HONPINE Establishes Ultra-Fine Grain Harmonic Reducer R&D and Production Center, Aiming to Surpass Japan's Harmonic Drive in Precision
To meet the growing demand for higher precision in harmonic reducers from customers in CNC, humanoid robots, medical equipment, and other application fields, HONPINE has established an ultra-fine grain R&D and production center. The center plans to adopt ultra-fine grain production technology to enhance the precision and rigidity of harmonic reducers.
Why Adopt Ultra-Fine Grain Production Technology?
1,Through ultra-fine grain heat treatment, an average grain size of ≤7μm can be achieved, reaching an ultra-fine grain level of 11–11.5 grade with superior organizational uniformity.
2,Material properties include a tensile strength of 1,500 MPa, yield strength of 1,425 MPa, yield ratio of 0.95, and strength-ductility balance >15,000.
The table below shows the tensile test results after heat treatment:
Ultra-Fine Grain Manufacturing Process
Ultra-fine grain heat treatment process: Raw material → Hot forming → Pre-treatment → Heat treatment → Surface treatment
What Performance Can Be Achieved with Ultra-Fine Grain Technology?
Gear accuracy grade < DIN4, roundness < 0.003, dimensional error < 0.01
HONPINE’s R&D Focus
HONPINE’s R&D direction is driven by customer and market demands. In 2025, the primary focus is addressing the need for improved precision and rigidity in harmonic reducers. In addition to the ultra-fine grain R&D project, the new ultra-fine planetary reducer represents a major technological breakthrough (completely resolving the trade-off between precision and rigidity in harmonic reducers).

HONPINE Develops the World’s First HPG-10T-74-AG1-30-A-C-K11 Self Anti-Backlash High-Precision Planetary Rotary ActuatorOn July 8, 2025, HONPINE successfully developed the world’s first HPG-10T-74-AG1-30-A-C-K11 Self Anti-Backlash High-Precision Planetary rotary actuator. This cutting-edge reducer, designed for a leading laser cutting machinery manufacturer, features ultra-high precision and ultra-high torsional rigidity. It resolves a long-standing industry challenge: the inability to simultaneously achieve high precision and high rigidity in a single reducer unit.- HONPINE Harmonic Reducer, RV Reducer, Planetary Reducer Assist in the Development of Humanoid RobotsHumanoid robots are evolving from demonstrating capabilities in laboratories to wide-ranging industrial applications. A productivity revolution driven by lightweight materials, embodied intelligence and autonomous battery replacement technology is taking place in factories, hospitals and homes worldwide. The "joint revolution" of humanoid robots is underway. A humanoid robot consists of thousands of components, among which actuators, as the most critical moving parts, are called the robot's "joints and muscles." Harmonic reducers are widely used in rotary joints due to their high precision and compact size.
- HONPINE Humanoid Robot Joint Module New Factory Set to OpenThe new HONPINE Humanoid Robot Joint Module Factory has undergone renovations for over five months and is scheduled to commence operations on August 28, 2025. To address growing market demand and ensure both product quality and production capacity of joint modules, HONPINE has invested $15 million in constructing this facility.
