A machining center is a highly precise machine tool equipment that plays a crucial role in modern manufacturing. In order to ensure the normal operation and efficient production of the machining center, its installation requirements, environmental conditions, and preparation work before operation are particularly important. This article will discuss in detail the installation requirements, environmental requirements, and preparation work required before operation of the machining center.
1、 Installation requirements and environmental requirements
1. Basic installation: The machining center should be installed on a solid foundation, and the stability of the foundation has a direct impact on the accuracy and performance of the machine tool. The position should be away from the vibration source, such as avoiding approaching large mechanical equipment, punching machines, etc., to reduce the impact of vibration on the machine tool. Meanwhile, in order to prevent the transmission of vibration, anti vibration trenches can be set up around the foundation.
2. Environmental conditions: The machining center should be placed in a dry and well ventilated place to avoid interference from moisture and airflow. Excessive humidity may cause electrical component failures, while unstable airflow can affect the machining accuracy of the machine tool. In addition, the machine tool should also avoid sunlight and thermal radiation to prevent temperature changes from having a negative impact on the accuracy of the machine tool.
3. Horizontal adjustment: During the installation process, the machine tool needs to be horizontally adjusted. A spirit level can be used for measurement to ensure that the flatness of the machine tool meets the requirements in its free state. For ordinary machine tools, the level reading should not exceed 0.04/1000mm, while for high-precision machine tools, the level reading should not exceed 0.02/1000mm. The accuracy of horizontal adjustment is crucial for the movement accuracy and machining quality of machine tools.
4. Avoid forced deformation: During the installation process, try to avoid using installation methods that may cause forced deformation of the machine tool. The various components of the machine tool should be installed in a free state, and the anchor bolts should be evenly locked to ensure the overall stability of the machine tool.
5. Component protection: During installation, attention should be paid to protecting all components of the machine tool. Do not disassemble certain components of the machine tool at will, as the disassembly of these components may cause a redistribution of stress within the machine tool, thereby affecting its accuracy.
2、 Preparation work before operation
1. Cleaning and lubrication: Before operating the machining center, it is necessary to thoroughly clean the machine tool. You can use cotton or silk cloth soaked in cleaning agents for wiping, but be careful to avoid using cotton or gauze to prevent residual fibers from entering the interior of the machine tool. After cleaning, lubricating oil specified for the machine tool should be applied to each sliding surface and working surface to ensure smooth operation of the machine tool.
2. Geometric accuracy inspection: The geometric accuracy of the machine tool is the key to ensuring machining accuracy. Before operation, it is necessary to inspect the geometric accuracy of the machine tool to ensure that it meets the requirements. Only after passing the inspection can the next step of operation be carried out.
3. Check lubricating oil and coolant: Carefully check whether all parts of the machine tool have been lubricated as required, especially the guide rail surface and machining surface. At the same time, check if there is enough coolant added to the cooling box to ensure that the cooling system is working properly.
4. Check the electrical control box: Check whether all switches and components in the electrical control box are normal, and ensure that all plug-in integrated circuit boards are installed properly and there is no looseness.
5. Power on preheating: Start the centralized lubrication device by powering on, so that each lubrication part and lubrication oil circuit are filled with lubricating oil. This can reduce the wear of the machine tool in the early stages of operation and extend the service life of the equipment.
6. Preparation confirmation: Before operating the machining center, it is necessary to carefully check whether all components of the machine tool have been prepared according to the requirements. Including checking whether the installation of cutting tools and fixtures is firm, and whether the clamping of the workpiece is stable.
In order to ensure the movement accuracy and normal operation of the machining center, strict implementation of installation requirements and environmental conditions, as well as meticulous preparation work before operation, are essential. Only under such circumstances can the machining center unleash its efficient and precise processing capabilities, providing reliable guarantees for the production of enterprises.
Throughout the entire process, we must always bear in mind the importance of machining centers and strictly follow the relevant requirements for operation. The normal operation of machining centers not only affects production efficiency and product quality, but also directly affects the economic benefits and market competitiveness of enterprises. Therefore, we must attach great importance to the installation and operation of the machining center, ensuring that every step is done properly.
I hope this article can provide useful references for machining center manufacturers and operators, helping everyone better understand and master the installation requirements and preparation work before operation of machining centers. Let's work together to create a more stable and efficient processing environment, and contribute to the development of the manufacturing industry.
