Improved shape precision of block punches

The shape precision standards for block bunches were modified in 2007 in order to meet the needs of higher precision dies.In addition, several types of shape tolerance standards are available to suit different customer applications. (These are selected by alterations.)

1)Shape precision standards
Item Standard
Perpendicularity a≤0.005
Parallelism b≤0.005
Warpage c≤0.005
Bending of tip d≤0.01
Perpendicularity of top face e≤0.005

2)Variations of shape tolerances(alterations)
Code None VKC VKM VHM VHZ
Shape tolerance V·H V·H V·H V·H V·H±0.005

Jector punch spring change(Alteration JVC)

Spring reinforced jector punches have been added to the block punch product lineup.
The spring constant is twice that of a conventional jector punch, providing improved scrap removal effects.

Applicable products: All jector punches
Can be used with L≥60.
Cannot be used for H6(With a jector straight punch, cannot be used for W≤6.00.)

How to order
The tip position can be set freely within the range of shank V and H.

Key groove position and flange position can be set freely.(For types with flange thickness of 10mm, the positions are fixed.)

With key groove Single flange·flange stopper Double flanges
  • By default, the key groove, head, and flange are located at the standard positions(0). The positions can be changed at no charge.

Corner radius of square shape type

  • By default, the corners are rounded to 0.2 or less. If R0 is needed, specify R=0.
    R=0 cannot be selected with WPC treatment or HW coating types.
