CGK·RZ·02 Graphite Electrode Body Flexible Auto Processing Line
Five CNC Operations in One Coordinated Line
The CGK·RZ·02 is built for carbon plants producing graphite electrode bodies — the current-carrying columns that thread into nipples to form the full electrode column in an electric arc furnace.
A graphite electrode body is the large-diameter column that carries the furnace current and threads into a nipple at each end. Its bore, outer diameter, thread profile and end-face flatness determine whether the electrode column runs straight and carries current without hot spots at the joints. Where plants run these operations on isolated machines with crane transfers between stations, the CGK·RZ·02 removes every manual hand-off and holds tolerance across the full sequence, because each station starts from a datum the previous station has already established.

Five machining capabilities plus an automatic conveyor turn a row of standalone machines into one coordinated electrode-body line.
Double-End Boring & Scraping
Bores the centre hole and scrapes both end faces in one clamping, establishing the common datum every downstream station works from.
Multi-Tool External Turning
Strips the oxidised skin and brings the full body length to finished diameter, holding cylindricity across long graphite columns.
Double Thread Combing
Cuts the internal threads at both ends that mate with nipples, holding pitch error and thread-geometry accuracy on every body.
End-Face Finishing
Finishes the end faces that seat against the nipple shoulder, controlling flatness and perpendicularity to protect joint sealing.
Automatic Overhead Conveyor
An overhead automatic conveyor transfers each electrode between stations, removing crane handling and floor-crew bottlenecks.
Optional Inline Measurement
Electronic weighing, specific-resistance measurement, hole-bottom-circle machining and data printing can be added to match your quality protocol.
Why Choose the CGK·RZ·02
Against isolated electrode-body machines linked by crane handling, the CGK·RZ·02 wins on datum integrity, thread precision and lifecycle cost.
Eliminates Re-Clamping Error
The line passes each body through boring, turning and threading in one datum chain, so re-clamping drift never compounds between stations.
International-Advanced Thread Precision
Single-thread pitch error ≤0.015 mm, cumulative pitch error ≤0.025 / 150 mm and thread geometry within ±20′ — precision that controls joint resistance.
Unmanned Operation
Full CNC on every station plus Siemens PLC whole-line linkage lets the line run shifts with minimal floor presence.
Flexible Type I / II Configuration
Type I covers Φ300–Φ600 mm and Type II covers Φ450–Φ960 mm bodies — switch by calling a part program, not by retooling.
Lower Lifecycle Cost
One automated line replaces isolated machines, cranes and manual inspection benches — cutting footprint, labour and cross-shift variability.
Remote Monitoring Ready
Optional upper-computer and remote-access architecture let supervisors track status, alarms and tool trends from the control room or offsite.
