Connecting rod bore and chamfer

Minimizing set-ups and wasted motion

► Bore, chamfer and back chamfer

Connecting rod

Spot facing tool

Combined boring bar

• Low cost solution for maximum productivity

• Complete boring of connecting rod heads withasingletool

• Wide range of standard inserts for roughing, finishing and chamfering operations

• Very accurate industrial seat pocket allowing a high quality surface finish

• Large choice of standard positive inserts available in a full range of cutting materials (coated and uncoated carbide)

• Milling of screwhead bearing surfaces

Gains:

• Rough bore the crank bore and chamfer both sides ofthe connecting rod in one part fixturing

• Eliminates the need for

an "A" load /"B" load strategy

• Process allows machining of eight rods simultaneously
