CNC Machining Capabilities

Our in-house CNC shop is equipped to handle a broad range of machining requirements. We work with engineers, buyers, and project managers to deliver CNC parts that meet your exact specifications — the first time.

1

3-, 4-, and 5-Axis CNC Milling

Our multi-axis milling capabilities allow us to produce complex geometries and tight-tolerance features in a single setup. 5 axis machining reduces handling, shortens lead times, and improves part accuracy across all materials.

• 3-axis milling for standard prismatic parts and features
• 4-axis milling for parts requiring rotational indexing and contoured profiles
• 5 axis CNC milling for complex, multi-surface components machined in one operation
• Ideal for aerospace-grade tolerances, custom fixtures, and hard-to-reach features

Our 5 axis machining center delivers the flexibility to machine intricate components that would otherwise require multiple setups or specialized tooling — saving you time and reducing the risk of errors.

2-Axis CNC Turning

Our CNC turning center handles cylindrical and contoured parts with precision. We produce shafts, bushings, fittings, and custom turned components to tight tolerances and surface finish requirements.

• Tight bore and OD tolerances for mating assemblies
• Turned CNC parts for oil & gas, industrial, and packaging applications
• Custom threading, grooves, tapers, and profiles on a single setup

3

Reverse Engineering

Have a worn, obsolete, or undocumented part that needs to be replicated? Our reverse engineering service captures every critical dimension from your existing component and produces a fully documented, production-ready replacement.

• Dimensional inspection and measurement of original parts
• CAD model reconstruction using SolidWorks
• Machined replacement parts delivered to match original specifications
• Ideal for legacy equipment, obsolete components, and undocumented assemblies

4

Custom Component Design & Engineering Support

Our engineering team provides design-for-manufacturability (DFM) support using SolidWorks software. Whether you need a first-article part or a design modification to improve machinability, we work with you from print to finished component.

• SolidWorks 3D modeling and drawing creation
• Design reviews to optimize part geometry for CNC machining
• Engineering support for custom component development
• Collaboration with your team from concept through production

5

Prototype, One-Off, and Small to Medium Production Runs

We specialize in prototype CNC machining and cnc prototyping for new product development. If you need a single part to validate a design or a short run to support a product launch, ITSE Inc. has the flexibility and equipment to deliver.

• Single-piece and one-off machined parts with short lead times
• CNC prototyping to support engineering validation and testing
• Small to medium production runs with consistent quality across every piece
• Fast-turn capabilities for time-sensitive prototype CNC machining projects

Frequently Asked Questions (FAQ)

Everything You Need to Know About ITSE CNC Machining

1. What materials can you machine?

We work with a wide range of metals including steel, stainless steel, aluminum, brass, copper, and tool steel. Contact us with your material requirements and we will confirm compatibility and lead time.

2. Do you offer prototype CNC machining for first-article parts?

Yes. CNC prototyping is one of our core services. We regularly produce first-article and engineering validation parts with short lead times. Provide your SolidWorks file or 2D print and we will quote promptly.

3. What is the advantage of 5 axis machining over 3-axis?

5 axis CNC allows the tool to approach the part from virtually any angle in a single setup. This improves accuracy, reduces setup time, and makes it possible to machine complex features that would require multiple operations on a 3-axis machine.

4. Can you reverse engineer a part if I have no drawings?

Yes. Bring us your physical part and we will measure, model it in SolidWorks, and produce a machined replacement to match. This is common for obsolete components, legacy machinery, and undocumented assemblies.

5. What production quantities do you support?

We work best on prototype, one-off, and small to medium production runs. If you need a single part or a batch of a few hundred pieces, we are the right CNC shop for your project.

5. How do I request a quote for CNC parts?

Send us your SolidWorks file or 2D drawing, specify your material and quantity, and our team will respond with a quote and lead time estimate. Use our contact form or reach us directly at the details below.
