DETAILS OF FINGERS FOR STANDARD EXECUTION :
 
 
Leaf type presicion bending brakes corresponds in principle to large mechanical driven bending brakes and performs various Forming and Duplicating operations in experimental and production quantities. Even very small jobs such as making of closed boxes and chassis for apparatus radio cabinet parts. which is possible with versatile possiblites of the finger combinations.
 
 
It consists mainly of a frame of robust construction and a bending beam precisely supported on either side and provided with operating handles. There is top beam with hardened with hardened steel adjustable fingers, a clamp for securing the sheet and measuring thickness and also an adjustable gauge to measure angle of bending.
 
 
[a]
A set of 11 fingers, high-grade alloyed steel, hardened and ground, for a bending range from 10 to 610mm, in increments of 5mm.
