CNC Milling Based on Your Drawings

Most of our CNC milling projects start with a customer drawing.
You can send us a 2D engineering drawing, 3D CAD model, or both. Our engineers review the design before production rather than simply putting the file into a machining program.
We check the details that can affect the final part and the manufacturing cost, including:
✪Material and material grade
✪Critical dimensions and tolerances
✪Hole sizes and positions
✪Threads and tapped features
✪Machining access
✪Thin walls and deep pockets
✪Surface-finish requirements
✪Special inspection requirements
If something in the drawing could make the part difficult or unnecessarily expensive to manufacture, we can discuss it with you before machining begins.
This drawing-review stage is particularly useful for prototypes and new designs, where a small change to the geometry can sometimes reduce machining time or make inspection easier.

CNC Milling From Prototype to Production

CNC milling works well when you need to move from an early prototype to repeat production without completely changing the manufacturing method.

One-Off and Prototype Parts

For product development, you may only need one or a few parts for testing.
We can manufacture prototypes for:
Fit and assembly checks
Functional testing
Design verification
Engineering evaluation
Pre-production testing
There is no minimum order quantity, so you can start with a single CNC milled part.

Small-Batch Production

Once the design has been validated, small-batch production can be used for initial market testing, equipment builds, or ongoing low-volume requirements.
The machining process can be documented and repeated for subsequent orders, helping maintain consistency between batches.

Repeat and Production Orders

For recurring orders, production planning becomes more important than simply making the first part.
We focus on stable machining processes, repeatable inspection, material availability, and consistent finishing so that later batches continue to match the approved part.
Lead time depends on the material, geometry, quantity, finishing, and inspection requirements. Fast turnaround can be arranged for suitable parts after drawing review.

What Parts Can We CNC Mill?

CNC milling is suitable for a wide range of custom mechanical components.
Typical parts we manufacture include:
✪Mounting plates

✪Brackets
✪Housings
✪Covers
✪Fixtures and jigs
✪Mechanical blocks
✪Flanges
✪Structural components
✪Machine components
✪Optical and electronic mounting parts
✪Custom enclosures
✪Prototype components
The machining approach depends on the geometry.
Simple parts may only require standard 3-axis milling, while components with features on several faces or more complex surfaces may require additional setups or multi-axis machining.
Rather than applying the same process to every part, we select the machining approach according to the drawing and the features that need to be produced.

CNC Milling Materials

We machine a broad range of engineering materials. The right choice depends on strength, weight, corrosion resistance, thermal requirements, wear, operating environment, and cost.

Aluminum

Aluminum is one of the most commonly machined materials for CNC milling. It is relatively lightweight, easy to machine, and available in a range of grades.
It is commonly used for:
Housings
Brackets
Mounting plates
Fixtures
Structural components
Anodizing can be added when additional surface protection, appearance, or wear resistance is required.

Stainless steel

Stainless steel is suitable when corrosion resistance and mechanical strength are important.
304 stainless steel is a common general-purpose option, while 316 may be considered for more demanding environments.

Carbon steel

Carbon steel is often used for mechanical and structural components where strength and cost are important considerations.
Additional surface treatment may be used when improved corrosion protection is required.

Titanium

Titanium is selected for applications where high strength-to-weight ratio and corrosion resistance justify its higher material and machining cost.

Brass and Copper

Brass and copper are useful where electrical conductivity, thermal conductivity, or specific mechanical properties are required.

Engineering Plastics

Engineering plastics can be machined when low weight, electrical insulation, chemical resistance, or reduced friction is important.
If the material is not specified in your drawing, we can discuss suitable options based on the intended application.

Surface Finishing for CNC Milled Parts

Machining does not always produce the final surface required for a component.
Depending on the material and application, we can arrange additional finishing processes such as:
✪Anodizing
✪Powder coating
✪Sandblasting
✪Polishing
✪Black oxide
✪Passivation
✪Plating
The finish should be selected according to what the part needs to do.
For example, anodizing may be appropriate for aluminum parts that require additional surface protection, while passivation is commonly used for stainless steel to improve corrosion resistance.
If a surface finish is specified on the drawing, we manufacture and inspect the part according to that requirement.

How We Handle a CNC Milling Project

1. Send Your CAD Files

Send your 2D drawing, 3D model, or both.
Common formats include:
STEP / STP,IGES / IGS,X_T,SLDPRT,DWG,DXF,PDF

2. Drawing and Manufacturability Review

Our engineers review the design and identify the dimensions, materials, tolerances, finishes, and other requirements that affect manufacturing.

3. Quotation

We calculate the machining and finishing requirements based on the actual part rather than using a generic price.
For complete project information, quotations are typically provided within 24 working hours.

4. CNC Programming and Machining

After order confirmation, the drawing is converted into machining programs.
The appropriate tools, workholding method, machining sequence, and cutting conditions are selected according to the material and geometry.

5. Inspection

Critical dimensions are checked during and after production.
Inspection can include dimensional measurement, thread inspection, visual inspection, surface-finish checks, and CMM inspection when required.

6. Finishing, Packaging and Delivery

After machining and inspection, parts receive the specified surface treatment, are cleaned and packaged, and then shipped using the agreed delivery method.

Where CNC Milling Accuracy Matters

Not every dimension on a CNC part needs the same level of control.
The critical dimensions are usually the ones that affect:
✪Assembly
✪Alignment
✪Movement
✪Sealing
✪Interchangeability
✪Functional performance
For these features, the drawing may specify tighter dimensional or geometric tolerances.
We manufacture according to the tolerances specified on your drawing rather than applying unnecessarily tight tolerances to every feature.
This approach can help balance part performance and manufacturing cost.

Quality Control for CNC Milled Parts

A CNC machine can produce a dimension accurately, but consistent production also depends on how the part is inspected and controlled.
Our quality process covers the manufacturing stages from incoming material through final inspection.
Depending on the project, we can check:
✪Critical dimensions
✪Hole diameter and position
✪Thread dimensions
✪Flatness
✪Parallelism
✪Perpendicularity
✪Surface finish
✪Overall appearance
✪Final part conformity
Inspection reports can be supplied when required.
Our CNC milling production operates under an ISO 9001 quality management system, with inspection requirements based on customer drawings and project specifications.

What Determines the Cost of CNC Milling?

Two parts with similar dimensions can have very different machining costs. The main factors include:

Material

Titanium, stainless steel, aluminum, plastics, and other materials have different raw material and machining costs.

Part Geometry

Deep pockets, thin walls, complex surfaces, internal features, and difficult tool access can increase machining time.

Tolerances

Tight tolerances may require additional machining control, inspection, and sometimes additional operations.

Quantity

A prototype carries setup and programming costs on a single part, while larger quantities allow these costs to be spread across more components.

Surface Treatment

Anodizing, plating, passivation, powder coating, and other finishes add processing time and cost.

Inspection

CMM inspection, dimensional reports, material certificates, and other documentation may be required for more demanding projects.

For an accurate quotation, the best approach is to send the drawing, material, quantity, and finishing requirements together.
