RHC420 Long Reach Robotic Arm for Punching Press




4 axes

Working radius




Main Features

  • HNC-RHC420 industrial robot is mainly aimed at large punching machine industry.
  • 4 axis robot with relatively low cost and absolute advantage in price.
  • Its long and flat robotic arm has good flexibility and long reach coverage.
  • Adaptable to narrow working space when load and unload pieces for punching press.



1. Extra-long arm extension

The long reach robotic arm has a super-long arm span up to 2000mm and its working field is bigger.


2. Overload capacity

The payload capacity of the robot is up to 20kg, and the workpieces’ size can reach 1800mm*1000mm.

3. Ultra high precision

The long arm robot has super high precision, the accuracy reaches 0.08mm, fully meet the use of punching industry.

4. Fast customized

The robotic arm adopts modular design and interchangeability, the arm length can be customized and replaced according to the actual working conditions.

5. Having innate advantages

Its 20kg load and 2000mm arm length can completely replace the 50kg six-axis robot in the punching industry with high speed, bringing high efficiency with low cost.
