NAKANISHI develops high-speed spindles, precision micro grinders and ultrasonic systems for demanding machining. The solutions cover milling, drilling, grinding, polishing and deburring – from manual work in the toolroom to use on CNC machines and in robot cells.
High-speed machining on your existing CNC machine
Add-on HES electric spindles extend the capabilities of your machining centre or milling machine. Versions available are HES510 up to 50,000 rpm and HES810 up to 80,000 rpm, particularly suited to drilling and milling with small tools.
Different shank versions allow adaptation to your machine, and the E3000 controller lets you set the speed and monitor the load. The system also supports external control and operating-status monitoring.
Precise manual grinding, polishing and deburring
Emax EVOlution and Espert 500 micro grinders allow fine work with a range of handpieces and attachments. On the Emax EVOlution system, brushless motors ensure smooth, low-vibration running, and the load display helps you keep the work under control.
For air-driven work, the ROTUS, IMPULSE and PRESTO II systems are available. PRESTO II reaches up to 320,000 rpm and is also intended for chamfering, deburring, engraving and machining ceramic components.
Ultrasonic machining of demanding details
Sheenus ZERO is used for grinding and polishing small corners, narrow ribs and other hard-to-reach areas of a mould. It is also suitable for removing the surface layer after EDM and achieving a fine final finish.
Sonic Cutter ZERO is designed for ultrasonic cutting and deburring of plastics, composites and various thin materials.
Spindles for automation and robotic machining
Compact NAKANISHI electric and air spindles can be integrated into CNC lathes, special-purpose machines and robotic systems. Depending on the version, they are suitable for automated drilling, milling, grinding and deburring.
