Boring heads for large-scale machining come with heavy-duty shell cast iron or steel housings with strong load bearing pads supporting diameters spanning 50mm to 500mm. This allows for a two guide system which greatly dampens vibrations during deep boring operations (depth-to-diameter ratios greater than 10:1). Quick change designs for the inserts further optimize reduction of downtime. These are used in shipbuilding and oilfield equipment and can endure cutting forces of 50kN while sustaining an accuracy of 0.02mm in positional slippage.
