In the field of mold manufacturing, high-precision and high-speed equipment is crucial for achieving excellent product quality and high efficiency. This article delves into the practical application and process parameter optimization of the high-precision high-speed CNC milling machine GJ8070 under Ningbo Kaibo CNC Machinery Co., Ltd. in mold manufacturing.
The high-speed vertical machining center GJ8070 is equipped with the Fanuc control system and HSK high-speed spindle, which are the key factors ensuring high precision and stability in mold processing. The Fanuc control system, known for its high reliability and advanced control algorithms, can precisely control the movement of the machine tool axes, with a positioning accuracy of up to ±0.005mm. The HSK high-speed spindle, with a maximum speed of 12,000 rpm, can provide high torque at high speeds, enabling efficient and precise cutting of various mold materials.
Thermal deformation and vibration are two major problems in mold processing, which can affect the surface quality and dimensional accuracy of the mold. To address these issues, the GJ8070 adopts advanced thermal deformation control and vibration suppression technologies. For example, the machine tool is equipped with a thermal compensation system, which can detect the temperature change of the machine tool in real-time and adjust the machining parameters accordingly, reducing the thermal deformation error to less than 0.01mm. In terms of vibration suppression, the machine tool uses a damping structure design and a dynamic balancing system, which can effectively reduce the vibration amplitude during machining, improving the surface roughness of the mold to Ra 0.8μm.
Proper process parameter setting is the key to improving machining efficiency and quality. This article shares practical experience in process optimization, including the selection of cutting speed, feed rate, and cutting depth. For example, when machining hardened steel molds, a cutting speed of 80-120 m/min, a feed rate of 0.1-0.2 mm/r, and a cutting depth of 0.2-0.5 mm are recommended. By optimizing these parameters, the machining efficiency can be increased by 30% and the tool life can be extended by 20%.
The selection of tool materials and cutting fluids also has a significant impact on the machining effect. Different mold materials require different tool materials. For example, for aluminum alloy molds, carbide tools are recommended; for high-hardness steel molds, cubic boron nitride (CBN) tools are more suitable. In addition, the right cutting fluid can reduce the cutting temperature, improve the surface quality of the mold, and extend the tool life. Water-based cutting fluids are widely used in mold processing due to their good cooling and lubricating properties.
To illustrate the effectiveness of the GJ8070 in mold manufacturing, this article presents several typical application cases. For instance, a mold manufacturing company used the GJ8070 to process a complex automotive mold. By optimizing the process parameters and using appropriate tool materials and cutting fluids, the company reduced the machining time by 40% and improved the dimensional accuracy of the mold to within ±0.01mm, meeting the high requirements of the automotive industry.
