Customized Zero Backlash High Torque Robotics Components One Piece Formed Robot Harmonic Drive Sets

We provide full custom manufacturing of harmonic reducer core components based on your drawings, 3D models or sample parts. The product line covers three critical parts: Wave Generator, Flexspline and Rigid Wheel, all precision machined on Mazak INTEGREX i-200S turn-mill composite machining centers.

All turning, milling, drilling and gear cutting operations are completed in a single clamping setup to eliminate secondary positioning errors and deliver micron-level dimensional accuracy.

Crafted from high-strength alloy steels including 40Cr, 42CrMo and bearing steel, these custom core parts deliver excellent torsional rigidity, fatigue resistance and ultra-smooth meshing performance. They are purpose-built for industrial robot joints, collaborative robots and precision automation systems that demand zero backlash, high torque density and long service life.

Custom manufactured to your drawing specifications, the wave generator features a precision rotary elliptical outer profile integrated with a keyed bore, angled lubrication holes and end mounting flange — all completed in a single Mazak turn-mill setup.

The one-piece construction guarantees precise ellipticity and phase alignment, which accurately controls the deformation waveform of the flexspline and ensures smooth, uniform tooth meshing with zero radial runout.

The rigid wheel features high-precision internal gear teeth machined into a rigid outer flange body with custom-configured end mounting holes. We offer both gear skiving and hobbing processes to match your accuracy and volume requirements.

The integrally machined outer flange provides easy and stable installation, with accurate hole positioning for reliable bolted connection to the housing.

The flexspline adopts a custom thin-wall cylindrical design with precision internal gear teeth, delivering excellent flexibility while maintaining high structural strength and fatigue resistance.

Wall thickness, tooth profile and flange mounting interface can all be tailored to your specific torque and space requirements. The lightweight thin-wall structure reduces overall reducer weight and inertia, while the precision-machined tooth profile ensures perfect meshing for smooth, zero-backlash power transmission.
