Machining

What tolerance can you work to?

We can maintain tolerances of 10 microns on most components. ie 0.01 mm
Our general tolerance for machining is 0.3 mm

What are the largest parts that you can machine?

We can turn components upto 500 mm in diameter
Our milling machines can machine parts upto 1200 x 700 x 500 mm

Where is the largest through bore capacity?

We can accommodate up to 90 mm through the spindle bore of our lathes
We can bar feed up to 60mm

Fabrication

What materials can you weld?

We can weld Steel, Stainless Steel and Aluminum

Can you weld bronze?

Yes, we have a welding machine and consumables that can perform bronze welding.
We can weld bronze to bronze or bronze to steel.

Do you do offsite work?

No, we can only weld and fabricate items at our workshop in Carole Park

How long will it take?

Please allow 2-3 weeks for a typical fabrication job to be completed
External operations such as Galvanising and Powder coating can add an extra 1-2 weeks for each process

3D Printing

What materials can you print?

We print mainly in ABS plastic.  The same stuff that Lego is made from.
We can also print PLA.  It is not as strong as ABS, but has less shrinkage.

What CAD file format can be used?

We can work with STL, IGES, STEP or SAT files.

How long will it take?

Most prints can be done overnight.
Larger prints can take a few days to process.

How much will it cost?

Generally, 3D printed parts are about 1/10 of the price of a machined component.

Prototyping

How long will it take to make a prototype?

Depending on the complexity, it normally takes 2-3 weeks.

How can I reduce the cost of my prototype?

The majority of the cost in a prototype is the programming and setup.  The unit cost of the prototypes can be greatly reduced by increasing the quantity to 2 or more parts.
Please provide as much detail about the component as possible. Eg, tolerances and critical features and dimensions.
Consider 3D printing (rapid prototyping) some of the less critical components.

I have used TNN Engineering over a period of 5+ years, and always found them to deliver high quality products, on time and on budget. I have always found Tin and the sales team to be responsive to my needs, answer questions where necessary and follow up with me when further clarity on a drawing or specification is required.TNN Engineering is my go to when I need machining or fabrication for a competitive cost, whilst still meeting my high standards of quality and repeat-ability.

From the initial meeting to discuss my job, to the end when picking up the completed task, the staff at TNN where always friendly, and willing to discuss options and solutions to my engineering problems. At all times the team kept up good communications, and kept me informed as to the progress of my job. The job itself, and quality of workmanship is far superior than others in their field. I could not have asked for a more structurally engineered product. Can't recommend the team at TNN enough, thank you !!

Tin & Le from TNN Engineering are truly masters at what they do. Take one look at the workshop and you know this team has their house in order. Reliable, trustworthy and in it for the long game. If you choose to partner up with them for an engineering or metal fabrication project you won't be sorry.

I have been fortunate enough to have engaged the team at TNN Engineering for multiple projects over the past few years, ranging from machined aluminium and plastic components, through to complete fabricated assemblies. Each project has been completed to a high standard with outstanding professionalism and workmanship. They completed the work in a reliable, timely manner despite the variations in work required for each project. I'd happily engage TNN Engineering again in the future & would highly recommend TNN to anyone seeking machining and general fabrication for their project needs.
