3-axis vertical milling is the service that runs the most hours on our floor. We use it for everything that doesn't require rotary motion: brackets, plates, fixtures, mounting blocks, manifolds, housings, and the long tail of one-off parts that keeps a Michigan tool-and-die ecosystem running. All of it on vertical machining centers (VMCs) tuned for tight tolerances and clean surface finishes.

Every program is written by the same machinist who'll run it. That sounds obvious; it isn't, at most shops. It means a part that's a tooling nightmare gets flagged on Tuesday morning instead of the Friday after the job is on the floor.

We mill aluminum (6061 and 7075), the stainless family (303 / 304 / 316), tool steels (4140, A2, D2), brass, copper, and engineered plastics including Delrin and UHMW. Finishing (anodizing, plating, black oxide) is handled through trusted Michigan partners.

Typical applications

  1. 01Custom brackets and mounting plates for industrial automation builds
  2. 02Housings and enclosures for low-volume electromechanical products
  3. 03Workholding fixtures and soft jaws for in-house and outside shops
  4. 04Manifold blocks for hydraulic and pneumatic assemblies
  5. 05Validation parts and tooling inserts for Tier 1 automotive programs

Common Questions

Questions buyers and engineers actually ask.

A 3-axis mill moves the cutter in X, Y, and Z. A 4-axis adds a rotary table, so the part rotates under the cutter. For straightforward prismatic parts like plates, brackets, and blocks, 3-axis is faster and cheaper. For parts with features on multiple sides or rotational geometry, 4-axis cuts setups (and cost) by avoiding refixturing.
One piece. We quote and run single prototypes daily. Most of our 3-axis work falls between 1 and 200 pieces; we'll quote larger runs on request.
STEP and IGES for 3D models, DWG and DXF for 2D drawings, and PDF for everything else. If you only have a sketch on grid paper, send a photo and we'll come back with what we need.
Most 3-axis quotes go out within one business day. Complex projects (high quantities, exotic materials, unusual geometry, or specialized finishing) may take 2–3 days. If we need more time on a specific job, we'll let you know when we receive your RFQ rather than leaving you to wonder.
