EDM machine maintenance is a process that should be carried out at certain intervals and with certain rules to prevent big problems during the process, and avoid wasting time and parts. Maintenance is done to maintain the highest EDM processing speed, accuracy, surface tolerance, and provide high machine performance.

The purpose of our maintenance service is to plan routine fault preventive maintenance checks, train operators on maintenance procedures and, if necessary, perform maintenance.


The following describes maintenance requirements for EDM machinery. In order to avoid wasting time and parts of our customers, we plan all these treatments to the finest detail.


If machinery doesn't clean continuously, surface smoothness rate and machine performance decrease.

  • Contamination of the lower arm and head causes O-ring wear, leakage, and sensitivity problems. This cleaning should be done every 500 hours, and it takes about 15 minutes.
  • The conductivity sensor measures current transport levels of water between the two probes. If the conductivity sensor is dirty, the level is read lower. A higher water level than normal results in excessive rust, oxidation and cobalt erosion. This cleaning takes about 10 minutes and should be done every 300 hours.
  • The automatic wire threader enables wires to automatically process parts. It needs to be cleaned every 300 hours every 45 minutes to increase high performance.


Another component of preventive maintenance is to periodically check all machine components to ensure they are in proper working order. These components are wires, wire transport system, rollers, bearings, and flushing containers.

  • Wires are one of the components that causes the most loss of speed in EDM machines. It is important that these wires are fed to the system at right speed.
  • All cylinders and bearings must be inspected for correct operation and low wear. Bad bearings generate vibration and cause streaks on the workpiece surface. At the same time, worn grooves can cause wire curl.
  • Chipped, cracked or broken containers cause water to escape to sides, which reduces the cutting speed.
