With the rapid development of China's economy, labor costs are getting higher and higher, high-tech has also been widely used, and CNC machining centers have also been accepted by more and more manufacturers. However, due to various factors, my country has a considerable application level of some machining center users is not high, and the machine tool start-up rate and utilization rate are low, which directly affects the improvement of the economic benefits of machining center users. Common problems mainly consist of the following points:
1. Insufficient technical preparation
The main manifestations are that the tool preparation is not in place, the NC program is not compiled well, and the machine tool fixtures and measuring tools are not matched. Since the machining center is shut down to wait for the completion of the above work, the actual working time is directly affected.
2. low technical level
Including two aspects: First, the technical level of NC programming personnel is not high. The programming time is long, and the program is not concise and unreasonable, which leads to a long time for the machining center to stand by and debug the program, and even many functions of the machining center cannot be fully utilized. Second, the technical quality of the machining center operators is not high. It is mainly manifested in the slow understanding of NC programs, lack of knowledge of mechanical processing technology, poor comprehensive judgment and processing ability of various situations in machine tool processing, and small common faults that cannot be eliminated, etc., which make the non-processing operation and adjustment time of the machine tool too long.
3. poor management
Due to the short application time of machining centers in some enterprises, many enterprises lack the management experience of machining centers. Poor planning, poor scheduling, and poor logistics often occur in production, which makes the machine tool stand by for too long. In addition, quite a few users think that the machining center is precision equipment, and the general workpiece processing and rough machining processes are not arranged in the machining center, which artificially limits the processing objects to a small range, resulting in insufficient tasks. Some enterprises arrange workpieces that are not suitable for their processing or arrange some workpieces with poor rough quality in the machining center, resulting in frequent quality accidents during processing and affecting the start-up rate of the machine tool.
4. Improper selection
Due to improper selection of types and specifications of machining centers in some enterprises, they cannot be fully utilized, resulting in long-term idleness.
5. low reliability
The reliability of the machining centers used by some enterprises is not high, resulting in frequent failures, especially the automatic tool change system and the numerical control system often fails and causes downtime.
6. Weak maintenance force
At present, the maintenance force of most domestic machining center users is still very weak. Once a machine tool breaks down, it cannot be repaired quickly, and some even rely on the maintenance personnel of the manufacturer. In this way, it is bound to cause the machining center to stop working for a long time.
7. poor working environment
If the voltage of the power grid fluctuates too much, a sudden power failure, poor handling of the grounding wire of the machine tool, etc., the components of the CNC system may be damaged. In addition, too much dust, too high humidity, and too high room temperature are directly related to frequent failures of machine tools.
