Smart Wizard Interface

Picks the safest die from your own tooling

Don't just grab the nearest die. The Smart Wizard scans your actual inventory to find the safest, most accurate tool for the job. It calculates air bend force, validates flange lengths, and warns you of tonnage overloads before you even touch the machine.

  • Tonnage Safety Checks (1.5x Factor)
  • Geometric "Impossible Bend" Detection
  • Matches against YOUR inventory

From the shop floor

Proof, not promises.

Same part, same brake, same day. Precision Form called the setup—then the gauge did the talking.

02 — The prediction

Die 37 at 84.1 tons — best fit. Die 35 at 130.8 tons — flagged high pressure before anyone touched the machine.

Jon Chacon, founder of Precision Form Tools

Built on the shop floor

I'm Jon Chacon. I ran press brakes and CNC machines for over a decade — programming, setting up, and running the jobs myself.

Precision Form Tools came straight out of problems I ran into on the floor: tonnage guessed from a wall chart, the wrong die pulled because nobody wrote the last setup down, numbers that changed depending on who was working the brake.

So I built the tool I wanted at the machine. It does the tonnage math, picks the safest die from your actual inventory, and saves the setup so the next run comes out the same. It's a JC Build Labs product. Free 14-day trial — no credit card required.
