Portaplaquitas VBMT

A VBMT Insert Holder is a versatile turning tool holder specifically designed to securely clamp VBMT style indexable cutting inserts. The ISO designation “VBMT” indicates a V-shaped insert with a 35-degree nose angle, a positive rake angle, a clearance angle, and a central mounting hole. A key feature of VBMT inserts is that they typically offer six cutting edges (three on each side), making them a highly economical choice for various turning operations, including finishing, semi-finishing, and light roughing on a range of materials like steel, stainless steel, aluminum, and non-ferrous metals.

The primary function of a VBMT Insert Holder is to provide a stable and precisely oriented platform for the VBMT insert. This ensures accurate material removal, excellent surface finishes, and good chip control. The holder features a precision-machined pocket that conforms to the specific shape and dimensions of the VBMT insert, allowing for secure and repeatable clamping, typically achieved with a screw or lever mechanism. This robust clamping prevents insert movement and vibration during machining, which is crucial for achieving high-quality results, especially in finishing passes and when creating intricate contours.

VBMT inserts are favored for their ability to produce fine finishes and their cost-effectiveness due to the multiple cutting edges. The positive rake angle helps to reduce cutting forces and heat generation. The corresponding VBMT Insert Holders are designed for ease of use, enabling quick and straightforward insert changes, thus minimizing machine downtime. Available in various shank sizes and configurations to suit different machine tool types and application needs, VBMT Insert Tool Holders are a valuable asset in precision machining environments where good surface finish and economical tooling are desired.
