Products Description
The CM300 Mirror Finish Die Sinker EDM Machine is designed for precision mold cavity machining and applications requiring excellent surface finish with low electrode wear.
Equipped with a 600 × 400 mm worktable, 300 mm X-axis travel, 210 mm Y-axis travel, and 270 mm Z-axis travel, the CM300 is especially suitable for small and medium-sized precision molds, inserts, electrodes and complex cavities.
With a best surface roughness of Ra < 0.1 μm, maximum machining current of 50A, and electrode wear below 0.1%, the CM300 provides a reliable solution for precision EDM finishing and mirror-surface mold processing.
Key Features
Mirror Finish EDM Performance
The CM300 is developed for applications where surface quality is an important requirement.
The machine can achieve:
- Best surface roughness: Ra < 0.1 μm
- Low electrode consumption: < 0.1%
- Maximum working current: 50A
- Maximum productivity: ≥500 mm³/min
This allows the machine to balance machining efficiency with fine surface quality.
Compact Precision Machining Range
The CM300 provides:
- X-axis travel: 300 mm
- Y-axis travel: 210 mm
- Z-axis travel: 270 mm
Its compact working range makes it suitable for precision mold components and smaller cavity applications where stable fine machining is more important than extra-large travel.
High-Rigidity Structure
The CM300 is designed with high rigidity to support stable machining during both roughing and finishing operations.
A rigid machine structure helps reduce vibration and deformation during long EDM cycles, supporting more consistent dimensional accuracy and surface quality.
Low Electrode Wear
Electrode wear can directly affect cavity accuracy and machining cost.
With electrode consumption controlled below 0.1%, the CM300 is suitable for precision mold applications where electrode profile retention is important.
High Machining Efficiency
The machine provides a maximum productivity of ≥500 mm³/min, allowing it to perform both cavity material removal and fine finishing within one EDM platform.
