Lathe Boring Bar with Integrated Damper
Big Kaiser offers its Smart Damper boring bar for lathe applications. A heavyweight, strengthened damping mechanism integrated into the toolholder functions as both a dynamic counter and friction damper. It instantaneously absorbs vibration and eliminates chatter, promoting higher machining accuracy, better surface finishes and increased metal removal rates for higher productivity at critical machining depths, the company says. It supplies coolant through the body directly to the cutting edge.
The boring bar features three modular insert holders optimized for right-hand ID turning with ISO-standard inserts at a minimum diameter of 1.58". Metric bodies are available in 32 and 40 mm in diameter, with inch versions at 1.250 and 1.500". This system is said to enable boring depths of approximately 7×D.
For this contract shop, it's what happens before heat treat that ensures hard turning process success. They've learned getting it right early eliminates problems later.
A methodology for cutting in both directions on a CNC lathe promises to make turning a much more productive operation in certain applications. New types of inserts driven by new CAM tool paths are key enablers of this development, but implementing the whole multifaceted system as a system is essential.
Form tools are traditionally associated with non-CNC machines, but in certain applications they make sense on modern machines as well.
