产品介绍
VNMG Insert is made of high quality alloy metal with advanced technology.
The surface is treated with special coating to extend the using life.
The unique V shape design with negative angles of the VNMG Insert guarantees efficient machining and high stability.
The combination of different chip breakers and grades will help it to deal with different working condition and multiple operations.
In addition, it has the advantages of high hardness, high efficiency, high accuracy, corrosion resistance, long service life, smooth appearance as well as high quality.
Key Features
- 形状： VNMG inserts are triangular with a 35° included angle, providing a good balance between strength and sharpness. This shape offers three usable cutting edges.
- Negative Rake Angle: The cutting face slopes backward from the cutting edge, providing a strong, durable edge well-suited for tougher materials and interrupted cuts.
- 间隙角： Typically 7° to help prevent rubbing against the workpiece.
- 断屑槽： VNMG inserts often feature chipbreaker geometries to control chip formation and flow during machining, tailored to specific applications.
- 涂料： Often coated with materials like TiN, AlTiN, and others to improve wear resistance and tool life.
VNMG insert Specification
Understanding the VNMG Code
The letters and numbers in the VNMG designation signify important details:
- 五： 35° rhombic (diamond) shape
- N: Negative rake angle
- 中号： 公差等级（表示尺寸精度）
- G： Indicates hole type and chipbreaker design (varies by manufacturer)
- 数字：
- Usually, the first two numbers represent the inscribed circle (size of the triangle) in sixteenths of an inch (or directly in millimeters for ISO codes).
- 第三个数字代表厚度（以十六分之一英寸为单位）。
- 最后一个数字通常表示刀尖半径（越小意味着越锋利）。
