BG650 Long Travel Stage

BG650 Long Travel Stage

Split Gantry using BG650 Stages The BG650 is a long travel stage used for inspecting or processing larger parts such as flat panels and circuit boards. Many options are available, including lead screw or ball screw drives, stepper motors, servo motors, or “smart” motors with integral controllers (shown above), connector bulkheads, and side seals. Even though the BG650 is an economical stage, performance has not been compromised. A stiff stage body machined from 7075 aluminum ensures angular errors (pitch, yaw, roll) and straightness errors (straightness and flatness of travel) are kept to a minimum. Large, precision linear rail guides with recirculating, caged ball bearings provide smooth, quite travel, long life and high load capacity. Because many of our stages are integrated into metrology instruments or process tools, we pay a lot of attention to the quality of all external surface finishes.
