Just like a worktable or workbench, a CNC router needs a surface on which to place sheet goods or lumber stock and a way to hold those materials in place when they are being machined.



Linear guide rail system: weighing pros and cons

Written by R.W. Lee Monday, 20 October 2014 00:00

My previous two articles covered the two major sub-assemblies of a CNC machine: stepper and servo motors, and linear drive systems. Our tour is almost complete with a description of the linear constraint systems. This term is used to describe the structure or frame of the machine and the linear guide system, which is attached to the frame and allows movement of the machine’s axes.
