The bending machine has high precision end part prebending, can freely set side length, put high precision end part prebending into practice under certain pressure. The machine has supergroup products precision, and it gains from continuously bending and high precision end part prebending; Besides, upper roller appears drum type, carrier roller coordinates with regulation, can produce ideal products in the extensive scope of sheet and thick board.

There are lavish bending type, such as O type, U type, multiple stage R type and so on, its methods are:

First, O type bending: Back bending

Second, U type bending: Front bending

Third, special bending: Combined type

According to the usage, there are following control methods:

TNC (upper NC): Used for many variety and small amount production

T & BNC (up and down NC0) : Used for less variety and large amount production

CNC(CNC) Used for many variety and large amount production

CNC controlling, high efficiency, one man operation, simple operation, efficiency is raised drastically.
