How to tell if the performance of Hammar N80 hobbing machine is stable?

To determine whether the performance of Hamai N80 hobbing machine is stable, you can start from the following aspects:
1. Check the history of the equipment
- **Maintenance records**: detailed view of the equipment maintenance files, if frequent maintenance due to failure of key components, such as spindles, feed shafts, etc. appeared many maintenance records, may mean that there are design defects in the equipment or long-term use of serious wear and tear caused by the stability of performance in doubt.
- **Use records **: to understand the frequency of use of the equipment and the use of the environment. If the equipment in a short period of time, the frequency of use is extremely high, or long-term work in harsh environments (such as high temperature, high humidity, dusty), may accelerate the aging and wear of the equipment, affecting the performance stability.
2. Appearance and internal inspection
- **Appearance check**: Observe the equipment as a whole with or without deformation, bumps, paint and so on. Focus on viewing the guide rail, table and other key parts, if there is obvious wear and tear, scratches or rust, may affect the movement accuracy and stability.
- **Internal Inspection**: Open the protective door of the equipment and the electrical cabinet, and check the mechanical parts such as gears, screws, couplings, etc. for wear and tear, looseness, deformation, as well as electrical components for signs of aging, damage, overheating. If there are such problems, it may lead to vibration, noise, precision degradation and other unstable phenomena when the equipment is running.
3. Test equipment running status
- **No-load running test**: Let the equipment run unloaded for more than 30 minutes, and observe whether the movement of each coordinate axis is smooth and steady, and whether there is any vibration, noise, stuttering or abnormal heating phenomenon. Check whether the instruction execution of the control system is accurate and whether the display of each parameter is normal.
- **Load running test**: carry out load running test, which can be selected to process different types and precision requirements of gear workpieces. Observe the stability of the equipment in the cutting process, such as whether the spindle speed is stable when the cutting force changes, whether the feed movement is uniform, and whether there is any vibration or displacement due to force. At the same time, test whether the accuracy of the processed workpiece meets the requirements, such as tooth shape, tooth direction, tooth pitch and other errors within the tolerance range. Repeated processing tests, if the consistency of workpiece accuracy is good, the equipment in the load state performance is stable.
4. Evaluation of CNC system performance
- **System function test**: Check whether the functions of the CNC system are normal, such as manual operation, automatic programming, data transmission, tool compensation and other functions are accurate. Test the response speed of the system, after the instruction is issued, the various components of the equipment should be able to quickly and accurately execute the action.
- **System Stability Test**: Run the simulated machining program or complex macro program of the CNC system for a long time, and observe whether the system will crash, alarm or data loss and other abnormalities. If the system is stable and reliable over a long period of time, it means that the CNC system has good performance and can provide a guarantee for the stable operation of the equipment.
5. Reference to user reviews and brand reputation
- **User evaluation**: Consult with other users who have used Ahmadiyah N80 hobbing machine to understand their experience and evaluation in actual use. Focus on the performance of the equipment in the process of prolonged use, whether frequent failures, as well as the timeliness and effectiveness of after-sales service.
- **Brand reputation**: Investigate the reputation and word of mouth of Hammar brand in the field of hobbing machines. Understand the brand's products in the market recognition, quality and reliability, as well as technical support efforts. A hobbing machine with a good brand reputation usually has a better performance stability.
