We machine custom spur, helical, and splined gear shafts using mill-turn machining, hobbing, and hard tooth grinding. Engineered to AGMA 10+ / ISO 6 standards with journal runout within 0.01 mm and bearing fit tolerances down to ±0.005 mm for low-backlash robotic drives.
Gear shafts drive torque transmission and positioning accuracy in robotic actuators. Pitch line runout, spline alignment, and bearing journal tolerances directly govern noise, backlash, and service life. Our mill-turn machining and tooth profile grinding keep shaft runout within 0.01 mm and journal fits down to ±0.005 mm, preventing assembly binding and minimizing vibration under high load.

Single-setup mill-turn machining maintains strict journal runout within 0.01 mm, eliminating cumulative errors between shaft journals and splines.
Secondary CNC profile grinding after carburizing heat treatment eliminates distortion, securing AGMA 10+ tooth accuracy for low-backlash drives.
Precision grinding holds bearing seats and journal tolerances to ±0.005 mm, ensuring smooth press-fits and preventing assembly binding under heavy load.
Every production batch undergoes 3D CMM inspection for gear profiles, pitch error, shaft straightness, and material test certificates (MTC).
