USER GUIDE The Multifunction Advantage The HELIFACE internal boring bar HFIR/L MC A single multifunction tool machines the whole 1 type with internal coolant can replace the three 2 part: grooving, face turning and chamfering, different ISO tools and shorten machining time replacing three ISO tools and reducing by 20%. machining time by 40%. FACE GROOVING A single integral HELIFACE tool HFHPL-M 3 replaces three ISO tools and reduces machining time by 50%. The Multifunction Advantage This workpiece was machined using three different conventional tools. An indexable drill for bottom drilling. A standard internal boring bar with trigon 1 2 insert for roughing and finishing. A standard internal boring bar with trigon 3 insert for bottom machining. This operation requires a small diameter shank and long overhang. The HELIFACE Solution The HELIFACE internal boring bar HFIR/L MC type with internal coolant can replace the three different ISO tools and shorten machining time by 20%. 466 466 ISCAR ISCAR
