Manufacturing Capabilities and Services


Our team of programmers and machinists utilize the latest CNC milling technology, tooling and machining processes to manufacture tight-tolerance milled parts.

Defiant CNC takes great care in fixture design, tooling selection and programming to create a manufacturing process that allows for high precision parts while continuously improving setup and run times.

Whether your company uses CAD models, 2D blueprints or imperial or metric dimensions, we can provide CNC milling services to suit your needs.  We are capable of machining parts using 3 axis and 4 axis mills with table sizes up to 20” x 40”.


Defiant CNC provides CNC turning services capable of receiving a solid chunk of raw material and – without any operator handling – can turn, mill, drill, bore, engrave, tap and thread a ready-to-ship, finished product.

We have comprehensive CNC turning capabilities from .020″ to 6″ diameter and lengths up to 28″ and produce parts with tolerances of ±0.0002. 

Our experienced team can quickly setup and run jobs in almost any material and lot size, so customers don’t need to spend the time to maintain and deal with multiple turning suppliers on their projects.

Engineering and CAD

Our in-house engineering team is able to offer their experience and knowledge in design-for-manufacturing.

We are readily available to assist our customers in taking their parts from conception to final product, and strive to be a one-stop shop to offer the resources needed to streamline manufacturing product development.

Our engineering services consist of providing designs for new components, products, and equipment for our customers.  Engineering services include part and material specification, manufacturing drawings, product manuals, and manufacturing support and/or certification documentation.

Laser Engraving

Our Boss FMS laser engraver allows us to laser etch your parts.  Whether you need part numbers, serial numbers, images or logos laser engraved on your parts; Defiant CNC has your laser engraving services covered.

Technical Drawings

Technical drawings visually communicate how something functions or is constructed.  They are essential for communicating ideas in manufacturing.  Our prints consist of 2D orthogonal projections of the part or component they describe.  If you need a 2D drawing created from a solid model or an actual product/part, Defiant CNC can create these technical drawings for you.


We offer a variety of secondary processes to put the finishing touches on your parts. These may be handled internally or via outside vendors depending on the project. 

  • Plating (Including Anodizing)
  • Tumbling
  • Heat Treating
  • Wire EDM
  • Ultrasonic Cleaning
  • Bead Blasting
  • Welding and Fabrication
  • Assembly
  • Inserts (Helicoils, Rivet Nuts, etc.)

Quality Control

Everything that we manufacture is subject to stringent quality measures; we employ advanced inspection techniques and utilize a traceable calibrated instrumentation system.  Our operation is geared for production from prototype to low-volume production runs.

Inventory Management

We strive to get highly precise and custom parts to our customers quickly, when they need them and in the quantity required. 

We utilize our proprietary Enterprise Resource Planning system to track inventory and offer robust inventory management services such as split shipments, blanket orders, timed on-dock deliveries.  We work with your supply chain to establish a plan that fits your project timelines and inventory needs.


CNC Machining on Demand

Order high-quality custom prototypes and end‑production parts.  We have comprehensive CNC milling and CNC turning capabilities to manufacture all your tight-tolerance parts.

request for quote

Start by sending us a solid model and/or print of the part that you would like manufactured.  Then, we will determine the manufacturability of your part.

Quotation Process

You will receive a quote based on the type of material, difficulty of manufacturing the part, number of operations and required turnaround time.


Once you’ve placed an order, you’ll always be able to check on its status as it moves through production.


When production is completed, your parts will be checked in our quality control lab.  You can request a first article inspection where you will receive documentation on your part's dimensions and the processes used to check your part.



You will be able to track your parts once they are shipped


Take your ideas from design to production


CAD/CAM stands for computer-aided design and computer-aided manufacturing.   CAD/CAM software is used to design and manufacture prototypes, finished products and production runs.  After a part is designed, we specify the types of tools that will be used to make the part and create a g-code program.

CNC Machining

CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery.  We upload g-code programs (created using CAD/CAM software) onto CNC mills and CNC lathes to create parts out of various materials.

Quality Control

Quality control is a system of maintaining standards in manufactured products by testing a sample of the output against specifications.  We employ various measuring instruments (CMM, micrometers, optical comparator, gauge blocks/pins, etc) to verify the accuracy of the parts we make for our customers.


CAD Design on Demand

Order an accurate 3D model or an entire assembly that can subsequently be used to machine or 3D print your part(s).

request for quote

Start by telling us what type of part(s) you would like modeled.  

Quotation Process

You will receive a quote based on the number of components to be modeled, difficulty of the design and required turnaround time.

Design process

Once you’ve placed an order, you’ll always be able to check on its status as it moves through the design process.


We can also create a 2D print of your 3D model.


You will receive the appropriate documents in the file types you request once your design is complete. 


Take your ideas from concept to design

3D modeling

3D modeling is the process of developing a mathematical representation of any surface of an object in three dimensions via CAD software.  These models can subsequently be used to manufacture parts using CAM software and CNC machines or 3D printers.

assembly Modeling

Assembly modeling is a technology and method used by computer-aided design and product visualization computer software systems to handle multiple files that represent components within a product. The components within an assembly are represented as solid or surface models.

technical drawings

Technical drawings visually communicate how something functions or is constructed.  Technical drawing is essential for communicating ideas in manufacturing.  Our prints consist of 2D orthogonal projections of the part or component they describe.
