Board material - Aluminum Composite Panels (ACP)

Modified on Wed, 22 May 2024 at 05:12 PM

Summa Routing systems with universal bits can route aluminum-covered foam board, however, the wear is high.  (Specialized bit stores have specific bits for aluminum)

Some brands offer boards with a different aluminum cover sheet thickness, which impacts the lifetime of the bit.

Bits that have been used for routing aluminum should not be used on other materials.


Settings:


Standard Router: 


< 4 mm thick:  

  • 4 mm Summa bit [#500-9852]
  • 1 pass
  • 80 mm/sec  
  • 25k rpm
  • Counterclockwise


> 4 mm thick:

  • 4 mm Summa bit [#500-9852]
  • Multipass (see further) 
  • 80 mm/sec
  • 25k rpm
  • Counterclockwise


HF Router:


< 4 mm thick:  

  • 6 mm Summa bit [#500-9857]
  • 1 pass
  • 120 mm/sec
  • 35k rpm
  • Counterclockwise

< 6 mm thick: 

  • 6 mm Summa bit [#500-9857]
  • 1 pass
  • 100 mm/sec
  • 35k rpm
  • Counterclockwise


> 6 mm thick: 

  • 6 mm Summa bit [#500-9857]
  • Multipass (see further)  
  • 100 mm/sec
  • 35k rpm
  • Counterclockwise


  • Higher speeds are possible but affect the quality of the edge.
  • If the speed is set too low, the foam will melt.
  • The quality of an edge is best if the material is routed in one pass; however, this may leave a lot of debris on the table.
  • When routing in two passes, make sure the first pass is in the bottom aluminum sheet, if not, the foam may melt.
  • A cleaning pass is discouraged because the small offset may result in cracking of the lacquer on the aluminum sheets.
