Hole Finishing Tool Selection Guide NOTE: Surface roughness values are guidelines and depend on the application, coolant situation, machine, and cutting data applied.

Hole Finishing Application Example Cylinder Head • Four usable cutting edges per CBN insert. • CBN RIQ insert with 28,000 bore tool life. • 1,400 bores with regrindable RMS reamer. • Cost savings due to four edged full face CBN insert. • No insert back taper adjustment needed. • Same RPM at both stages saving time of spindle

Hole Finishing Application Example Cylinder Head Polished flutes chip evacuation PCD SEAT & GUIDE PARENT BORE PCDRSC04RLE Valve seat and guide parent bore machining combined. Machining center with internal coolant. • Productivity increases as same RPM applied to both seat and guide stages. • Lowest possible run out resulting in higher tool life.

Hole Finishing Application Example • Tool life of 18,000 valve seats per roughing insert. • Tool life of 12,000 valve seats per roughing insert. • Twelve usable cutting edges per full face CBN insert. • Due to high precision RIQ pocket seat there is less setup effort as no angular adjustment of the insert is needed. • Able to adapt RMS " solid carbide reamer machining the valve guide.

Hole Finishing Application Example Cylinder Head Semi finish stage after pilot hole RMS " VALVE GUIDE MACHINING ■ Valve guide bore 0 6mm (.236"). ■ Brass material, lead free. ■ Concentricity of seat to guide less than Í UTTING DATA RIR VALVE GUIDE MACHINING > Valve guide bore 0 6mm (.236'" > Brass material, lead free. > Concentricity of seat to guide less t UTTING DATA > Tool life of 100 bores. > Secure process due to very good chip control on lead free brass. • Tool life of 3,000 bores. • Productivity increases due to four effective cutting edges compared to one with padded reamers.

Hole Finishing Application Example MOTION TOOLING VALVE SEAT & GUIDE MACHINING ■ Semi-finish and finish machining of primary seat angle and valve guide in one operation. ■ Transfer line with internal coolant. • Higher accuracy of valve seat angles as machining result is independent from insert wear. • Time saving combination with valve guide reamer.

UTTING DATA » Machining center with internal coolant. PCD tipped, carbide based tool with PCD guide pads > Two effective cutting and chamfering teeth. UTTING DATA • Tool life of 125,000 holes. • Surface finish better than Rz 1.5 urn. • Secure process and very good concentricity. • Tool life of 400,000 bores. • Surface finish better than Rz 3 urn. • Secure process due to chipformer in carbide body improving chip formation....
