Trepanning

Shallow trepanning using plate stock:

  • Pistons or cylinders
  • Fluid ports
  • Seals and more

Shallow Trepanning

When people think about trepanning they typically envision large, deep, round holes or hollowing of bar stock, but at TCI Precision Metals we provide a variation of trepanning, using plate stock, that we call Shallow Trepanning.

At TCI Precision Metals we use our method of shallow trepanning in the production of precision Feature-Added Machine-Ready Blanks, for example, when customer specifications require plate stock with large diameter holes or circle features, machined to close tolerances. Round flat blanks with a through or blind hole, concentric rings, and discs are all considered trepanned parts.

At TCI Precision Metals we trepan aluminum, stainless steel, and other alloys in the process of producing many different types of Machine-Ready Blanks, roughed parts, and finished machined parts, based on an understanding of what the customer is looking to accomplish. Things to consider when talking to us about trepanning, include:

  • What material and heat treatment is required?
  • If the material is being supplied, is it bar stock, forgings or castings?
  • What are the specifications and tolerances for the trepan feature?
  • Are there concentricity requirements?
  • Are there any surface finish requirements?
