In wire EDM many people focus on programs, parameters and the machining itself. Yet one of the most important factors affecting work quality is maintenance. Robofil is a very precise machine working in demanding conditions — high energy, water, microscopic tolerances. Without regular inspection, problems develop gradually and often unnoticed. Initially everything "works", but quality drops, time increases and costs accumulate.
⚙️ Why Does Maintenance Matter So Much?
In Robofil everything is interconnected: wire, guidance, water and parameters. If one element begins to deviate from normal, the whole process loses stability. Effects of neglected maintenance: more frequent wire breaks, poorer surface finish, unstable operation and greater consumable use.
💧 Water System — The Most Important Element to Control
The dielectric is responsible for process stability, cooling and material removal. If something is wrong, the process begins to "drift", errors appear and quality drops. Check regularly:
- Electrical conductivity — directly affects discharge stability
- Temperature — too high or variable destabilises the process
- Cleanliness — contaminated water causes process problems
🔧 Filters — Often Neglected, but Critical
Worn filters cause deterioration of water quality, process instability and greater risk of problems. This is one of the simplest elements to check — and one of the most frequently neglected. Regular filter changes are one of the cheapest investments in quality maintenance.
🔩 Wire Guidance System
The wire must move smoothly and without resistance. If the guides are worn, the wire begins to vibrate, dimensional accuracy deteriorates and break risk increases. This element strongly affects quality — especially on precision parts requiring ±0.002 mm tolerances.
⚡ Contacts and Working Elements
Over time the contacts, guide elements and parts in contact with the wire wear out. Effects: worse conductivity, unstable sparking and quality drop. These are not spectacular failures — but they have a very real impact on production output.
🔴 Symptoms of Neglected Maintenance
- Wire breaks more frequently than usual
- Surface quality deteriorates without any settings change
- Longer machining time with the same parameters
- Unstable operation, process fluctuations
📅 How Often Should You Maintain?
Maintenance is not a one-off action — it is a systematic approach. The best results come from regular inspection, quick reaction to deviations and systematic checking of all key systems. This approach prevents problems rather than fixing them — which ultimately greatly reduces production costs and eliminates unplanned stoppages.
