AGIE MFD 3-87 18C4E1

Overview

AGIE MFD 3-87, serial trace code 18C4E1, is a pulse generator and gap monitoring control PCB for Agie wire EDM equipment. It belongs to the same MFD / EBD pulse control family, installed inside the EDM generator cabinet to regulate spark discharge and real-time gap condition feedback. It is widely supplied as exchange spare for Agie wire cut machine electrical cabinet overhaul and pulse control board replacement.

Features

AGIE MFD 3-87 18C4E1 receives cutting recipe commands from the machine CNC controller. It controls pulse on-time, pulse off-time and peak discharge current for rough cutting, skim cutting and finishing processes. Onboard sampling circuits continuously capture gap voltage and gap current signals to distinguish open gap, normal spark, sustained arc and short-circuit states. When dangerous arcing or short-circuit is detected, the board suppresses discharge pulses rapidly to prevent wire breakage and workpiece burning.

AGIE MFD 3-87 18C4E1 transmits gap status and fault signals back to the main machine controller. Onboard LED indicators display power status, pulse output activity and fault alarms for fast on-site inspection. Cutting parameters for different wire diameters, workpiece materials and surface finish requirements are downloaded from the CNC to tune the pulse profile. The PCB is engineered to withstand high-frequency switching noise inside the EDM generator enclosure.

Specs

AGIE MFD 3-87 18C4E1Brand: Agie (GF Machining Solutions) Model: MFD 3-87 Serial number: 18C4E1 Type: EDM pulse & spark gap control PCB Core functions: discharge pulse shaping, gap voltage/current sampling, arc and short-circuit protection Adjustable parameters: pulse on-time, pulse off-time, peak discharge current Feedback: real-time spark gap condition detection Compatible equipment: Agie wire electrical discharge machine Mounting: fitted inside EDM generator power cabinet Protection rating: IP20 This is not a servo drive, CNC CPU or power supply module; it is the spark control board for the EDM cutting power loop. AGIE MFD 3-87 18C4E1 is widely supplied as service replacement spare for EDM pulse control failure.

Principle

AGIE MFD 3-87 18C4E1 outputs controlled high-energy pulses across the gap between wire electrode and workpiece. The sampling circuit continuously reads gap electrical signatures. If sustained arcing or short circuit is identified, the board modifies pulse timing or temporarily stops discharge to clear the gap. Once the spark condition returns to normal, pulse output resumes automatically to maintain stable cutting speed and surface quality.

Applications

AGIE MFD 3-87 18C4E1 is deployed for precision mold, die and tool wire cutting workshops. It is selected for spare inventory and EDM generator cabinet retrofit projects for existing Agie wire EDM systems.
