A CNC bender is a machine used to bend metal and other materials with high precision. The term "CNC" stands for "Computer Numerical Control," which means the machine is operated by a computer program. This allows for consistent and accurate bends, making it ideal for manufacturing parts in various industries, such as automotive and aerospace. CNC benders can handle different types of materials, including steel, aluminum, and copper. They are equipped with various tools and dies to create specific shapes and angles. The automation of the bending process reduces human error and increases efficiency, making it a valuable asset in modern fabrication shops.
