Tooth data before method
The tooth system, tooth count, pressure angle, face width, and helical details when relevant are organized before a method is confirmed.
Gear machining services
Gear machining, built around tooth data and mounting intent.
Tooth geometry, the gear blank, bore, hub, keyway or spline, material condition, mating context, heat-treatment sequence, finish, and inspection intent all shape a useful gear review. Share the model and drawing so Pearson can organize those requirements and confirm a project path before acceptance.

This page describes common request types. Available processes, equipment, tolerances, inspection, documentation, and fulfillment are confirmed for each quote.
Overview
A clearer way to review gears and gear blanks.
A gear model can look complete while leaving out information that controls mesh and mounting. Tooth count, module or diametral pitch, pressure angle, face width, helix direction or angle when relevant, bore and hub datums, keyway or spline definition, mating-gear context, material condition, sequence, and inspection intent should be visible before a process path is selected.
Mounting geometry and datum context
Bore, hub, faces, shoulders, keyways, splines, and mating-shaft relationships help define how the gear locates and transfers torque.
Sequence and verification intent
Material condition, heat-treatment and finish sequence, functional relationships, and documentation expectations belong in the request instead of being inferred.
Fulfillment review
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.

Gear feature review
What should the model and drawing explain?
Choose a feature group to see the details that help clarify the request.
Tooth form, pitch data, and mating intent
The tooth definition should identify the system, size, count, face width, and mating context that control how the gear is expected to mesh.
- Tooth count, module or diametral pitch, and pressure angle
- Face width and helix angle or hand when relevant
- Reference geometry, mating gear, and backlash or centre-distance intent
Helpful drawing detail
Include the complete tooth data on the drawing and add mating-gear information when mesh requirements cannot be understood from this part alone.
Process fit, equipment fit, achievable tolerances, inspection, documentation, fulfillment, and timing are confirmed from the project information during quote review.

Quote workflow
From files to a confirmed gear machining path.
A short, human-managed review keeps tooth data, mounting geometry, sequence, and open questions visible before work is accepted.
- 01
Share the part
Upload the model, drawing, gear data, photos, quantity, material grade or preference, and known mating or functional requirements.
- 02
Review the gear drivers
Tooth definition, blank condition, bore and hub datums, torque-transfer features, sequence, finish, and inspection intent are organized for follow-up.
- 03
Confirm the path
Process fit, equipment fit, achievable tolerances, fulfillment, timing, and remaining questions are resolved before acceptance.
- 04
Coordinate the project
Approved files and requirements become the reference point for project communication and requirement control.
Drawing readiness
Small decisions that make a gear request easier to review.
Clear tooth, mounting, and functional intent is more useful than assuming a method or applying close requirements everywhere.
Design intent before assumptions
- 01
Provide the complete tooth system and data.
State tooth count, module or diametral pitch, pressure angle, face width, and helix angle and hand where relevant; add reference geometry and mating context when function depends on them.
- 02
Separate the tooth form from blank geometry.
Define the blank, faces, shoulders, bore, hub, and stock condition independently so mounting features and tooth requirements are not inferred from one another.
- 03
Identify the mounting datum relationship.
Show which bore, face, or hub feature locates the gear and which tooth-to-datum or runout relationships affect the assembly.
- 04
Fully define keyways and splines.
Include the governing standard or complete dimensions, fit information, length, orientation, end condition, and mating-shaft details instead of relying on the model alone.
- 05
State the material and process sequence.
Name the grade, current condition, planned heat treatment and finish, and which dimensions or features must be established before or after each step.
- 06
Tie inspection intent to function.
Identify the tooth, bore, face, datum, mesh, and mounting relationships that need verification and state the required documentation without treating every feature as equally critical.

FAQ
Gear machining quote questions.
A STEP or STP model and matching PDF drawing are a strong starting pair. Add tooth data, material grade and condition, blank and finished dimensions, bore and hub details, keyway or spline definition, mating context, quantity, timing, sequence, finish, and inspection or documentation needs when known.
State the tooth count, module or diametral pitch, pressure angle, face width, and helix angle and hand when relevant. Add reference geometry, backlash or centre-distance intent, tooth-thickness definition, and mating-gear context where those details control function.
Identify the locating bore, hub, or face, its fit and finish intent, and the tooth-to-datum or face-to-bore relationships that affect assembly. Use clear datum references instead of relying on concentric-looking model geometry.
Reference the applicable standard and fit information or provide complete dimensions. Include length, orientation, end condition, access, and mating-shaft details so the torque-transfer feature is not inferred from the model alone.
State the material grade and current condition, planned sequence, which features are final before or after each step, functional datum relationships, surface and edge requirements, and required inspection or documentation. The final scope is confirmed from the project files.
