Tools make all the difference when you’re fabricating metal. Just ask any custom metal fabricator or business that specializes in industrial metal cutting. EZ Cut CNC understands how important it is to have tools that work for you. That is why we have picked the best components possible for our CNC plasma cutting systems. With over 20 years of experience in the CNC plasma cutting field, EZ Cut CNC has developed a product based on practical knowledge that meets the demands of a metal fabrication environment.
The EZ Cut CNC plasma table has spot-on accuracy and seamless motion thanks to every individual component. The drive system, gantry, and side rails have been built to create a torch positional accuracy of just 0.001”. 911 Custom, an emergency vehicle outfitter in Kansas City, owns an EZ Cut CNC 4’x8′ system. Their owner, Jarod Busch, talked to us about the zero backlash motion. “If there is a machine out there that moves smoother, I couldn’t find it in any video,” he told us. “And, if there is a machine that moves smoother, it can’t be by much.”
NEMA 23, 2-phase motors power the X, XX, Y, and Z axis. It’s essential to have the gantry square on the side rails for accurate cutting. Electronic proximity optical sensors ensure that the table boundaries are set and the table is square. A machined billet aluminum gear with a high quality urethane belt, reinforced by a steel cable, is located on the inside of the gearbox. These gearboxes are located on the X and XX axis and are protected by the end trucks.
When looking at the end trucks it’s clear to see the high quality design. The end truck body is made of custom cast aluminum in a machine shop. This construction allows for minimal vibration and improved results when cutting. Extruded aluminum is used for the gantry and side rails. The extrusion process, which uses a custom dye for precise replication, results in a perfect alignment.
The pinions and gear rack are also critical to a smooth running drive system. These parts drive the end trucks along the side rails (X and XX axis), the carriage along the gantry (Y axis), and the torch lifter up and down on the Z-axis. On each axis, quad V-groove bearings move along an inverted V-guide. This set-up features an intelligent design for extremely smooth motion by sweeping debris aside during operation.
When shopping for a CNC plasma cutting system it’s important to look at the parts that make up the system. We refer to these parts as our “Value Components” and we advise to carefully compare each CNC table you’re considering. After all, these parts and the design in which their put together determine how well the system will cut and how it will hold up in a fabrication shop.
