Producing the Best Boring

Setting up the tooling

• By using the largest boring bar for the hole, there is maximum clearance to allow for better chip evacuation and minimize deflection. 
• Center alignment of the boring bar cutting edge on the horizontal center of the hole stops inferior cutting.
• To minimize tool overhang and reduce vibration, the operator needs to keep the boring bars short to increase rigidity and stability. 
• Rigid holders will secure the boring bar better than set screws by fully wrapping around the shank. 

Controlling the cutting process

• The most critical factor on tool life is cutting speed, which the operator must properly adjust to the material and tool type. 
• The higher the feed rates, the less chip wrapping around the tool occurs. 
• A greater depth of cut on finishing passes lessens side forces and deflection. 
• Chip control is achieved by employing the appropriate feed rate to break up the chips efficiently. 
• High-pressure coolant (HPC) may be needed to effectively flush chips and prevent bore damage or wrapping around the tool.
• Step boring is necessary for deep holes to efficiently evacuate the chips to prevent buildup at the bottom.
