TMI offers milling and skiving technologies to produce a wide range of contour profiled strip products. Skiving produces a smoother surface in the grooved section; milled products are typically lower cost.
The Contour Profiling Process
Skiving
A continuous shaving process which results in a smoother surface finish than is possible with milling.
Milling
Metal strips are fed through a series of milling cutters to produce section profiles that allow for more cost-efficient stampings.
The Contour Profiling Advantage
Both Processes
Minimizes or eliminates coining
Extends die life
Minimizes maintenance costs
Allows tight tolerance for steps, angles, and radii
Reduces final costs
Skiving
Imparts a smooth surface finish (6-8 RMS) while eliminating subsequent coining in the contoured area, providing an excellent surface for plating and often reducing the required precious metal thickness
Works with Extra Spring and Mill-Hardened BeCU tempers
Provides a flat, camber-free material for high-speed, precision stamping
Generates lower costs on certain configurations involving minimal metal removal
Milling
Eliminates coining
Introduces the least residual stress in to the metal
Can further relieve residual stresses by either thermal or mechanical stress-relieving steps
Reduces handling and assembly costs
Reduces your final cost per piece
Replaces the need for two or more parts
Extend the life of your die and simplifies design
Provides milled shapes for hard or soft temper materials
Option of large coils for uninterrupted stamping
Enhances your component design
Allows tight tolerance for steps, angles, and radii
