There are a variety of factors that influence the cutting process of zinc alloy die casting from dsfsdf's blog

Different new materials have been developed and are now widely used as a result of the continuous advancement of manufacturing technology. Many of these new materials are difficult to process materials, such as zinc alloy die casting and composites, which are examples of this. One side of the coin is that significantly improves product performance, while the other is that it causes significant difficulties in the processing and manufacturing process. In order to complete tasks with high efficiency, low cost, high quality, and large quantities, it is critical to take the appropriate measures that are consistent with the characteristics of various difficult to process materials. These measures must be in line with modern science, technology, and industrial development requirements.

Factors affecting the machinability of various types of materials
1. toughness and abrasion resistance
In general, the higher the strength or hardness of zinc alloy die casting material is, the greater its cutting force, the higher its cutting temperature, and the greater its tool wear. Furthermore, when cutting hard materials, the tool chip contact length is short, and the cutting force and cutting heat are concentrated near the cutting edge, making it easy for the cutting edge to peel off or even collapse. This is especially noticeable when using brittle tool materials such as cemented carbide and ceramics, which are particularly susceptible to this problem. As a result, the material's cutting and machinability are both inadequate.

2. plasticity and tensile strength
Increased chip deformation, increased cutting heat, and ease of bonding between tool and die casting material are all associated with increased plasticity and toughness of zinc alloy die casting material. As a result, the tool wear will be aggravated even further. However, if the plasticity and toughness of the workpiece material are too low, the tool chip contact length will become extremely short, resulting in significant tool wear. Thus, machinability of workpiece materials with excessive or insufficient plasticity and toughness is compromised.

3. resistance to high temperatures
With improved heat resistance, zinc alloy die-casting material can maintain high strength and hardness even at high temperatures, making zinc die casting extremely difficult to cut and form into shapes.

4. The ability of tools to scratch
The greater the scratch resistance of zinc alloy die casting material, the greater the tool wear and the poorer the machinability of the material.

Thermal conductivity is a property that can be measured.

The lower the thermal conductivity of zinc alloy die casting material, the less heat is transmitted during the cutting process, the higher the cutting temperature, the more serious tool wear, and the worse the machinability of the material.
