Artec Engineering Precision Metal Spinners recenly completed the manufacture of some end cap spinning’s that will go onto to be used in the filtration industry.
We have a long association with supplying spun parts to be used in this industry and work with some of the global leaders in this field.
This particular spinning was a repeat order that has is own specific tool to form the spinning to the correct dimension.
How do you get the metal blank to have two parallel returns?
This particular spun part is recessed and has a central locator, which is required to attach onto a separate unit.
To achieve this recess, we first begin by getting a blank lasered, with the required outer diameter dimension and the internal diameter dimensions.
This is often refereed to as a ‘washer blank’ due to it looking like your standard washer.
Having the central cut out, will allow this internal section of metal to be spun inwards.
How to achieve the external parallel
After receiving the washer blank, our expert metal spinner will centralise the material on the turning lathe, so that when pressure is applied, this will create a uniform parallel return.
You can see from the video, that pressure is applied using a hand tool to flatten the material against the tooling.
To achieve the correct dimensional height of the spinning, the operator will remove the excess material until it is level with the tooling and this process is often referred to as ‘skimming’
How to create the central recess
To create the central recess, this requires access to the centre of the material the pressure pad to be remove to allow access to the centre of the spinning.
The spinning is taped to the tooling to keep the spinning secure during the second spinning operation.
You can see in the video, that a hand tool is used to gently apply pressure to the internal material to fold the material against the tool to create the recess.
The part is then cleaned and ready to be packaged for dispatch
