Experience unparalleled precision and efficiency with our Double-Sided CNC End Face Milling and Centering Machine, now enhanced with advanced Hole Tapping capabilities. Engineered for excellence, this machine delivers superior performance in every milling and centering task, ensuring your operations are both seamless and highly productive.
Product Description
4-Axis Design - Featuring a remarkable self-centering fixture that allows a single clamp to efficiently complete the entire processing sequence, this advanced design ensures precision and saves you valuable time.
The double-end centering machine is a specialized CNC marvel engineered for the meticulous processing of the end face and center hole of shaft parts. With one-time clamping, it performs milling, drilling, tapping, chamfering, and more on both ends of the workpiece concurrently. This remarkable functionality enhances processing efficiency and precision to new levels.
Multi-spindle centering machines are categorized into three distinct types based on the bed's form: flat bed, inclined bed, and vertical. According to spindle count, they can be classified into single head, double head, and multi-head configurations, each tailored for specific manufacturing needs.
Double-head centering machines have become indispensable in industries like automotive, motorcycle, motor manufacturing, pump valves, agricultural and construction machinery. They adeptly handle shaft part processing, such as half shafts, cams, and E-bolts, utilizing advanced milling technology.
At both ends of the machine, powerful milling, drilling, and threading spindles are employed, complemented by capabilities like chamfering and end cylindrical turning. The same spindle can be utilized on both ends, or distinct spindles can be independently assigned, allowing for simultaneous or sequential processing. This state-of-the-art multi-functional spindle combination CNC machine tool sets a new benchmark in versatility.
