priligy order in india Notching is a metal-cutting process used on sheetmetal or thin barstock, sometimes on angle sections or tube. A shearing or punching process is used in a press, so as to cut vertically down and perpendicular to the surface, working from the edge of a workpiece. Sometimes the goal is merely the notch itself, but usually this is a precursor to some other process: such as Bending a corner in sheet or joining two tubes at a tee joint, notching one to fit closely to the other.

Pieces some feet long may be manually loaded into a single-stroke press. Smaller pieces are still generally hand-fed, limiting speeds to perhaps 100 strokes / minute.
often Almost any workable metal can be notched. It’s particularly suitable where the metal is otherwise awkward to Drill, such as Stainless Steels, Titanium or previously heat-treated aluminium Alloys.
