“Amazing Ideas / Facts!”
A traverse type of valve finisher (V/F) from our highly reliable and unique technology as a special tool maker, enables highly accurate machining.
The slider, the key part to traverse machining, uses a unique mechanism to stabilize machining accuracy over the long term.
“Quick-Change” and “ATC” type are available, contributing to ‘multi-product support’ and ‘improved productivity’.

Background / Point for Development
Background
- Traverse type of valve finishers were mainly made overseas, and often had problems with tool unit price, delivery time and after-sales support.
- It took longer setting up time on a machine spindle, due to the complicated installation work involved.
Point for Development
- Our highly reliable and unique technology enabled the domestic production of “Traverse V/F” (Valve Finisher), reducing its maintenance costs by extending the tool life.
- The quick-change technology, developed in tool manufacturing is incorporated also for the valve finisher, to improve the efficiency of tool changing.
