CNC Double Column Machining Centres

Cosmos Grinding Technologies has introduced the new Sanco Double Column Vertical Machining Centre, Series SDM. The SDM series design is capable of handling heavy hogging on large oversized workpieces and provides the accuracy that is required for aerospace and die mould applications. The SDM series (1700 mm to 7000 mm) offers 1700 mm to 7000 mm travel for X-axis. The standard spindle speed for SDM series is 4,000 RPM with BT-50 spindle taper. The maximum spindle horsepower output is 30 HP with two-speed gearbox transmission for high torque output on 4,000 RPM and optional 6,000 RPM spindle that is needed for heavy metal removal. The SDM series is designed with oversized roller type LM guideways on X- and Y-axis, and hardened and ground boxed ways for Z-axis to provide machining accuracy. The series features a Y-axis design with three roller guideways that enhances the cutting rigidity necessary when the spindle is fully extended to the table. In addition, the headstock is supported by a counter weight system that offers smooth Z-axis movement required for 3D contouring applications. The structure of SDM series is simulated through FEM analysis to achieve optimal rigidity for all machining direction. To help ensure operating efficiency, the SDM series is equipped with double spiral type chip conveyor system to automatically discharge the metal chips to a centralised area.
