Manufacturing & Processing Capabilities

To control thermal distortion and hold strict dimensional tolerances, production integrates dedicated CNC machining cells:

Gear Hobbing & Shaping: High-speed CNC hobbers and shapers producing accurate involute profiles and uniform tooth thickness.

Gear Grinding: Form and generating grinders correcting heat-treatment distortion to achieve DIN 6 tooth accuracy and optimal surface contact ratio.

Heat Treatment: Controlled-atmosphere carburizing, quenching, and tempering furnaces ensuring consistent metallurgical microstructure and minimal residual stress.

Turning & Boring: Multi-axis CNC lathes maintaining precise bore concentricity and datum face perpendicularity.

Typical Applications

Industrial Gearboxes

Helical and bevel gear trains for industrial speed reducers and winches.

Automotive Powertrains

Differential assemblies, steering systems, and vehicle axle drives.

Robotics

Harmonic and planetary reduction gearboxes demanding zero-backlash precision.

Agricultural Machinery

PTO drive lines, tractor transmissions, and harvester gearboxes.

Quality Control & Metrology

Every batch undergoes strict inspection before packaging to guarantee interchangeability and operational reliability:

Gear Measurement Center (GMC): Automated verification of profile error (Fα), helix error (Fβ), pitch error (Fp), and radial runout (Fr).

Surface Profilometry: Flank roughness control maintained at Ra ≤ 0.4 μm to minimize friction and noise.

Hardness Testing: Rockwell and Vickers testing verifying surface case depth and core strength.

Rolling & Mesh Testing: Static check fixtures detecting abnormal meshing stiffness or runout anomalies.

Frequently Asked Questions

Q: What file formats are required for custom gear RFQs?

A: Please provide 2D production drawings (PDF/DXF) indicating module, pressure angle, tooth count, tolerance grades, and heat treatment specifications, alongside 3D models (STEP/IGES) for envelope validation.

Q: What is the typical lead time for custom samples versus mass production?

A: Prototypes require 2 to 4 weeks depending on material availability and tooling. Production batches average 6 to 10 weeks based on volume and finishing requirements.

Q: Can you manufacture gears from physical samples without engineering drawings?

A: Yes. Reverse engineering utilizes coordinate measuring machines (CMM) and optical gear testers to generate accurate production drawings for client approval prior to manufacturing.

Q: What backlash levels can be achieved on precision reduction gears?

A: Depending on the module and precision grade (DIN 6/7), backlash can be tightly controlled down to 0.02 - 0.05 mm.

Q: How do you prevent gear deformation during heat treatment?

A: Carburizing and quenching processes utilize specialized press-quenching dies and tight atmospheric controls to suppress thermal distortion prior to finish grinding.

Q: What corrosion protection and packaging are used for export?

A: Gears are coated with industrial rust-preventative oil, wrapped in VCI (Vapor Corrosion Inhibitor) paper, and packed in secure export-grade wooden crates or compartmentalized heavy-duty cartons.
