Why linear motor? A linear motor is a direct-drive motor that produces straight-line motion directly — no belts, gears or ball screws in the power path. That removes mechanical backlash and lets the axis start, stop and reverse almost instantly, which is exactly what long-stroke, high-dynamics gantry work needs.

What happens when you strip the belts and ball screws out of a gantry mill? You get instantaneous responsiveness, zero mechanical backlash, and cycle times that actually hold up under pressure.
The Gree GA-GF3755 leverages a linear-motor direct drive to hit a 70 m/min rapid traverse and 7.5 m/s² acceleration — paired with a 20,000 rpm spindle and thermal compensation to keep tolerances tight across all 3.7 m of X-travel. With a 20-tool ATC and our 5-year warranty, it's built to run long-bed components non-stop.
Are you still using traditional ball-screw gantries for long-stroke parts, or have you made the switch to direct drive?
