Before it is made – through bending,
end forming, chamfering, drilling, punching,
milling – into a product, a tube is known as a blank.
And a blank it will remain if it is not cut with caliper
precision: clean, straight, to length. If this process is
not right, it will matter very little what else is.
No amount of subsequent effort will rescue a profile that
has been compromised from the first pass of a blade.
Tube makers know the critical importance of accurate cutting.
Saw cutting. Lathe cutting. Rotary cutting. Dual-blade shear
cutting. Supported shear cutting. Every one of these is
virtually a technology in itself. An informed awareness of the
distinct benefits and challenges of each technique is second
nature to the providers of the products and services
reviewed in this section of
Tube & Pipe Technology
