HEULE PRECISION TOOLS launches at EMO their latest development. The new BSF tool extends their range for automated high volume production of back spotfacing and counterboring at an interesting price level. Now, a counter bore ratio of up to 2.3 x d is possible. The tool is used for diameters from 6.5 to 20 mm without having to turn the workpiece over. The productive efficiency is distinguished by its process capable, proper functioning and high cost effectiveness thanks to fast process cycles and a minimum of secondary time.

As most innovative provider of tools for processing both bore edges in  a single pass, HEULE presents another first class solution for back spot facing. Since the machining is done from the same side as the bore is drilled, it is also possible to apply spot faces or counter bores in areas that are difficult to access such as bores between the forks of yokes or screw head counter sinks.

The goal of this development was to assure the crucial process capability for large volume production of diameters of up to 2.3 x d. The BSF is specifically designed for CNC machining and is immediately ready for production.

The high competivity is based on its at the same time compact and simple design concept and function principle that can do without preadjustments. HEULE succeeded in merging the advantages of a simple folding mechanism with the required process capability of series production. In addition the long tool life of its blade accounts for a minimum of machine downtime.

The design concept of the BSF tool systems is convincing. The blade unfolds by activating the spindle with an initial rpm and by the gravity of its own weight. An impuls of the internal coulant folds the blade back in on demand. This means that the tool requires a machine equipped with an internal coulant of approx. 20 bar working pressure. Be it aluminium, high grade steel or inconel and titan the tool together with the specifically coated blade can work a great variety of materials. If the tool needs to be serviced due to wear, its components such as blade, pin or split pin can be replaced easily on your own.
