Optical fiber laser cutting machine is a very popular type of processing equipment in sheet metal processing. It not only has high flexibility, but also has high precision cutting quality. It is a sheet metal blanking and forming equipment. Of course, the thickness of cutting sheet metal is different, and the power used is also different. Now, the kilowatt fiber laser cutting machine has become the hot object.
As we all know, the positioning of the fiber laser cutting machine is also quite wide, the configuration is also different, and the price span is also quite large, but in fact, a fiber laser cutting machine has some similarities: it adopts a gantry double-drive drive drive. So what are the advantages of adopting this drive?
Gantry double drive means that both sides of the gantry beam are symmetrically installed with gear rack and servo motor to realize double gear rack drive and double servo motor drive. Bilateral drive ensures that the force of the beam is balanced and the beam runs synchronously. However, some laser cutting machines from other manufacturers adopt gantry single-side drive. The servo motor is installed at one end of the gantry beam, and then the driving force is transmitted to the other end through a long shaft to realize 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.
1、 The double-sided drive of gear and rack has its 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.
2、 When the gear and rack are driven bilaterally, the service life of the gear and rack is longer than that of the screw nut, and the work is stable and reliable.
3、 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.
4、 When driving on both sides, there is a motor at both ends, which can accelerate the start faster in a short time and achieve a high-speed movement.
