This article delves deep into the daily maintenance and fault prevention technology of the DC1317 CNC milling machine dedicated to plastic mold manufacturing by Ningbo Kaibo CNC Machinery Co., Ltd. Key maintenance processes such as guide rail lubrication cycle management, screw clearance detection, spindle temperature rise monitoring, and hydraulic system pressure inspection are highlighted.
Proper guide rail lubrication is crucial for the smooth operation of the CNC milling machine. The lubrication cycle should be strictly adhered to. Generally, for the DC1317 model, it is recommended to lubricate the guide rails every 8 - 10 working hours. This frequency can significantly reduce friction and wear, ensuring high - precision machining. A well - lubricated guide rail can extend the service life of the machine by up to 30% compared to machines with improper lubrication.
Screw clearance detection is another important aspect of maintenance. The allowable screw clearance for the DC1317 is within 0.01 - 0.02 mm. Any clearance beyond this range may lead to positioning inaccuracies during machining. Regularly monitoring the spindle temperature rise is also essential. The normal temperature rise of the spindle should be controlled within 30 - 40 degrees Celsius. Excessive temperature rise can damage the spindle bearings and affect the machining accuracy.
The hydraulic system pressure of the CNC milling machine directly affects the stability of the equipment. The normal working pressure of the hydraulic system for the DC1317 is between 10 - 15 MPa. If the pressure is too high or too low, it may cause abnormal vibrations, slow movement, or even system failures. Regular pressure inspections can help detect potential problems early and ensure the stable operation of the machine.
Common fault symptoms of the DC1317 include inaccurate positioning, abnormal vibrations, and alarm codes. For inaccurate positioning, the first step is to check the screw clearance and the guide rail lubrication. Abnormal vibrations may be caused by unbalanced tooling or loose components. When an alarm code appears, referring to the machine's manual for specific troubleshooting steps is necessary. By following a systematic fault diagnosis process, technicians can quickly identify and resolve problems, reducing machine downtime.
The DC1317 has a double - column structure, which is designed for long - term heavy - load operation. However, this also brings some maintenance challenges. The double - column structure requires more precise alignment and balance. Regularly checking the parallelism and perpendicularity of the columns is necessary to ensure the overall stability of the machine. In heavy - load environments, the wear and tear of components are more severe, so more frequent maintenance is required.
