Our Milling Capabilities

Choosing the right materials, finishes, and after-production services can make the difference between reliable parts and parts that don’t work and don’t sell. At Technox Machine & Manufacturing, Inc., we work hard to provide an extensive range of milling capabilities—including a variety of material, finish, and additional service options—to allow our customers to streamline their production process and reduce their production costs.

Our Materials Capabilities

We have in-depth expertise working with most types of metal including, high-temperature, high-strength alloys. The metal materials we mill include:

  • Aluminum
  • Brass
  • Bronze
  • Cast Iron
  • Copper
  • Nickel and nickel alloys (such as Hastelloy and Inconel)
  • Stainless Steel
  • Steel

We also provide milling capabilities for plastic parts.

Our Finishing Capabilities

The finish of a milled part significantly influences its longevity, functionality, and reliability. At Technox, we offer the following finishing services:

  • Anodizing. The anodizing process coats a metal component with an electrolytically formed oxidized layer. This layer stops the rest of the part from oxidizing because it forms a hard barrier against oxygen and contaminants.
  • Black oxide. During this process, operators dip parts into a black oxide bath. The chemicals convert the top layer of material to a more matte and corrosion-resistant surface.
  • Painting. Painting creates a layer of protection against chemicals, corrosion, and physical damage. Additionally, different paint colors can facilitate the organization and identification of components after production and increase the aesthetic value of the individual parts.
  • Plating. Many industrial parts are plated. The plating process coats parts in a thin shell—i.e., plate—of another metal to create a surface that resists damage.
  • Priming. Priming is similar to painting. This additional step prepares the surface for future painting operations to provide stronger adhesion and protection.
  • Powder coating. Powder coating finishes adhere to the surface of a component. This dry finish is often used as an alternative to painting. Different powder mixtures can also provide different protective and other functional attributes.

Our Size and Tolerance Capabilities

Our milling equipment can handle components of up to 336 inches (28 feet) in width, 113 inches (9 feet, five inches) in length, and 84 inches (7 feet) in height. We can establish and maintain tolerances of ± 0.0005 inches on even the largest of workpieces.

Our Production Volume Capabilities

We offer milling capabilities for prototype to medium volume runs.

Additional Machining Processes

No matter how complex your part design is, we have the machining capabilities to bring it to life. In addition to our milling services, we offer the following machining processes:

  • Boring
  • Broaching
  • Counterboring
  • Countersinking
  • Drilling
  • Facing
  • Gear hobbing
  • Knurling
  • Parting/cutting
  • Pocketing
  • Profiling
  • Reaming
  • Splining
  • Tapping
  • Threading

Additional Services

To support our machining operations, we also offer several post-fabrication services to ensure your order is finished and shipped according to your company’s needs. Our other services include:

  • Testing. We offer testing services—including hardness, dry penetrant (leak), and surface finish testing—to ensure your parts are made to the proper manufacturing and performance specifications.
  • Welding and repair. We can weld or repair parts as needed.
  • Assembly or kitting. These services allow for better logistics management throughout the supply chain and a more streamlined production process.
  • Custom packaging. Custom packaging reduces the amount of time it takes the final product to reach distribution centers, retailers, and customers.

An Overview of CNC Milling & Planer Milling

Milling: An Overview

All of our CNC vertical and planer milling operations are performed in-house at our Chicago facility, which is equipped with:

  • Planer mills
  • 3-axis and 4-axis CNC vertical machining centers
  • High-capacity forklifts
  • 35 individual pieces of lifting and hoisting equipment

Altogether, this equipment allows us to handle components weighing up to 15 tons and produce virtually any milled part design.

CNC Milling

CNC milling is a subtractive manufacturing method. It removes—rather than adds—material from a workpiece to produce the final part or product.

How It Works

CNC milling machines employ a rotating cutting tool that drills or cuts through substrates, such as wood, metal, and plastics. The machine holds the cutting tool (or tools) on a series of spindles that allow the tool to cut into the workpiece at different angles and along different axes to achieve almost any part design.

Depending on the type of milling machine employed, the milling operation can be manual or automatic—i.e., the movement of the cutting tool(s) and spindle(s) are controlled manually by operators or by computer numerical control (CNC) components. In the latter case, the CNC machines follow machine commands translated from CAD or CAM design files.


Machining processes, such as milling, offer many distinct advantages. As they remove material instead of adding it, there aren’t layers of added material or potentially weak connective joints. Instead, the piece is a single, solid part.

CNC milling is advantageous because:

  • It’s safe. CNC tools require some human oversight but no human operation. This process quality keeps workers away from sharp tools and heavy parts, which reduces the risk of injury.
  • It’s accurate. CNC milling follows very specific instructions, allowing it to produce part after part with little to no variation. As most CNC milling equipment—including ours—has three or four axes, it can easily follow intricate part designs without error.
  • It’s fast. Automated equipment almost always increases the speed of any manufacturing process because the machines can work faster and continuously. CNC milling is even faster than other machining processes because the machines employed have multiple spindles to create cuts simultaneously.

Applications and Industries

Manufacturers use CNC milling for rapid tooling, rapid prototyping, and end product production applications. In these applications, the process finds use across a wide range of industries including:

  • Aerospace
  • Automotive
  • Defense
  • Consumer products
  • Electronics
  • General industrial
  • Medical and dental
  • Robotics

Planer Milling

Planer milling equipment makes linear cuts to shape the outside of the workpiece or to cut grooves and notches. Unlike CNC milling equipment, which moves the cutting tool(s), planer milling equipment moves the workpiece back and forth against the cutting tool(s).


At Technox, our planer milling equipment can produce parts up to 336 inches (28 feet) in width. We guarantee tolerances within 0.0005 inches of the requested specifications. We can process planer milling orders on the following materials:

  • Aluminum
  • Brass
  • Bronze
  • Cast Iron
  • Copper
  • Nickel
  • Stainless Steel
  • Steel

Applications and Industries

Planer milling can produce a wide variety of industrial parts. At Technox, some of the typical parts we produce using planer milling include castings, dial plate drums, rings, segments, and shafts.

We’re proud to serve the following industries with our planer milling capabilities:

  • Automation
  • Bulk conveying
  • Food processing
  • Packaging
  • Oil & pipeline
