Drawing-led purchasing

Guide pillar: agree the complete supply scope

Define the guide and mounting interfaces

Show the mating guide bore and the assembly section that establishes the pillar position. Identify the working length, entry direction and surfaces that provide guidance. Define the limits on the controlled drawing and give each feature a reference for the quotation.

Locate the collar and its seating face relative to the guide surface. Show any adjacent clearance, edge condition and assembly access. If the guide slides in a bushing, provide the mating part drawing or interface limits for review.

Specify the internal thread and usable engagement

Identify the thread standard, size, pitch, tolerance class, usable full-thread depth and the mating screw. For a blind tapped hole, distinguish the thread runout, drilled depth and clearance at the bottom. Give the assembly team a clear engagement requirement.

Review the blind tapped hole guide when setting the usable depth. The screw, assembly procedure and any locking feature should be listed separately when they are included in the requested supply.

State the stainless steel grade and final condition

The shown reference identifies stainless steel. Specify your actual grade and material condition on the released drawing, together with any surface treatment and the dimensions that apply in the delivered state. Ask for the material or treatment records required by the order.

Do not rely on a visual reference to set a grade or finish. If an alternative is proposed during quotation, keep it as a separate decision and update the controlled specification before sample approval.

Agree sample measurements before release

Name the guide diameter, useful length, collar location and thread characteristics that need recorded results. State the drawing datums and inspection condition; discuss access, part support and the thread gauge or method with the supplier.

If a fit or assembly trial is required, identify the mating bushing and fastener, installation condition, procedure and acceptance owner. Use the inspection requirements guide to include those deliverables in the quotation.

Keep the quotation and repeat order comparable

Send the same drawing revision, quantities, material grade, final condition and required records to each potential supplier. Distinguish the guide pillar itself from separately identified hardware or assembly work, and ask for proposed alternatives and exclusions.

Record the accepted sample and any approved change before a repeat order. Compare a related stepped shaft reference for shoulder and guide geometry, then send the controlled files through the drawing-led enquiry.

Questions before requesting a machining quotation

What material is shown in this guide pillar reference?

The published reference identifies stainless steel. Specify the actual grade, material condition and any treatment for your own drawing before quotation.

What dimensions should accompany a guide pillar enquiry?

Provide the guide diameters and lengths, collar location, seating face and internal thread. Include the mating bore and the drawing references that control assembly.

How should I specify a blind internal thread?

State the thread standard, pitch, tolerance class and usable full-thread depth. Distinguish the thread runout and drilled bottom clearance from the required engagement.

Can a mating bushing be included in a sample review?

Identify the bushing and its drawing or interface limits, the intended assembly condition, the trial procedure and who accepts the result. List it separately in the requested supply scope.

What inspection records should I request?

List the guide, collar and thread characteristics that need results, with the applicable drawing revision, datums, measurement method and sample identity.

How are quantities and lead time agreed?

Include sample and production quantities and your target date in the RFQ. The quotation confirms the reviewed scope, required records and schedule for that order.

DEFINE YOUR PART

What needs to
be in your drawing?

Use the released drawing to identify the guide, collar, thread, material condition and feature-level records requested with the order.

  • Mating diameters and fit designation
  • Datum scheme, runout and straightness
  • Thread, groove and edge requirements
  • Drawing number, revision, units and material grade.
  • Surface treatment, sample quantity and repeat-order needs.
Use the complete RFQ checklist
01 / REVIEW

Resolve the requirements.

Share your drawing and the features that affect function. Agree material, process scope, inspection and commercial conditions.

02 / SAMPLE

Define what approval means.

Agree the sample quantity and measurements or assembly checks required for acceptance. Record the drawing revision used.

03 / REPEAT

Control the next order.

Retain the approved specification and packaging requirements. Review design, material or finish changes before repeat production.
