Press Brake Deflection Compensation: Causes of Angle Variation on Long Parts and How to Control It
When bending long workpieces, many operators encounter the same phenomenon: the ends of the part reach the correct angle while the middle is noticeably open, or the left end is within tolerance while the right end is out. The machine is not “broken”—this is deflection at work. Deflection compensation is one of the most easily […]

How to Select Press Brake Tooling: Punch and Die Selection and Matching Principles
Press brake tooling is the core equipment of a CNC press brake. It directly determines bend angle accuracy, minimum bend dimensions, surface quality, and production efficiency. Many companies invest heavily in the press brake itself but take a “whatever works” approach to tooling, resulting in limited bend height, surface marks, and unstable angles. Based on […]

Sheet Metal Bend Allowance, Bend Deduction, and K-Factor Explained
On a bent sheet metal part, simply adding the flange dimensions gives you the wrong flat length — and a part that either won’t fit or is out of tolerance. The missing step is bend allowance. Based on the production experience of Minshuo Smart Manufacturing, this article explains bend allowance, bend deduction, and the K-factor, […]
