VNMG Carbide Inserts For Stainless Steel

VNMG Turning Inserts

35° Rhombic Insert

MP3025 - ISO P20 - P30 Coated cermet grade with improved wear resistance and significantly increased fracture resistance. For use with or without coolant and on interrupted cuts when finish machining steels, stainless steels and cast irons.

Chipbreaker

FH - Finish cutting. First recommendation for finishing carbon steel, alloy steel and stainless steel. Double sided chip breaker. Stable chip control even at small depths of cut.
Depth of cut: up to 1mm
Feed rate: 0.08 to 0.2mm

LM - Light cutting. Excellent burr control. Reduces the incidence of burrs drastically because the sharpness properties and cutting-edge strength are optimized with different rake angles.
Depth of cut: 0.7 - 2.0
Feed rate: 0.10 - 0.40

LP - Light cutting. Butterfly protrusions are optimized for different cutting conditions. Chips curl upwards and reduce cutting resistance, resulting in improved surface finishes. The breaker protrusion is highly resistant to wear even during high-speed machining, delivering stable chip breaking for long periods of time. Excels in copy machining: uses a sharp edge geometry that delivers excellent chip breaking when copy machining and during reverse direction face machining.
Depth of cut: 0.3 - 2.0
Feed rate: 0.10 - 0.40

GM - Sub breaker of the main LM and MM chipbreaker. Excellent notch resistance for light to medium cutting.
Depth of cut: 1.0 - 3.5
Feed rate: 0.10 - 0.35

MA - For medium cutting of carbon and alloy steels. Double sided chip breaker with positive land which provides a sharp cutting action.
Depth of cut: 0.08 to 4mm
Feed rate: 0.2 to 0.5mm

MM - Medium cutting. Excellent resistance to plastic deformation of insert corner as a result of obtaining the optimum land geometry by simulation analysis technology.
Depth of cut: 1.5 - 3.5
Feed rate: 0.15 - 0.30

MP - Medium cutting. Suits a broad range of copy turning conditions, eliminating the need for multiple insert types. Ideal for small cuts: the inner side of the butterfly protrusion has a steep gradient to improve chip breaking performance on small cuts.
Depth of cut: 0.3 - 4.0
Feed rate: 0.16 - 0.50

MS - For medium cutting for difficult to machine materials. Excellent for Nickel base alloys, titanium and stainless steels.
Depth of cut: 0.40- 1.8
Feed rate: 0.08 - 0.20

VNMG inserts are carbide inserts that are commonly used in turning applications. The ISO code "VNMG" specifies the insert's shape, size, and geometry. Here are some advantages of using VNMG inserts:

1.Versatility:

● VNMG inserts are versatile and can be used for a variety of turning applications, including roughing, finishing, and intermediate machining. This versatility makes them suitable for a wide range of materials and cutting conditions.

2. Insert Geometry:

● The VNMG geometry is designed to provide a good balance between cutting forces, chip control, and surface finish. The insert typically has a positive rake angle, which aids in reducing cutting forces and promoting efficient chip evacuation.

3.Chip Control:

● VNMG inserts are equipped with chipbreakers that help control chip formation and evacuation. Efficient chip control is crucial for preventing chip-related issues, improving surface finish, and extending tool life.

4.Insert Size Options:

● VNMG inserts come in various sizes, allowing for flexibility in tool selection based on the specific requirements of the machining operation.

5.Material Compatibility:

● These inserts are suitable for a wide range of materials, including both ferrous and non-ferrous metals. The choice of insert grade can be tailored to the specific material being machined, ensuring optimal performance.

6.Cost-Effective:

● Carbide inserts, in general, are known for their cost-effectiveness. They provide a replaceable cutting edge, allowing for reduced tooling costs compared to solid carbide tools where the entire tool needs replacement.

7. High-Speed Machining:

● VNMG inserts are designed to withstand high cutting speeds, making them suitable for applications that require high-speed machining. ● The combination of carbide material and insert geometry contributes to effective heat dissipation.

8. Consistency:

● Carbide inserts, including VNMG, offer consistency in terms of cutting performance. The predictable tool life and performance make them a reliable choice in various machining scenarios.

9.Application Range:

● VNMG inserts can be used for both external and internal turning operations, making them applicable to a wide range of workpieces and part geometries.

10.Easy Replacement:

● When the cutting edge becomes dull or worn, the insert can be easily replaced, reducing downtime and increasing the efficiency of machining processes.

● It's important to note that the specific advantages of VNMG inserts can vary based on factors such as the insert grade, coating, and the machining conditions. Proper selection of these parameters is crucial to optimizing the performance of VNMG inserts for specific applications.
