R3 Scraper Inserts for CNC Woodworking Machines
R3 scraper inserts are radius (R3) carbide or HSS (High-Speed Steel) cutting inserts used in CNC woodworking machines, particularly for:
-
Edge banding – Smoothing edges after applying laminate or veneer.
-
Surface finishing – Removing excess glue, material burrs, or rough spots.
-
Radius profiling – Creating a precise 3mm radius (R3) edge on wood or composite materials.
Specifications & Features:
-
Material: Typically carbide (Tungsten or Cermet) for long tool life, or HSS for softer applications.
-
Shape: Rectangular or curved, depending on the CNC tool holder design.
-
Coating: Some inserts have a TiN (Titanium Nitride) or TiCN coating for added durability.
-
Compatibility: Used in CNC edge banding machines, trimming stations, or post-processing units from brands like Homag, Biesse, SCM, or IMA.
