YK3150: Where Gear Manufacturing Meets Zero-Transmission Precision

Overview
The YK3150 CNC gear hobbing machine isn’t just cutting gears—it’s eliminating bottlenecks in transmission manufacturing. By integrating dual direct-drive motors (B/C-axis) and torque-multiplying electronic gearbox (EGB) technology, it achieves GB/T10095 7-grade accuracy on helical gears up to 8-module while slashing energy use by half. From wind turbine ring gears to e-bike drivetrains, users report 45% faster cycle times and 90% setup error reduction.

1. Surgical Precision: The Science Behind Zero-Transmission Architecture

Why Mechanical Backlash Became Obsolete

Core Innovations

Dual-Drive Revolution
- B-axis (hob spindle): 2000rpm synchronous servo motor eliminates 97% vibration vs belt-driven systems
- C-axis (worktable): Torque motor delivers 48N·m at 95rpm for distortion-free heavy cuts
Thermal Warfare
Oil-cooled NSK P4 bearings + forced circulation system maintain ±0.003mm positional stability during 10hr continuous runs

Accuracy Benchmark

Parameter	YK3150	Traditional Hobbing	Advantage
Profile Error	≤0.015mm	≤0.03mm	2x tighter
Adjacent Pitch	±0.005mm	±0.012mm	58% reduction
Surface Roughness	Ra1.6μm	Ra3.2μm	Mirror finish

2. Efficiency Unleashed: One Machine, Five Processes

Beyond Gears: The Multi-Tasking Breakthrough

No-Changeover Production

Helical Gears (β≤45°): EGB programming replaces differential gears – input Drawing parameters , get perfect spirals
Hardened Surfaces (HRC62): 350m/min carbide hob speed replaces grinding for camshaft sprockets
Non-Circular Gears: 4-axis coupling cuts eccentric planetary gears in one clamping

Real User Impact

*"Switching from mechanical hobbing to YK3150 reduced our gearbox production time from 22 to 12 minutes. The direct-drive C-axis eliminated shimming."*
