Custom Precision Spur Gears – CNC Machined to Your Exact Specifications

Product Description

Yile Machinery is your trusted partner for the custom manufacturing of high-precision steel spur gears. We leverage state-of-the-art CNC gear cutting technology to transform your technical drawings into finished components that meet the most demanding tolerances. Whether you require a single prototype for a new design or full production runs for your OEM machinery, we deliver quality you can count on.

Our Manufacturing Process: Precision at Every Step

We provide a complete, in-house manufacturing service to ensure total control over quality and lead times.

  1. Material Sourcing: We start with certified carbon and alloy steels such as C45 (AISI 1045) , 40Cr, and 42CrMo (AISI 4140) to meet your strength and durability requirements.

  2. CNC Turning: The gear blank is first precision-turned on our CNC lathes to establish exact outside diameters, bore sizes, and hub features.

  3. Precision Gear Cutting: This is the critical step. Using advanced CNC Gear Hobbing machines, we cut the gear teeth with exceptional accuracy and surface finish. For internal gears or special features, we also utilize CNC Gear Shaping.

  4. Finishing & Deburring: All gears are meticulously deburred to ensure smooth operation and safe handling.

  5. Optional Heat Treatment: We offer induction hardening or case hardening (carburizing) to increase the surface hardness of the gear teeth, dramatically improving wear resistance and service life while maintaining a ductile core.

Your Gear, Your Specifications

We are a true custom manufacturer. We build gears based on the parameters you provide:

  • Material: Carbon Steel, Alloy Steel, Stainless Steel, etc.

  • Gear Standard: Module (Metric) or Diametral Pitch (Imperial)

  • Dimensions: Tooth Count, Pressure Angle, Face Width

  • Bore & Hub: Custom Bore Diameter, Keyways, Set Screw Holes, Splines

  • Heat Treatment: Specific Surface Hardness (HRC) and Case Depth

  • Quality Grade: Manufactured to meet specific AGMA or DIN quality standards.

Commitment to Quality and Inspection

Precision is not just a goal; it's a guarantee. Our quality assurance lab is equipped with the necessary tools to inspect and verify every critical dimension of your gear, ensuring it conforms perfectly to your print. We can provide inspection reports upon request.
