Product Description
4 axis design - Experience unparalleled precision and efficiency with our advanced self-centering fixture. This state-of-the-art feature enables one-time clamping, ensuring seamless completion of intricate processing tasks with outstanding accuracy.
Discover the power of our double-end centering machine, a specialized CNC machine tool engineered to perfection for processing the end face and center hole of shaft parts. Boasting the capability for single-time clamping, it excels in executing milling, drilling, tapping, chamfering, and additional processes on both ends of the workpiece simultaneously. This innovation significantly boosts processing efficiency and precision, setting new standards in machining excellence.
Our multi-spindle centering machines are a testament to versatility and functionality, coming in three distinguished types: flat bed, inclined bed, and vertical, categorized by their bed form. Furthermore, in terms of spindle number, they are available as single head, double head, and multi-head configurations, catering to a diverse range of manufacturing needs.
Double-head centering machines are the pinnacle of choice for processing shaft parts across a spectrum of industries including automotive, motorcycle, motors, pump valves, agricultural machinery, and construction machinery. Their application spans the machining of half shafts, cams, E-bolts, and more, utilizing the precision and reliability of a superior milling machine.
Each end of the machine is equipped with milling spindles, drilling spindles, and threading spindles, offering a suite of functions such as chamfering and end cylindrical turning. This versatile setup allows for the same spindle to be used at both ends, or for separate spindles with distinct functions to be deployed, enabling simultaneous processing of both ends of the workpiece. Alternatively, it can perform identical or varied processing operations in sequence, epitomizing the essence of a multifunctional spindle combination CNC machine tool, designed for unmatched versatility and efficiency.
