Introduction to Factors Affecting the Machinability of Die Steel Materials

The chemical composition of steel is very important. The higher the alloy composition of steel, the harder it is to process. As the carbon content increases, the metal cutting performance decreases.


The structure of the steel is also very important for metal cutting performance. Different structures include: cast, cast, extruded, rolled and machined. Forgings and castings have very difficult to machine surfaces.


Hardness is an important factor affecting the metal cutting performance. The general rule is that the harder the steel, the harder it is to process. High speed steel (HSS) can be used to process materials up to 330-400HB; high speed steel + titanium nitride (TiN) coatings can process materials up to 45HRC; for materials with hardness 65-70HRC, Carbide, ceramic, cermet and cubic boron nitride (CBN) are used.


Non-metallic inclusions generally have an adverse effect on tool life. For example, al2O3 (alumina), which is pure ceramic, has a strong abrasiveness.


The last one is residual stress, which can cause metal cutting performance problems. It is often recommended to perform a stress release process after roughing.

Minimalist Wall Lamp

A minimalist style Wall Lamp is characterized by its simplicity and clean lines. It typically features a sleek and streamlined design, with minimal ornamentation or decorative elements. The focus is on functionality and minimalism, with a emphasis on using only essential materials and shapes.

Some common features of a minimalist style wall lamp include:

1. Simple geometric shapes: The lamp may have a basic shape, such as a rectangle or a cylinder, without any intricate details or embellishments.

2. Neutral colors: Minimalist wall lamps often come in neutral colors like white, black, or metallic finishes. These colors help to create a clean and uncluttered look.

3. Thin profile: The lamp may have a slim and slender profile, with a thin arm or base that extends from the wall. This helps to maintain a minimalist aesthetic and prevent the lamp from overpowering the space.

4. Integrated or hidden wiring: Minimalist wall lamps often have integrated or hidden wiring, which adds to the clean and seamless appearance. This means that the lamp is designed in a way that the wiring is not visible or distracting.

5. LED lighting: LED lights are commonly used in minimalist wall lamps due to their energy efficiency and sleek design. LED lights can be incorporated into the lamp in various ways, such as embedded strips or discreet bulbs.

Overall, a minimalist style wall lamp is a functional and stylish lighting option that complements modern and contemporary interiors. Its simplicity and clean lines make it a versatile choice for various spaces, from living rooms to bedrooms and even offices.
