High cutting quality

Extensive hole performance

The Voortman Xtensive Hole Performance is developed to optimize holes and inner contours with high definition plasma cutting, resulting in laser like cutting results. To achieve this, Voortman further optimized the Hypertherm® True Hole™ and Kjellberg® Contour Cut range by creating a perfect match between the technology and dynamic movement of the Voortman V304.

Next to this, the Xtensive Hole Performance is applied on small to medium sized slot holes and square inner contours. Damage by lead-ins and lead-outs is eliminated, creating nothing but a perfect slot hole or square inner contour.

The Xtensive Hole Performance is also developed for cutting holes in aluminum and stainless steel creating far better results than ever possible before. For aluminum it is now possible to cut a good quality hole with a diameter which is at least 1,5 x the thickness. For stainless steel it is possible to cut a good quality hole which has a diameter of at least two times the thickness. Voortman Xtensive Hole Performance is standard integrated in the VACAM operating software and will be standard selected when cutting small holes.

 

Accurate and dynamic movement

Voortman took the next step in cutting accuracy with the transmission systems of the Voortman V304. Transmission systems with almost no play in arc minutes ensure nothing but a smooth cutting surface in the X and Y-axis. A milled S49 rail ensures a stable and equal movement which results in very accurate cutting quality. The X rails are equipped with a helical rack and pinion transmission with reduced backlash. This ensures an increased accuracy and more dynamic movement compared to a straight rack and pinion. The dynamics are also fully optimized and accelerations/decelerations are smooth and leveled. Vibrations are minimized creating nothing else than an equal cutting surface.

 

Eliminate taper caused by plasma

The I-cut correction fully eliminates taper caused by the plasma process. Angular deviation or taper in the cutting surface is a typical attribute of plasma cutting. Voortman now introduced the I-cut correction which counteracts the taper with a bevel correction. Taper in the cutting surface is fully eliminated. Arc lag usually also occurs when cutting holes. With the I-cut correction taper with holes is even fully eliminated. Hole tolerances can even match tolerances of holes created by drilling.

 

Prevent slag formation during piercing

Slag formation during piercing is a common problem when cutting with plasma. The blast from piercing the material creates a volcanic effect which blows molten metal over the material. To prevent this, Voortman developed the ‘Dross Inhibitor’. The Dross inhibitor sprays oil at the piercing area just before piercing, this allows for the slag to bounce of the oil layer and in this way it has no chance of attaching to the plate. The Dross Inhibitor not only significantly reduces the post processing time but it will also increase the cutting quality.
