How to measure whether the stability performance of a fiber laser cutting machine is good is a question that many buyers are concerned about. The common fiber laser cutting machines on the market are mainly composed of mainframes, guide rails, gear racks or ball screws, transmission mechanisms and other components. Let's make a simple analysis of these components.

The mainframe consists of a crossbeam and two longitudinal end frames. The machine gantry of the fiber laser cutting machine consists of an end frame and a crossbeam. The crossbeam adopts a rectangular square tube structure, tempered to remove internal stress, and has high strength and rigidity. Multiple mobile trolleys can be installed on the crossbeam. The horizontal moving devices all use drag chains. The mechanical part realizes high-precision gear rack transmission, and the guide rails are made of high-precision special imported guide rails. The precision-machined sliding guide rails are fastened to the concrete or steel frame foundation with a support, and are equipped with adjustment bolts for installation and adjustment. The longitudinal drive system is installed in the longitudinal end frame, and the low-position design makes the transmission more reasonable and stable.

There are two front and rear rolling wheels at the bottom of the longitudinal end frame, which can roll smoothly along the guide rail. The front and rear ends are equipped with guide rail scrapers to ensure that there is no debris on the surface of the guide rail. Eccentric clamping wheels with guiding functions are installed on both sides of the bottom. To ensure the guiding accuracy of the machine, the fiber laser cutting machine is equipped with high-strength linear guide rails (horizontal transmission or high-precision fine grinding guide rails) in the horizontal transmission and cutting torch lifting. The precision-machined gears and racks ensure the longitudinal and lateral transmission accuracy of the machine and eliminate the gap.
