Technology for the World KURAKI

Stator Core Cutting Machine for EV Motors
CNC Notching Machine KNCP Series

Adopts CNC and achieves the world's fastest speed of 1000 spm.
High accuracy and labor saving.

The KNCP Series Notching Machine evolved based on KURAKI's large machine tool manufacturing technology. In addition to high-precision indexing and high-speed punching technologies, it includes an optimal automation system with various options supports high-mix, small-lot production and test processing. Enables flexible processing to meet diversifying needs.

  • Ideal for high-mix, small-lot production of stator cores and rotor cores for electric motors, generators, etc.
  • CNC indexing mechanism can provide many necessary options for motor and generator production.
  • AC servo motors are applied for indexing, and a highly reliable FANUC controller is applied for high accuracy and speed.

High-speed machining supports multiple product types and small-diameter machining (φ50~)

Slot grooves can be punched continuously at high speeds of up to 1000 spm on steel plate base materials, making this press machine ideal for high-mix, small-lot stamping of stators and rotors made of laminated steel plates, which would normally be too costly using conventional stamping machines. Automated systems with automatic conveyors and other equipment can also be provided.
