Affect the surface polishing finish basic reasons

Adopt the method of grinding can make the mold surface is bright and clean, bright and clean degree is related to the following factors: (1). The quality of tool steel. Heat treatment process (3). Polishing technology and process equipment is generally thought that polishing process equipment is one of the most important influencing factors. Proper polishing technology and process equipment are of good quality of tool steel and heat treatment process of the right to get a satisfactory finish. On the other hand, even with the best quality steel will not achieve the specular effect. one Quality of tool steel on steel surface hardness uneven or feature differences tend to have an polishing difficult. All kinds of inclusions in steel and pores are not conducive to polishing. 2. Heat treatment process of heat treatment will affect the polishing performance in many ways. Surface hardening of the increase due to the surface of carbon steel in its subtle organization for polishing. Because small oxide particles on the surface of the steel increase make polishing difficult. Carburizing or decarburization on the surface of the steel will make hardness changes, making it difficult to polishing. Adopt the method of grinding can make the mold surface is bright and clean, bright and clean degree is related to the following factors: 1, steel quality ( On the steel surface hardness uneven or feature difference tends to increase the difficulty of polishing) 。 2, heat treatment process, Heat treatment would affect the polishing performance in many ways) 。 3, polishing technology ( Polishing process and polishing materials, the directly affect the polishing effect) 。 Polishing technology is often thought to be one of the most important influence factors, the proper polishing technology, the good polishing supplies, with good quality of tool steel and the correct heat treatment process to achieve a satisfactory finish. On the other hand, the polishing technology and consumptive use undeserved, even with the best quality steel will not achieve the specular effect.
