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
