TNGN CBN Inserts

Features

Introduction

TNGN series cubic boron nitride inserts have a stable regular triangle shape with superior cutting performance and are suitable for high-speed dry cutting. They are widely used in gray cast iron, ductile cast iron, wear-resistant alloy cast iron and various cast steels and hardened steel Processing, can withstand large cutting depth, large cutting, can adapt to intermittent cutting, cutting depth to control the inserts radius is preferably within two thirds.

Advantages

The finish of finishing turning reaches Ra0.4 to achieve grinding instead of grinding and improve efficiency

Can process Rockwell hardness range HRC45-90

Large cutting depth(<1/3 length of insert)

Can withstand high temperature of 1400 degree

Unlimited regrind, high blade utilization

Precautions

1. Should be used having a sufficient power and rigidity of the machine tool system;

2. Try to use a larger radius of the tool tip arc to ensure the maximum strength of the tool;

3. Perform negative chamfering on CBN turning inserts to avoid chipping during chip breaking;

4. Do not use cutting fluid during high-speed intermittent cutting.
