12. Provide traditional Chinese and English interfaces, easy to operate.

The spindle running in measurement and control system of machine tools has important practical significance:

1. It solves the problems of low precision, low efficiency, and resource waste in manual operation during the spindle running in process.

2. By quantifying loading, online monitoring, chart analysis, etc., the manufacturing and assembly quality of the transmission system of the machine tool spindle can be more scientifically reflected, and the quality of the spindle can be judged.

3. Through the accumulation of experimental data over a certain period of time, regular problems in product quality can be summarized and analyzed, which can guide technological transformation and product updates in the production process.

4. It can eliminate the hidden dangers of accidents caused by human factors.

Product Features:

1. Easy to operate, can indeed monitor/ensure the performance of the spindle
2. Intelligent running in process control, providing professional spindle performance running in/testing
3. Humanized spindle temperature rise curve recording chart and numerical table, which can conveniently/distinguish the relevant performance of the spindle
4. Equipped with temperature sensor self detection function, the system will automatically sound an alarm when a sensor abnormality occurs during the monitoring process
5. Equipped with a safe running in design function, it will not affect the running in program during execution in case of sudden or triggered computer crashes
6. In the event of an electrical malfunction at any time, the system will still complete all running in procedures. But the records cannot be saved after the machine crashes
7. Traditional Chinese can be provided Simplified Chinese Three types of program installation environments in English, as well as operation interfaces for monitoring tasks



Technical principle:

With the rapid development of high-speed machining, the requirements for the spindle of CNC machine tools are also increasing, and the heating of the spindle has become a major problem that needs to be solved.
Excessive temperature causing thermal deformation of the spindle will seriously reduce the machining accuracy and rotation accuracy of the machine tool. In severe cases, it can burn the bearings and reduce the service life of the spindle,

Precise temperature rise and running in of the spindle are particularly important in the early stage

Run in ensures even distribution of lubricating grease within the spindle:
The main heat source of the spindle is the heat generated by the high-speed rotation of the bearing. Improper lubrication affects 60% -70% of the performance of bearings and also determines the quality of the spindle. Basically, it happened
When there is abnormal noise, the temperature of the spindle will increase accordingly, and as the sound increases, the temperature rise will also increase, and the vibration will also increase.

Main spindle running in temperature rise detection

Statistical data shows that the proportion of mechanical system failures in China is 39.7% for hydraulic systems, 14.8% for power systems, and 14.5% for transmission and walking systems
The working device is 8.4%, the electrical system is 8.1%, and the braking system is 5.6%.

Running in experiments can detect early faults
The running in test can fully expose early quality issues of the hydraulic, power, and walking systems of the spindle.
In order to achieve early diagnosis of CNC machine tool failures and avoid component losses during failures, experiments were conducted by testing the front and middle bearings of the spindle
Detecting the temperature of the rear bearing, monitoring the temperature changes of the spindle system, and setting high temperature alarm parameters according to national standards.

The important role of temperature rise curve chart
The system displays the temperature value, speed, and temperature change history curve of the spindle in a chart format, achieving monitoring, warning, and controlling the safe speed of the spindle,
Analyze the temperature rise status of each stage through curve analysis,Speed operation status.
When the temperature exceeds the standard specification, it will automatically stop running to protect the spindle.
