designs to suit any part size or configuration, or any turning machine
- Low surface finishes
- Standard, available off-the-shelf
- Adjustable for optimum burnishing pressure
- Hardened steel or carbide rollers
Boring-Bar Style
The Cogsdill UBT-B series are designed for use in a machine turret configuration on a CNC lathe, where differing diameters are required from a single tool set-up.
Three basic styles are available:
- UBT-B1 (For large diameters, tapers & faces)
- UBT-B2 (For smaller diameters, tapers & faces)
- UBT-B3 (For smaller diameters where facing is not required)
Both UBT-B1 and UBT-B2 are offered with both a hardened steel roll and a carbide roll, where as UBT-B3 is offered with a hardened steel roll only.

Boring-Bar style tool operation:
- Mount any UBT-B tool in the desired boring bar station. (Note: The red orientation spot must be opposite the contact point.)
- Bring the tool into contact with the part to be burnished.
- Feed the tool another 0.003-0.005 inch (0.08-0.13mm) into the part to provide interference between the roll and part so that the roll will float in its spring travel.
- Interference should not be used to increase burnishing force; burnishing force should only be adjusted with the load adjusting screws. This ensures the tool can be fed on/off the part and across interruptions without damage to the tool or workpiece.
- For optimum results and long tool life, coolant is required. Any soluble, synthetic, or straight oil can be used.
- Whenever possible, and for best results, the tool should be fed towards the spindle when burnishing diameters and towards the centerline when burnishing faces. (Note: the UBT-B3 tool cannot be used to burnish faces.)
Turning-Holder Style
The Cogsdill UBT-T series are designed for use in an indexable turning holder configuration, mounted to a machine turret on a lathe.
Four basic styles are available in both left-hand and right-hand versions.
- UBT-T1 (For outside diameters, faces, tapers and contours)
- UBT-T2 (For outside diameters only)
- UBT-T3 (For large outside diameters only)
- UBT-T4 (For outside diameters where limited space is available)
The UBT-T1 and UBT-T2 are offered with a carbide roll as standard. The UBT-T3 and UBT-T4 are offered with a hardened steel roll only. A force gauge option is available on the UBT-T2 and UBT-T3.

Turning Holder style tool operation:
- Mount any UBT-T tool in the desired turning station. Use a UBT-T tool that corresponds with the respective turning tool.
- Bring the tool into contact with the part to be burnished; contact has occurred when you see the mandrel rotating.
- Feed the tool another 0.003-0.005 inch (0.08-0.13mm) into the part to provide interference between the roll and part so that the roll will float in its spring travel.
- Interference should not be used to increase burnishing force; burnishing force should only be adjusted with the load adjusting screws. This ensures the tool can be fed on/off the part and across interruptions without damage to the tool or workpiece.
- For optimum results and long tool life, coolant is required. Any soluble, synthetic, or straight oil can be used.
- Whenever possible, and for best results, the tool should be fed towards the spindle when burnishing diameters and towards the centerline when burnishing faces.
- Note: UBT-T2 and UBT-T3 tools cannot be used to burnish faces.
