Ins and Outs of Linear Rail Systems for CNC Machines
Mar 21, 2017When working with CNC machines that require significant movement along the X and Y-axes, the usage of linear rail devices can help to facilitate that movement. Learn more about these vital elements of CNC machining.
How Does a Linear Rail System Work?
While their job may initially appear to be insignificant, linear rails perform an essential role in the performance of automated machining. When combined with a gantry, these tracks make up a support system that can carry computerized cutting devices both horizontally and vertically. One of the most important functions of these slide features is to allow the proper amount of friction for the machine to travel freely. In automated machinery, inertia is controlled by the automated programming. These rails not only provide CNC machines with a measured path to travel but are also vital to supporting secondary functions such as torque or lateral loads.
Components of a Linear System
Depending on the size or complexity of the CNC machine, a linear rail may use either ball bearings or roller slides to move the length of the rail. For larger systems, roller slides are typically preferred for added strength and to reduce the price of a ball bearing system. However, if the slides associated with this form of motion system are not appropriate for the CNC machine, using these systems can be counterproductive.
Why Are Rail Systems Useful?
In short, without the use of a linear rail system, CNC machines would have no path for movement. A properly functioning linear system is firmly affixed in place. If a rail system is improperly installed, it will impair the ability of the machine to travel as directed on the path. Ensuring the proper motion system not only allows a system to perform an ordered task, but it can also save money associated with repair costs for both damaged machines and rail systems.
The increasing reliance of manufacturers on automated technology means that more companies are utilizing these types of machines. Linear movement systems are not only important for smaller projects but are also essential for the construction of larger products such as airplane wings and boat hulls.
