Steering Knuckle Production

Ball Bearing Location:
Your Challenge:	Increase productivity by reducing cycle time and tooling cost per unit.
Our proven Solution:	Custom multi-step boring bar that roughs, semi-finishes and chamfers. The grooving tool uses double sided ISO / ANSI inserts. The illustrated special boring tool performs a rough and semi-finish bore for the bearing seat and chamfers its lead edge all in one motion. The special groove cutter mounted at the end of the boring head is designed to interpolate a retaining ring groove in the bearing bore once the finish bore tool clears the part upon retraction.

Ball Bearing Location Finishing:
Your Challenge:	Obtain the required bore geometry with a low cost per operation.
Our proven Solution:	Bifix reamer is the right solution to meet the simultaneous requirements of high quality and low tool cost per operation. Bifix technology features an indexable cutting blade and multiple guide pads that provide roundness and excellent surface finish. Different grades and geometries are available to cover nodular cast iron and forged steel.

Steering Arm Location:
Your Challenge:	Increase productivity by reducing cycle time and tooling cost per unit.
Our proven Solution:	Seco built a special arbor to combine a set of standard disc mills with a standard Square 6™ mill to create a combo straddle mill / face mill gang cutter. All cutters use standard inserts. The resulting savings include the time that would otherwise be spent on an additional tool change and multiple refixturings.

Lower Arm Ball Joint Location:
Your Challenge:	Meeting productivity and quality requirements when finishing long tapered bores on truck steering knuckles.
Our proven Solution:	To allow for high table feed while maintaining accuracy, the Bifix reamer uses a coated blade and multiple guide pads to maintain stability. The coated blade provides long tool life and excellent surface finishes. Your benefits include highly productive precision machining with lower production cost.
