Trepanning
Trepanning is a drilling process that leaves a core. Trepanning is a deep hole drilling process that has broad application over many industries. In many cases, trepanning is meant to be a roughing operation to be honed for finish, or machined further. In other cases, the trepanned hole is fit for use ‘as-drilled’.
The common factors for choosing trepanning are a long design, through bore, and within size ranges of 4.1″ to 15.75″.
Trepanning can be utilized in:
- Machinery and Heavy Equipment
- Manufacturing and Rebuild
- Oil and Gas
- Aerospace and Defense
- Metals Production and Distribution
- Forging
Can be utilized when holes may be required in:
- Finished Parts for Weight Reduction
- Clearance
- Fluid Flow
- Working Cavities
- Machining Blanks
- Piston and Cylinder Features
- Seals
