With the development requirements of laser processing applications to high speed, high speed and high stability and the improvement of control technology, many people will choose laser cutting equipment for cutting metal materials at present. Its high efficiency, material saving and simple operation are the necessary models for many processing industries. For people who have just contacted the fiber laser cutting machine, how should they choose whether the fiber laser cutting machine is better driven by one side or by two sides? Xinquanli Laser will analyze with you.
When driven by double-sided gear and rack, the rack length of the fiber laser cutting machine can be connected and extended indefinitely, and the width of the machine tool can be expanded to meet the needs of non-standard customers. The single drive is driven by a motor.
The gear rack of fiber laser cutting machine is divided into straight teeth and helical teeth. Compared with straight teeth, helical teeth have larger meshing area, and the transmission between gear and rack will be more stable; They will have their own motion characteristics in the transmission process: gear transmission is used to transmit the motion and power between any two shafts, and the transmission power is large, which is the characteristics of gear transmission. The gear rack has a longer service life than the screw nut when driven bilaterally, with stable operation, high reliability, strong driving force and high speed, which can give full play to the high-speed characteristics of the fiber laser.
When driving on both sides, there is a motor at both ends, which can accelerate the start faster in a short time and achieve high-speed movement. It is conceivable that, on the premise of ensuring the synchronization of the two motors of the left and right guide rails, the dual-drive drive starts faster than the single-drive drive drive in terms of idle speed, cutting speed and acceleration. In this way, for laser metal cutting application manufacturers, the purchase of metal laser cutting machine with dual-drive drive can achieve greater output value and higher efficiency in the same time, so the dual-drive cutting method is more advanced.
The laser cutting machine with gantry structure has two types of motion: one is that the gantry moves but the workbench is fixed during processing, and the other is that the gantry is fixed and the workbench is moving. For large-format, high-speed and high-performance laser cutting machines, the first form is usually used, because the worktable moving with the workpiece is not suitable for high-speed and thick plate cutting. Bilateral drive is used to ensure that the force of the beam is balanced and the beam runs synchronously. The laser cutting machine of some manufacturers adopts the single-side drive of the gantry. The servo motor is installed at one end of the gantry beam, and then transmits the driving force to the other end through a long shaft to realize the double-tooth gear rack drive and single-servo motor drive. Unilateral drive makes the force on both ends of the beam asymmetric, which affects the synchronization accuracy and reduces the dynamic performance of the machine tool.
So how to choose in the purchase process should be clear to everyone at a glance. Of course, investment is also a consideration, or you don’t need to wait. After all, what suits you is good.
