Overview

Cartesian robots, also called linear or gantry robots, use three orthogonal linear axes (X, Y, Z) to position an end effector with high repeatability. They excel at pick-and-place, dispensing, cutting, and assembly tasks across manufacturing lines where long reach and consistent payload handling are required. Their modular frames and simple kinematics make them easy to integrate, scale, and maintain for high-throughput or large-format applications.

FAQ

What should I inspect when buying a used Cartesian robot?

Check linear rail and ball-screw wear, frame straightness, motor and encoder operation, controller condition and compatibility, cable harnesses, end-effector interfaces, load capacity, and available service or calibration records.

How should shipping and on-site installation be handled?

Crate and secure long axes and rails, protect guides and motors, and consider partial disassembly for oversize gantries. Use a carrier experienced with industrial machinery and schedule a site survey so integrators can prepare foundations, power, and safety fencing.

What routine maintenance keeps a Cartesian robot reliable?

Perform daily visual checks, lubricate rails and bearings per maker guidelines, monitor motor temperatures and encoder signals, inspect belts and couplings, back up controller programs, and schedule annual calibration and preventive inspections.
