As a high-precision machine tool equipment, CNC vertical lathe plays an important role in the manufacturing industry. However, like all complex mechanical systems, CNC vertical lathes may also have some problems during use. The following is an analysis of some common problems with CNC vertical lathes:

1. Processing accuracy issues:

Inaccurate workpiece dimensions: This may be due to wear and tear caused by long-term high-speed operation of the CNC vertical lathe's carriage, screw rod, and bearings, or due to deviations in the tool holder's repetitive positioning accuracy. In addition, the high-speed rotation of the CNC vertical lathe spindle may also cause bearing wear, thereby affecting the processing dimensions.

Poor surface finish: Reasons may include damage to the CNC vertical turning tool tip, machine resonance, machine creep, or poor machining technology. The lack of sharpness of the CNC vertical turning tool or the uneven placement of the machine tool may lead to a decrease in surface finish.

2. Mechanical structure issues:

The workpiece has a tapered head phenomenon: This is usually caused by the horizontality of the CNC vertical lathe being not adjusted properly, or the material being too hard and the tool cutting too deep when turning the long axis. In addition, the non-concentricity of the tailstock ejector pin of the CNC vertical lathe and the spindle may also cause this phenomenon.

The driver phase light is normal but the processing size is unstable: This may be due to mechanical structural problems of the CNC vertical lathe, such as wear of the carriage, screw rod, and bearings, or bearing wear caused by the high-speed rotation of the spindle.

3. Operation and maintenance issues:

Improper operation: CNC vertical lathe operators do not follow correct operating procedures during operation, such as failing to adjust machine tool parameters in time or failing to replace worn tools or fixtures in time, which may lead to processing problems.

Insufficient maintenance: CNC vertical lathe equipment requires regular cleaning, lubrication and inspection to ensure its normal operation. Insufficient maintenance may result in machine tool performance degradation or even failure.

4. Electrical and control system issues:

Control system failure: The control system of the CNC vertical lathe is responsible for controlling the movement and processing process of the machine tool. If the control system fails, such as sensor damage, circuit failure, etc., it may cause the CNC vertical lathe to not work properly.

Aging of electrical components: Over time, the electrical components of a CNC vertical lathe may age, causing performance degradation or failure.

In order to solve these problems, a series of measures need to be taken, including:

1. Strengthen operational training: Ensure that CNC vertical lathe operators are proficient in the operating procedures and techniques of machine tools to improve processing accuracy and efficiency.

2. Regular maintenance: Carry out regular cleaning, lubrication and inspection of CNC vertical lathes to discover and solve potential problems in a timely manner.

3. Optimize the processing technology: According to the material and processing requirements of the CNC vertical lathe workpiece, select appropriate tools, cutting parameters and processing technology to improve the processing quality.

4. Update and upgrade equipment: For old CNC vertical lathes, you can consider updating and upgrading them to improve their performance and accuracy.

To sum up, the problems existing in CNC vertical lathes involve many aspects and need to be comprehensively considered and corresponding measures taken to solve them. By strengthening operational training, regular maintenance, optimizing processing techniques, and updating and upgrading equipment, the performance and stability of CNC vertical lathes can be effectively improved and provide strong support for the development of the manufacturing industry.
