Korloy CCMT Turning Insert - CCMT-HMP, CCET-CCET-CCET-KM

What is a Korloy CCMT Turning Insert? The CCMT designation stands for Corner, Cutting, Multiple, Triangle, referring to the triangular shape of the insert with a 90° cutting corner. These inserts are designed for versatility and can be used for a variety of turning operations including roughing, semi-finishing, and finishing. Korloy’s CCMT inserts are often coated with advanced materials to enhance performance and tool life.

Types of Korloy CCMT Turning Inserts:

1. CCMT-HMP:

   • HMP stands for High Material Removal and Performance. These inserts are designed to handle heavy cutting loads and high material removal rates, making them ideal for roughing and semi-finishing operations.
   • Features: These inserts are made from high-quality carbide materials and are coated with a layer of PVD (Physical Vapor Deposition) coating for improved hardness and wear resistance. The HMP design ensures high performance and durability, even in tough machining conditions.
   • Applications: The CCMT-HMP inserts are ideal for high-speed, high-volume turning operations where the need for fast material removal and minimal tool wear is critical. They are particularly suited for machining ferrous materials such as carbon steel, alloy steel, and cast iron.

2. CCET (Cermet-Coated Inserts):

   • Material: The CCET inserts are typically made from cermet, a composite material made of ceramic and metal. These inserts combine the hardness of ceramics with the toughness of metal, making them ideal for finishing operations.
   • Coating: CCET inserts are coated with CVD (Chemical Vapor Deposition) coatings that enhance their wear resistance, making them suitable for high-precision work on steel and other difficult-to-machine materials.
   • Applications: These inserts are ideal for high-precision finishing operations where a high surface quality and tight tolerances are essential. CCET inserts are particularly effective in machining stainless steel, hardened steel, and other hard alloys, where their durability and sharp cutting edges provide superior finishes.

3. CCET-KM (Korloy Modified):

   • Modified Design: The CCET-KM version is a modified variant of the standard CCET insert, designed specifically for high-performance machining of materials requiring both toughness and sharp cutting edges. This modification improves the insert's chip control, reduces cutting forces, and ensures longer tool life in challenging applications.
   • Coating: The inserts are coated with a specially engineered layer that improves wear resistance and heat resistance, allowing the tool to perform well at higher speeds and temperatures.
   • Applications: The CCET-KM inserts are suitable for demanding operations such as heavy-duty turning, high-precision finishing, and machining hard materials. They are highly effective in industries like aerospace and automotive, where precision and durability are critical.
