Services

What we make

Send a drawing, the worn part, or a few photos with measurements. We'll work out the gear data and get it built fast.

Replacement Gears

OEM part discontinued, or the original maker out of business? We measure your worn gear, work out the tooth geometry and make a new one that fits.

Start with
A drawing, the old part, or photos with measurements
Includes
Reverse engineering and tooth data
Quantity
Single pieces welcome
Quote a replacement

Prototype Gears

One-offs and short runs for new equipment and R&D, with design review before anything gets cut and pricing that makes sense for small quantities.

Start with
CAD model and drawing (STEP, DXF, PDF)
Includes
Design review and manufacturability feedback
Quantity
1 to 10 pieces
Quote a prototype

Production & Repeat Orders

Once a gear's tooling and programs are on file, every reorder is even faster, with the same inspection on every piece.

Reorders
Faster every time, tooling on file
Options
Single shipment or blanket orders
Quality
Inspection report with every order
Quote a production run

Turnaround

The best lead times in the industry

Replacement gears from the OEM can sit on back-order for months. We build custom gears to order, fast, without cutting corners on quality.

Waiting on the OEM

  • Long lead times and back-orders
  • Discontinued parts with no replacement
  • Minimum order quantities
  • Equipment sits idle while you wait

Hotshot Gears

  • Built to order with fast turnaround
  • Reverse engineered from your old gear
  • Single pieces welcome
  • A firm ship date with every quote

How we keep it fast

Every quote includes a firm ship date. Lead time depends on size, material, heat treatment and quantity.

How it's made

CNC at every step, from blank to inspection

CNC means the machines are computer-controlled. A precision gear passes through several of them, each doing a different job.

  1. Turning & blankingA CNC lathe shapes the blank: outside diameter, bore and faces, before any teeth exist.
  2. Gear hobbingThe main way teeth are cut. A worm-shaped hob turns in sync with the blank. Fast and accurate for spur and helical gears.
  3. Gear shapingA reciprocating cutter for teeth a hob can't reach, such as internal gears and gears next to a shoulder.
  4. Heat treatmentCarburizing or through-hardening for strength and wear life, with hardness verified after.
  5. Gear grindingHardening distorts the part slightly, so the teeth are ground back to precise shape. This is how high accuracy grades are reached.
  6. Thread & ID/OD grindingWorms, threads, bores and diameters ground to tight tolerances so the gear runs true on its shaft.
  7. Gear inspectionA CNC gear analyzer measures profile, lead, pitch and runout and reports the accuracy grade achieved.
Quality & documentation

Inspected in-house. Shipped with the paperwork.

Every gear is traceable from the steel it was cut from to the inspection that passed it. You get the records with your order, and we keep them on file.

  • Material tracked by heat number through every operation
  • First part off each setup fully measured before the run continues
  • Hardness checked after heat treat
  • Gauges calibrated to national standards

What ships with your gears

  • Certificate of ConformanceSigned by quality, confirming the parts meet your drawing and PO.
  • Material certsMill test reports traceable to the heat number.
  • Heat treat certHardness and case depth results.
  • Inspection reportDimensional results and gear analyzer charts showing the achieved grade (AGMA 2015 / ISO 1328).
  • First article reportOn request.
