CHMER | Taiwan's Leading EDM Machine Manufacturer

Company Overview

Precision EDM Machines

Trusted by Manufacturers Worldwide

Founded in 1975 and headquartered in Taichung, Taiwan, CHMER is Taiwan's largest EDM manufacturer and one of the world's leading EDM brands.

Built on the core values of integrity, innovation, and customer satisfaction, CHMER designs and manufactures its core components entirely in-house—including controllers, linear motors, and automatic wire threading systems—ensuring full command over quality and performance.

With sales and service coverage across 55+ countries and 90+ service points globally, CHMER delivers reliable precision machining solutions for mold making, aerospace, automotive, and medical industries.

Wire Cut EDM

CHMER's wire-cut EDM series is built for mold makers and precision parts manufacturers, where cutting accuracy and long-term repeatability are non-negotiable.

Dual-Balanced Linear Motor
CHMER's dual-balanced linear motor runs at near-ambient temperature without any cooling system, and fully neutralizes magnetic attraction to preserve structural integrity through years of continuous operation.

ISC Intelligent Step-Difference Control
As workpiece thickness changes during cutting, ISC monitors the discharge waveform in real time and adjusts energy output. Compared to operation without ISC, cutting speed improves by up to 35%, and step-difference error is reduced by up to 6 µm.

AWT with EC Tension Control
CHMER's proprietary EC tension control delivers a near-100% automatic wire threading success rate across standard and submerged conditions. Threading time is reduced by over 20%, while power consumption drops by 18% and cutting consumables wear is 100% extended — lowering costs in high-volume production environments.

Die Sinker EDM

CHMER's Die Sinker EDM is built for precision cavity and mold applications where surface finish, electrode wear, and complex geometry are the deciding factors in machine selection.

Linear Motor Drive
CHMER's Die Sinker EDM applies linear motor drive to the X, Y, and Z-axis, replacing the conventional ball-screw and servo motor combination. Traverse speed reaches 18–21 m/min versus 2–5 m/min on ball-screw systems, with zero positioning lag. Also in comparative testing, the linear motor drive reduces processing time by 35% and corner consumption by 25% against the AC servo motor.

Patented Air Balance Spindle with Internal Gas Recovery
The Z-axis linear motor drive combines with an air balance cylinder. The air source is recovered through a patented internal circulation system, maintaining consistent chip removal performance in deep groove and rib applications.

E Code — Proprietary 3-Axis Programming
CHMER's E Code replaces G and M code programming with application-specific codes that execute 3-axis simultaneous machining directly. Operators select from dedicated codes for orbiting, contouring, spiral threading, internal and external profiling, and rollaway mold geometry, reducing setup time and programming errors on complex cavity work.

Drilling EDM

Chmer's drilling EDM is built for applications requiring fast, precise hole drilling through hardened steel, carbide, and difficult-to-machine alloys — including turbine cooling holes, wire EDM start holes, and fluid dynamics components.

UX1 Linear Motors
All movements are driven by CHMER's proprietary UX1 linear motors, delivering zero friction, zero backlash, and vibration-free response with no energy transmission loss.

Dual Detection: BTD + BOD
Breakthrough Detection (BTD) halts the electrode at a preset depth. Breakout Detection (BOD) stops the electrode the moment it breaks through the material, preventing over-drilling and back-wall strikes inside internal cavities or passageways. Operate simultaneously, making it suitable for blind hole, through hole, and internal channel applications without manual monitoring.

Inverter-Controlled Spindle and High-Pressure Water
Flush pressure automatically increases as hole depth increases, maintaining consistent chip evacuation regardless of depth. Spindle inverter control also reduces electrode wear and suppresses back strikes after breakthrough.
