Amazing facts!
── Introducing ideas and technologies ──
The “Hobbing Machine Changeover Jig” flexibly handles clamping of various types of workpieces by means of clamp diameter adjustment and centering mechanism.
Furthermore, the diameter can be adjusted simply by turning the diameter adjustment ring without the need to replace any parts, enabling quick and easy setup work.
This contributes to “investment reduction” and “reduction of setup man-hours”.
Investment reduction
Good!
Conventional method requires a separate jig for each workpiece (total 4 set, each sized to ø106, ø109, ø121, ø124 mm)
Hobbing Machine Changeover Jig is compatible with all workpieces (total 1 set for ø106~124 mm).
*Dimensions in parentheses indicate the inside diameter of the workpiece.
Reduced changeover man-hours
Good!
In fact, there is no need to change any jigs.
This is the point!
Easy and quick changeover:
No need for extensive jig replacement work!
Excellent!

Return upper jig then center and clamp
Development / product concept
“Current status and challenges”
- Normally, the hobbing machine requires a jig change for each workpiece type, which takes time to change stages. In addition, the need to prepare a jig for each type of workpiece results in a large cost.
“Development points”
- The “hobbing machine step change jig” has variable workpiece centering, and the clamp diameter can be adjusted with the clamp diameter adjustment mechanism ring. It contributes to investment reduction and man-hour reduction in setup.
