See the equipment used to machine, heat-treat, finish and inspect custom gears and shafts, together with the checks and report formats that can be planned for a project.
PairGears' documented equipment covers turning, spur and helical gear cutting, bevel gear milling, gear grinding, heat treatment, cleaning, dimensional measurement, material verification and gear-geometry inspection. The final process route and inspection plan are confirmed from the drawing, material, accuracy grade, application and agreed documentation requirements.
An equipment name matters only when it is connected to the operation it performs, the feature it controls and the evidence a buyer may request.
Production equipment is grouped by its role instead of appearing as an unstructured photo gallery.
Inspection equipment is tied to specific characteristics so buyers can judge whether it fits their drawing.
Public report samples show the format and type of evidence available for selected projects.
The inspection route should follow the characteristics that affect fit, tooth contact, load distribution and material condition.
Profiles, edges, positions and selected two-dimensional features.
Vision measuring machine → dimensional resultsThree-dimensional features and drawing-defined geometric relationships.
CMM → dimensional / first-article reportChemical composition checked against the agreed metallic material requirement.
Spectrometer → composition recordProfile, helix or lead, pitch and runout according to the inspection plan.
Gear measuring center → gear inspection reportReview the equipment in manufacturing-process order. Machine allocation and acceptance criteria are confirmed after technical review.
These ranges help with early screening. They do not replace a drawing review or a project-specific process and inspection plan.
| Gear / process | Condition | Reference quality | Pitch | Module |
|---|---|---|---|---|
| Spur & helical - Hobbing | Before heat treatment | AGMA 10 / DIN 8 / JIS 4 | 0.55-128 DP | M0.2-M45 |
| Spur & helical - Shaping | Before heat treatment | AGMA 10 / DIN 8 / JIS 4 | 1-48 DP | M0.5-M25 |
| Spur & helical - Shaving | Before heat treatment | AGMA 11 / DIN 7 / JIS 3 | 4-32 DP | M0.8-M6 |
| Spur & helical - Grinding | After heat treatment where required | AGMA 14 / DIN 4 / JIS 0 | 1-32 DP | M0.8-M25 |
| Spur & helical - Power honing | Finishing route | AGMA 12 / DIN 6 / JIS 2 | 1-128 DP | M0.2-M20 |
| Spiral bevel - Cut & lap | Before heat treatment | AGMA 10 / DIN 8 | 1-10 DP | M2.5-M25 |
| Spiral bevel - Grinding | Finishing route | AGMA 12 / DIN 5 | Up to 4 DP | Up to M6 |
Important: final feasibility and achievable quality depend on gear geometry, size, material, heat treatment, datum condition, measurement method and batch requirements.
Report scope is agreed before production. The examples below show common formats, not a promise that every document is included with every order.
Records agreed dimensional characteristics and measured results against the drawing or inspection plan.

Shows measured gear-tooth geometry such as profile and helix or lead deviation for agreed characteristics.

Supports verification of selected post-heat-treatment material characteristics when included in the project plan.

Discuss Your Inspection PlanInclude dimensions, tolerances, datums, gear accuracy standard and the latest drawing revision.
State the grade, hardness, case-depth or metallographic requirements when they apply.
Identify the fit, load, mating relationship and characteristics that cannot be changed.
List the reports needed for sample approval, PPAP, incoming inspection or batch release.
Confirm prototype quantity, sampling level and whether inspection is required per lot or per shipment.
Short answers for buyers preparing a custom gear RFQ or sample-approval plan.
A gear measuring center is used for agreed tooth-geometry checks such as profile, helix or lead, pitch and runout. The exact items and standard must be defined in the inspection plan.
Yes, report formats can include dimensional results and gear profile or helix measurements. Availability and sampling should be confirmed before the order is released.
No. The report type depends on the product, order scope, drawing requirements and agreed quality documents. List required reports in the RFQ so they can be reviewed and quoted correctly.
A sample can support an initial measurement and feasibility review, but production still requires confirmation of critical dimensions, material, heat treatment, accuracy and application requirements.
Engineering reviews the gear type, size, material, heat-treatment condition, accuracy grade, datums, batch size and required records before confirming the route.
Send the drawing, sample information and required reports. PairGears will review the process route and inspection scope before quotation.
