Long Interval Items | EDM Machine maintaining | Wire EDM Filters Suppliers Long interval items vary from bi-monthly to yearly.
Machine Filters: Replacement of the main water filters will be required and should be performed as needed (most machines will typically generate an alarm when the filters are depleted). Replacement intervals are purely dictated by the type of work, workpiece material and thickness, and applications being performed. Many machines also contain a safety filter for the AWT system that will need replacing periodically (six to 12 months). The filtration system on a wire EDM is fundamentally necessary because it controls the amount and size of particles/debris that can exist and be circulated through the flushing system during machining. If this debris is excessive and of a large particulate size, machining will be very unstable and inefficient.
De-ionization Resin: This is a special resin that is used to control the conductivity of the water within the machine. If the conductivity or resistivity of the water is not controlled and sustained at a certain level that the machine requires, machining will become very unstable, and final results will be inaccurate. The de-ionizing (DI) resin is replaced when needed (most machines will typically generate an alarm when the resin is depleted). There also is a conductivity/resistivity probe that requires cleaning to ensure proper level readings. 

Water Level: Over time, the water level in the machine reservoir will become low from evaporation and will need to be replenished. The quality of the incoming water (tap water is typically used) can affect the life of the DI-resin.
Belts, Rollers and Pulleys: Certain machine designs require periodic replacement of some belts, rubber rollers and pulleys. Replacement may be required due to physical wear of the component or from wear of replaceable bearings. It is very important that these items be maintained, checked and/or replaced by specific procedures and intervals suggested by your machine tool manufacturer. Failure to keep these items within operational specifications will result is part inaccuracies and machine downtime.
Wire Choppers: Some machines contain a wire chopping unit that cuts the used or spent wire into small pieces. Maintenance on this unit will include the sharpening or replacement of cutting blades and dies. The results of allowing these cutting edges to become excessively dull will lead to workpiece inaccuracies, excessive wire lines on the workpiece and machine downtime. Wire EDM Filters
Cabinet Filters: Some machine designs require the changing or cleaning of an air filter element. Such filters are commonly found on intake fans of the electrical/generator cabinets and water chiller units. These filters should be inspected, cleaned and replaced at regular intervals specified by the OEM. If these filters become excessively clogged, air flow will be restricted, which will lead to overheating and failure of the equipment.
Machine Seals: Due to specific seal designs, some seals and/or gaskets may require a yearly replacement to ensure proper machine operation. The seals/gaskets that typically require the most attention are the work tank door gasket and the lower arm tank seal plate. Proper maintenance and care of the lower arm sliding seal plate is especially important because as this seal wears and friction increases, machining accuracies also may be degraded.
Machine Floats: Most manufacturers recommend a yearly inspection and cleaning of machine operational and safety float switches. If these floats become excessively dirty, their operation may fail, resulting in damaged machine electrical components and water spillage.
Water Reservoir: The quality level of the water within the machine can become degraded over time and heavy sediments also can build up in the water holding tanks. Contaminants from cleaning agents also can change the pH levels of the water, all of which can affect the performance of the machine. Most wire EDM manufacturers recommend that the water be drained and the water reservoir cleaned yearly. Insufficiently monitoring and maintaining the reservoir system may result in excessive machine corrosion, sedimentary buildup and machine component/pump failure. Wire EDM Filters
Machine Lubrication: Check with your machine’s OEM on recommended intervals and access points for machine lubrication. The most common items that require attention are the ball screws and linear guide way systems. Be sure to use the proper lubricants that are specified by the OEM. Improper lubrication of the machine will lead to workpiece inaccuracies and the eventual replacement of costly machine mechanical components. Wire EDM Filters
