The TIG Point Tandem grinder (WIG Spitz) is a premium equipment for cutting and grinding tungsten electrodes. The grinder uses a dry grinding processes. For grinding of the electrodes a cup wheel is used with a diameter of 150mm. The unique position of the tungsten against the grinding wheel allows a perfect longitudinal grind on the tungstens.  The grinding in the longitudinal direction has a uniform arc result. Without adjustment to the unit tungsten electrodes 1 to 6.4 mm in diameter and of varying length can be ground in succession.

The unit is sold as a TIG point grinder which allows only grinding of the tungstens or a tandem TIG point grinder which has a grinding wheel and a diamond cutting wheel to cut tungstens to length. Both models of this grinder are CSA inspected.

Cronitex Tungsten Grinder is a quality equipment for grinding tungstens. The unique rotating element allows the rotation of the tungsten while it is being ground. The simple yet ergonomic design allows the operator to roate the tungsten ensuring logitudinal grinds.

A precision device for use in the workshop, at a tool crib or on-the-job-assembly site. More efficiency, more safety and service life for automatic TIG welding systems, orbital or linear.

Why Longitudinal Grinding is important?

Owing to the method of manufacture of tungsten electrodes, the molecular structure of the grain runs in a longitudinal direction. Lateral grinding has a detrimental effect on the stability and formation of the tip caused by its notching effect. It is a fact that electrons flow at a greater density on the surface of an electrical conductor. The TIG or tungsten electrode is the crucial electrical carrier in a welding or cutting process. If electrodes are ground laterally (also polished laterally), the electrical energy skips the grinding channels. The arc starts previous to the tip, is widely leaked and jitters. The tungsten electrode also gets heated excessively and its thorium trails away earlier, considerably reducing its life.

By grinding longitudinally, the electrodes are carried steadily to the outermost tip of the tungsten electrode. The arc is narrow and bell-shaped. The high-frequency-ignition is carried out precisely in a straight line. The tungsten electrode is subjected to an appreciably lower thermal load and therefore has a very long service life.
