subject: Various Features Of Roll Benders And Cnc Milling Machines [print this page] In this article, we will discuss how roll bending machines and CNC milling machines are present in the mechanical workshop. Roll benders used as the mechanical jigs, which come equipped with three rollers used to shape up any metal bar into a circular arc. These rollers rotate freely about three parallel axes, which are aligned with uniform horizontal spacing. Two outer portions of the rollers have the same fixed vertical height. And, they are connected with the underside of the formed bar. This kind of middle roller comes with an adjustable height. Then, it gets aligned with the topside of the bar.
As long as metal fabrication is concerned, roll bending machines are there to convert raw pieces of metal into desired shapes and sizes. In the machine shops, we might see the existence of angle roll benders. This kind of bending machine is made in a vertical steel frame. In that case, bending portion of the machine is situated on one side, with the power and drive of the machine on the opposite side. Use of the roll bending machine is seen for bending tube and pipe to large circumferences. This kind of bending machine is usually used for any round items with the large center line Dia. Examples of such machines would be Chopper frames and handle bars.
Any milling machine is that machine tool, which is used to machine solid materials. There are two common types of milling machines seen in the workshop and they are horizontal and vertical. Both types of machines are found in different sizes from small, room-sized machines to bench-mounted devices. Any milling machine is helpful in moving any work piece radially against the milling cutter. After that, cutting on each side as well as tip of the metal takes place. Work piece and cutter movement would be controlled to less than 0.001 in (0.025mm), which is usually by means of lead screws, precision ground slides or analogous technology. Milling machines are either found in manually operated option or in mechanically automated way. These days, we can also see the presence of CNC milling machines, which are digitally automated via computer numerical control.
Performance of milling machines can be seen in various numbers of operations. They are used for simple operations like, slot, keyway cutting, drilling, planning etc. Also, they are utilized for the complex task like, contouring, die sinking etc. Mill orientation is found to be the basic classification for the milling machines.
