Amazing facts!
── Introducing ideas and technologies ──
The G-one holder consists of multiple roughing and finishing edges.
By dividing the role of each cutting edge function and using a single finishing edge with standard inserts, the G-one holder reduces setting time compared with conventional products and does not rely on the skill of the operator.
High productivity, high-precision machining and reduced costs are achieved.
Reduced setup time
Good!
Cost reduction
Good!
This is the point!
The role of the cutting edge is divided by function
Excellent!
Development / product concept
“Current status and challenges”
- In high-precision hole drilling of aluminium workpieces, ‘one-shot machining’ from the material hole by using multi-edge tools has been established with the aim of increasing cycle time through process reduction from conventional rough and finish machining.
- However, new issues have to be addressed at the production site, such as long cutting edge setup time due to multi-edge machining, unstable machining accuracy due to edge run-out, and high costs for special inserts.
“Development points”
- The “G-one holder” solves these problems by integrating multiple cutting edges with different roles and properties into a single holder, and also achieves high accuracy, high efficiency and low cost, comparable to conventional machining.
