KN-421


Dual finish grinder

High process accuracy and productivity

For these 60 years IZUMI has been a professional manufacturer of Mass Production type Internal and External grinding machines. Izumi has developed rich expertise through the many years of supplying these types of machines to the global market. Moreover, IZUMI has combined the most sophisticated and latest technology to develop the DUAL FINISH GRINDER KN-421. It is designed to simultaneously grind the internal and external part of work pieces. In conventional production process, Internal and External grinding are performed on individual grinders resulting in longer processing time and large numbers of facilities. By adopting the KN-421, excellent process quality, higher productivity and labour saving can be realized. With "grinding" as a theme, IZUMI will continue its challenging effort to correspond to the needs of the industrial market.
