Aerospace
Machining of high strength Titanium blades and airfoils call for extremely durable high torque spindles. Besides cost efficient milling of structural aluminum parts require maximum power. Step-Tec spindles are known for their excellent price/ performance ratio, the superb ratio of performance to compactness. In the long run they offer the reliability which gives the cost advantage you are looking for. That’s why Step-Tec spindles are considered first choice for aerospace applications.
