Types of mini EDM machines

Some mini EDM machines are also suitable for these jobs, such as sinker EDM, wire-cut EDM (the most common type), and hole-drilling EDM. Others may be specialized for something else or be versatile enough to do additional jobs. They can also be classified into different types depending upon the nature of the work they can conduct.

• Sinker EDM Mini Machine: This type of machine uses shaped electrodes for cutting. The electrode is submerged in a dielectric fluid, and the workpiece is further machined to the same shape as the electrode. This machine is sometimes known as the plunge or cavity EDM. They work best for hard materials that cannot be easily machined by other means. Another feature is that they may be ideal for making complex inner cavities and geometries, improving production efficiency, and shortening lead times.
• Wire EDM Mini Machine: Also known as Wire Cut EDM, this is the more popular type made up of a brass or copper wire that cuts through the material while being guided by a computer system. This machine usually costs less than mini sinker machines because its technology is more widely available and understood. These machines usually cut metal into complex or simple geometric shapes and profiles, including inner features, holes, and details, that may be difficult to achieve by other means.
• Hole Drilling Mini EDM Machine: This machine is specialized for drilling holes into small sizes (up to 0.3 mm). This type of machine allows making blind holes without counterboring or plugging holes.
• Combination mini EDM machine: Some mini EDMs can perform various activities. These versatile machines are usually found in the small or midsize category as there is not enough space for all larger models in the industry.
• Fast Cut mini EDM machine: Another type of machine usually does fast cuts. These machines are famous for their acceleration ratio, usually up to ten times more than an average machine. They are familiar to those with limited time and a longer runway than average.

Specifications and Maintenance

The working range and table size are crucial specifications for a mini EDM machine because they influence the dimensions of the components that can be effectively machined with it. Another important specification is the power of the machine, usually expressed in kilowatts (kW). Power impacts factors like the speed of metal removal and the range of workpieces that can be processed. Additionally, the machine's EDM electrode holder or collet is designed to suit various electrode shapes and sizes.

• Power Supply: The power supply unit for the spark generation in the EDM process is a critical specification. It determines the type of EDM (die-sinking, wire-cut, or hole-drilling) and can be either conventional AC or DC power; DC power is preferred in many cases.

• The flushing system for removing debris from the work area during machining is also an important specification. Some machines use low-pressure coolant pumps, while others may provide options for high-pressure flush pumps.

To ensure the machine operates at its best, routine maintenance checklists can be prepared to focus on critical areas and parts of a CNC mini EDM machine. This may include a weekly focus on essential machine areas. Operators and maintenance technicians can follow a straightforward checklist highlighting specific parts of the machine to be inspected, cleaned, lubricated, or calibrated. Instead of tedious overhauls, this efficient approach saves time and ensures that only the high-impact areas are prioritized for care and maintenance, extending the life and performance of the CNC mini EDM machine.
