製品紹介

The VBGT insert is specially designed for aluminum 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.

VBGTインサートの主な特徴

80° Rhombic Shape: Provides four cutting edges and strength for general purpose turning.
ポジティブ・レーキ・アングル： This can offer a slightly smoother cut and lower cutting forces compared to negative rake inserts.
Chipbreaker Options: VBGT inserts feature various chipbreaker designs for influencing chip flow during specific operations.
コーティング： Often coated with TiN, TiCN, AlTiN, etc., for improved wear resistance.

VBGT insert Specification

Here’s a breakdown of VBGT insert specifications, including the code meaning and important features:

VBGT Designation

V: 80° rhombic shape. This offers stability and strength for varied turning operations.
B: 5° relief angle (clearance angle).
G: Chipbreaker type and hole design (varies between manufacturers).
T: Indicates a tolerance class for precision of inscribed circle and thickness.

Common VBGT Dimensions

VBGT inserts, like many others, have numbers that determine their size:

VBGT 110X0X:
- Inscribed Circle (IC): 0.125″ (1/8″)
- Thickness: 0.094″ (3/32″)
- X represents the nose radius (e.g., 1 = 1/64″, 0 = sharper corner)
VBGT 160X0X:
- Inscribed Circle (IC): 0.625″ (5/8″)
- Thickness: 0.125″ (1/8″)
- X represents the nose radius
