Antivibration Tools

In a conventional method we can use tool steel for boring or reaming tools upto L/D (Length/Diameter) ratio of 5 due to its low static stiffness & damping ratio. Due to this it can be operated at relatively low RPM.

For large L/D ratios of more than 5, carbide or high density material is used because of its relatively static stiffness & damping properties against tool steel. This high density material can machine only upto 7 L/D without chattering & has following disadvantages.

Cannot use high cutting parameters due to small increment in specific stiffness.

Due to large hardness, machining is difficult & costly.

Due to high specific weight, tool becomes very heavy. Center of shifts from center particularly when operation is horizontal (HMC or SPM).

High cost of raw material as well as manufacturing.

Handling is also a key concern, due to its brittle nature & bulky weight.

Therefore we use advanced carbon fiber boring bar for antivibration boring which has following advantages over conventional methods,

1/3 rd weight of steel boring bars

times dampening than of steel

4times dynamic stiffness than of carbide or high dense tools

increased cutting parameters due to ultra light weight design
