≡≡ Insert Introductions ≡≡

' Q ' series pulley grooving insert is a pulley V-grooves cutting insert
with (4) FOUR cutting edges on 1 end.

Researching and developed by SCT, the brand new automotive belt pulley grooving inserts are receiving good reputation among our worldwide customers: 
•  These inserts are made by solid carbide materials.
•  Inserts are especially designed and produced for cutting V grooves in automobile belt pulleys.
•  Support to ‘make ONE-TIME cutting’ for precise machining of V grooves in pulleys.
•  Greatly improve belt pulleys’ machining accuracy and surface roughness.
•  Largely help reduce time in changing of different inserts.
•  Exponentially shorten the machining time on pulleys have multiple V grooves.
•  Make large progress of working efficiency and on product quality.

 ≡≡  Workpiece Materials ≡≡

  # (B00)  →  Machining workpiece made in aluminum alloy or bronze alloy.
# (B09)  →  Machining workpiece made in ductile cast iron.
  # (B20)  →  Machining workpiece made in free cutting steel.
# (H10)  →  Machining workpiece made in stainless steel.                                              

≡≡  Tool-holder ≡≡

Pairing with SCT 's pulley grooving inserts, our tool-holders are made by 42CrMo. SCT suggest all our custoemr to use our tool-holder to pair our inserts. That not only help promote grooving efficiency and grooving precision, but also help extend inserts' working life. Below is the production process:

42CrMo Forging → Tempering → Rough Processing → Quenching → Fine Machining  → Surface Blackening. 

When pairing pulley grooving insert with its tool-holder, please ask SCT sales team for suggestions. 

    ≡≡  Custom-Made Inserts ≡≡

SCT are providing our worldwide customers with insert-copying, new insert-engineering services. Making satisfied inserts and their tool-holders on our customer's request are our pursuit !
