Board material - Aluminium Composite Panels (ACP)

• Summa Routing systems with universal bits can route aluminum-covered foam board, however, the wear is rather 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: 

• up to 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:

• up to 4 mm thick:  
  • 6 mm Summa bit [#500-9857]
  • 1 pass
  • 120 mm/sec
  • 35k rpm
  • Counterclockwise
• up to 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 the edge is better 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
