/ PART SHAPES

Start with Similar Part Shapes

Compare your drawing with similar part shapes before reviewing geometry, material, tolerance, finish and inspection requirements.

Straight Pins

Straight Pins

Simple turned profiles with repeatable diameters.

Stepped Shafts

Stepped Shafts

Multiple diameters, shoulders and grooves planned as one route.

Shafts With Flats

Shafts With Flats

Cross holes, flats and slots require position and burr review.

Inspection Datum

Inspection Datum

Runout-sensitive or mating relationships must be clear before quotation.

/ SHAFT GEOMETRY

Long Geometry Needs a Datum-Based Read

Shaft and pin drawings are reviewed along the part length, where diameter changes, shoulders, grooves, flats and cross holes affect route and inspection.

Shaft feature layout

Diameter

OD stack, datum and tolerance callouts.

Shoulder

Axial locating faces, shoulders and transitions.

Groove

Grooves, retaining features or seal-related details.

Cross Hole

Cross features, secondary operations and burr control.

Runout

Datum reference, runout concern and inspection method.

/ FEATURE SELECTOR

Choose the Feature That Drives the Drawing

Select the feature that matters most to the assembly. The route, inspection plan and quote change when the critical feature changes.

Stepped Profiles

ACTIVE FEATURE

Stepped Profiles

Multiple diameters and shoulders are reviewed as one rotational process when length, tolerance and material allow stable production.

/ MANUFACTURING FIT

Fit, Review or Alternate Route

Use this table to decide what must be confirmed before quoting the part for repeat production.

Requirement
Part Family / Route
Buyer Value
Best fit
Pins, shafts and stepped rotational parts
Repeat diameters and shoulders suit turning-led production.
Swiss candidate
Small diameter, long or slender pins
Guide-bushing support may reduce deflection where geometry fits.
Needs review
Runout, coaxial or mating relationships
Drawing-level CTQs should be confirmed before process commitment.
Secondary route
Cross holes, flats or slots
May require coordinated secondary machining.

/ RFQ CHECKLIST

Details That Change the Quote

A useful RFQ makes the manufacturing constraints clear enough to review route, inspection method and repeat-production fit.

Diameter Stack

OD callouts, tolerances, datums and critical mating diameters.

Shoulders / Grooves

Axial faces, shoulders, retaining features and transition radii.

Cross Features

Hole, flat or slot locations relative to datum and assembly direction.

Production Fit

Material, quantity and repeatability expectations.

/ FROM DRAWING TO PART

One Review Path from Drawing to Production

After the part family is clear, the review path focuses on geometry, CTQs, sample validation and repeat-production control.

Drawing Review

Confirm geometry, tolerances, material, finish, quantity and CTQs.

Route Selection

Select Swiss turning, CNC turning or a combined secondary-operation route.

Sample Path

Plan sample review; typical prototype timing is around 7 days when geometry, material and scope allow.

Production Plan

Carry confirmed CTQs and inspection requirements into repeat production; 500+ pcs is a strong production-fit range.

Inspection Release

Check drawing-defined CTQs, edges, finish and packing requirements before shipment.

/ PROCUREMENT FAQ

Questions Before RFQ

Discuss Your Part ->

Swiss turning should be considered when the part is small in diameter, long or slender, and guide-bushing support may help control deflection near the cutting zone.

Yes, when their position, burr condition and inspection expectations are defined. They may be handled with live tooling or secondary operations depending on geometry.

Typical tolerances around ±0.01 mm can be reviewed on suitable features, but feasibility depends on material, geometry, length and inspection method.
