Metal Cutting Inserts VBMT To Machining Stainless Steel For Cnc Toolholder

Specification of Tungsten carbide inserts VBMT:

How to choose correct turning inserts:

There are many parameters to consider when choosing a turning insert. Carefully select insert geometry, insert grade, insert shape (nose angle), insert size, nose radius and entering (lead) angle, to achieve good chip control and machining performance.

• 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
• Select a smaller nose radius if there is a tendency for vibration

Turning insert grade:

The insert grade is primarily selected according to:

• Component material (ISO P, M, K, N, S, H)
• Type of method (finishing, medium, roughing)
• Machining conditions (good, average, difficult)

The insert geometry and insert grade complement each other. For example, the toughness of ​a grade can compensate for lack of strength in an insert geometry.

Factors that influences chip breaking:

• Insert geometry: Based on the width of chip room and the design of micro- and macro-geometry, the chip can be opened or more compressed
• Nose radius: Smaller nose radius controls the chip more than a bigger nose radius
• Entering (lead) angle: Depending on angle, the chip is directed in different ways: toward shoulder or out from shoulder
• Cutting depth: Depending on the workpiece material, a larger cutting depth will influence the chip breaking, leading to bigger forces to break and remove the chip
• Feed: A higher feed will generally create stronger chips. In some cases, it can help chip breaking and chip control
• Cutting speed: Change of cutting speed can influence the chip breaking performance
• Material: A short-chipping material (for example cast iron) is generally easy to machine. For materials with excellent mechanical strength and resistance to creep
  (the tendency for solids to slowly move or deform under stress, for example, Inconel), chip breaking is of greater concern
