SCM Nesting. The clever solution.
At their International exhibition in May 2002, SCM released an ideal solution for "nested based" manufacturing.
Why ideal? Because it’s based on a Router, not a "machining center". And it eliminates the problem of machining waste that remains after "nest" machining. (This waste is held on the table by the powerful vacuum hold-down required by nesting.)
How does it work? It’s based on SCM’s new RECORD 132 flat bed Router with aluminium matrix table. This is a true Router – where the Routing spindle is the core work unit, unlike machining centers where a drilling unit is the core work unit – and routers are "bolt on" additional units.
This gives true heavy routing performance and a better finish at higher feed rates.
The second key is eliminating the waste problem by automatic cleaning and recycling of the "sacrifice" sheets.
This is achieved as follows:
-
The worksheet is loaded onto a sacrifice sheet, already waiting, on a roller table at the right side of the router. Work-sheet loading is done by a vacuum lifter or scissor lift
-
This "nest" is then rolled up to a set of stops
-
When the previous "nest" is complete the router travels to the right and a clamp secures the new "nest" and pulls it onto the worktable. This is assisted by the vacuum pump reversing the airflow, creating a cushion of air, much like a beamsaw air table
-
As this new "nest" is positioned it pushes the completed "nest" onto a sorting table at the left of the router. The pump reverses, creating the vacuum, securing the worksheet and the new "nest" begins
-
While the new nest is being machined the operator unloads the finished components. (Innovative SCM software makes identifying finished components easy for labelling or sorting.) The sacrifice sheet, with all the waste on it, is left where it is - then automatically driven to the rear and tipped on its edge. The waste falls to a conveyor mat and the sacrifice sheet is conveyed along the rear of the router (passing through cleaning brushes) returned to horizontal, and driven forward onto the in feed table - where it’s now ready to have a new work piece loaded and the cycle to begin again
This is a ‘one man’ operation, with a high level of automation - yet compact and affordable.
SCM’s new Nesting software, Door Library software and ASPAN 7 advanced CAD/CAM software controls everything. If you prefer, you can use 3rd party nesting software.
