Where this design fits

Gap adjustment, alignment fixtures and camera or module positioning mechanisms.

What to include in the RFQ

Provide an assembly view, datum scheme and required adjustment range.

Material and acceptance

Carbon steel, 10B21, SUS304/316, aluminum, copper/brass and titanium alloy requirements can be discussed. Suitability is specific to the part, grade and process.

Define material condition, coating, critical dimensions and required inspection records. A named product family does not imply a tested load, pressure or performance rating.

RELEVANT PROCESS OPTIONS

Make the features work together.

These routes are options for technical review. The approved drawing, quantity and material determine the actual sequence.

Useful technical reading

Define the datum axis, eccentric centre and angular reference

The left view separates the mounting axis A from the eccentric centre B. The right view illustrates a separate angular reference. These are drawing relationships, not a tolerance value inferred from the outer shape.

Interface sketch — not to scale. Dimensions and acceptance follow the approved assembly drawing.

Datum axis A: define the feature that establishes the installed axis and how it is located during inspection. A threaded surface needs an agreed datum interpretation.
Centre B and offset: dimension the eccentric feature relative to A, including its size and any controlled form. Show the mating contact or follower.
Angular reference: identify the zero direction, any clocked flat or drive and the permitted adjustment range. Relate the setting to the assembled contact, not only to a loose part.

Agree the measurement setup for the specified offset and angular relationship, then trial the movement in the mating assembly. An outside-diameter screen alone does not establish eccentricity, orientation or the available adjustment once nearby parts are installed.

Specify eccentric datums and inspection positioning

Offset, reference axis and angular position

Define the offset from a named datum axis and show the orientation of flats, drives or contact faces. For an adjuster, describe the required movement and stops in the assembly. Measuring only outside diameters cannot establish eccentricity or the angular relationship that makes the mechanism work.

Review the route before fixing the quotation

For eccentric & angled head screws, review Swiss-Type & CNC Turning, Secondary & Precision Operations, CCD Vision & Dimensional Inspection against the drawing and quantity. Identify which features can be produced in the initial shape and which require a separate setup. A change to a functional shoulder, bore, drive or thread can change the proposed route as well as the inspection effort.

The drawing review should resolve offset & datum; head orientation; adjustment range. Keep material condition and finishing allowance attached to those requirements. Define the acceptance condition for critical features and approve any proposed dimensional change before comparing samples with the original assembly.

From drawing to approved samples

Provide an assembly view, datum scheme and required adjustment range. Identify the drawing revision, prototype quantity and expected repeat demand. Where the first part is based on an existing sample, separately confirm material and hidden features rather than inferring them from appearance.

The typical sampling lead time, including tooling, is approximately 10–15 days. The schedule is confirmed after drawing review and agreement on the sample specification; material availability, special treatment and inspection requirements can affect the confirmed date. Confirm when the agreed schedule starts in the quotation. Sample approval and repeat-production delivery are separate milestones.
