In recent years, the application of horizontal turning and milling composite technology has become increasingly powerful in China. Locomotive, water conservancy, mining, shipbuilding, power generation and other enterprises urgently need large-scale horizontal milling composite technology. Today's standard will analyze the characteristics of this large-scale horizontal turning and milling composite processing technology.
1. Overall layout
The large horizontal turning and milling composite machine adopts a design of side hanging single column, inclined bed body, and double main axle box. The machine has a double knife rest structure on both sides of the lifting box, allowing the props to be used in the direction of gravity. Moreover, this large horizontal turning and milling composite machine is specially equipped with electrical devices, workpiece detection, protection devices, tool detection, chip removal devices, tool magazine water cooling devices, and constant temperature cooling devices.
2. Technical parameters
Horizontal turning and milling composite machine tools have obvious advantages in torque output, load-bearing capacity, power, and other aspects. It breaks the current layout where overseas car milling composite centers can only be equipped with a single tool holder. The large-diameter cutting head is equipped next to the right tool holder, which can complete all precision and rough machining on one machine, making operation more convenient. Moreover, the left tool holder of the horizontal turning and milling composite machine is combined with the function of the main spindle C-axis, perfectly achieving five axis linkage.
3. Technological innovation
1. Single column technology
Although the horizontal turning and milling composite machine tool is equipped with a double tool holder, the overall layout of the machine tool is still very compact. They adopt a single column shape, inclined at a 30 degree angle, and are suspended on the ground auxiliary guide rails and bed of horizontal milling composite materials. This can effectively reduce the weight of the machine tool while ensuring the smooth movement of the machine column, reducing the processing cost and the required amount of raw materials.
2. B-axis tool holder technology
Traditional turning and milling machines are usually equipped with very single tool holders. They install the turning tool and the rotating tool together in the same position inside the B-axis tool holder of the machine tool, and there is a special three tooth disc at the top that can be used to lock the turning tool. This can make the suspension of the power shaft longer and reduce its stiffness. However, one drawback is that the machine is no longer suitable for rough machining and only allows precision machining.
