Gear Types We Manufacture
We manufacture a broad range of gear geometries and sizes. Each type below links to the same engineering team, so you are not forced to coordinate between multiple suppliers for different gear families.
Spur Gears (Straight-Cut)
The most common gear form for parallel-shaft power transmission. We produce spur gears in module 0.3–8, diameters from 5 mm to 500 mm, and materials including carbon steel, stainless steel, brass, and engineering plastics. Standard pressure angles include 20° and 14.5°.
- Applications: gearboxes, pumps, robotics, power tools, appliances
- Typical tolerances: ISO 1328 Grade 6–8 as-cut, Grade 4–5 after grinding
- MOQ: 100 pieces for machined, 5,000 for powder metallurgy
Helical Gears
Helical gears offer smoother engagement and higher load capacity than spur gears. We cut and grind helical gears with helix angles from 15° to 45°, module 0.5–6, and precision levels up to ISO 1328 Grade 5.
- Applications: automotive transmissions, industrial gearboxes, high-speed drives
- Materials: 4140, 8620, 20MnCr5, 316L, 17-4 PH
- Finishing: gear grinding, honing, shot peening available
Internal & Ring Gears
Internal gears and ring gears are machined by shaping, broaching, or wire EDM depending on size and quantity. Capabilities include internal diameters from 20 mm to 300 mm and module 0.5–6.
- Applications: planetary gearboxes, winches, slewing drives, robotics joints
- Specialty: segmented rings, thin-wall rings, custom tooth profiles

- Special features: hubs, keyways, set screws, secondary bores, surface coatings
Manufacturing Processes — How We Make Your Gears
Selecting the right gear manufacturing process depends on part geometry, annual volume, tolerance class, surface-finish requirement, and target unit cost. Emitech offers six primary processes, often combined in hybrid workflows.
CNC Gear Hobbing
Gear hobbing is the most efficient process for external spur and helical gears at medium-to-high volumes. A rotating hob cuts the tooth profile progressively, delivering excellent productivity and consistent quality. We use CNC hobbers with automatic loading for batch sizes from 500 to 100,000+ pieces.
- Best for: external spur and helical gears, module 0.5–8
- Typical quality: ISO 1328 Grade 6–8
- Advantages: lowest per-piece cost at volume, fast cycle times
CNC Gear Shaping
When gears have internal teeth, close shoulders, or features that prevent hob access, gear shaping is often the only practical solution. Our CNC shapers cut internal and external gears with high accuracy and good surface finish.
- Best for: internal gears, cluster gears, gears adjacent to shoulders
- Typical quality: ISO 1328 Grade 6–8
- Advantages: capable of internal and external profiles in one setup
Precision Gear Grinding
For applications requiring low noise, long life, or tight positional accuracy, we finish-cut or grind gears after heat treatment. Precision grinding removes heat-treat distortion and achieves ISO 1328 Grade 4–5, AGMA 12–14.
- Best for: aerospace, automotive transmission, high-speed industrial drives
- Typical quality: ISO 1328 Grade 4–5
- Advantages: highest accuracy, minimal noise, compensates for heat-treat distortion
Powder Metallurgy (PM) Gear Manufacturing
Powder metallurgy gears are pressed and sintered from metal powder, making them ideal for high-volume applications where material waste must be minimized. At volumes above 10,000 pieces, PM gears typically cost 30–50% less than machined equivalents.
- Best for: high-volume spur and simple helical gears, module 0.5–4
- Materials: iron-copper-carbon, pre-alloyed steel, diffusion-alloyed steel
- Advantages: near-net-shape, minimal machining, consistent density
Metal Injection Molding (MIM) for Micro Gears
For gears weighing less than 100 g or requiring complex three-dimensional geometry, metal injection molding offers an excellent balance of precision and cost. MIM can produce micro gears with fine teeth, undercuts, and integrated shafts in a single molding operation.
- Best for: micro gears, complex small gears, high-volume precision parts
- Materials: 316L, 17-4 PH, 4605, 8620, titanium
- Advantages: complex net-shape, minimal secondary machining, tight tolerances
Wire EDM & Rapid Prototyping
For prototypes, replacement gears, or geometries that cannot be economically tooled, wire EDM and CNC milling provide fast turnaround without custom cutting tools. We can deliver first articles in 5–10 business days.
- Best for: prototypes, low volumes, hard materials, specialty profiles
- Typical quality: ISO 1328 Grade 7–9
- Advantages: no tooling investment, fast lead time
Process selection directly affects gear cost. Powder metallurgy and MIM become cost-advantaged at higher volumes.

Gear Design for Manufacturability (DFM)
Small design decisions have a large impact on gear cost and quality. The guidelines below summarize what Emitech's gear engineers review during every DFM cycle. Addressing these points before tooling reduces rework, shortens lead time, and improves first-article success.
Module & Tooth Count
Choose standard modules wherever possible (0.5, 0.8, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0). Standard cutters reduce tooling cost and lead time. For very small gears, module 0.3–0.5 is achievable but requires careful material selection and inspection.
Face Width & Aspect Ratio
Face width should generally be 6–12 times the module for stable cutting and adequate load capacity. Excessively wide faces relative to diameter can cause deflection during hobbing and uneven load distribution in service.
Hubs, Bores & Keyways
Specify bore tolerance and keyway standard (e.g., DIN 6885, ANSI B17.1). For powdered-metal or MIM gears, consider net-shape bore features to eliminate secondary machining, but allow for post-sintering sizing if tight tolerances are required.
Undercuts & Fillets
Generous root fillets improve bending fatigue strength and reduce stress concentration. Avoid sharp internal corners at the tooth root; a minimum root fillet radius of 0.2 mm is recommended for cut gears.
Material & Heat Treatment Pairing
Match material and heat treatment to the operating environment. High-load steel gears usually require carburizing or induction hardening. Corrosion-resistant applications favor 300-series stainless or precipitation-hardened 17-4 PH. Plastic gears prioritize wear resistance and low noise.
Tooth profile, helix angle, and module selection directly affect manufacturability and performance.
Secondary Operations for Gears
After primary cutting or molding, gears often require secondary operations to meet final specifications. Emitech manages these operations in-house or through qualified partners, with full inspection and documentation.
Shaft & Bore Finishing
Reaming, honing, grinding, and wire-EDM finishing for tight bore tolerances and precise shaft fits.
Surface Hardening
Carburizing, nitriding, induction hardening, and carbonitriding to improve wear resistance and fatigue life.
Coatings & Platings
Black oxide, zinc plating, nickel plating, electroless nickel, PVD, DLC, and passivation for corrosion or wear protection.
Grinding & Honing
Profile grinding, generating grinding, and honing for noise reduction and precision improvement.
Marking & Traceability
Laser marking, dot-peen marking, and serialization for part traceability in medical, aerospace, and automotive applications.
Common Gear Failure Modes & Prevention
Understanding how gears fail helps engineers specify the right material, heat treatment, and quality level from the start. Below are the most common failure modes Emitech reviews during design for manufacturability.
| Failure Mode | Typical Cause | Prevention Strategy |
|---|---|---|
| Tooth bending fatigue | Insufficient root fillet, overload, poor material choice | Increase fillet radius, upgrade material, add case hardening |
| Pitting / contact fatigue | High contact stress, inadequate surface hardness | Increase surface hardness, improve finish, use profile grinding |
| Wear / abrasion | Contamination, soft tooth surfaces, poor lubrication | Harden teeth, improve sealing, specify coating or plating |
| Scuffing / scoring | High sliding speed, inadequate lubrication, excessive load | Optimize lubrication, reduce load, use anti-scuff coatings |
| Plastic deformation | Overload, low yield strength, high temperature | Select higher-strength material, reduce operating temperature |
| Thermal distortion | Uneven heat treatment, thin sections, poor fixturing | Control heat-treat process, add grinding after hardening |
Case Study: Automotive Transmission Spur Gear
Challenge: A Tier-1 automotive supplier needed 50,000 pieces per year of a module-1.5 spur gear in 8620 steel, with case hardness 58–62 HRC, core hardness 30–45 HRC, and ISO 1328 Grade 6 accuracy.
Solution: Emitech selected CNC gear hobbing for the tooth form, followed by carburizing and quenching, then CNC profile grinding for final tooth accuracy. Bore finishing and laser marking were added as secondary operations.
Result: First-article approval was achieved on the second submission. The customer reduced per-piece cost by 18% compared to their previous supplier while improving on-time delivery to 98%.
Case Study: Medical Device Micro Gear
Challenge: A medical OEM required a 6 mm diameter stainless steel gear with 20 teeth, integrated hub, and tight concentricity for a surgical instrument.
Solution: Metal injection molding in 316L stainless steel was selected to produce the complex net shape, followed by minimal bore reaming and passivation.
Result: The MIM process eliminated multi-axis machining and reduced unit cost by 40% at 10,000 pieces per year. Passivation ensured biocompatibility and corrosion resistance for repeated sterilization cycles.
Micro gears in stainless steel and titanium are ideal for MIM when complex geometry and high volume are required.
