When bending action is treated to any metal plate then the inner side of metal compressed and the outer side expand a little bit. So bending allowances and bend deduction are the most important factors we have to take care up, while performing bending of the metal plates. When it comes to the bending of metal plates to be used in aircraft wing then the task is completed by the wing edge roll bending machine. This machine is composed of 3 supported rolls, vertical top roll movement and individual, horizontal bottom roll movement. High precision aircraft parts can be bent using symmetrical and asymmetrical roll positions. Roll positioning is spindle-driven for the improvement in precision.

Advantages of a wing edge roll bending machine are:

•Very narrow bending geometry and precise roll positioning allows a great spring back control on thin, hard work pieces.
•All three roll feature rotation derives which can be disabling for press-bending.
•High allow roll with hardened surface are standard. Smooth surface of stainless roll materials upon request.
•Large range of movement on top roll for easy removal of complex of complex work pieces.

Screw Press – A Very Handy Tool for the Forging Industry

Earlier, people were using the screw pressing machine in different ways. But nowadays this machine is used to derive the force up and down by a screw. A wheel is attached to the shaft for operating this. As there is no jerk or shock formation, therefore this screw press machine does not require any special type of foundation to operate. This performs acclamation from 10 to 40 per minute and can create pressure up to 25 to 1800 tons.
