Engineering Support

Assembly Requirements We Review Before Production

Reviewing the assembly before machining helps identify fit, tolerance, hardware, and revision issues before they cause assembly problems.

Assembly Drawing

Review the overall assembly structure, mating relationships, and important assembly dimensions.

BOM & Revision

Confirm component quantities, purchased hardware, part numbers, and current drawing revisions.

Fit Requirements

Review clearance, interference, locating features, and other important mating conditions.

Acceptance Criteria

Confirm agreed visual, dimensional, functional, and inspection requirements for the completed assembly.

Simplify Your Supply Chain

Reduce the Number of Suppliers You Need to Manage

Traditional Supply Chain

Multiple vendors can mean more purchase orders, more coordination, longer scheduling chains, and more handoffs of responsibility.

  1. Machining Supplier
  2. Hardware Supplier
  3. Secondary Process Supplier
  4. Assembly
  5. Inspection
  6. Customer

Quality Assurance

Check the Completed Assembly, Not Only the Parts

Individual parts may meet their drawing requirements while the completed assembly still needs to be checked as a system.

  • Component Verification

    Confirm the correct components and required hardware are present.

  • Fit & Alignment

    Check mating conditions, alignment, and basic movement where applicable.

  • Hardware Check

    Verify specified fasteners, inserts, and purchased components are installed.

  • Visual Inspection

    Check the completed assembly for obvious damage, contamination, or assembly issues.

  • Functional Check

    Perform agreed basic movement, engagement, or fit checks where applicable.

  • Inspection Records

    Provide inspection documentation when included in the agreed scope.

Frequent Questions

Assembly FAQ

Can you assemble CNC machined parts before shipment?

Yes. We can combine machined components and specified hardware before shipment. Assembly drawings, fit requirements, and the agreed scope are reviewed before production.

Can you source standard hardware for the assembly?

Yes. Standard hardware can be sourced according to your BOM or an agreed specification. Part numbers, quantities, and any proposed substitutions are confirmed before procurement.

Can you install bearings, bushings and threaded inserts?

Bearings, bushings, pins, and threaded inserts can be installed where specified. The fit, installation method, and part geometry are reviewed before confirming the work.

Can assembled parts be inspected before shipment?

Yes. The completed assembly can be checked for component presence, fit, alignment, visual condition, and agreed basic functional requirements. Inspection documentation can be provided when included in the agreed project scope.

Can machined parts and assemblies be supplied under one purchase order?

Yes. Machining, purchased hardware, the agreed assembly scope, and inspection can be coordinated under one purchase order. Partner-supported secondary processes and delivery requirements can also be included where applicable.

What files are needed for an assembly quotation?

Send the assembly drawing, individual part drawings, 3D models, BOM, hardware specifications, and inspection requirements you have. Bundle multiple files, including spreadsheet BOMs, into a single ZIP file of up to 20 MB. Incomplete information can be reviewed with our team.
