It can be calculated using the following calculation method.

Vf (feed rate) = fz (feed amount per blade) × z( number of flutes ) × n (rotational speed)

number of flutes : Please check from the specifications of your indexable cutter or end mill.

Rotation speed (n): It can be calculated from the

The catalog condition table is an efficiency-oriented condition.

If you value more stable machining and tool life, we recommend the following adjustments.

・ Check the cutting conditions (rotation speed) of drills and taps from the bottom of the condition range in the catalog.

The amount of feed per rotation of the drill (mm/rev) is likely to affect the shape of the

Not only the base material of tools, but also various things have a relationship between "hardness" and "toughness".

The harder it is, the less likely it is to wear out, but it is easier to chipping .

The tougher it is, the more difficul

Depending on the characteristics (hardness and toughness) of the tool material, various types are used.

Hardness: The harder it is, the less likely it is to wear, but it is easy to break and chipping .

Toughness: The tougher it is, the harder it is to break, and the harder it is to chipping . If it is tough, it is easy

< Basics of Cutting (4) >, we will introduce "metal materials" among the main types of workpiece materials.

"Metal materials" can be roughly divided into "iron and steel" and "non-ferrous metals".

"Non-ferrous metals" include aluminum alloys and copper.

"Steel" is a general term for metal materials with iron as the main component.

If you look at t

There are various materials (= materials, workpiece materials) in the world, but they are classified according to the nature of the workpiece material.

Workpieces are broadly classified into " metallic materials " and " non-metallic materials ".

Typical examples of "non-metallic materials" include wood, paper, and plastic.

In general, how much harder should a cutting tool be than the material?

The approximate hardness of the workpiece material that can be processed is as follows.

・ Difference in hardness for stable machining: tool hardness -40HRC

・ Hardness difference that can be managed to be processed: Tool hardness -20HRC

The hardness
