The auto-index feature enables a punch and die set to be rotated through 360° under NC control during punch press operation, enabling a large variety of complex shaped products to be made with a minimum number of punches.
Rotating a punch set so that it can be used at many angular settings has the same effect as greatly increasing the number of available punches.
Two auto·index stations per turret greatly increase the versatility of the turret punch press.
The auto-index punch and die are each mounted in worm gears turned by a DC motor.
One DC motor turns both the punch and die simultaneously, assuring perfect alignment and minimum wear.
Some AUTO-INDEX punching examples
All angular holes are cut out by one auto-index punch.
Workpiece size: 85 x 371 mm
A greater variety of products may be made by using a combination of
auto-index punch shapes.
Micro-joints can be programmed to remain even after circular punching. Therefore, it is possible to produce a large number of circular pieces automatically without stopping to remove each one individually.
The auto-index feature makes it possible to cut complex forms from a
single worksheet , considerably reducing the labor of subsequent operations.
Auto-index means a considerable cost saving over the standard nibbling process .
Auto-index can also produce shapes that nibbling cannot .
