SNMA Insert can deal with multiple operations by combining different chip breakers and grades;

Material : Tungsten Carbide;

Specification

SNMA carbide inserts have 4 cutting edges per side. If the insert is negative then it is possible to use a total of 8 corners.

In this case, it makes this style of insert very economical.

It has a cutting edge angle of 90° so it has high cutting edge strength.

Normally, the insert dimension depends on the needs of customers and the space for the cutting tools in the application.

In addition, the Indexable Carbide Insert has gone through various processes such as quenching to improve its performance.

The surface has been treated with a special coating, thus it gains the properties of corrosion resistance and rustproof.

What’s more, it has the properties of good positioning accuracy, high hardness, long service life, wear resistance, corrosion resistance as well as cost effective.

The Indexable Carbide Insert is widely applied in metal turning, milling, cutting and grooving, thread turning, etc.

Understanding the SNMA Insert Code

S: Shape: Square
N: Clearance Angle: Negative
M: Tolerance: Medium tolerance is standard, though other precision tolerances might be available.
A: ブレーカ形式 & 穴の構成。この文字は、特定のブレーカ形状と、インサートに穴があるかどうかを指定します。ブレーカのバリエーションは数多くあり、メーカーごとに異なります。
数字:
- 最初の 2 桁: 内接円 (IC) の直径 (ミリメートル単位)。おおよそのインチ相当値を取得するには、この数値を 25.4 で割ります。
- 次の 2 桁: 厚さ（ミリメートル）。インチに変換するには、25.4 で割ります。
- 下 2 桁: Corner radius in millimeters. To convert to inches, divide by 25.4.
