Cut any hole with helical machining!

Special cutting edge design enables helical machining
Special tools suitable for high-mix production

Various hole diameters handled by helical machining

20% less power consumption due to lower cutting resistance

Reduced spindle power achieves downsizing

Amazing facts!

── Introducing ideas and technologies ──

D-cut tool supports various hole diameters with a single tool by helical machining.
High-speed machining is realized with the most suitable cutting edge material. Low-resistance machining is achieved with multi-edge specifications and a unique edge runout adjustment mechanism.
Reduced spindle load enables spindle downsizing (in case of a conventional rough boring machine max diameter #50 to #40!). 

This is the point!

Single tooling with helical machining

Excellent!

Conventional machining
(boring process, tool ø80mm, interface #50)

D-Cut tool
(Helical machining, tool ø65mm, interface #40)

Reduced cutting resistance (torque)

Good!

More than 50% cutting resistance reduction

Reduced power consumption

Good!

20% power consumption reduction

Development / product concept

“Current status and challenges”

  • Robots are replacing human tasks on factory production lines to increase efficiency.
  • In order for robots to effectively perform a wide variety of tasks, tools need to be changed frequently.
  • However, speeding up and automating this process is crucial to increasing productivity.

“Development points”

  • The ‘ATC Stub Holder’ developed a quick-change system with a mechanical mechanism that does not require a power source, enabling speedy tool change only at the tip of the hand changer.
  • As only the tip part is changed, there is no need to prepare several tool changers, thus contributing to lower costs and improved productivity.
