Cross wedge rolling machine
The machine uses different rolling methods in changing the cross section of the material in focus. The rolling methods used with this machine may include cold, hot or warm cross wedge. Because of these capabilities, the machine can be tailored as per the requirements of the customer depending on the rolling design one is interested in. The various cross wedge rolling techniques operate at different temperatures and the final product dimensions, accuracy and surface smoothness will be different. Hot and warm rolling cross wedge techniques are preferred when dealing with solid materials. The machine is equipped with movable dies (two) which facilitate the use of wedge of 3.5 m in terms of length. With a wedge of 3.5 m in length, the rolling machine can produce up to 200mm diameter of performs.
Other type of rolling machines are Pyramid type rolling machine
This is a plate rolling machine with extended rolls which help in the whole process of rolling. The machine is capable of doing a number of shapes of rolls since it is fitted with a number of dies for rolling at different angles. It is fitted with an attachment which facilitates conical rolling of materials. For stability of the machine, pyramid plate rolling machine has an extra heavy base frame. This is important when rolling as the machine will be firm hence give the required final shapes of materials fed into it. The machine is equipped with other components such as: the shell support device, ejecting device (pneumatic), feeder, gear box and gun metal nuts (helps in rotation). For the machine to work properly and efficiently, it has a speed controller which ensures accuracy in rolling. The whole machine is housed in a steel fabricated structure which guarantees the safety of the machine.
