Optimized for Accuracy, Velocity, and Utility-Particular Wants.
PI USA Supplies Engineered Precision Gantry Positioning Programs. Picture Credit score: PI (Physik Instrumente) LP
PI (Physik Instrumente), a world chief in movement management and high-precision automation applied sciences, affords customized precision gantry movement techniques, engineered for high-accuracy industrial purposes like inspection, metrology, laser processing, micro-assembly, and high-end 3D printing. Designed and fabricated by PI’s US operation in Hopkinton, MA, this method displays PI’s dedication to extremely dependable, domestically manufactured, precision automation options.
Balanced Design for Rigidity and Responsiveness, Primarily based on Commonplace Fashions and Modules
With three commonplace gantry product traces (A-341, A-351, A-352), together with air-bearing and mechanical-bearing designs, PI’s engineering staff can rapidly modify and optimize gantries for particular buyer purposes. All designs leverage FEA-backed improvement to make sure structural rigidity with out pointless mass — addressing one of many seven core engineering challenges in gantry techniques: sustaining stiffness throughout lengthy spans.
Absolute Sensors and Friction Free Motors Present Accuracy and Movement High quality
Geared up with absolute linear encoders delivering 1nm decision, PI’s precision gantry techniques get rid of time-consuming homing cycles and guarantee excellent positional accuracy. The ironless, friction-free, cog-free motor structure delivers easy, vibration-free movement with quick acceleration and distinctive velocity management.
Movement Controllers with Constructed-in Gantry Intelligence
Trendy precision gantry techniques should deal with complicated coordination points — particularly racking brought on by drive mismatches in dual-driven bridges. PI options mitigate such errors by way of ACS movement controllers that help gantry-alignment routines to compensate for angular misalignments utilizing digital rotation axes. Particular gantry yaw management algorithms additionally enable for lively rotation (Theta-Z) whereas locking the linear axes when the gantry is provided with flexure joints.
Dynamic Capabilities for Actual-World Efficiency
Typical Journey Ranges: 300 mm to 2 m
Variety of Axes: From 2 axis to 10+ axes. Integration of hexapods, piezo nanopositioning phases, and so forth.
Prime Velocity: As much as 2 m/s on the cross-axis
Superior Options: Dynamic error mapping, elective water-cooling, drag chain cable carriers for high-duty purposes
Z Axis Choices: Select between ball-screw or linear-motor-based vertical movement, with magnetic or pneumatic counterbalance for load balancing and easy vertical dynamics
Trade-Main Management Platform
Timing precision is vital when coordinating movement with course of steps like imaging or laser activation. The {hardware} timed outputs, synchronized straight with encoder suggestions, guarantee flawless occasion positioning — eliminating picture blur or half misplacement. Moreover, considerate cable administration, together with specialised drag-chain routing for clear environments, assures dependable repeatability.
