Why people assume the answer is no
Most shops have heard the version where automation means a new brake. A new brake with a
robot bolted to it is one product some machine builders sell, and it is a fine product for a
shop that needs a new brake. But the question most fabricators are actually asking is
different: the brake on the floor is paid for, it bends good parts, and the problem is the
two people standing in front of it all shift. That brake can be automated. The Way
Automation has integrated robots with twelve to thirteen press-brake brands and seven
controller types, and the pattern is the same every time.
What the retrofit changes
Three things, and none of them is the brake.
The gripper. The part decides it. Vacuum for flat sheet, magnetic for ferrous blanks
that vacuum cannot hold, mechanical fingers for parts with no flat face. It is designed for
the part family the cell will run and built in our shop, because the gripper is where most
press-brake automation succeeds or fails.
The regrip. After the first bend the part has moved in the gripper. A regrip station,
or a gridded locating table, squares it again so every following bend lands where the
program expects. Single-bend parts skip it; multi-bend families live on it.
The safety system. A documented risk assessment decides the guarding. Light curtains
cover the load points so the operator can stage blanks while the robot bends, and the robot
runs safety-rated speed and position monitoring behind the guarding.
What it leaves alone
The brake keeps its controller, its tooling, and its footprint. The robot talks to the
brake through the brake’s own I/O or a small interface, so the machine you know is still
the machine you know. Nothing ships out, and production keeps running while the cell is
built around it.
What it looks like at 150 pounds a part
Thunder Creek Equipment bends steel plate over six feet long and more than 150 pounds each
for fuel and service trailers. The Way Automation retrofitted a FANUC R-2000iB/200R onto the
Cincinnati 135-ton brake they already owned, with a custom vacuum end-of-arm tool and a
sensor-equipped regrip station. The two-operator station now runs unattended, and the bends
came out consistent enough that the robotic welding line after the brake got more accurate
too. FANUC America published it as a case study, and a second TWA cell was on order within
twelve months. The full story is on the
Thunder Creek case study.
When the honest answer is “not this brake”
There are two. A brake whose controller cannot signal the ram position at all, which is rare
and usually very old, needs a controller upgrade before a robot can follow the bend. And a
part family that changes every hour, with no repeat volume, does not give a cell enough of
the same work to earn its place. Both come out in the first floor walk, and we say so.
What to bring to the first conversation
The brake’s make, model, and tonnage; the three or four parts that eat the most operator
time; their weights and lengths; and roughly how many of each you bend in a week. That is
enough to say whether a retrofit fits and what the cell would look like. The
press brake tending page has the specs, and the
Automation Fit Check takes four minutes.
