Gear Manufaucturing Process Introduction

Key gear machining processes includes:
• Hobbing – most efficient for external spur/helical gears, high productivity
• Shaping – ideal for internal gears and shoulder-limited parts
• Gear grinding – highest precision (DIN 3-5), best surface finish & noise performance
• Shaving – cost-effective finishing before heat treatment
• Broaching – fast for internal splines and special profiles
• Hard skiving – rising star for hardened gears, replaces grinding in many cases
• Additive manufacturing & 5-axis milling – growing for prototypes and low-volume complex gears

Material → Turning → Hobbing/Shaping → Heat treatment → Grinding/Hard skiving/Shaving → Inspection is the classic flow. The process selection depends on volume, accuracy, cost and hardness requirements.
