At Artec Engineering Precision Metal Spinners, we produce spun parts for a wide range of industries and these can range from a 1 off to 1000s of repeat parts.
To enable us to continue being an industry leader in Metal Spinning, we made significant investments in two new CNC spinning machines to ensure that we could meet the demands of our customers.
Both of our CNC’s were bespoke and produced in Barcelona, Spain by DENN.
DENN CNC Spinning Lathe
The first of our CNCs is our DENN bespoke machine built to our specification and will produce spinning’s up to 1500mm in dia. from all materials up to and including 5mm st/st, 6mm m/st & 7.00mm Alloy.
The machine is designed to use tooling weighing over 1.3 tonne and will produce high and low volume production runs with world class quality finish and dimensional repeatability.
DENN Beading & Flanging Machine RBV-160
The second of our CNCs is our beading and flanging machine RBV-160. This DENN bespoke machine built to our specification and configured to cover a range of parts from 400 dia. up to 1600 dia. from a range of materials including st.st / m/st. and alloy.
The RBV-160 enables us to produce high and low volume production runs with a superior finish and dimensional repeatability.
Why use a CNC machine compared to hand spinning?
When there is a requirement for a high volume of parts to be produced, the CNC can significantly reduce the manufacture time, whilst still maintaining dimensional repeatability and quality.
Using the CNC to manufacture spun parts, allow production to be scaled up but most importantly for the customer this helps to reduce manufacturing cost over time.
How is the part spun on a CNC?
As with hand spinning, the CNC spinning will still require a tool or former to shape the metal blank to the required shape.
For some parts the blank can be spun in one go but for others this requires two stages.
The operator begins the process by loading the blank which is located centrally on the tooling and clamped by the tailstock.
After the blank has been located, the operator will slightly lubricate the blank prior to spinning and will begin the automated spinning process.
Once the programme is engaged, the tooling and blank will begin to rotate at high resolution and a roller tool will engage the material and gradually apply pressure to begin to form the part in small strokes.
Types of parts spun on a CNC
Here are some examples of spun parts produced on a CNC
One spinning operation
Two spinning operation
Due to the shape of the finished part, this particular spinning has to go through an initial draft to create the first form.
This draft spinning is then located back on the CNC and the final draft is completed
