Quality

Certified production on every run

3-axis CNC machining programs run at ISO 9001 and IATF 16949 certified facilities with first-article inspection on every new part. Dimensional reports and material certifications ship with every order so your receiving dock and quality audit are covered.

  • ISO 9001 and IATF 16949 certified facilities
  • First-article inspection with a dimensional report on every new part
  • In-process inspection against your approved drawings
  • Certificate of Conformance and material certification with every shipment
Cost

Landed cost, not a list price

3-axis is the cost-efficient backbone of a machining program. When geometry allows X, Y, Z motion to reach every feature, there is no reason to pay 5-axis rates. Redstone quotes landed cost, with programming, fixturing, freight, and duties in the number before you see it.

  • Around 20% average landed-cost savings vs domestic-only, based on internal comparisons
  • Programming, fixturing, freight, and duties quoted up front
  • Volume tier pricing on repeat programs
  • No offshore quote desk between you and the production line
Fit

Is this a fit?

3-axis machining is the right lane for parts whose features are accessible from three orthogonal directions. Brackets, plates, housings with machined faces, and prismatic components are the strongest fits. If your geometry requires simultaneous tilting or compound-angle cuts, our engineering team flags that at the feasibility review and routes to 4 or 5-axis instead.

  • Prismatic parts, brackets, plates, and flat-feature housings
  • Hardware OEMs and Tier 1 suppliers with volume production programs
  • Parts that do not require undercuts or compound-angle simultaneous motion
  • Engineering-led teams working from released CAD and GD and T
Parts built for production

What we produce

Redstone supports production metal parts across automotive, electronics, industrial equipment, and consumer hardware programs.

Structural brackets and mounting hardware

Structural brackets and mounting hardware

Prismatic aluminum and steel brackets with drilled, tapped, and milled features produced under ISO 9001 controls with dimensional documentation on every batch. Suited to automotive Tier 1 and industrial equipment programs.

Machined plates and tooling fixtures

Machined plates and tooling fixtures

Flat plates with precision-bored holes, pockets, and slots held to ±0.001 inch for use as tooling bases, fixture plates, and sub-assemblies where consistent reference surfaces are critical.

Housing covers and access panels

Housing covers and access panels

Machined aluminum and stainless covers, lids, and access panels for electronics enclosures and industrial housings, with drilled patterns and seating surfaces held to drawing and shipped with material certification.

High-volume repeat production parts

High-volume repeat production parts

3-axis is the preferred axis configuration for volume runs on prismatic geometry. Lower cycle time per part and simpler fixturing mean predictable unit cost at volume, with SPC on repeat programs for run-to-run consistency.

From quote to production

A five-step process, documented at every handoff

From initial drawings to final delivery, Redstone keeps each stage clear, documented, and aligned with production requirements.

Each handoff is documented. No stage moves forward until drawings, materials, and production requirements are confirmed with the customer.

Frequently asked questions

Don’t see your question? Request a quote and our engineering team will answer it.

What is 3-axis CNC machining?

3-axis CNC machining moves the cutting tool across three linear axes, X, Y, and Z. The machine can reach any point on a flat, stepped, or profiled surface accessible from above or from a single side. For parts where all features are reachable without tilting the workpiece, 3-axis is the most cost-efficient axis configuration. If your part has features on multiple non-parallel faces or requires compound-angle cuts, our engineering team will recommend 4 or 5-axis at the feasibility review.

When does a part need 4 or 5-axis instead of 3-axis?

If a part has undercuts, features on more than one non-parallel face, or compound-angle surfaces that a straight vertical tool cannot reach, it needs 4 or 5-axis motion. Our engineering team reviews your CAD at the feasibility stage and recommends the right axis configuration for your geometry and tolerance requirements.

What tolerances can you hold on 3-axis programs?

Standard tolerance on 3-axis programs is ±0.001 inch. Tighter tolerances are reviewed against the specific feature and the inspection method at the feasibility review and confirmed in the quote.

What materials do you machine?

We machine aluminum 6061 and 7075, stainless 303 and 316, mild steel, titanium Grade 5, brass, and engineering plastics. If your part calls for a specific alloy or temper, our engineering team confirms availability and machinability at the feasibility review.

What are your standard lead times?

Standard production lead time is 4 to 8 weeks from approved drawings, with first-article timing confirmed at the quote stage. Rush programs are reviewed case by case.

How do customs and delivery work?

We are the importer of record and manage customs clearance, then coordinate freight to your dock with tracking. Duties and freight are quoted up front so there is no surprise on the invoice.
