Types of cutting
Cutting things is called "cutting", isn't it? However, even if you say "cutting" in one word, there are various cutting methods and tools to use.
Let's take a look at the things around us. Do you see any "cutting" tools?
The things that we feel most familiar with are blades such as scissors and knives, and mechanical ones such as saws.
But that's not the only type of "cutting".

But that's not the only type of "cutting".
Those that use thermal energy such as gas cutting, those that use energy such as electricity, light, and electromagnetic waves such as lasers, etc.
With the development of technological development in recent years, the cutting work has also evolved.

Cutting with abrasive grains is also called "cutting", and each of the abrasive grains becomes a blade, and cutting proceeds by scraping the surface.
Don't you think you are using more energy to cut things than you think?
There are so many types of typical "cutting" alone.
The development of these technologies supports the current "manufacturing".
Features of cutting wheel
Why can a cutting wheel cut things?
The cutting wheel is composed of three elements: "abrasive grains", "binder", and "pores".
With these three elements in place, the cutting wheel becomes a tool for cutting things.
It is equivalent to a blade that sharpens an object.Each abrasive grain becomes a blade and scrapes the work piece.

Binder
| It is a combination of abrasive grains and abrasive grains.
|
Pore
| The gap required to remove chips.
Chips enter these pores and are ejected while the grinding wheel is rotating. |
By rotating the cutting wheel at high speed, innumerable sharp abrasive grains can be used as cutting edges to quickly cut workpieces and cut them to a beautiful finished surface and the correct dimensions.
As the abrasive grains wear, new cutting edges are created, and if they fail, they fall off and the next new abrasive grains are created.
(This phenomenon is called "self-sustaining action".)
Therefore, the cutting wheel can continue to work in the same state. (See the figure below)

This is the biggest feature of the cutting wheel, which is not found in other cutting tools.

Other cutting methods
Introducing other cutting methods.
Water jet cutting
High-pressure water generated by an ultra-high pressure pump is squeezed to a diameter of 1 mm or less with an orifice (a hole for controlling the flow rate of fluid) in the nozzle holder, and an abrasive such as garnet is mixed into this to dramatically cut the cutting ability. It is a cutting method that enhances.
Laser cutting
Laser cutting is a processing method in which a condensed laser is directly applied to a sample to melt it, and the molten metal is blown off by an assist gas flowing coaxially with the laser to cut it.
Gas cutting
This is a cutting method called fusing (heat cutting).It is a method of melting and cutting metal with the heat of gas.
This includes plasma cutting and laser cutting.
This includes plasma cutting and laser cutting.
Bandsaw cutting
The band saw is also called a "band saw board", and a band-shaped saw blade cuts the work (workpiece) by continuous drive.
The pitch (number of ridges for 1 inch (25.4 mm)) is selected according to the work and material specifications, but there is also a combination pitch that supports a wider range of work materials.
Metalsaw disconnection
Cut the material with a round saw blade.
A good cutting surface can be obtained with higher accuracy than conventional cutting machines, and high-speed cutting is possible.
There are various pitches and blade shapes depending on the work material and material specifications, and there are also various surface treatments.
Tip saw disconnect
Low-speed cutting that can quickly cut various steel materials.
Compared to a grindstone cutting machine, the cutting time can be shortened to 1/3 to 1/5, and there is less sparks and dust during cutting, enabling clean cutting that does not leave burns or burrs on the cut surface.
