The Nakashimada NB42 is developed responding to our customer’s demand for faster ball header in order to lower production cost of steel balls.  We have reviewed the machine structure and mechanism such as energy-saving, noise, vibration, heat generation to address most of the environmental issues.  We managed to reduce noise level to 83db with continuous operation at 1,000PPM in practice.

The toggle mechanism by cam is adopted on the back and forth movement of ram.  This prevents heat generation and air is not used for part discharge.  Noise reduction was enabled by adopting a positive cam on each mechanical structure.  To reduce machine vibration, which is a problem at high-speed operation, we seeked the higest precision on all machine part manufacturing.  Strength analysis was performed on each part which are then redesigned to make it lighter while maintaining the required strength.  It is currently under improvement with the aim of production speed at 1200PPM.

The Nakashimada hot formers are developed as a total solution equipped with induction heating system and thermo control to produce precision aircraft parts of hard-to-work materials on cold forging such as titanium, Inconel 718, Waspaloy, etc.

Induction heating system is a non-contact, energy-saving heating type for heating electrically conductive material only at the zone to be heated.

- The Nakashimada hot formers such as NS80HF, NP81HF, NP121HF and NSX80 have been delivered to customers worldwide.

The Nakashimada NSX80 is developed aiming at speeding-up of job change over and  exclusively as a hot former with induction heating equipment.
Tooling setup time for die block, punch cassette, wire stopper has been significantly reduced to only 10 minutes.
Nakashiamda in-house developed computerized automatic Numerical Control System, NCS, is equipped as standard.
