Improves Clean Up on Poorly Welded PVC Joints
A
new system for the automatic cleaning of welded joints that are not
always a perfect square has been invented, designed and patented by
Kombimatec here in the UK.
Automatic PVC weld cleaners are an essential piece of machinery for
any fabricator to produce windows & doors competitively. The very
best cleaning results are achieved when accurate square welds are consistently
produced.
Due
to tolerances building during the fabrication process it is impossible
to get 100% accuracy. For example there is always a tolerance on sawing
to start with. Welded joints, in practice, can often out of square.
Either too open, more than 90 degrees or too closed, less than 90 degrees.
This manifests itself by grooving offline that can be unsightly or missing/half
cleaning a bevel or decorative moulding resulting it being necessary
to finish the cleaning by hand.
Kombimatec has patented a new system for its CNC cleaners to assist
the operator in two beneficial ways and help overcome these manufacturing
problems.
The first benefit is the assistance it provides the operator for inserting
the frame down the centre of the weld. This helps the prevent the cleaning
tools deviating from the correct path.
The second benefit comes from the machine recalculating totally automatically
the new start position of the tools which inevitably will need to differ
if the joint is not 90 degrees. 90 degrees being the standard CNC cleaning
program. The result being a more thorough and consistent cleaning of
the bevel, ovolo or other decorative shape.
As a result this new invention further deskills the operation and reduces
the waste associated with reworking, or in some cases, the scrapping
and remaking of the frame.
This system is being offered on all new CNC cleaners manufactured by
Kombimatec and can be retrofitted to existing owners of Kombimatec CNC
cleaners built since 1999.
