CNC (computer numerical control) gear part processing involves a variety of processes. The following are some common CNC gear processing processes:
Gear cutting:
Gear hobbing: Use a hobbing tool to continuously cut on the gear
blank to form a tooth shape.
Gear shaping: Use a shaping tool to shape the tooth shape on the
gear blank, which is suitable for the processing of precision
gears.
Gear shaving: Finishing the gear that has been hobbed or shaped to
improve the accuracy and surface quality of the gear.
Gear grinding:
Tooth surface grinding: Use a grinding tool to grind the tooth
surface of the gear to achieve higher accuracy and surface finish.
Tooth profile grinding: Accurately grind the tooth shape of the
gear, which is suitable for the processing of precision gears.
Gear heat treatment:
Carburizing and quenching: Improve the hardness and wear resistance
of the gear, usually after gear cutting.
Nitriding: Form a nitride layer on the surface of the gear to
improve its hardness and wear resistance.
Gear finishing:
Gear honing: Use a honing tool to finish the gear to improve the
accuracy and surface quality of the gear.
Gear grinding: Gears are processed with grinding tools for
ultra-precision.
Gear hole processing:
Drilling: Gears are drilled using CNC drilling machines.
Reaming: Gear holes are finished using reamers.
Boring: Gear holes are processed using boring tools, which are
suitable for gears with large apertures or high precision
requirements.
Gear measurement and inspection:
Gear measurement: Gear measuring instruments are used to measure
the size, shape and position accuracy of gears.
Gear inspection: Check the processing quality of gears, including
tooth shape, tooth pitch, tooth surface roughness, etc.
Gear deburring and cleaning:
Deburring: Deburring tools or equipment are used to remove burrs
generated during gear processing.
Cleaning: Clean the gears to remove oil, cutting fluid and burrs to
ensure the cleanliness of the gears.
These processes can be used alone or in combination to achieve
different processing requirements and precision levels of gear
parts. The application of CNC technology makes these processes more
automated, precise and efficient.
