Heule Precision Tools features its BSF tooling for automated high-volume back spotfacing applications. It is designed for counterbores up to 2.3 times in diameter and ranging in size from 6.5 to 20.5 mm (0.256" to 0.807").
BSF tooling is available with three activation methods to suit various machining environments, including, CNC machines with through-spindle coolant with at least 300 psi; CNC machines with through-spindle air with at least 60 psi; and a manual version with simple collar locking and unlocking mechanisms. BSF tooling is designed for CNC machining and functions without an anti-rotation device, change of spindle direction or contact mechanism, enabling components to be spotfaced in the same direction as the bore is drilled. This can save the time and cost of turning the workpiece, while enabling the spot facing of difficult-to-reach areas like casting flanges and bolt head faces. The simple swing mechanism combined with one of the three activation methods yields optimal cutting performance, which results in consistent spot facing and fewer scrapped parts.
BSF tooling is stocked in a Cincinnati area warehouse for immediate shipment. They are ideal for gear housings, yokes, engine casings and other parts in a wide range of materials.
During operation, the back spotfacing and counterboring tool blade expands using centrifugal force when activating the spindle and retracts from coolant pressure, air pressure or manually. This moves a piston to depress a pin which retracts the closed blade into the blade housing. The tool works both vertically and horizontally, with replaceable carbide-coated blades for extended tool life. Designed for optimal cutting performance, chip removal and reliability, the BSF coolant-through tool and blade feature coolant pipes and chip-guiding geometries that continuously flush the blade window and the blade itself with coolant. This keeps the work area clean and enables optimal chip removal. All tool components and blades are simple to replace.
