产品介绍
The VCGT insert is specially designed for aluminium alloy lathe machining, with a dedicated chipbreaker, which not only eliminates the problem of chip entanglement that occurs during aluminium alloy finishing, but also provides an excellent surface finish.
Key Features
- 形状： VCCT inserts feature an 80° rhombic (diamond) shape, giving them four cutting edges which provides cost-effectiveness.
- 正前角： The cutting face slopes slightly forward from the cutting edge. This often produces a smoother cut with less cutting force, suitable for specific material types.
- 间隙角： Typically around 7° to help prevent rubbing against the workpiece.
- Sharp Cutting Edge: The acute corner radius promotes better surface finishes, especially for finishing operations.
- 断屑槽： VCGT inserts may have chipbreakers on one or both sides to influence chip formation and control.
- 涂料： Often coated with materials like TiN, AlTiN, etc., to improve wear resistance and tool life.
VCGT insert Specification
Understanding the VCGT Code
The letters and numbers in the VCGT designation tell you about the insert:
- 五： 80° rhombic shape
- C： 7° clearance angle
- G： Indicates the specific hole and chipbreaker design (varies by manufacturer)
- 电话： Indicates tolerance class (precision of size)
- 数字：
- Typically, the first two numbers represent the inscribed circle (size of the diamond) 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）。
