Wire EDM and Sinker EDM in Union City with Systomatic

Some shapes cannot be cut with a spinning tool. A sharp inside corner, a very narrow slot, or a feature in hardened steel may be better made with electrical discharge machining, usually shortened to EDM. Systomatic Inc is a Union City shop listed here for sinker EDM, wire EDM, EDM hole drilling, true 5-axis contour machining and CNC lathe work. This page explains how EDM works and how to prepare a request for wire EDM in Union City.

What EDM does

EDM removes metal with a series of tiny electrical sparks between an electrode and the part, while both sit in a bath of fluid. No cutting tool touches the work, so there is almost no cutting force. That makes EDM useful for thin, delicate shapes and for very hard metals that are hard to cut with normal tools. The part must conduct electricity, so EDM is used on metals, not plastics.

Wire EDM

In wire EDM, a thin wire moves through the part like a very precise saw, following a programmed path. It is used to cut profiles, slots and punch and die shapes, and to cut parts from plate. It can create sharp inside corners that a round milling cutter cannot reach, since the wire is very thin. Typical wire EDM work includes tooling parts, gears and intricate cut outs.

Sinker EDM

Sinker EDM, also called ram EDM, uses a shaped electrode that is pressed toward the part and slowly erodes a cavity in its mirror image. It is a way to make pockets, ribs and cavities that cannot be milled, such as deep narrow slots or shapes with sharp corners. Mold makers often rely on it.

EDM hole drilling

EDM hole drilling uses a thin electrode to burn small holes, including very small holes and holes that start at an angle on a hard surface. The listing names it as a separate service, so describe your hole size, depth and material when you ask.

True 5-axis contour machining

The listing names true 5-axis contour machining. Five-axis machines can move the cutter around curved shapes in a smooth path. This suits sculpted surfaces and complex parts, and sometimes means fewer setups.

CNC lathe work

CNC lathes turn round parts such as shafts, pins and bushings. If your project needs a turned part plus an EDM feature, mention it in the same request.

When to choose EDM

• Sharp inside corners or narrow slots
• Hardened metals
• Delicate shapes that would flex under a cutter
• Complex cut outs in plate

For simple shapes in soft metals, regular milling is often cheaper and faster. A shop can tell you which process fits best.

What to include in your RFQ

• Drawing or 3D model with revision
• Material and hardness, if hardened
• Thickness of the part for wire work
• Tolerances and surface finish needs
• Quantity and reorders
• Delivery date

Surface and finish

EDM leaves a surface with a slightly textured look. If a smoother finish matters, say so in the request.

Why choose a nearby Union City shop

Union City is close to Fremont, Hayward and the South Bay, so a buyer working across those cities can reach it easily to talk about a tricky feature.

Planning for stock and fixtures

For wire EDM, the shop needs a starting hole or a clear edge to begin the cut, and the part has to be held steady in the machine. Tell the shop if material has already been hardened or if you plan to heat treat afterward, because hardening can move a part and the order of steps affects the result. Plate thickness also changes the cut time, so list it in your request along with the number of parts.
