|
" M22  " series pulley grooving insert
is a pulley V-grooves cutting insert with 2 teeth each on its 2 ends.
It is a special design and application, and especially using for grooving deeper position of pulleys
and avoid the machining interference.
You will find more 2 teeth inserts, such as " L22  " and " VT23  "
in our pulley grooving insert family.

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 belt pulleys.
• 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.

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 → Packaging → Warehousing
