ST-SeriesST-Series
The specialized machine for continuous fabrication of domed cap nuts and bottomed nuts.
Ready made Tapping unit is mounted. In case that the servo type is selected, parameters such as stroke setting can be set as digital values.
The work holding mechanism to be used during automatic conveying and screw cutting is designed for the respective works.
A straight tap (but limited to the form rolling tap) that is available in the market is used.
The automatic conveying is carried out by rotating the index table. In case of work holding with a collet chuck, there are four stations divided by 90 degree each. In case of work holding with a rotation stopping hexagonal guide, the machine has six stations divided by 60 degree each.
