Vol.4 FORMING TOOL

Not only punching but also various forming processes are possible with the NC turret punch press.

Forming process for making tubes of threading for screw.

〔 Forming up 〕

〔 Forming down 〕

There are two types of tooling.

Die which performs pre-hole processing and burring at the same time.

Die for burring after pre-hole processing

〔 FORMING DOWN 〕

(Pre-piercing and forming)

〔 FORMING UP 〕

(Forming after Pre-piercing)

〔 FORMING UP 〕

(Pre-piercing and forming)

Our standard dimension table
(other than upward & downward hole one process type)

〔 Forming up 〕

〔 Forming down 〕

・The standard is a height adjustment free type.
(a die that required punch length adjustment for each plate thickness.)
・Standard center punch angle is 90 degree.
Please specify if an angle other than 90 degree is desired.
・The depth of the center point is optionally adjustable.

※We also produce a type that adjusts and fixes the punch length for each material thickness.
