The machines include a mobile column that is horizontally fitted on the Z axis to provide force induction. Wide linear guides in the linear axes are said to provide rigidity and stability. For precision, the machines feature linear scales in all slide axes as well as a thermo-symmetric design and active cooling of the main spindle, the optional coutnerspindle, motor consoles and the turning/milling spindle.
The turning/milling spindle features an NC-controlled B-axis that can swivel to ±100 degrees, enabling simultaneous five-axis milling. The main spindle can achieve rotational speeds of 12,000 rpm, while the optional counterspindle is capable of 18,000 rpm. The company’s Ergoline control unit features a 19" screen for enhanced reading comfort and a swivel mechanism that allows operators to adjust the screen and the operating panel. The large screen also accommodates the company’s customizable “Softkeys” to which users can assign operation sequences. The controls are available with either Siemens’ 840D solutionline with ShopTurn or the Heidenhain’s Plus iT with DinPlus (and TurnPlus as an option).
Editor PickWhen a Turn-Mill Doesn’t Turn
LeanWerks uses innovative probing, tooling and workholding strategies to enable its turn-mill to machine castings complete, in effect turning it into a five-axis machining center.
