Stem

Produced from titanium due to the material’s modulus of elasticity being similar to that of bone, hip stems can be designed as modular or monolithic components. Extreme taper tolerances must be held to ensure that components mate optimally when implanted. Some versions also incorporate threaded holes for positioning and extraction, requiring a highly accurate thread milling process.

YOUR MANUFACTURING CHALLENGES

Achieve high quality surface finish
Maintain tight tolerances within the neck dimension
Maintain tight tolerances in holes
Maintain size tolerances
Improve surface quality

FINISHING OPERATIONS
Your Challenge:		Achieve high quality surface finish
Our Solution:		Using insert VCGT160404F-AL-TS2050 for better tool life allows for consistent surface quality in the end component.
Product:		VCGT Inserts
Your Benefit:		Superior quality
Ideal for:		Stems

TURNING HIP REPLACEMENT COMPONENTS
Your Challenge:		Maintain tight tolerances within the neck dimension
Our Solution:		Jetstream Tooling delivers a jet of high pressure coolant to the optimum position of the cutting edge to rapidly cool chips and make them brittle and easier to control. The system also lifts chips from the rake face, to stabilize the machining process and allow the use of more aggressive cutting data.
Product:		Jetstream Tooling
Your Benefits:		Increased tool life Higher productivity Better chip control Improved accuracy
Ideal for:		Stems

HOLE DRILLING AND CHAMFERING
Your Challenge:		Maintain tight tolerances in holes
Our Solution:		A custom drill and chamfer tool specific to a component’s required tolerance provides a unique solution that combines two processes into one and achieves perfect results on every part.
Product:		Seco Feedmax™ Custom Drill & Chamfer
Your Benefits:		Less scrap Decreased costs Higher profitability Higher productivity Superb quality
Ideal for:		Stems

HOLE THREADING
Your Challenges:		Maintain size tolerances Improve surface quality
Our Solution:		The Threadmaster family of solid thread milling cutters performs high-precision threading of components. When applied with Seco’s Threading Wizard software, manufacturers can adapt the method of threading holes to increase quality and reduce cycle times.
Product:		Threadmaster™
Your Benefits:		Increased precision Less scrap Reduced cycle times
Ideal for:		Stems
