Characteristics of the Degen Hiking Machine in Germany

The Degen machine is built around the idea that the operator should not stand at the machine between cuts. Its tool replacement device swaps electrodes or cutting tools without the operator opening the work envelope. That cuts non-cutting time down and removes a common source of scrapped parts, since a hand-loaded tool is a hand-loaded error.

Material loading and unloading are handled the same way. The machine picks up the workpiece, seats it against the fixture, and unloads it when the cycle ends. Wire training, the step where the wire is threaded through the guides and re-tensioned after a break, also runs without intervention. Anyone who has threaded a 0.25 mm wire by hand at 02:00 knows why this matters.

These functions are not exotic on their own. What stands out is that they are integrated on one platform rather than added as separate options. Fewer interfaces means fewer failure points and less floor space lost to peripheral units.

Wire handling drives the accuracy of any wire EDM process. Wire tension that drifts produces taper error and a wandering kerf. The Degen platform monitors tension through the cut and adjusts feed rate to hold it. For a 0.25 mm wire cutting 40 mm thick tool steel, that is the difference between a straight wall and a wall you have to grind later.

Automatic wire training also changes how a shop schedules work. A break that takes 15 minutes to clear by hand takes under two minutes when the machine re-threads itself. On a job with 60 starts, that adds up to hours recovered per week.

The trade-off is that automatic wire systems are fussier about wire quality. Inconsistent wire diameter or poor spool winding will trip the sensors. If your wire supplier is cheap, budget for more manual intervention than the spec sheet suggests.

The machine uses a proprietary tool and kit structure. Guides, nozzles, and fixtures are designed to seat with a defined repeatability, so a changeover does not require re-dialing the machine from scratch. That is useful on high-mix work where the machine may see three different part families in a day.

The structure is also meant to be portable. Kit components can be moved between machines of the same generation, which helps a shop that runs several units and wants common spares rather than a shelf of one-off parts.

One caution: proprietary tooling ties you to one supply chain. Before buying, ask how long the tooling family will be supported and what the lead time is on a replacement guide set. A machine that is down waiting for a guide is not saving you any cycle time.

This class of machine earns its cost on parts that repeat. Stamping dies, extrusion dies, and punch tooling are the classic fit: hardened steel, tight corner radii, and enough volume that unattended hours pay back the capital. Medical and aerospace shops also use it for small, high-value components where a single scrapped part is expensive.

It is a poor fit for one-off work with simple geometry. If a part needs one straight cut and ships tomorrow, a manual machine does the job for a fraction of the cost. The automation sits idle and you never recover the investment.

Material matters too. The platform handles hardened tool steels, carbide, and superalloys well. It is not the right process for soft aluminium prototypes where milling is faster and cheaper. Pick the process by geometry and hardness first, then by volume.

  Poor fitSimple one-off cuts, soft materials, prototypes better served by milling.

Ask for a live cycle on your own part geometry, not a demo coupon. Bring a part with a tight corner and a deep cut, and watch the wire training run. That tells you more than any brochure.

Confirm the spares and service path. How fast can a guide set or a power module reach your shop? What is the training plan for your operators? A machine that takes three weeks to service will sit idle more than the spec sheet implies.

Finally, match the machine to your real mix. If 80 percent of your work is repeat tooling, the automation pays. If 80 percent is one-off, it does not. That ratio, not the feature list, decides the purchase.
