Steinmeyer Declared New Decoupling Composing

Steinmeyer declared an innovative, outlay strong decoupling arranging for ball screw drives that enables our criterional PMT 160 serial stages to reach brainstorm execution - namely honestness and matt runout of 50 nanometers or inferior! The decoupling group isolates any thwartwise movement of the ball screw from the rectilineal bearing system and notch of the platform.

The application of decoupling devices is prescriptive in all ball screw driven PMT 160 playoff stages from Steinmeyer. The PMT 160 offers travels from 50 mm to 300 mm, with criterional positioning accuracy of lower than 10 µm and repeatability of ±0.5 µm when unvoluntary by either dc servomotor (with cyclic encoder) or dc dancer travel. Higher accuracies are thinkable finished the use of linelike encoders.

Level though the linear bearings in Steinmeyer's exactitude stages are dramatically oversized, their stiffness is not infinitive. Fight forces can elastically change supposition scale, bearing and saddle and interact in the characteristic and dimensionality of the undivided leg system. By applying flexure designs shaft celebrated in piezo micropositioning stages, Steinmeyer mature a set that virtually eliminates these personalty!

The Steinmeyer gather is comprised of two manufacturing divisions situated in Frg. Venerable Steinmeyer GmbH & Co. KG  has been mounting standards for intoxicated exactness ball screws for over 40 period and prides itself on piping propertied, original designs to fulfill exigent consumer requirements.
