Complex CNC Milled Parts, Engineered for Production

TC Precision manufactures custom CNC milled parts for prototypes, low-volume builds, and production programs.

Our engineers look beyond the CAD model to determine how the part should be fixtured, machined, finished, and inspected before production begins.

From a simple aluminum bracket to a complex multi-face structural component, we combine machining, secondary processes, and quality control into one coordinated workflow.

CNC Milling Capabilities

From Simple Prismatic Parts to Complex 5-Axis Geometries

We choose the machining strategy according to the geometry, feature depth, tolerances, material, quantity, and accessibility of the part.

Part Requirement	Suitable Process
Plates, brackets & simple blocks	3-Axis CNC Milling
Multiple faces & angled features	4-Axis CNC Milling
Complex multi-face geometry	5-Axis CNC Milling
Prototype & low-volume parts	Flexible CNC Milling
Deep pockets & difficult features	Optimized Multi-Axis Milling
Tight flatness & parallelism	Milling + Surface Grinding
Deep small holes	Milling + Gun Drilling
Wire-cut profiles & internal features	Milling + WEDM
Complex internal cavities	Milling + EDM

Why TC Precision for CNC Milling?

Before production, we consider:

Tool accessibility

Workholding

Datum structure

Pocket depth

Wall thickness

Internal corners

Hole depth

Feature orientation

Tolerance relationships

Surface finish

Number of setups

We Plan the Machining Around the Geometry

The goal is to find the simplest stable process that can reliably produce the required geometry.

From First Prototype to Repeat Production

The same component may require a different manufacturing strategy as volume increases.

Prototype Milling

For design verification, fit testing, and functional validation.

Low-Volume Builds

For pilot production, specialized equipment, and early product launches.

Production Milling

For repeat orders where process stability, fixture efficiency, and cycle time become increasingly important.

We can adjust the machining approach as your production requirements evolve.

When Milling Isn't Enough

Some Features Are Beyond the Practical Limits of Milling

CNC milling has inherent limits.

Tool diameter

Corner radius

Tool length-to-diameter ratio

Machine travel

Tool interference

Workpiece accessibility can make certain features difficult—or impossible

To produce accurately with milling alone

Typical problem features include

Instead of forcing the milling cutter to do everything, we introduce the appropriate secondary process.

Sharp internal corners

Deep, small-diameter holes

Extremely small internal radii

Deep narrow slots

Intersecting deep holes

Small chamfers on internal walls

Deep cavities with limited tool access

Other Supporting Processes

The objective is not to use more processes. It is to use the right process for each feature.

Depending on the component, we can combine:

CNC Milling

WEDM

EDM

Gun Drilling

Surface Grinding

Finishing

Inspection

Specialized Milling Applications

Deep-Cavity & Narrow-Feature Milling

Deep pockets and narrow cavities create challenges with tool deflection, vibration, chip evacuation, and tool reach.

We evaluate the depth-to-width ratio, tool accessibility, workholding, and machining sequence before production.

Thin-Wall CNC Milling

Thin sections can distort under clamping forces or cutting loads.

We consider fixture design, machining sequence, stock allowance, cutting strategy, and finishing passes to control deformation.

Complex 3D & Multi-Face Machining

For components with multiple angled surfaces or difficult-to-access features, multi-axis machining can reduce setups and improve positional relationships between features.

Industries We Serve

Industrial Automation

Robot frames, machine bases, mounting plates, actuator housings, tooling components, and automation fixtures.

Semiconductor Equipment

Equipment frames, wafer-handling components, precision plates, vacuum-related structures, and tooling components.

Electronics & Electrical

Heat sinks, electronic housings, connector components, mounting structures, and thermal-management parts.

Optics & Photonics

Optical mounts, instrument housings, alignment components, sensor brackets, and precision positioning structures.

Robotics

Robot frames, end-effector components, joint housings, mounting brackets, structural arms, and precision fixtures.

Aerospace & UAV

Lightweight structural components, brackets, housings, frames, and complex aluminum or titanium parts.

Quality Assurance

Every Critical Feature Has a Verification Method

For CNC milled components, quality is not limited to overall dimensions.

We pay particular attention to:

Position accuracy

Flatness

Parallelism

Perpendicularity

Profile accuracy

Hole location

Critical dimensions

Surface finish

Available Quality Documentation

Dimensional Inspection Reports

CMM Reports

Material Certificates

From CAD Model to Finished Component

One Workflow From Engineering to Delivery

CAD & Drawing Review

We examine geometry, tolerances, datums, and critical features.

Manufacturing Strategy

We determine the suitable combination of milling, EDM, WEDM, grinding, drilling, and finishing.

Workholding & Programming

The part is planned around stable positioning, tool access, and feature relationships.

CNC Machining

The component is produced according to the approved process.

Secondary Processes & Inspection

Special features are completed through the appropriate supporting processes and verified against requirements.

Packaging & Delivery

Finished parts are protected, documented, and prepared for shipment.

More Than a CNC Milling Supplier

We Solve the Manufacturing Problems Behind the Geometry.

A CNC mill can remove material.

The real challenge is deciding how to reach every feature, maintain the relationships between surfaces, control deformation, and complete the features that milling cannot handle alone.

That's where engineering makes the difference.

Engineering → Manufacturing → Quality → Delivery

TC Precision doesn't just machine your parts.
We help you manufacture them better.
