Why Choose Our Gear Shaping Services?
When your project involves internal gears with blind holes, cluster gears with tight clearances, or complex splines, gear shaping is the essential solution.
At Hansheng Automation, we supply high-precision CNC gear shaping that achieves ISO/DIN Grade 6–9 accuracy. Leveraging the advanced YS5120CNC four-axis high-speed system and Nidec Gear Shaping Machine SE25FR, we can do:
The "Blind Hole" Specialist
Perfect for internal gears where a through-hole is impossible, providing clean tooth profiles right up to the relief groove.
Cluster Gear
Seamlessly machining multiple gear steps on a single shaft where space between gears is too tight for hobbing.
High-Speed Stability
Our 4-axis 3-linkage CNC technology ensures consistent tooth thickness and lead accuracy.

advanced Gear Shaping Equipment: Nidec & YS5120CNC
Nidec SE25FR
High Speed & High Efficiency Machining Capability
The SE25FR achieves a spindle stroke speed of up to 1,800 strokes/min. Machining a gear with a module of 0.4mm and 162 teeth takes only about 2.08 minutes for the complete process.
High Machining Accuracy
The SE25FR delivers machining accuracy up to ISO class 6, making it our primary equipment for machining harmonic drive gears.
YS5120CNC
Exceptional Production Speed
With a speed of up to 1,750 strokes/min, it significantly shortens the machining cycle and provides customers with a faster delivery lead time.
Unmatched Rigidity & Finish
The machine tool utilizes a high-rigidity design and structural components to minimize vibration and noise generated during operation, ensuring surface finish and dimensional tolerance of the workpiece.
Flexible Feed Control
A wide range of circumferential and radial feed options allows us to optimize the cutting process for different materials-from tough alloys to delicate micro-gears.
High Automation & Consistency
The equipment is highly automated with precise parameter control. It strictly complies with ISO grade 7–9 standards.
Applications & Solutions
CNC gear shaping is the most versatile solution for high-precision components that traditional hobbing or broaching cannot reach. At Hansheng, our gear shaping process has provided machining services for the following fields.
Internal Gears & Splines (Blind Holes & Shoulders)
Our shaping process excels at machining internal gears with blind holes or teeth that end abruptly at a shoulder.
High-Density Cluster Gears
Our gear shaping cutters move vertically, allowing us to machine teeth in tight-clearance areas that are inaccessible to other tools.
Micro-Module Precision Instruments
We handle modules as small as 0.1m. Our high-speed CNC stability ensures that these tiny teeth maintain their profile integrity.
Core Industries We Serve
Our ISO 7–9 gear shaping capabilities are trusted by industry leaders in sectors where precision and reliability are non-negotiable:
- Precision reducers: such as internal gears of RV reducers for robot joints and harmonic drives.
- High-End Pumps & Valves: Providing durable internal splines for fluid power transmission systems.
- Automotive Precision Transmissions: Producing cluster gears and specialized synchronizers for high-performance vehicles.
Quality Assurance & Inspection
Every gear shaped in our facility undergoes a rigorous metrology process to ensure it meets your exact specifications.We use advanced tooth profile testers and other gear measurement centers (GMCs)
We will inspect various key parameters of the gears, including Total Profile Deviation (Fα) and Profile Shape Deviation (fα), Lead / Helix Deviation (Fβ), Pitch Error (Fp) and Individual Pitch Deviation (fp), as well as Runout (Fr). Upon shipment, we will provide the corresponding inspection report according to your requirements.
Service Synergy
Choosing the right manufacturing process is critical to balancing cost and performance. Our factory is equipped with a full spectrum of gear-cutting technologies, allowing us to be your one-stop partner for any transmission challenge.

FAQ
Q: What is the maximum accuracy level you can achieve for internal gears?
A: Through our gear shaping process, the internal gears produced achieve an accuracy within the ISO/DIN 7–9 range. If you require higher precision, you may choose our gear skiving and gear grinding processes.
Q: Can you machine gears with a shoulder or blind hole?
A: Yes. Gear shaping is the preferred manufacturing method for gears with restricted clearance. Unlike gear hobbing, our YS5120CNC shaper uses a vertical reciprocating motion, allowing the cutter to machine teeth right up to an internal shoulder or the bottom of a blind hole (provided a small relief groove is present for chip clearance).
Q: What is the lead time for custom gear shaping?
A: Lead times typically range from 2 to 4 weeks for prototypes and 4 to 8 weeks for mass production runs. Factors affecting the timeline include material availability, heat treatment requirements, and whether a standard or custom-module cutter is needed.
