Turned Part – What is one and where are they used?
A turned part is a key component in many items and products we use in our day to day lives. Generally they start off as a “slug” of material which is placed into a machine called a lathe. The slug is then rotated at a suitable speed in the lathe spindle and is either then turned, drilled or threaded by using the following tools:
- Drill Bit – Used for drilling holes in turned parts.
- Machine tap/Chasing tool – Machine taps are used for producing internal threads where as external threads are chased.
- Turning tool – Used for either facing the slug or turning along longitudinal axis (z axis).
What materials are they made from and why?
Turned components can be manufactured from ferrous, non-ferrous and plastic materials. For a greater understanding see the list of commonly used material below:
- Steel – Generally ideal for machining and offers good strength.
- Stainless Steel – Hard to machine but has great strength and does not rust,
- Aluminium – Easy to machine and offer good weight saving properties due to being light.
- Brass – Excellent machining properties, Looks nice, does not corrode.
- Nylon – Machines well and is fairly hard wearing.
What industries and products use a turned part?
Nearly all mechanical products have a need for turned or machined components. The main industries to use them are as follows:
A turned part can be found in every car that is manufactured across the world. Looking at the leisure industry, nearly every piece of gym equipment contains a turned part because they offer a function.
