Amazing facts!

── Introducing ideas and technologies ──

The floating deburring hand is a hand for cooperative robots to grip deburring tools.
The components are made of CFRP (carbon fiber reinforced plastic) additive manufacturing, which has a high strength-to-weight ratio and enables the production of free-form shapes that cannot be produced by conventional machining methods.
The machine can follow even complex workpieces and remove burrs stably, significantly reducing the time required for teaching.

This is the point!

Lightweight due to CFRP and hollow interior

Excellent!

Through CFRP additive manufacturing, Floating deburring hand achieves weight reduction to 1/10th: from 4.5kg to 450g.

Weight reduction is achieved by material replacement from metal to CFRP with a specific gravity: 1.2 g/cm3 and hollow internal structure.

This is the point!

Float mechanism utilizing the elasticity of CFRP to follow even complex workpieces

Excellent!

Floating deburring hand's floating mechanism reduces teaching time by 50%.

Development / product concept

“Current status and challenges”

  • The introduction of robots has become one of the solutions to the need to save manpower, resources, and energy at manufacturing sites due to the promotion of smart factories and carbon neutrality.
    However, “introduction of a robot” does not necessarily mean immediate automation. In order for a robot to work in place of a worker, it is necessary to select a hand and teach the robot to move it.
  • The hand is required to be lightweight due to the robot’s limited payload, and the introduction of a robot requires securing human resources with teaching skills and reducing the time required for teaching.
  • As the need for automation is increasing in the deburring process as well, there is a need for a function that can follow complex-shaped workpieces with minimal teaching.

“Development points”

  • The “Floating Deburring Hand” uses CFRP additive manufacturing for its components, enabling the production of free-form shapes that cannot be produced with conventional machining methods, along with a lightweight, high-strength body.
  • The robot arm does not need to be concerned about the payload when selecting a robot arm, and can follow even complex workpieces to remove burrs stably, significantly reducing the time required for teaching.
  • The high-float mechanism, which takes advantage of the characteristics of CFRP, requires no drive source and can be adjusted to the optimum float force according to the workpiece.
