How do I check the condition of my equipment when buying a used AgieCharmilles CUT C350 jogging wire?

When buying a used AgieCharmilles CUT C350 jogging wire, you can check the condition of the equipment in the following ways:
1. **Appearance check**
    - Check whether the overall appearance of the equipment has obvious bumps, scratches, deformation, etc., especially the key parts of the machine tool such as the table, guide rail, silk rod, etc., if there is damage that may affect the accuracy and stability of the equipment.
    - Check whether the shell of the equipment is complete, whether the connection of the components is tight, there is no loose, off the phenomenon, to avoid vibration due to the shell or components are not firmly installed, affecting the machining accuracy.
    - Observe whether the power line, signal line and other cables of the equipment are broken, aging, exposed, etc., to prevent electrical failures caused by cable problems.
2. **Precision testing**
    - Use laser interferometer and other professional equipment to detect the positioning accuracy and repeat positioning accuracy of each axis of the machine tool. The positioning accuracy of the AgieCharmilles CUT C350 slow-feeding wire should usually be about ± 0.002mm, and the repeat positioning accuracy should be higher.
    - Check the flatness of the table, you can use a level meter to measure, the flatness error should be within the specified range, otherwise it will affect the clamping and machining accuracy of the workpiece.
    - Perform verticality and straightness checking, such as checking the verticality of Z-axis and table, straightness of X-axis and Y-axis, etc. Tools such as right-angle ruler and laser collimator can be used to ensure the accuracy of the movement of each axis.
3. **Mechanical component inspection**
    - Checking the wear and tear of the silk rod and guide rail can be done by observing the surface for signs of wear and measuring the pitch error of the silk rod. If the silk rod and guideway are seriously worn, it will lead to a decrease in the precision of the machine movement and affect the machining quality.
    - Check whether the wire-walking system is normal, including whether the tension control of the electrode wire is stable, whether the wire guide nozzle is worn out, and whether the wire-walking speed is uniform. The stability of the wire-walking system is directly related to the machining accuracy and surface quality.
    - Check the transmission components, such as gears, belts, couplings, etc., to see if there are loose, worn, broken, etc., to ensure the reliability of the transmission system, to avoid machining errors due to transmission failure.
4. **Electrical system check**
    - Check the electrical components in the control cabinet for signs of aging, damage, overheating, etc., such as whether the capacitor is bulging, whether the resistor is discolored, and whether the relay has an abnormal ringing sound. If there are damaged electrical components, they should be replaced in time so as not to affect the normal operation of the equipment.
    - Check whether the layout of the electrical wiring is neat and standardized, and whether there are any short-circuits, broken circuits and other problems. At the same time, check whether the grounding is good to ensure the safety of the equipment.
    - Test the various electrical properties of the equipment, such as whether the input voltage and current are normal, and whether the power supply of each functional module is stable.
5. **Pulse power supply check**
    - Check whether the output parameters of the pulse power supply are normal, including pulse width, pulse frequency, discharge current, etc., which can be measured by using professional test instruments. The performance of pulse power supply directly affects the processing efficiency and processing quality.
    - Observe whether the pulse power supply has abnormal discharge phenomenon when working, such as unstable discharge, arc discharge, etc. If there is any abnormality, the power supply system may be faulty, which requires further inspection and repair.
6. **Control system check**
    - Check whether the operation interface of the control system is displayed normally and whether the function buttons are sensitive and effective. At the same time, check whether the software version of the control system is the latest version, and upgrade it if necessary.
    - Test whether the functions of the control system, such as automatic programming, manual operation, processing parameter setting, fault diagnosis, etc. are normal. Test the stability and reliability of the control system through actual operation.
    - Check whether the communication between the control system and the various components of the machine is normal to ensure that the instructions can be transmitted accurately and without error to avoid machining errors due to communication failures.
7. **Machining capability test**
    - Conduct trial machining, select suitable workpiece materials and machining processes, process some representative parts, such as precision molds, complex shaped parts, etc., and test the equipment's machining accuracy, surface quality, machining efficiency and other performance indicators through actual machining.
    - In the trial machining process, observe the running status of the equipment, whether there is abnormal sound, vibration and other conditions. At the same time, check whether the dimensional accuracy and surface roughness of the processed parts meet the requirements, so as to evaluate the comprehensive processing capability of the equipment.
