Capabilities
  • 3- and 4-axis CNC milling
  • CNC turning
  • Aluminum, steel, engineering plastics
  • ±0.001″–0.005″ typical
  • Prototype → production runs
  • Deburring + finishing
Manufacturing focus
  • Quote + DfM review
  • Fixture design
  • Programming + setup
  • First-article inspection
  • CMM verification
  • Deburring + finishing

Tolerances on paper are a starting point. Repeatability across batches is the deliverable.

Engineering process

CNC Machining in 3 phases

A structured engineering workflow — same team across every phase, no handoffs.

  1. 1

    Quote + DfM review

    Drawing reviewed against shop capability — flagged for tool access, fixturing, and post-process needs.

  2. 2

    Programming + setup

    Toolpath programmed for the production fixture, not just first article.

  3. 3

    Inspect + ship

    First-article inspection report on every job · CMM-verified critical features.

Featured case study

Gen 3 Cam Covers

Aluminum cam-cover program with CNC-machined geometry, custom badge inlays, and post-machining finishing — delivered ready for the customer line.

Gen 3 Cam Covers
Challenge
Produce show-quality aluminum cam covers for two distinct customer variants (Pyramid and Shelby Cobra), with custom badge inlays and finish quality that matches a premium engine build.
Engineering solution
CNC-machined aluminum geometry, badge inlay tooling for both Pyramid and Shelby Cobra variants, post-machining and finishing pipeline under one supply chain. Quality controlled to fit on the customer assembly line.
Manufacturing outcome
Finished and ready to fit. Both variants shipping in support of the customer's build program.

Why M² engineering

Why companies trust M² Engineering

  • Tight + repeatable

    Toolpaths and fixtures qualified for repeat runs — the second batch matches the first.

  • Plastic + metal

    Engineering plastics (PEEK, Delrin, Ultem) machined to the same precision as metal.

  • Post-machining included

    Deburr, anodize, chemical-finish, or thread-form — done before parts ship.

  • Direct access

    Communicate directly with experienced engineers throughout the project.

  • 3Decades of combined experience
  • $120MManufacturing company built
  • 25+Years engineering leadership
