Traverse cut valve finisher
Leave the traverse processing of valve seats to us!
High-precision manufacturing with traverse processing
Productivity improvement by solving problems at the manufacturing site
Single process machining of valve seat and valve guide
Extended service life due to the unique slider mechanism
Contribute to productivity improvement and change in tools
Amazing facts!
── Introducing ideas and technologies ──
As a special tool manufacturer, we offer valve finishers that realize traverse machining of valve seat surfaces, which requires high required accuracy, through the elemental technologies we have cultivated and highly reliable manufacturing.
The slider, which is the key to traverse processing, employs a unique mechanism to stabilize processing accuracy over a long period of time. We have also developed quick-change and ATC specifications, contributing to “multi-product support” and “productivity improvement”.
That's the point!
Traverse processing of valve seat & valve guide in one process
Excellent!
Process ①:
Plunge machining of relief surface
Process ②:
Seat surface traverse finishing
Process ③:
Valve guide hole finishing with reamer
That's the point!
Long-life slider with a unique mechanism
Excellent!
Unique slider mechanism using wedge pressing pressure ensures stable machining accuracy over the long term
We possesses manufacturing technology to produce slider operating angles with high precision
Contributes to “high-mix production” and “improving productivity”
Good!
Quick change and ATC specifications were developed to reduce tool change time and improve production
Direct mount specification
Equipment: dedicated machine Minimum protrusion length from spindle
Quick Change specification
Equipment: dedicated machine Quick tool replacement is possible
ATC specification
Equipment: machining center (with operating shaft) Ideal for high-mix production Automatic tool change
80% tool change time reduction
- when quick change is compared to direct mount
- when ATC is compared to quick change
Development / product concept
“Current status and challenges”
- Valve finishers capable of traverse processing were mainly made overseas, and there were problems with tool unit price, delivery time, and after-sales support.
- In addition, when setting up the machine on the equipment spindle, the installation work was complicated, and lot of time was needed to change the tool.
“Development points”
- As a manufacturer of special tools, we have achieved domestic production of “traverse-type valve finishers” through our superior manufacturing technology and highly reliable manufacturing.
- In addition, we have developed a unique traverse mechanism to reduce maintenance costs by extending the service life of the traverse, thereby solving problems at the manufacturing site.
- The quick-change elemental technology cultivated in tool manufacturing is incorporated into the valve finisher, contributing to improved usability in tool changing.
