Machining Process

How We Machine Custom Shafts

CNC turning establishes the main axis and diameters. Secondary machining, treatment, grinding, and inspection complete the specified features and performance.

1Drawing ReviewConfirm datums, fits, critical surfaces, material, and inspection needs.

2Material SetupMatch bar, tube, forging, or prepared blank to the part and quantity.

3CNC TurningEstablish the axis, journals, diameters, shoulders, faces, and profiles.

4Feature MachiningMachine keyways, splines, flats, threads, holes, grooves, and end details.

5Treatment and FinishApply heat treatment, coating, or grinding only where the specification requires it.

6Inspection and PackingVerify functional dimensions and protect finished surfaces for shipment.

Production Control

Custom Shaft Quality and Delivery Control

Before production, we lock the material, datum strategy, machining route, critical checks, finish, and packing requirements.

Drawing FirstIdentify the dimensions and surfaces that control assembly.

Process MatchedUse turning, milling, grinding, and finishing only where required.

Critical ChecksMeasure functional features during production and final inspection.

Protected ShipmentClean, identify, and protect finished shafts before dispatch.

Custom Shaft FAQ

Custom Shaft Machining Questions

What should I send for a quotation?

Send a 2D drawing or 3D model, material, quantity, tolerances, finish, and required inspection points.

When does a shaft need grinding?

Grinding is used when journal fit, roundness, runout, or surface finish exceeds normal turning capability.

When should I specify a spline shaft?

Specify splines for multi-tooth torque transfer, accurate centering, or controlled axial sliding.

How do you protect the delivery schedule?

Material availability, setups, outside treatments, inspection points, and packing are confirmed before the production date is committed.
