Reasons for the formation of metal medals
Every metal medal must be made and carved with heart. The effect of metal medal production directly affects the quality of sales, so the production of metal medals is the key. How are metal medals shaped? Let's take a look at it together.
How are metal medals formed?
Mechanical molding is widely used in the production of metal medals, which is closely related to the characteristics of the material. The production of metal medals usually uses stainless steel with a high melting point , Casting is difficult, and the hardness of stainless steel for metal medals is low, and it has a certain degree of plastic processing performance. With appropriate machining process parameters and processing equipment, high-quality metal medals can be obtained. The following is the forming process of metal medals:
Using a lathe to directly process stainless steel metal profiles into medals, it is the most common in ring and bracelet medals, accounting for a large proportion. They are stainless steel shank and Qin alloy shank turned by a lathe. Due to the respective material characteristics of stainless steel and titanium alloy, there are certain difficulties in turning. It is necessary to select and formulate corresponding processing parameters according to the characteristics of the materials to ensure the processing accuracy and surface quality of the medals.
Some friends in the basin have encountered difficulties in stainless steel cutting, don’t know what to do? Now we will analyze the reasons for the difficulties in stainless steel cutting, and hope to help you:
1. The thermal conductivity is low, and the cutting heat cannot be dissipated in time. The heat transferred to the tool can reach 20%, and the cutting edge of the tool is prone to overheating and loses cutting ability.
2. Strong chip adhesion, prone to knife edge. Stainless steel has high adhesion, which will cause the material to 'stick' on the tool during turning, resulting in 'knife edge'.
3. Chips are not easy to break. In the metal cutting process, the forming process of plastic material (ductile material) chips has undergone four stages of extrusion, slippage, squeezing and separation.
4. The work hardening tendency is strong, which makes the tool easy to wear. The processing tendency of stainless steel is strong, the hardness of the work hardening layer is high, and it has a certain depth of work hardening, which increases the difficulty of processing and tool wear.
Metal medal production should not only emphasize quality, but now people pay more attention to the meaning of medals and the meaning of such production. Medals are originally a special product, with its senior and special significance. Therefore, the meaning of medal production must be positive and motivate people to work hard. Medals are originally a reward and an incentive for successful people.
