FACE GROOVING USER GUIDE The Multifunction Advantage The Multifunction Advantage The HELI-FACE internal boring bar HFIR/L MC This workpiece was machined using typewith internal coolant can replace the three different three different conventional tools. ISO tools and shorten machining time by 20%. An indexable drill for bottom drilling. 1 1 A single multifunction tool machines the whole part: A standard internal boring bar with a trigon grooving, face turning and chamfering, replacing three insert for roughing and finishing. ISO tools and reducing machining time by 40%. 2 2 A single integral HELI-FACE tool HFHPL-M A standard internal boring bar with a trigon insert replaces three ISO tools and reduces for bottom machining. This operation requires machining time by 50%. a small diameter shank and long overhang. 3 3 Note: When face grooving, reduce the speed by 40% in relation to that used in face turning. The HELI-FACE Solution The HELI-FACE internal boring bar HFIR/L MC type with internal coolant can replace the three different ISO tools and shorten machining time by 20%. 609
