Condition: new, functionality: fully functional, Topking X-25 CNC Cylindrical Grinding Machine Topking “The X-25 CNC cylindrical grinding machine is the perfect answer for UK manufacturers facing space constraints,” explains Simon Rood. “Unlike traditional T-type base designs, the X-Series utilises a revolutionary cross-slide structure. This design allows the X-25 to reduce floor space requirements by over 30% while significantly enhancing stability. It is a superior choice when space is limited, making it ideal for busy production environments where every square metre counts.” Machine overview INTRODUCTION Compact CNC cylindrical grinding machine with an impressive capacity. Fsdpfx Ajubbqienlspk The X series CNC cylindrical grinding machine integrates advanced design and innovative features, offering efficient, precise, and flexible machining solutions. This grinder can meet various processing needs and ensure high-quality results for small or large components. The X-axis and Z-axis of the X-series CNC cylindrical grinding machine adopt a cross-slide design, effectively reducing the footprint and axial travel, thereby saving production space. The high-rigidity machine body and the heavy-duty spindle and tailstock significantly increase the component load capacity. The high rigidity machine body ensures stability during grinding, providing high-quality machining results. The operating system is equipped with a high-performance CNC control system and a built-in graphical user interface (GUI), making setup easy and enabling users to operate with ease. The grinding applications are extensive, offering customers the most suitable machining solutions.
