In the field of precision machining, the dual demands of efficiency and precision drive the continuous iteration of equipment technology. As the core component of composite machining equipment, the power turret, with its multi process integration capability, has become one of the key technologies to break through the limitations of traditional machining. Compared with traditional tool towers, power tool towers provide active rotational power for cutting tools through built-in drive units, and can complete complex machining such as milling, drilling, and tapping without relying on spindle drive, fundamentally changing the machining boundary of a single device and providing technical support for the integrated manufacturing of precision parts.
The advantages of power turret are particularly significant in the machining of shaft parts. Taking the precision hydraulic valve core as an example, its outer circle accuracy needs to be controlled at the micrometer level, and multiple processes such as outer circle turning, radial hole drilling, and end face milling need to be completed on the same workpiece. In traditional machining mode, workpieces need to be clamped multiple times between lathes, milling machines, and drilling machines, which not only takes a long time but also easily affects accuracy due to positioning errors. The turning and milling composite machine equipped with a power turret can complete all processes with one clamping. With the high-speed tool changing function (usually within 0.5-2 seconds) and precise positioning system of the turret, the errors between processes are controlled within a very small range, greatly improving the machining efficiency and accuracy stability of shaft parts.
In the processing scenarios of disk and irregular parts, the flexibility of the power turret further expands the processing possibilities. For example, the wheel hub of a car gearbox has multiple threaded holes and positioning slots of different specifications distributed on its end face, and high requirements for the positional accuracy of the hole system. The power turret can be equipped with multiple types of cutting tools to quickly switch between turning, milling, tapping and other functions during the machining process, without the need for secondary clamping to complete complex feature machining. At the same time, some power turrets support Y-axis and C-axis linkage, which can achieve milling of spatial surfaces and meet the precision manufacturing needs of irregular structural components in the aerospace industry, such as mortise and tenon processing of engine blades.
In addition, in the precision machining scenarios of small and medium-sized batches with multiple varieties, the flexible production capacity of the power turret effectively reduces production costs and time costs. Traditional production lines require specialized equipment to be configured for different processes, while the power turret can quickly switch processing solutions through software programming, without the need to frequently adjust equipment parameters and fixtures. It is particularly suitable for the processing needs of multiple varieties and small batches of parts in fields such as medical equipment and precision instruments.
With the continuous improvement of processing efficiency and precision requirements in the precision manufacturing industry, the technological iteration of power turret will continue to advance, and its application value in composite processing and flexible manufacturing will be further highlighted, becoming an important technical support for promoting the efficient and integrated development of precision machining.
