Custom Metal Machining From Drawing to Part

Custom metal machining turns a 2D/3D drawing into a finished metal part: milled, turned, ground or EDM-cut to spec, for engineers and procurement teams sourcing prototypes or production runs.

DEK has machined metal parts for 20+ years, producing 1.2M+ parts annually for 2,300+ OEM clients. One titanium bracket or a running stainless steel batch runs on the same ISO-certified line, with no minimum order quantity.

Why Source Metal CNC Machining From DEK

Engineer-reviewed manufacturing behind every quote, documented quality control and hard-alloy experience on one production floor.

  • Scale With Accountability

    1.2M+ parts machined per year for 2,300+ OEM clients, with a 98.6%+ on-time delivery rate across prototype and production orders.

  • No Minimum Order Quantity

    A single bracket and a multi-thousand-unit order run on the same line, and both get engineer attention rather than automated pricing.

  • Certified for Regulated Work

    ISO 9001, ISO 13485 and AS9100D, obtained through TUV, cover medical, aerospace and industrial parts under one supplier from prototype to production.

  • Engineer-Reviewed Quotes

    Drawings are checked by hand for tolerance, fixturing and material behavior (heat-treatment distortion, grinding allowances, thin-wall deflection) before pricing.

Hard-Alloy Machining Experience

Sourcing usually comes down to holding tolerance on the actual material ordered. Our engineers program and inspect Ti-6Al-4V, Inconel 718, 17-4PH and 316LVM alongside common aluminum and mild steel grades.

Metal Machining Processes and Tolerances

Milling, turning, EDM, grinding and gear cutting on 20+ metal alloys, with 50+ materials in total on one production floor.

  • Metal Selection by Cost Tier

    Relative cost follows machinability. A single order can mix materials, such as an aluminum housing with a stainless steel shaft.

    • Aluminum: default for lightweight, cost-driven parts
    • Titanium for strength-to-weight in aerospace and medical
    • Tungsten steel in the top tier with Inconel

Custom Metal Machining vs. Other Processes

Machining fits solid metal parts that need tight tolerance at any volume. Orders mixing metal and plastic run through our general machining service.

Metal Parts for Regulated Industries

Aerospace, medical device, robotics, semiconductor and energy programs run on the same certified line, from prototype brackets to production housings.

Metal Part Features and Machining Challenges

Typical metal part types and the material and geometry problems our engineers resolve before the first cut.

  • Housings and Brackets

    Milled on 3-, 4- and 5-axis machines; see our machined brackets for prototype and production runs.

  • Shafts and Pins

    Turned on standard and Swiss-type lathes, bar-fed or chucked; see custom shafts for round parts.

  • Shaft-Bore Fits

    Fit-critical features such as shaft-bore fits and coaxiality held to ±0.005 mm, confirmed against the drawing at quote.

  • Features Under 10mm

    Micro and small parts held to ±0.003 mm through micro machining and Swiss turning support.

Common Challenges We Handle

  • Hard-to-Machine Alloys

    Ti-6Al-4V, Inconel 718 and tungsten steel cut slowly and wear tools fast; see superalloy machining for validated methods.

  • Thin-Wall Deflection

    Reviewed by hand at quote; wire and sinker EDM cut thin walls and internal geometry without distorting the part.

  • Heat-Treatment Distortion

    Distortion and grinding allowances are planned at quote, then grinding removes the final stock machining alone cannot hold.

  • Hardened Tool Steel

    EDM cuts hardened tool steel where a cutting tool would struggle, for die and mold parts.

ISO-Certified Metal Machining

Every job runs through a documented quality management system, not a final visual check.

Frequently Asked Questions

Answers on cost, metals and order quantities for custom metal parts.

How much does custom metal machining cost?
Cost scales mainly with material and complexity. Aluminum and mild/carbon steel are cheapest; stainless, brass and alloy steel are mid-range; titanium, Inconel and tool steel cost most because they cut slowly and wear tooling. Tight tolerances, small features and low quantities add cost.
What metals can you CNC machine?
DEK machines 20+ metals: aluminum, stainless steel, titanium, brass, bronze, copper, alloy and tool steel, Inconel, Invar, Kovar, magnesium and tungsten steel, alongside engineering plastics for mixed-material orders.
Is there a minimum order quantity?
No. DEK accepts orders from a single prototype through full production runs on the same line, so a design can move from a first part to volume without switching suppliers or requalifying from scratch.
