VNMG160404-MA steel turning inserts
When turning steel parts, choosing the right blade not only affects the cutting effect, but also has a direct impact on cost and processing efficiency.
Especially for those workpieces with high precision requirements such as slender shafts, stepped parts, chamfered inner holes, etc., ordinary blades are often unable to meet the requirements.
At this time, VNMG160404-MA stands out.
This is a blade model launched by Puwei Cemented Carbide specifically for steel finishing, with a sharp tip, stable cutting performance and excellent cost performance.
What type of Insert is VNMG160404-MA?
Let’s first break down the meaning of this model:
V: Diamond blade (80° sharp angle), suitable for chamfering and processing small parts
N: 0° back angle, negative front angle design, strong rigidity
M: Medium precision, strong installation adaptability
G: With center hole, double-sided
160404: represents side length 16mm, thickness 4.76mm, blade tip radius 0.4mm
MA: Puwei special groove type for finishing steel parts, light cutting and stable chip removal
Three major advantages of VNMG160404-MA in processing steel parts:
1. Sharp tip, suitable for high-precision cutting
The diamond design of VNMG makes the tip very sharp, suitable for processing chamfers, thin shafts, thread guide grooves and other fine parts. Compared with conventional TNMG or CNMG models, VNMG is more capable of detailed processing tasks, especially in the field of automated precision turning.
2. MA groove type has smooth chip breaking and more stable processing
PUWEI MA groove type is optimized for the characteristics of steel parts, which can achieve good chip breaking effect at medium and low feed rates. It is particularly suitable for stable chip removal during continuous processing, reducing chip entanglement problems and improving the surface finish of workpieces.
3. PUWEI quality, wide adaptability and fast delivery
PUWEI cemented carbide not only provides standard blades, but also optimizes and customizes groove type, material and coating according to actual needs of customers. It is suitable for:
Various types of steel parts (such as 45# steel, 40Cr, quenched and tempered steel, etc.)
Ordinary lathes, CNC lathes, automatic Swiss machines
Face turning, chamfering, internal and external circle processing, etc.
Comparison of VNMG160404 and other blade models
| model | Applicable scenarios | Tip Features | Processing characteristics |
| VNMG160404-MA | Fine turning, thin shaft, chamfering | Sharp angles, sharp | High finish, good chip removal, high precision |
| TNMG160404-PM | External rough machining | Blunt tip | Good stability, suitable for large cutting depth |
| CNMG120404-MM | Medium coarse and fine mixed processing | Medium tip strength | Strong versatility and high cost performance |
