Metal Cutting & Guillotining
Welders join metallic materials together using heat and filler material. At TNN Engineering we can weld a variety of materials including:
- Mild Steel
- High Tensile Steel
- Bisalloy wear plate
- Stainless Steel
- Cast Iron
We have numerous machines and processes that we use for welding which include:
- MIG welders, GMAW
- TIG welders, GTAW
- Pulse MIG welders
The predominant and most efficient method of welding is MIG welding. We have the latest Pulse MIG welders which are computer controlled for more consistent welds with less distortion and better penetration.
Sand blasting uses compressed air and blasting media to prepare and clean part surfaces.
Special “sand” and grit is blasted at the surface to remove rust, scale and to provide an even uniform surface which is an ideal preparation for painting or powder coating.
This process is also used for cleaning up surfaces after heat treatment or brazing. It removes soot, excess flux and heat marks.
Sand blasting can also be used for cosmetic purposes. It leaves a dull uniform finish and removes most machining marks.
It is also recommended as a surface preparation for gluing of parts. The blasting process provides a rough textured finish with more surface area which is ideal for most gluing applications.
At TNN, we can process small to medium parts. We can also arrange blasting of large components such as car bodies and truck trays.
Fitting & Assembly
As well as manufacturing your parts, we can also fit and assemble your components to deliver a finished product. Some examples include:
- Fitting of internal or external bearings
- Pressing of plain bearings and bushes
- Installation of grease nipples
- Assembly and installation of bolted connections
- Cir-clips, orings and seals
- Full assembly of rollers including shafts, bearings and clips
- Post assembly painting, labeling and packaging
- Engraving and marking
- Re-configuration of valves and fittings
CNC Machining Centres
We have a range of CNC machining centres to cater for jobs up to 1000mm long. We have 3 axis and 4 axis machines for rotary milling.
We currently have 4 CNC machining centres. Our machines have quick and powerful conversational programming that allows quick setup and changes to programs. This allows us to optimise programs easily even if they are only small runs of parts.
Metal Folding Press Brake
Press brakes are used to accurately press and bend sheet and plate material.
Our press brake has a 100 tonne capacity and can press items up to 3200mm long.
