Metal cutting (How E.W is made)

We will introduce you to the processing of cutting various metals.
There are various types of metals such as iron, stainless steel, aluminum and copper, and the shapes are also vary.
Before cutting, we choose machine and processing based on material shape, such as round rod-shaped or square materials.

<Q&A>
・ What kind of metal EXT Engineer can cut?
Iron, stainless steel, aluminum, copper, and brass are common, but we also can cut special metals such as titanium.

・How big is the size that can be cut?
A round size is φ250mm, and a square size is around 300mm x 300mm.

・Is it possible to see the cutting process？
Yes, it is. It will be easier to imagine how metal cutting is performed at the factory.

There are two ways to cut metal: by rotating the metal itself or by rotating the cutting tool. Because hard items come into touch with each other, heat is generated in both circumstances. As a result, cutting fluid is used to keep the metal cold while it is being cut.

Machined parts ①

This is a part cut from a round stainless steel material. We use lathe machine to cut round materials. A lathe cuts a material by applying a cutting tool to the rotating material.
This is an image of a potter's wheel that reminds me of Ghost movie.
(Pottery to make ⇒ parts to be cut, human hands ⇒ cutlery).
Parts are cut with precision of 1/1000mm. The screw is processed and the tip is cut so that a wrench can be inserted for easy tightening.

Machined parts②

We made this shape from a block-shaped titanium material. We did not use lathe machine for this processing. Without rotating, we fixed the material then rotated a cutting tool to shave the material. Imagine the dentist work, teeth ⇒ parts to be shaved, rotating blades to shave teeth ⇒ blades to shave metal.

Coloring the cut parts.

It is possible to color the cut parts in order to strengthen the surface or vary the look. The color changes depending on the type of metal.
(Example: Iron ⇒ Black or silver, Stainless steel ⇒ As it is, Aluminum ⇒ Almost any color is possible)
