What do I need to look for in a used AgieCharmilles CUT C350 jogging wire?

When buying a used AgieCharmilles CUT C350 jogging wire, you need to consider the condition of the equipment, performance tests, after-sales guarantee and other aspects to ensure that you buy a device that meets your needs and is of reliable quality. Specific considerations are as follows:
1, equipment condition check
- ** Appearance and mechanical structure **: Observe the appearance of the equipment has no obvious damage, deformation, paint is peeling. Check the wear and tear of the table, screw, guide and other mechanical parts to ensure that the table moves smoothly, screw, guide without obvious scratches and wear, otherwise it will affect the processing accuracy and stability.
- **Electrical system**: Check whether there are signs of aging and damage to the electrical components in the electrical cabinet, and whether the wiring is neat and undamaged. Check whether the grounding of the equipment is good to prevent leakage and other safety hazards. At the same time, find out the version of the control system of the equipment and whether it needs to be upgraded to meet the current processing requirements.
- **Water Tank and Cooling System**: Check whether there is water leakage in the water tank, whether the water quality is clean, whether the pipeline of the cooling system is smooth, and whether the water pump works normally. If there are problems with the cooling system, it will affect the cooling effect of the electrode wire and the workpiece during the machining process, which in turn will affect the machining quality.
- **Wire walking system**: Check whether the tension mechanism of the electrode wire is working properly, whether the electrode wire is running smoothly, and whether there is any jittering or deflection phenomenon. In addition, check the wear of the wire storage cylinder, if the wear is serious, it may lead to untidy winding of the electrode wire, affecting the machining accuracy.
2、Performance test
- **Precision test**: Ask the seller to provide the precision test report of the equipment, or use the standard test piece for processing test, measure the deviation of the processing size from the design size, and evaluate whether the processing precision of the equipment meets your production needs. Focus on checking the positioning accuracy and repeat positioning accuracy of X, Y and Z axes, as well as the motion accuracy of U and V axes.
- **CUTTING SPEED AND SURFACE QUALITY**: Observe whether the cutting speed of the equipment is normal and whether the roughness of the cutting surface meets the requirements through actual cutting tests. Different processing parameters will have an impact on the cutting speed and surface quality, so it is important to test under a variety of parameter conditions to fully assess the performance of the equipment.
- **Functional Integrity Test**: Check whether the various functions of the equipment are complete and can operate normally, such as automatic threading function, taper cutting function, graphic programming function, etc.. For equipment with intelligent functions, but also to test its intelligent control system is working properly, whether it can achieve automatic optimization of processing parameters and other functions.
3, equipment history and maintenance
- * * * years of use and hours * * *: to understand the factory date of the equipment and the actual number of hours of use, in general, the use of a short period of time, the number of hours of equipment, the wear and tear of its components is relatively small, relatively good performance. However, it is also necessary to combine the use of equipment and maintenance of the environment and comprehensive judgment.
- **Maintenance records**: Ask the seller for the equipment's maintenance records to find out whether the equipment has had major failures, as well as the parts and frequency of maintenance. Frequent repairs may mean that there are potential quality problems with the equipment, while good maintenance records show that the seller pays more attention to the maintenance of the equipment, the reliability of the equipment may be higher.
- **Maintenance**: Ask the seller about the daily maintenance of the equipment, including maintenance intervals, lubricants used, frequency of replacement of electrode wires and working fluids. Regularly regulated maintenance of the equipment, the service life of its components will be extended, the performance can also be better maintained.
4, after-sales protection and contract signing
- **After-sales service**: Negotiate with the seller to determine the terms of after-sales service, including the installation and commissioning of the equipment, training of operators, the warranty period, as well as the responsibility for maintenance during the warranty period and bear the costs. Understand whether the seller has a professional after-sales service team, and whether it can respond to and solve the problems arising from the use of the equipment in a timely manner.
- **Accessories supply**: Confirm whether the commonly used accessories of the equipment are easily accessible and whether the seller can provide accessories supply guarantee. Some imported equipment parts may have a long supply cycle, high prices, which will affect the timeliness of maintenance and the use of equipment costs.
- **Contract signing**: Sign a detailed purchase contract, clear equipment models, specifications, configuration, price, delivery time, payment methods, after-sales protection and other terms, to avoid disputes without evidence to rely on. At the same time, the acceptance criteria and methods of equipment should also be clearly specified in the contract to ensure that the equipment purchased meets your expectations.
