🔬 The error is measured at the optics. The ball screw is part of the equation. In wafer and chip inspection, the XY stage moves a chip through a defined scan pattern beneath a measurement microscope, repositioning multiple times per session. The video shows a KT470 cross table from Steinmeyer Mechatronik GmbH driven by our miniature ball screws, performing exactly this motion. The KT470 is available in two configurations: ➡️DC motor version with linear measurement system ➡️ stepper motor version in open loop The first achieves ±0.5 µm unidirectional repeatability across 300 × 300 mm of travel. The second reaches ±2.3 µm. Different performance levels, built on the same mechanical platform. The ball screw is identical in both. Its role is not to define which performance level the system reaches — that is determined by the motor and feedback architecture surrounding it. Its task is to provide the foundation: consistent, low-friction, repeatable motion that both configurations can rely on, scan cycle after scan cycle. 🔗 In semiconductor environments, that foundation also has to hold under controlled conditions. Both variants are available for cleanroom applications up to ISO Class 6, with vacuum-compatible configurations reaching down to 10⁻¹¹ mbar. One drive component. Two system configurations. The ball screw holds the same position in both — the mechanical basis everything else is built on. 🔔 Follow us for more engineering insights on how component decisions shape system behavior. #BallScrews #EngineeringInsights #SystemDesign #SemiconductorIndustry #MadeInGermany
