Design Guidelines

Optimize your designs for manufacturability with our expert guidelines and feedback, ensuring the best results in CNC machining.

Maximize the internal radius.
Internal cuts create a fillet half the tool diameter. To save time, use a radius greater than 1/3 of the machining depth. For efficiency, relieve internal corners and use a consistent radius across all edges, allowing the same tool for process.
Avoid excessive cavity depth, grooves, and holes.
Cavity and groove depth should be 3-4 times the tool diameter. For holes, max depth is 4x the diameter, with a minimum of 1mm. Standard holes reduce costs and improve precision.
Try you best to avoid thin walls
Thin features are prone to vibration, so wall thickness should be at least 0.5-0.8 mm for metal and 1.0-1.5 mm for plastic. For support or taller features, increase wall thickness to reduce vibrations during machining.
No small text
For marking parts with text, electrochemical etching or laser marking is faster and more efficient. If cutting text, use recessed, simple, large fonts with a depth no greater than 0.3mm. otherwise, this will be bad.
Standards for threads
For threads, keep length up to 3 times the hole diameter. For blind holes, add at least 1/2 hole diameter at the root. Consider using inserts, threaded coils, or brass nuts for longer durability, especially in soft materials like aluminum or plastic.

Surface Finishes

We are offering over 20 options of surface finishes to fulfill both your functional and aesthetic requirements.

Brushing

is a surface treatment that grinds the workpiece, creating decorative lines for an attractive finish.

Sand Blast

uses high-speed sand flow to clean and roughen a product's surface.

Polishing

uses abrasives or buffing wheels to smooth surfaces, remove imperfections, and create a reflective finish.

Tumbling

is a surface treatment that rotates materials with abrasive media in a drum or container.

Anodizing

enhances by forming a protective layer that improves corrosion resistance, hardness, and appearance.

Painting

This process improves the tactile feel but may be prone to scratches.

Black Oxide

an oxide film used to improve corrosion resistance, enhance appearance, and reduce light reflection.

Electroplating

is used for functional, decorative, and corrosion-resistant purposes in various industries.

Powder Coating

applies electrostatically, then cures it with heat or UV light for a durable, attractive finish.

Alodine

is a protective conversion coating for aluminum that prevents corrosion and acts as a primer for painting.

Passivation

enhances corrosion resistance by immersing it in an acid to remove contaminants and form a protective layer.

Electroless Plating

is a chemical process that deposits metal onto a substrate without electrical current.

FAQ

To provide clarity on our services, here are answers to frequently asked questions about prototyping and manufacturing.

Choosing the right machining material depends on several factors, including the application, mechanical properties, cost, and manufacturing requirements. Here’s how to make the right choice:

  1. Consider the Application – Determine the material’s required strength, durability, heat resistance, and environmental conditions.
  2. Evaluate Mechanical Properties – Look at hardness, tensile strength, wear resistance, and machinability.
  3. Assess Cost and Availability – Balance performance with budget and material availability.
  4. Check Compatibility with Manufacturing Processes – Ensure the material is suitable for CNC machining, milling, turning, or other processes.
  5. Review Industry Standards and Regulations – Some applications require specific certifications, such as RoHS compliance or FDA approval.

Getting a manufacturing quote typically involves the following steps:

  1. Prepare Your Design Files – Submit 3D CAD models (e.g., STEP, IGES, or STL files) and 2D drawings with specifications.
  2. Specify Materials and Requirements – Choose the desired material, surface finish, tolerances, and any special requests.
  3. Provide Quantity and Lead Time – Indicate the number of parts needed and your preferred turnaround time.
  4. Submit Your Request – Send your details to the manufacturer via their website, email, or an online quoting platform.
  5. Receive and Review the Quote – The manufacturer will assess your request and provide pricing, lead time, and production feasibility.
  6. Confirm and Proceed with Production – Once satisfied with the quote, place your order to start manufacturing.

For quoting, TonZa prefers 3D CAD files in STEP, IGES, X_T, or STL formats.
2D CAD drawings with reference dimensions should be provided in DWG or PDF formats.
All TonZa processes rely on high-quality 3D CAD solid models.
