Custom gears to drawing or sample
Custom Gear Machining to Drawing or Sample
Send a drawing or the worn gear. We cut, heat treat, finish and inspect it to the class you need. Prototypes, replacements and production batches. Reply within 24 business hours.
What does your gear quote need?
A complete gear request gets a firm price on the first reply. Tick what you already have.
Gears we make
- Spur gears
- Helical gears
- Bevel and miter gears
- Worm and worm wheels
- Racks and pinions
- Internal gears
- Sprockets
- Splined shafts
Gear blanks are turned first, then the teeth are hobbed, shaped or milled, heat treated and, for high classes, ground.
Hobbed or ground teeth?
Both make accurate gears. The difference is the quality class, the noise level and the price.
Hobbed or shaped
Teeth are cut by a hob or shaper cutter. The standard route for most industrial gears.
- Fast and cost effective
- Good for soft or through hardened gears
- Typical classes AGMA 8 to 10, ISO 8 to 9
Ground after hardening
Teeth are cut, case hardened, then ground to correct distortion.
- Quiet running at high speed
- Typical classes AGMA 11 to 13, ISO 5 to 6
- Higher price, needed for precise drives
Typical gear materials and treatments
What to expect in each material. These are typical values, not promises. Your quote confirms them for your gear.
| Material | Typical treatment | Typical use |
|---|---|---|
| 4140 / 42CrMo4 | Through hardened 28 to 34 HRC or induction hardened | Industrial drives, pinions |
| 8620 / 20MnCr5 | Case carburized 58 to 62 HRC | High load, gearboxes |
| 1045 / C45 | Normalized or induction hardened | Low to medium load, sprockets |
| Bronze (phosphor, aluminum) | None | Worm wheels, wear partners |
| Stainless 303 / 17-4 | None or precipitation hardened | Food, marine, corrosive service |
| POM, nylon | None | Quiet, light load, no lubrication |

Tell us the speed, load and lubrication. We match material and class to the job.
Industrial gearboxes
Spur and helical sets, pinions and shafts.
Conveyors and material handling
Sprockets, racks, worm drives.
Agriculture
Replacement gears for older equipment.
Printing and packaging
Precise helical gears for quiet, accurate drives.
Robotics and automation
Small module gears and racks.
Pumps and mixers
Bevel and worm sets for heavy duty.
How it works
You send the problem. We take it from drawing to delivery and keep you informed at each step.
Send your files
Drawing or gear data sheet. No drawing? Send the worn gear or the mating gear.
We review and quote
We check the gear data, material and class, then quote the price and lead time.
We produce and inspect
Blank turning, tooth cutting, heat treatment and finishing, then gear inspection.
We deliver
Gears with inspection report and hardness results, packed against rust and damage.
What drives the price of a custom gear
Five things decide most gear quotes.
- Quality classEach step up in class adds machine time, grinding and inspection.
- Heat treatmentCase hardening adds a process, distortion and often grinding.
- Size and moduleLarge gears need bigger machines. Very fine modules need special tooling.
- ToolingNon-standard modules or profiles may need a dedicated hob or cutter.
- QuantitySetup is paid once. Batches lower the price per gear quickly.

Cut gears or heat treat them?
We work with production shops, component suppliers and engineers in this field. Register once and we send you project scopes that fit what you do. We handle the customer side.
Questions customers ask
Something else? Email .
Can you make a gear from a worn sample?
Yes. We measure tooth count, module, pressure angle and helix angle, check the mating gear if available and draw the gear before cutting. You approve the gear data first.
What is the smallest order?
One gear. Single replacement gears are common. Batches lower the price per piece because setup and tooling are paid once.
Which quality class can you reach?
Hobbed gears typically reach AGMA 8 to 10. Ground gears typically reach AGMA 11 to 13. The quote states the class for your gear and how it is checked.
Do you supply the shaft as well?
Yes. Pinion shafts, splined shafts and gear and shaft assemblies are made to drawing like any gear.
Do you make the gears yourselves?
Production runs at partner shops we have audited for this kind of work. We stay responsible for the order: we review the drawing, pick the shop, follow production, inspect before shipping and deliver to you. You deal with one contact and one purchase order.
Can you sign an NDA first?
Yes. Tick the NDA box on the quote form and we sign one with you before anyone outside our team opens your files. Every partner on the project works under the same terms.
