What is Backlash in CNC Machining and How Can You Avoid It?
Backlash is the tiny clearance available between adjoining gear teeth. This space exists to avoid the machine from jamming and allow easy lubrication. Nevertheless, while machining, this space can cause the measurement to be inaccurate and the design to be unresponsive. So, backlash is both necessary and a problem. In CNC machining , backlash is especially problematic as it can be difficult to trace and even more difficult to compensate. Sometimes the clearance between adjoining gear teeth is not the only reason for backlash. Backlash can also be caused by loose and deformed machine parts. One of the most common and best ways to solve backlash issues is to replace the lead screws with ball screws. Ball screws are more suited for CNC machining as they provide smooth operation, efficiency, accuracy, speed, precision, and long-lasting high-speed movement. You can also reduce the amount of backlash by compensating for it. If you are a manual machinist, you can compensate for it by fee...
