DNGA-ZH CBN Inserts

Features

PCBN braze inserts is integral sintered CBN small knife particles brazed on CNC alloy substrate in high vacuum and high temperature environment. The tip part is integral CBN material with center hole positioning.

Characteristic	Advantages
1.Widely application	Can meet finishing, semi-finishing and roughing.
2.High welding strength	Welding temperature can reach more than 900 degrees,the cutting edge can withstand 750 degrees cutting temperature without falling off.
3.Good chipping resistance	The blade is integrally sintered material.
4.Complete clamping arbo	Replace coated inserts and do not require changing holders.
5.Center hole location	Location hole is designed according to customer’s need.

Applications and Advantages

1. Can meet rough, semi-finish and fine processing;

2, high welding strength, can withstand higher cutting temperatures and cutting forces.

3, suitable for cutting depth <3mm processing conditions, can meet the strong intermittent, weak intermittent and continuous processing environment;

4. Corresponding clamping tool bar can be used to directly replace the coated blade without changing the tool bar.

5. This structure is recommended for hard steel processing.

6, can be regrind, but limited times.
