![]() Our machines built with large linear guide rails and bearings help reduce maintenance and wear compared to smaller bearing systems. The design also effectively makes the machine a self-cleaning system, reducing the need to wipe down rails or watch for buildup both during and after operation. The wipers extend the bearing life and performance. ![]() The triple-sealed bearing blocks help ensure that debris and dust buildup on the rails do not lead to pre-mature failure, while it’s still important to perform normal housekeeping. The use of two bearing blocks on each rail ensure the cut forces are equally distributed over the rail to reduce the amount of wear and noise. ShopSabre’s machines utilize 25mm linear guide rails with triple-wiper linear guide bearing blocks. ShopSabre’s use of precision contour guide rails Linear guide rails allow everything to be predictable so users can incorporate engineering software to help in the design process. This is what drives the increased precision of these machines while minimizing play and backlash during operation.īecause contact between the rail and bearing track is fairly limited, the machine can acc and dec rapidly and achieve increased productivity on small- and large-scale projects. Within the system, recirculating ball bearings connect the rail and the bearing truck, similar to how ball screw technology works. The precision contour guide rail system is really based on two components – the rail and the bearing track – but no component is more critical than the ball bearing. The solution was precision contour guide rails. Manufacturers began using structural steel for machine design, which was very predictable in its characteristics and thus helped open the door for computer design as a means of engineering different components.īecause of this, manufacturers also had to create a compatible guide rail system that would maintain rigidity while allowing rapid acc and dec. The industry had reached its speed limitations in terms of acceleration and deceleration (acc and dec). Then high-speed machining arrived, and none of these previous technologies were able to get the job done effectively. This concept was later developed into round bars, which worked well but were unable to handle heavy loads or to perform heavy machining – which is particularly relevant in the metalworking industry where the weight of certain components for machine frames and more resulted in the use of ground square rails. The evolution of guide railsĪxis motion is an essential concept of machine tool design, wherein the machine moves along the x, y, or z-axis as defined by the guide rail system.Įarly on, guide rails were fairly simple and had a v-guide and a roller that only moved back and forth. Here is a look at the evolution of guide rails and how the precision contour guide rail system helps CNC operators achieve a more precise and efficient process on every project. I would like to thank Openbuilds for fulfilling my special request to cut the C-beam, I was not expecting it and it made completing my project soo m uch easier.CNC technology has come a long way over the last few decades, with constant industry advancements shifting the way work is done and expanding the scope of what is possible in the shop.Īmong these advancements is the development of linear guide rails (also known as precision contour guide rails), which opened a whole new door to the world of high-speed machining. ![]() The C-beam Linear Rails were exactly as expected. You got my business for CNC builds! I am going to order more rails and an x32 soon. I got everything individually wrapped and protected, rails look great and clean. Posted by Raymond Lopez / RaysFabShop on YouTube on Feb 26th 2023 It works great and Openbuilds makes assembling the machine easy. I used this on my 48 X 96 CNC router that was designed by Bor Designs using Openbuilds components. So happy as they were large pieces 1.5m long and delivery was to Christchurch, New Zealand! Arrived very well wrapped and looks to be in fine condition.
