Ningbo Kaibo CNC Machinery Co., Ltd. is a well - known player in the field of CNC machinery, and its DC1317 large - double - column CNC milling machine is a high - performance product favored by many customers. This article will comprehensively introduce the daily maintenance and troubleshooting methods of this machine, aiming to help technicians ensure its efficient and stable operation.
Proper daily maintenance is the key to extending the service life of the DC1317 CNC milling machine. Here are some essential maintenance operations:
The guide rails of the DC1317 need regular lubrication. It is recommended to lubricate the guide rails every 8 - 10 hours of operation. This helps reduce friction and wear, ensuring smooth movement of the machine components. For example, if the machine runs continuously for a long time, the lubrication interval should be shortened appropriately. A well - lubricated guide rail can improve the machining accuracy of the machine by up to 20%.
Checking the clearance of the ball screw is also crucial. Technicians should measure the ball screw clearance at least once a month. Excessive clearance can lead to positioning errors during machining. By regularly detecting and adjusting the ball screw clearance, the positioning accuracy of the machine can be maintained within ±0.02mm.
The spindle is the core component of the milling machine. During operation, the spindle temperature should be monitored in real - time. Generally, the normal operating temperature of the spindle should be controlled between 40 - 60°C. If the temperature exceeds 60°C, it may indicate a problem with the spindle bearing or lubrication system, and immediate inspection is required.
The hydraulic system of the DC1317 provides power for various components. The hydraulic pressure should be checked at least once a week. The normal working pressure of the hydraulic system is about 10 - 15 MPa. Any significant deviation from this range may cause abnormal operation of the machine.
Even with proper maintenance, problems may still occur. Here are some common faults and their solutions:
If the machine has problems with fault location, technicians can first check the electrical connections and sensors. In many cases, loose electrical connections or sensor failures can cause inaccurate fault location. According to statistics, about 30% of fault location inaccuracies are caused by electrical connection problems.
Abnormal vibration during machine operation may be due to unbalanced cutting tools, loose machine components, or improper spindle rotation. Technicians can start by checking the cutting tools and tightening loose components. If the problem persists, a more in - depth inspection of the spindle system is required.
The DC1317 is equipped with an alarm system. When an alarm code appears, technicians can refer to the machine's manual for detailed analysis. For example, if the alarm code indicates a problem with the coolant system, technicians should check the coolant level, pump operation, and pipeline blockage.
The double - column structure of the DC1317 is designed for high - load operations. However, this also means that it has special maintenance requirements. Under high - load conditions, the stress on the columns and other components is greater. Therefore, technicians should pay more attention to the deformation and wear of these components. Regularly check the parallelism and perpendicularity of the columns, and adjust them in time if necessary.
