Adopting a fixed crossbeam and mobile worktable structure,the crossbeam has good rigidity and is suitable for high-power cutting.The three-axis drive adopts large-diameter pre stretched ball screws or gear racks(ultra long stroke X-axis),combined with heavy-duty roller guides,with strong load-bearing and impact resistance capabilities.The BT50 large taper hole spindle paired with a high torque motor can perform strong milling of steel,cast iron,and difficult to machine materials.The spindle box is usually equipped with a hydraulic or mechanical loosening knife mechanism and a central water outlet function.The large capacity chain tool magazine meets the needs of multi process machining.The machine tool is equipped with a high flow cooling system and a spiral chip conveyor,which has strong ability to handle iron chips.
The worktable can support a weight of over 5000 kg.The fast movement speed of X/Y/Z axis can reach 20/20/15 m/min.The maximum torque of the spindle can reach over 600 Nm.Machine tools usually use three-axis fully closed-loop grating ruler feedback(Y/Z axis).Numerical control systems often use Fanuc 31i or Siemens 840D.The overall power demand is high,and the main transformer usually requires 80-120 kVA.The appearance is huge,covering an area of up to 10m x 5m,with a net weight of over 25 tons.
Mainly used in the rough machining,semi precision machining,and partial precision machining of heavy machinery,engineering machinery,energy equipment(wind power,hydropower components),rail transit(bogies,vehicle body molds),shipbuilding,large molds(automotive cover parts molds,bumper molds),steel metallurgy spare parts and other fields.Proficient in processing large welded structural components,large castings and forgings,as well as plate parts that require long stroke processing.It is a key production equipment for large manufacturing enterprises.
