Custom CNC Machined Precision Metal Gear: Technical Guide
Custom CNC Machined Precision Metal Gear: Technical Guide
Understanding tolerance, materials, and design options for custom precision spur gears used in power transmission systems.
Overview
A custom CNC machined spur gear delivers tight tolerances and repeatability for power transmission in automotive, robotics, and industrial equipment. Machined from stainless steel, it combines fine-pitch teeth, a precision center bore, and lightening holes for a strong, lightweight design.
Key Manufacturing Features
- Tooth profile: Hobbed or wire-EDM cut for low backlash
- Center bore: Ground to ±0.01mm tolerance
- Lightening holes: Reduce mass, retain torque capacity
- Finish: Brushed stainless steel resists corrosion
Why CNC Machining?
CNC-machined gears outperform cast or stamped parts in dimensional accuracy, surface hardness, and load capacity — critical for high-RPM or high-torque assemblies.
Frequently Asked Questions
QWhat tolerance can CNC gears achieve?
Typically ±0.005–0.01mm on bore and critical diameters.
QWhat materials are common for custom gears?
Stainless steel, carbon steel, and aluminum, selected by load and corrosion requirements.
QWhat is the standard sample lead time?
Usually 7–10 days for prototype gears.
QCan gear design be fully customized?
Yes — tooth count, module, bore size, and hole layout are all customizable per drawing.
