HEULE Precision Tools will feature their BSF tooling for automated high-volume back spotfacing applications in Eastec Booth #4088. The BSF tool, ideal for counterbores up to 2.3 x diameter and ranging in size from 6.5mm to 20.5mm (0.256” to 0.807”), is sold standard-stock, shipped the next day from the Cincinnati, OH warehouse. This unique tooling works without an anti-rotation device, change of spindle direction, or any machine adaptations, allowing components to be spotfaced in the same direction as the bore is drilled. This saves the time and cost of turning the work piece, while allowing the spotfacing of difficult to reach areas like yoke forks, screw-head countersinks, and more. The blade expands using centrifugal force when activating the spindle, and retracts from coolant pressure, which moves a piston to depress a pin, retracting the closed blade into the housing. The simple swing mechanism combined with the internal coolant pressure system yields optimal cutting performance, resulting in consistent spotfacing and fewer scrapped parts. The tool works both vertically and horizontally, with replaceable carbide-coated blades for extended tool life. They are ideal for gear housings, yokes, engine casings, and other parts in a wide range of materials.
