Dynamic machining allows high feed speeds of up to 30m/minute
in the linear axes with acceleration values up to 3m/s². On the control
side, the user friendly DMG ERGOline control desk with 19 inch
display is utilised and users can choose between Heidenhain iTNC

On the turning front, the third quarter of the year will see DMG
enter the large turn/mill machining centre market with its CTX delta
4000 TC and CTX delta 6000 TC.
With turning lengths of 4,150mm or 6,150mm respectively and a
maximum turning diameter of up to 1,070 mm, the two machines are
particularly suitable for the machining of large shafts. Both machines
are equipped with DMG’s ERGOline control and large 19 inch gripper allows tool change times of less than one second. With nine thereby allowing extreme undercuts. Two optional automation
