In the design of large-scale CNC cutting machine equipment, in order to improve transmission efficiency and cutting accuracy, bilateral drive design is generally adopted as a solution. For example, the familiar gantry CNC cutting machine is generally designed with three groups of motors, of which two groups of motors in the longitudinal direction provide bidirectional drive for the gantry CNC cutting machine. This paper is edited by xxxxxxxxxxx Technology Production Department, and mainly summarizes the synchronization accuracy and characteristics of bilateral drive CNC cutting machines.
First, the performance advantages of bilateral drive CNC cutting machine
In the design of two main motion forms of CNC cutting machine, one is gantry moving and table fixing during machining, and the other is gantry fixing and table moving. For CNC cutting machines with large format, high speed and high performance, the first form is often adopted, because the workbench moves with the workpiece and is not suitable for cutting high-speed thick plates. The SF Xunfeng series CNC cutting machine of Baike Technology is the first type, which adopts double-side drive, that is, racks and servo motors are symmetrically installed on both sides of the gantry beam to realize double rack-and-pinion drive and double servo motor drive. Two-way drive ensures that the beam is balanced and the beam runs synchronously. However, some other manufacturers' CNC cutting machines adopt gantry single-side drive, and the servo motor is installed at one end of the gantry beam, and then the driving force is transmitted to the other end through the long shaft, thus realizing double rack-and-pinion 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.
Second, the synchronization accuracy of bidirectional driving CNC cutting machine
The synchronization of bilateral drive affects the speed, acceleration, positioning accuracy and stability of the beam of NC cutting machine. SF series CNC cutting machine adopts the patented third-generation CNC system independently developed by the company, and the servo motors driven on both sides have encoders to realize speed and position control. The core of the system has special synchronous control function, and both servo motors have accurate zero position. At the same time, after returning to the reference point, taking the double zero position as the starting point of synchronization has higher accuracy. Double servo motors complete the synchronous control of speed and position in the position control cycle, and there is no distinction between master and slave, so it is completely synchronous and undifferentiated.
The accuracy of bidirectional drive directly determines the positioning accuracy of the beam axis of NC cutting machine, and will affect the synchronization of bidirectional drive. Although the servo motor and rack and pinion of bidirectional transmission are of the same specification, the mechanical error of bidirectional transmission is inevitable when the beam shaft of NC cutting machine moves in a long stroke. The unique synchronous control technology of CNC system can compensate the position of both sides of synchronous control, eliminate the mechanical error of bilateral transmission, and ensure the positioning accuracy of the beam shaft of CNC cutting machine in the whole width.
