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 100mm to 400mm.
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
