MGMN300-M Grooving Carbide Inserts Storefront CNC Yellow Coating 20pcs

Description

Product Overview

The MGMN300-M grooving carbide insert series is engineered for high‑performance CNC turning and grooving applications. Each insert is fabricated from solid tungsten carbide, delivering exceptional hardness, toughness, and edge retention. The CVD yellow coating applied to the cutting edge provides superior wear resistance, thermal stability, and a polished finish that minimizes chip adhesion. With a cutting width of 5.5 mm, a length of 21 mm, and a thickness of 3 mm, the inserts are sized to fit standard MGEHR and MGIVR tool holders, offering a corner radius of 0.4 mm and a zero‑degree lead angle for optimal material engagement. The package includes 20 pieces, ensuring sufficient inventory for continuous production runs.

Usage

These inserts excel in machining a wide range of materials, including carbon steel, alloy steel, cast iron, and non‑ferrous metals such as aluminum and copper alloys. The unique groove geometry promotes efficient chip evacuation, reducing the risk of chip re‑cutting and surface finish defects. Operators can employ the MGMN300-M inserts in turning, grooving, and cut‑off operations on CNC lathes, where high spindle speeds and feed rates are required. The inserts are particularly well‑suited for high‑speed machining environments where thermal management and tool longevity are critical. Their compatibility with standard MGEHR and MGIVR holders simplifies tool changeovers, allowing quick adaptation to varying workpiece geometries.

FAQ

What materials can the MGMN300-M inserts machine?

They are suitable for machining steel, cast iron, aluminum, copper alloys, and other non‑ferrous metals, providing reliable performance across a broad material spectrum.

How does the CVD coating improve performance?

The CVD coating creates a hard, heat‑resistant surface that reduces friction, minimizes wear, and helps maintain a consistent cutting edge even at high spindle speeds.

Are the inserts compatible with all CNC lathe models?

They are designed for standard MGEHR and MGIVR grooving‑cut‑off tool holders, which are common on most CNC lathe platforms. Verify holder dimensions for exact fit.

What is the recommended feed and speed range?

Typical feed rates range from 0.05 to 0.2 mm/rev and spindle speeds from 2,000 to 6,000 rpm, depending on material hardness and desired surface finish. Adjust parameters based on specific machining conditions.

How many inserts are included in the package?

Each package contains 20 high‑quality carbide inserts, providing ample supply for medium‑scale production runs.
