Tungsten Electrode Grinder

CORMAK CORMAK OE4.0

CORMAK OE4.0 TUNGSTEN ELECTRODE GRINDER – PRECISE TIG SHARPENING 1–4MM

The CORMAK OE4.0 tungsten electrode grinder is a professional device designed for welding shops and industrial workshops, enabling fast, precise and repeatable preparation of TIG electrodes with diameters of 1–4mm. Thanks to its compact, solid construction and adjustable rotational speed, it ensures welding arc stability and the highest weld quality.
Main advantages of the CORMAK OE4.0 grinder

Versatile operation: one device for angle sharpening, end grinding and cutting the electrode to length.
Precise sharpening angles: 15°, 18°, 22.5°, 30° ensuring repeatable results and a stable welding arc.
Rotational speed adjustment: adaptation to the electrode diameter ensures process control and minimises the risk of overheating.
Compact and mobile construction: easy to carry, ideal for workshops and service work.
Low noise level and safety: fully compliant with EU standards, equipped with guards and occupational safety micro-switches.
Complete consumables set: spare motor brushes included, increasing reliability and continuity of operation.

Construction and technology of the device

The CORMAK OE4.0 grinder has been designed for professional preparation of tungsten electrodes. A solid spindle bearing and precisely made housing construction minimise vibrations during operation. The 750W motor with rotational speed adjustment (up to 11,000rpm) allows the sharpening process to be adapted to the electrode diameter, ensuring repeatable results. The grinding disc cooling system and ergonomic electrode mounting guarantee safety and device durability.
Precision and work efficiency

Thanks to adjustable sharpening angles and the end grinding function, the CORMAK OE4.0 enables tungsten electrodes for TIG welding to be prepared in a repeatable and efficient way. Each electrode is sharpened according to the required specification, which directly translates into arc stability, reduced spatter and savings in welding material. The electrode cutting function allows the electrode length to be quickly adapted to the requirements of the welding station.
Application of the tungsten electrode grinder

The CORMAK OE4.0 device is used in:

TIG welding, both AC and DC, in industrial and production plants,
welding workshops, service departments and repair points,
industrial installations requiring high precision and repeatability of welds,
production processes where electrode preparation time and quality are crucial.
