High Productivity Turning Center Doosan Machine Tools Optimal Solutions for the Future

High Productivity Turning Center The Lynx 220 series is a accurate, high productivity turning center designed with ultra fast rapids and high-speed turret indexing providing greater value and cost performance.

High Speed Structure Max. turning dia. X length • Core machine Lynx 220 The heavily ribbed torque tube design prevents twisting and deformation. All guideways are wide wrap-around rectangular type for unsurpassed long-term rigidity and accuracy. FEM analysis used to design a stable body. ( FEM : Finite Element Method ) Rapid Traverse Roller-type LM Guide is mounted on the machine to improve rigidity and feedrates. Each axis is powered by a maintenance free digital AC servo motor. These high torque drive motors are connected to the ball screws without intermediate gears for quiet and responsive...

Main Spindle The C-axis is positioned in degree increments of 0.001. Through spindle synchronization with the X and Z axes, three dimensional contouring, complex and prismatic machining can be accomplished. Headstock and spindle The headstock and main spindle are manufactured in a temperature controlled environment then assembled and tested in our clean room. The heavy duty cartridge type spindle is supported by a triple row angular ball bearing in the front, with a row cylindrical roller bearing in the rear. This combination of bearings is very effective in refraining from thermal displacement...
