The Tool Room Challenge
Setting up or expanding a tool room is a significant investment. Choose the wrong machine and you'll face years of compromises — limited capability, excessive maintenance, or simply the wrong technology for your parts.
This guide walks through the decision framework that Berlin's application engineers use with customers.
Step 1: Define Your Primary Application
What parts will this machine make 80% of the time?
- Punches and dies → Wire Cut EDM
- Mould cavities → Sinker EDM + Milling
- General precision parts → Milling + Lathe
- Surface finishing → Surface Grinding
- Start holes for wire EDM → EDM Drill
- Heavy material removal → Milling
Step 2: Workpiece Size and Weight
Match your machine's working envelope to your largest typical workpiece (not your largest ever workpiece — that's what outsourcing is for).
Key specs to check:
- Table travel (X × Y × Z)
- Maximum workpiece weight
- Table size (must physically fit the part + fixtures)
Berlin's Wire EDM range covers 320×250mm (FDK-7725) up to 1000×800mm (N Series Hyper 800).
Step 3: Accuracy Requirements
Be honest about what accuracy you actually need:
| Requirement | Suitable Technology |
|---|---|
| ± 0.1 mm | General milling, lathe |
| ± 0.05 mm | Precision milling, CNC lathe |
| ± 0.02 mm | Wire EDM (standard) |
| ± 0.01 mm | Wire EDM (precision grade) |
| ± 0.005 mm | Wire EDM (high-end, controlled environment) |
Step 4: Production Volume
- Prototype / single piece → Versatility matters most
- Small batch (10–100) → Setup time and repeatability matter
- Production (100+) → Speed, automation and unmanned operation matter
High-volume production justifies machines with auto wire threading, auto pallet systems, and 24/7 unmanned capability.
Step 5: Budget Reality
Consider total cost of ownership, not just purchase price:
- Machine cost
- Installation and foundation
- Training
- Tooling and consumables (wire, filters, dielectric)
- Maintenance and AMC
- Power consumption
- Floor space
A cheaper machine with higher consumable costs and more downtime can cost more over 5 years than a premium machine with better reliability.
