First of all, after obtaining the model and configuration of the CNC cutting machine , the user will focus on examining and determining the composition, manufacturing quality and price of the CNC machine tool part. The composition and manufacturing quality of the machine tool parts, including the processing and selection of key components such as rack guides, rack and pinion gears, reduction gearboxes, servo systems, pneumatic systems, and height adjustment systems, as well as machine installation grounding and shielding technologies The quality and cost of the machine tool part of the CNC cutting machine determine the service life, cutting quality and cutting accuracy of the CNC cutting machine. At the same time, it also determines the main prices for the purchase and sales of CNC cutting machines.
Finally, on the basis of a certain understanding of the meaning and role of the transmission system composition, we return to the main point of the article, how will the transmission composition of the CNC cutting machine reflect the final price positioning?
1. Gantry CNC cutting machine changes the output of high speed torque servo motor to the input of actuator with low speed and high torque;
2. Gantry CNC cutting machine makes the rolling inertia of the ball screw and the table a smaller specific gravity in the system. In order to minimize the influence of the tooth side clearance on the machining accuracy of CNC machine tools, the gantry CNC cutting machine often adopts structural measures to reduce or eliminate the idle travel error of the gear pair. Such as the use of two-piece gear staggered method, the use of eccentric sleeves to adjust the center distance of the gear pair or the use of axial shim adjustment to eliminate gear backlash, so that mechanical operation and machine cutting can achieve better results!
From the analysis of the above two points, we can judge that the selection of the CNC cutting machine of the gear transmission system has its meaning. In addition, from the perspective of the overall structure, the main advantages of the dual-axis driving CNC cutting machine are reflected in the following three aspects:
1. Suppress vibration at high speed;
2. Improve system rigidity and extend screw life;
3. Improve system response.
In general, the dual-axis drive CNC cutting machine tools are usually used to obtain larger load capacity or for large-span loading and unloading systems, so the main demand in use is not focused on high-speed cutting. However, with the development of related technologies, the speed and precision required by machine tools have continued to increase, and the design of dual-axis drives has also begun to be applied to high-speed machining centers to suppress vibrations caused by high-speed feed.
So the price of different configurations is different. Here Texas Dean NC recommends that when purchasing CNC cutting machine equipment, it is best to directly consult the manufacturer's technical staff for detailed understanding and comparison, so as not to cause unnecessary losses!
