TREPANNING:
A machining process used to produce heavy wall tubulars from solid bar. This process provides a wider variety of OD and ID combinations than is typically offered in a standard tubing product. Another significant advantage is that unlike "mill run" tubing items, there is no minimum quantity on a trepanned product. Pieces as short as 6" or as long as 40' can be machined with the ID as specified by the customer. The delivery time for trepanned bar is usually in days rather than weeks or months.

SAW CUTTING:
We can provide material cut to length, with a maximum OD capacity of 20"

BORING -PULL/PACK:
Machining process used to enlarge an existing ID either on tubing or trepanned bars. Produces a closer tolerance and improved concentricity.

HONING:
Process used to improve the ID surface finish and to achieve very close ID tolerances.

OD TURNING:
This process is commonly used to reduce the outside diameter of a bar or tube. OD turning can also be done in lengths up to and including 40' long, depending on the weight of the piece of material.

OD CENTERLESS GRINDING:
This process produces close tolerances and superior OD surface finishes.

STRAIGHTENING:
Process used to "straighten" either solid bars or tubing, usually done before other machining processes mentioned above.
