Vertical CNC lifting table milling machines, as a rare medium and large-sized product in the domestic market, have occupied a place in the market with its advanced performance, compact footprint and superior cost performance. The machine adopts a vertical milling head design, integrating mechatronics and three-coordinate linkage functions, and can provide fourth-axis control according to user needs. Its strong load capacity, excellent specifications and high-rigidity structure make it stand out among similar products. The domestic market demand is strong and the development potential is huge.
Core technology and design
The core technology of the machine tool lies in its feed system. The feed of the three coordinate axes X, Y and Z is precisely driven by AC servo motors. Through the ingenious combination of synchronous toothed belts and ball screws, the components can move smoothly along the guide rails, and the tensioning design of the synchronous toothed belt effectively reduces the transmission gap. The three-way feed is driven by ball screws and servo motors to ensure high-precision transmission effects. In addition, the strength and rigidity of the machine tool have also been carefully designed. The guide rail pair has been quenched and equipped with plastic coating, which ensures high precision retention and long service life. The application of 18-level spindle speed change function and hole-disc centralized speed change mechanism further broadens the speed change range and makes operation more convenient. The spindle adopts cycloid pump for centralized lubrication, while the feed drive adopts damping automatic lubrication to ensure the durability of the machine tool. The split design of the control panel and the motor cabinet, as well as the free rotation angle function of the cantilever control panel, greatly facilitate the use of operators. It is particularly worth mentioning that the large lead ball screw design adopted by the X-axis of the workbench enables the workbench to reduce the screw speed when moving at high speed, thereby effectively controlling the temperature rise and noise problems.
