Tech CNC Solutions

• Made from Superior brass
• Outstanding straightness and strength
• Special sizes available only an order.

We stock a wide variety of EDM electrodes in brass, copper in both single-hole tube and multi-channel (coreless) styles, with diameters ranging from 0.3mm to 3.00mm.

Performance Characteristics
 Capable of machining apertures from 0.3
mm to 3.0 mm, with a maximum depth-to-
diameter ratio exceeding 300:1.
 Processing speed ranges from 5 to 40 mm
per minute. Features a 300 mm servo stroke
and supports extra-long electrode tubes,
saving up to 15% on electrode tube
consumption.
 Suitable for processing a wide range of
conductive materials, including stainless
steel, quenched steel, cemented carbide,
copper, and aluminum.
 Capable of direct penetration from inclined
planes and uneven surfaces.
 Servo lifting mechanism uses double linear
guide rails and electric lifting, ensuring high
processing accuracy and speed.
 The spindle features a dual-speed control
mode, enabling faster retraction and real-
time tracking of machining time, ensuring
efficient and stable processing, particularly
with fine electrodes.

A chuck’s ability to hold an electrode with stability forms the basis of an EDM drilling apparatus. A chuck lacking precision only compounds defects in its electrode and guide, and does not wear down uniformly, reducing its lifespan. Keyless chucks have a much faster setup time than keyed chucks, increasing efficiency.
