CNC horizontal gear hobbing machines in this size range are designed for workpieces up to Ø30 mm. They can machine a variety of small components used in precision devices, including spur gears, helical gears, worm gears, sprockets, timing-belt pulleys and splined parts.
This series of CNC horizontal gear hobbing machines handles workpieces up to Ø80 mm and is suitable for machining spur gears, helical gears, worm gears, sprockets, timing-belt pulleys and splined parts.
All models in this series work with a seven-axis structure and four-axis interpolation in a horizontal layout, giving the system enough control and rigidity for precision gear cutting.
These vertical CNC gear hobbing machines cover multiple size options and are built for high accuracy, efficient cutting and stable operation.
The YK7226 CNC grinding machines are designed for precise gear grinding in sectors such as instrumentation, automotive components and high-precision planetary reducers. It handles module 0.5–4 mm and workpieces up to Ø260 mm, covering the typical range required for small and medium worm gears.

Stability increases when the machine frame has sufficient rigidity, the spindle is dynamically balanced, and high-precision linear guides are used. Using coated carbide tools, setting reasonable cutting parameters, and keeping consistent cooling and lubrication all help reduce wear. When vibration monitoring is available, it supports smoother cutting and helps protect tool life at higher speeds.
CNC hobbing machines work with gears in the 0.5 to 4 mm module range and are suitable for diameters from 150 to 260 mm. That basically covers the sizes most workshops deal with when producing small to mid-size gears.
Machines equipped with the FANUC 31i-B control system allow quick model switching through program adjustments. Continuous generating processes enable efficient high-volume gear machining while maintaining consistent accuracy.
Cutting tools with good hardness and toughness offer better stability during gear machining. Edges that have been reinforced hold up more consistently under load. The tool diameter also needs to match the cutting depth, since tools with an excessive length-to-diameter ratio tend to vibrate and affect accuracy.
A high-rigidity machine bed and preloaded ball screws help suppress vibration during titanium alloy machining. Certain models include vibration-monitoring functions that adjust machining parameters in real time to maintain precision.
The worm-wheel gear grinders are designed to reach the precision required for EV reducer gears. They use continuous generating grinding, operate with the FANUC 31i-B control system, and work on a seven-axis platform with five-axis interpolation. Gear accuracy reaches GB Class 3, while still maintaining good machining efficiency.
