About

Mitsubishi EDM filters are essential components in Mitsubishi Electrical Discharge Machining (EDM) systems, designed to maintain the performance and longevity of the equipment by preventing contaminants from entering critical parts such as the electrical systems, cooling systems, and fluid systems. Regular maintenance of these filters is necessary to ensure optimal performance, reduce downtime, and increase the lifespan of the machine.

Types of Mitsubishi EDM Filters:

1. Coolant Filters:

   • Function: Coolant filters are used to remove metal chips, debris, and other contaminants from the dielectric fluid (coolant) used in the EDM process. Clean coolant is critical to prevent clogging, maintain good electrical conductivity, and ensure consistent machining performance.
   • Common Types:
     • Cartridge filters: Typically used for fine filtration of coolant to remove small particles.
     • Bag filters: Larger filtration units used to collect and filter larger debris.
   • Maintenance: Coolant filters need to be cleaned or replaced regularly, depending on the amount of debris and contamination in the coolant.

2. Air Filters:

   • Function: These filters prevent dust and particulate matter from entering sensitive areas of the EDM machine, such as the control panel or motor areas, where they could cause malfunctions or wear. They ensure clean airflow to the machine's ventilation systems, preventing overheating.
   • Maintenance: Regular cleaning or replacement of air filters is essential, especially in dusty environments, to maintain optimal airflow and prevent the buildup of heat within the machine.

3. Oil Filters:

   • Function: Used to filter the lubricating oil or hydraulic fluid in the EDM system, oil filters remove contaminants that could affect the operation of components such as servo motors, hydraulic pumps, and other moving parts. Clean oil ensures that the machine operates smoothly and efficiently without causing wear or internal damage.
   • Maintenance: Oil filters should be replaced periodically, depending on the system's usage. Contaminated oil can lead to increased wear, reduced efficiency, and potential failure of the hydraulic or lubrication systems.

4. Hydraulic Filters:

   • Function: Hydraulic filters in EDM machines remove dirt, metal particles, and other contaminants from the hydraulic system. This is particularly important for maintaining smooth operation and avoiding damage to the hydraulic components like the pumps and actuators that drive the movement of the EDM machine's mechanical parts.
   • Maintenance: Hydraulic filters should be inspected and replaced regularly to ensure that the hydraulic system remains clean and free from contaminants that could cause blockages or wear.

5. Vacuum Filters:

   • Function: Vacuum filters are used in systems that require vacuum pumps for chip collection, coolant circulation, or workpiece clamping. These filters help maintain the vacuum pressure and ensure that the system remains efficient.
   • Maintenance: Regular cleaning or replacement of vacuum filters ensures consistent vacuum pressure and prevents contamination from affecting the machine's functionality.

Superior Filtration Efficiency

Engineered for exceptional performance, Mitsubishi EDM Filters achieve up to 99.9% filtration efficiency, reliably capturing particles as small as 5 m. This level of filtration ensures smooth machine operation and high-quality surface finishes, contributing significantly to precision manufacturing applications and maintenance of EDM equipment.


Durable Construction for Long Service Life

These cartridge filters are constructed from high-grade paper and fiber, providing robust durability and a smooth surface finish. Withstanding operating temperatures up to 80C and pressures up to 8 Bar, each filter is designed to last up to 500 machine hours, minimizing downtime and supporting continuous machining needs.


Versatility and Wide Compatibility

Mitsubishi EDM Filters fit a broad range of Mitsubishi EDM models, making them a reliable choice for diverse manufacturing environments. Their 178 mm outer diameter, 88 mm inner diameter, and 295 mm height enable integration into various machines while ensuring effective particle retention and minimal risk of clogging.
