What is Cnmg insert?
This CNMG Insert is suitable for high speed continuous cutting. Features: •Durable. •Superior finish. •Used for CNC turning inserts.
Can HSS cut Inconel?
it is not possible to machine the Inconel 718 with HSS cutting tools. Inconel 718 is a high heat resistance alloy which can maintain its hardness and creep resistance upto 1000 degree Celsius.
Is Inconel machinable?
The machinability index of Inconel 718 is very low in the order of 12, compared to that of low carbon steel (AISI 1018) having a value of 100 (Fig. 2 (a,b)). Inconel 718 was widely given the title/tag of “difficult-to-cut material” since it possesses some indigenous characteristics which hinder its machinability.
What is the cutting speed for Inconel?
20– 25m/min
The recommended cutting speed for machining Inconel 718 using the carbide inserts should be within 20– 25m/min, the feed rate should be 0.15–0.20mm/rev and the depth of cut should be higher than 1.0 mm.

How do I choose carbide inserts?
How to choose correct turning insert
- Select insert geometry based on selected operation, for example finishing.
- Select the largest possible nose angle on the insert for strength and economy.
- Select the insert size depending on the depth of cut
- Select the largest possible nose radius for insert strength.
Why is Inconel so hard to machine?
This is because as the repeated pecks hit the Inconel can cause dislocations in the microstructure of the material. Such dislocations cause the material to become compacted at the microscopic level—making the surface harder.
Why is Inconel expensive?
In other words, Inconel has a high tolerance towards extreme heat and can keep its tensile strength at high temperatures without any change. However, this material is expensive. In addition to tolerating extreme heat, these alloys are oxidation-corrosion resistant.
Is Inconel 625 machinable?
Inconel 625 is a Nickel-based heat resistant superalloy (HRSA) material with a Machinability rating of 17% and Hardness of 29 HRC.
Is Inconel 625 hard to machine?
Nickel & cobalt base corrosion, temperature and wear-resistant alloys, such as Inconel 625, are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates.
How do you measure carbide inserts?
A two-digit number designates the sizes of these inserts. The first digit indicates the number of eighths of an inch in the width and the second digit indicates the number of fourths of an inch in the length of the insert.
