3 Ways A Robotic Automated Brake Helps
REDUCE HUMAN ERROR
The more manual parts of your production process, the more opportunity for human error. A robotic press brake helps to reduce human error in several ways. A robotic press brake is programmable and produces the same part with consistent accuracy. It also adjusts to compensate for operator error.
The machine compensates if the operator accidentally uses too low or too high force.
That means a robotic press brake produces quality parts every time, even if the operator is new or making a mistake.
Robots also don't get tired or distracted. A production line pauses while an operator takes a break, slowing production.
A robotic press brake runs 24 hours by programming, requiring no rest and helping consistently meet production goals
INCREASE PRODUCTIVITY
A robotic press brake dramatically increases your production capabilities. With a press brake, you get one shot at forming each part.
The press brake brings the metal sheet down onto the part to be formed, finishing the part.
However, robotic press brakes are programmed to move metal sheets without continually forming them.
This process allows the machine to form multiple parts, making no adjustments to the machine after the first part is formed.
Thus, a robotic press brake forms multiple parts while only taking up the same amount of space as one press brake.
Just like a robotic press brake runs 24 hours a day, it can also be programmed to run as quickly as possible, forming parts to meet production schedules.
PRODUCE TIGHTER TOLERANCES
Consistent tolerances are essential when manufacturing parts. If different parts have different tolerances, they may not work together correctly, reducing durability.
A robotic press brake allows you to set the exact pressure that forms each part, meaning you set tighter tolerances for each part.
If you're manufacturing something that must fit together perfectly, having tighter tolerances is critical.
A robotic press brake also reads the thickness of the sheet of metal and makes minor adjustments to compensate for any thickness variations: even if your sheet metal supplier has some slightly thicker or thinner sheets than others, the robotic press brake compensates.
