CNC Machining.
Machined with precision. Delivered with speed.
Precision-machined metal and plastic components — globally sourced and program-managed. MES doesn’t just source the part. We manage the quality, tolerances, and supply chain that deliver it.
What is CNC machining?
CNC machining — Computer Numerical Control machining — is a subtractive process in which computer-controlled cutting tools remove material from a solid workpiece to produce a precisely dimensioned metal or plastic component. CNC programs translate CAD models into exact tool paths, delivering highly repeatable production of complex parts to tight tolerances.
Because the same program runs identically across thousands of cycles, CNC machining delivers the dimensional consistency that demanding automotive, energy, and industrial programs require — from a single prototype to volumes above 100,000.
CNC processes we support
CNC Turning
The workpiece rotates against a stationary cutting tool to produce cylindrical features — diameters, bores, threads, grooves, and tapers.
Rotational parts — shafts, hubs, bushings, pins, and rollers.
CNC Milling
A rotating tool cuts a fixed workpiece to produce prismatic features — flat faces, pockets, slots, holes, and contoured 3D geometry across 3-, 4-, and 5-axis centers.
Complex, multi-sided, and tight-tolerance components.
Use turning for rotational parts and milling for prismatic or complex geometry. Many components need both — plus grinding, boring, drilling, and tapping. MES matches the process, machine, and supplier to your part’s geometry, tolerance, and volume — before the first chip is cut.
5-axis machining moves the tool along five simultaneous axes, cutting complex multi-sided features in a single setup. Fewer setups means better accuracy, shorter cycle times, and geometries impossible on 3-axis machines.
Materials we machine
Material selection is driven by mechanical load, weight target, corrosion exposure, thermal requirements, and cost — evaluated with your team during quoting, not after.
Design & engineering support (DFM)
Our engineers support design for manufacturability from concept through launch — reducing redesigns and hitting your specifications the first time. Typical guidance we provide:
Tolerances & GD&T
We flag where tolerances are truly critical so cost isn’t spent tightening features that don’t need it.
Material selection
Balancing machinability against mechanical, thermal, and corrosion requirements.
Feature & tool access
Designing around standard tooling and reachable geometry to control cost and cycle time.
Threads & holes
Standard sizes and depths reduce tooling changes and lead time.
Surface finish
Specifying finish only where the application requires it.
First-article & CAM review
Toolpaths and first articles verified before production release.
One partner. The finished part.
MES manages the full component — not just the machining. One partner delivers the finished, inspected, ready-to-install part.
Verified at the source
MES embeds engineers and quality specialists inside supplier facilities — measuring quality at every production stage, not just at final inspection.
The MES difference
Every account gets a dedicated supply chain specialist and planner who own quality, inventory, and on-time delivery as one program.
Globally sourced CNC machining
MES maintains active machining suppliers across the key manufacturing hubs of Mexico, Europe, Japan, India, China, and Vietnam — optimizing lead time, cost, and logistics per program, and enabling China+1 strategies for customers diversifying risk.

Nearshore machining in Saltillo, Mexico
MES operates its own capacity — Metrics Works, a company-operated machining facility in Saltillo, Coahuila, at the heart of Mexico’s largest automotive cluster. It gives North American OEMs a nearshore alternative to overseas machining: shorter lead times, simpler ground-freight logistics, USMCA-aligned sourcing, and time-zone-aligned engineering.

Frequently asked questions
CNC turning rotates the workpiece against a stationary tool to create cylindrical features — diameters, bores, threads, and tapers — ideal for shafts, hubs, and pins. CNC milling moves a rotating tool against a fixed workpiece to create prismatic features such as flat surfaces, pockets, slots, and 3D contours. Many components require both.
For automotive programs, MES sources through IATF 16949-certified supplier facilities and supports the full automotive quality chain — PPAP, control plans, FMEA, and material certifications — to meet OEM and Tier-1 requirements. MES has held ISO 9001:2015 certification since 2009.
Yes. MES operates Metrics Works, a company-operated machining facility in Saltillo, Coahuila — in Mexico’s largest automotive cluster — offering shorter lead times, simpler logistics, USMCA-aligned sourcing, and time-zone-aligned engineering support.
Standard tolerances are typically ±0.001″ (±0.025 mm); tight-tolerance features can be held to ±0.0005″ (±0.013 mm) or better. Surface finishes range to 32 Ra or finer, with critical dimensions verified at the source using CMM before parts ship.
Aluminum (6061, 7075), carbon and alloy steels (1018, 4140, 4340), stainless steels (304, 316, 17-4 PH), ductile and gray iron, brass, copper, magnesium, titanium, and engineering plastics including Delrin, PEEK, nylon, and UHMW.
MES embeds quality engineers inside partner facilities. Dimensional accuracy is verified against your drawing with CMM equipment, first article reports are reviewed, and critical features are confirmed before parts ship — not discovered at your dock.
Prototypes are often 1–3 weeks; production orders typically 4–10 weeks. Nearshore capacity at Metrics Works and warehousing near your facility can significantly compress replenishment lead times.
