Hole Finishing Application Example Heat Exchanger • Tube Sheets TRM – TOP REAM MODULAR • Tube holes Ø 25,25mm (.994"). CHALLENGE • Tolerance range 100 μm. • Alloy steel, long-chipping. • Machining center with internal coolant. SOLUTION • Six cutting edges. • Coated cermet. • Standard 5 x D body clamped into hydraulic chuck. CUTTING • vc = 90 m/min (295 SFM). DATA • f = 0,48 mm/rev (.019 IPR). RESULT • After more than 30 minutes only minor wear visible. BENEFIT • Reduction of machining time in total to less than 60 minutes per plate with 180 holes. • Predictable tool life as only 2 μm diameter deviation after 30 minutes tool life. W78 widia.com
