Bending stainless steel without surface damage
Why 304 and 316 mark on the press brake, what galling actually is, and the radius, die opening and tonnage numbers that keep the face clean.

Bending, welding and finished assemblies
A bend is where a flat drawing becomes a part, and a weld is where several parts become an assembly that either fits at the customer's line or does not. Ganesh bends on a 200 T, 4,450 mm, 5-axis CNC press brake and welds on three CLOOS robotic cells plus more than 30 manual stations. These guides cover K-factor and bend allowance, minimum flange, springback, long-panel distortion, fixture design, weld sequence, assembly tolerance stack-up and inspection.

Press brake bending, bend allowance, fixtures, robotic MIG welding, distortion control and the tolerances a finished welded assembly can actually hold.
