Introduction
Bar straightening machine, also known as a straightening press, is a specialized machine used to straighten and polish metal bars. It is an essential tool in the manufacturing industry where precision and accuracy are crucial to producing quality products. In this article, we will explore what bar straightening machines are and how they work.
How Does a Bar Straightening Machine work?
A bar straightening machine operates by drawing a bar through two or more straightening rolls that apply pressure to bend the bar in the opposite direction to its initial bend. The number of rolls and the pressure applied depends on the specific type of machine being used and the thickness and material of the bar. The straightening rolls are often made of hardened steel and are coated with a layer of chrome to increase the lifespan of the rolls.
