Wire-cut EDM equipment with high-speed wire movement is widely used in mold manufacturing, mechanical processing and other fields for its efficient and flexible machining characteristics. Standardized maintenance is the key to the stable operation of the equipment. The following details the full maintenance process from three aspects: daily, regular and long-term.
1. Daily Maintenance: Eliminate Hidden Hazards in Time
Before each use, carry out basic inspections on the equipment:
- First, check whether the worktable surface is flat and free of debris to ensure the workpiece is clamped firmly.
- Then, inspect the tension of the electrode wire. Excessive looseness easily causes wire breakage, while excessive tightness increases molybdenum wire wear. Adjust it to an appropriate state through the tension adjustment device.
- During operation, pay attention to the running sound of the equipment. If abnormal friction or vibration occurs, stop the machine immediately for troubleshooting.
- After use, clean the chips and impurities on the worktable and in the working fluid tank to prevent chip accumulation from scratching the worktable. Meanwhile, check the concentration of the working fluid and promptly replenish or replace the contaminated fluid.
2. Regular Maintenance: In-Depth Component Maintenance
- Weekly Inspection: Conduct an in-depth check on the equipment, focusing on: Cleaning the surface of the conductive block. Long-term use can form grooves on the conductive block surface, leading to poor contact between the electrode wire and the block. Gently polish it with sandpaper or replace the conductive block if necessary. Checking the rotation flexibility of the guide wheels. If the guide wheels do not rotate smoothly, it will affect the motion precision of the electrode wire. Add lubricating oil or replace the worn guide wheel bearings.
- Monthly Inspection: Check the verticality and positioning accuracy of the equipment, and use professional tools for calibration to ensure machining precision.
- Quarterly Maintenance: Dust the electrical components in the control cabinet to prevent short circuits caused by dust accumulation.
3. Long-Term Maintenance: Ensure Equipment Performance
- Semi-Annual Maintenance: Carry out a comprehensive maintenance, including: Disassembling and cleaning the wire transport mechanism, and replacing worn components such as gears and timing belts. Inspecting the lubrication of the machine tool guide rails, cleaning the old grease, and applying new lubricating oil to ensure smooth guide rail movement.
- Annual Maintenance: Contact professional technicians to conduct overall performance testing on the equipment, including detecting the output parameters of the high-frequency power supply and the stability of the control system. Perform systematic maintenance and adjustment based on the test results.
- Long-Term Shutdown: If the equipment is out of use for a long time, remove the electrode wire, perform anti-rust treatment, apply anti-rust oil to the worktable surface, and cover the equipment with a dust cover.
Following the above maintenance process can effectively reduce the failure rate of high-speed wire-cut EDM equipment, extend its service life, and provide a solid guarantee for efficient and precise machining.
