CNC Knife Cutting Tools


CNC knife cutting machines most commonly use a “drag knife” tool - a blade simply pushed by the machine. The knife may be anything from a boxcutter blade in a holder to a hardened alloy of a customengineered shape. Drag knives are easy to use and easy to replace, but may have trouble with very tough or abrasive materials. If the material is very thick, the cut material will be in contact with the sides of the blade and produce increased friction. This friction will put stress on the blade and also tend to push the material out of place.


CNC Knife Cutting Tools


An “oscillating tangential knife” may be used for tough or thick materials. This kind of blade cuts part way into the material, retracts upwards, and then returns quickly. By doing this, strain on the material is repeatedly released instead of building up around the blade, reducing the chances of tearing the material or breaking the blade. Oscillating tangential knives may just be drag knives mounted to move up and down, or may be more specialized for downward penetration, like a chisel.


A rotary blade, often called a “creasing wheel”, may be used for cutting abrasive or hard materials, or for making indentations in any material. A rotary tool turns freely as it is pushed, and has one continuous edge. Very abrasive materials will quickly dull the pushed edge of a drag or oscillating knife, but a rotary edge doesn’t drag through the material. In many cases a hardened (titanium nitride) oscillating blade is tough enough and can cut quickly, but a wheel blade can be the ideal solution especially for thin, abrasive composites. The downside of a rotary blade tool is that the curve of the blade can push into the material in more than just one point, so where a drag knife might cut at just one point as it cuts a curve, a rotary blade might scrape the surface on the convex side of the cut.


Drag knives are the most susceptible to dulling by abrasion, and a duller blade will experience more stress as it is dragged, making it more likely to break. For this reason, drag knives are often cheap and easily replaced rather than re-sharpened. Oscillating tangential knives are more likely to fail in fatigue due to vibration than the other tools. Rotary blades tend to be much harder and tougher than what they’re cutting, and experience less friction, and so are the least likely to fail. A tool which is not sharp enough adds stress to the region it is cutting, which can result in jagged edges as the material bunches and releases, deformations like stretches or tears around the cut, or even shoving the material out of its fixturing.

Universal Routing Tool


Universal Routing Tool


At the heart of the Universal Routing Tool is a 300 W router spindle which operates at up to 80,000 rpm, depending on material and application. In combination with the 3 mm bits STYLECNC offers, this routing/engraving tool delivers solid performance in a wide range of applications. Aside from processing softer materials, the tool can also process more challenging substrates in multiple passes.


In a few quick steps, the Universal Routing Tool can be converted from routing to engraving. In Engraving mode, the height of the tool relative to the material surface can be precisely adjusted with a micrometer screw. This ensures precision engraving, with consistent line widths and depths.


The airflow from the dust-extraction effectively cools both the router bit and the spindle, which significantly increases their longevity.


Universal Routing Tool Advantages


1. Routing and engraving with one tool.

2. Consistent, precise control of routing depth.

3. 300 watt router spindle with up to 80.000 RPM.

4. Stepless adjustable speeds.

Universal Drawing Tool


Universal Drawing Tool


Universal Drawing Tool is a cost-effective tool for precision marking/plotting on materials such as fabric, leather, rubber or Teflon. Common applications include plotting assembly markers, line symbols and text.


Universal Drawing Tool is very cost-effective since it accommodates widely available, standard drawing/plotting tools such as felt-tip and ballpoint pen cartridges available in various line widths.


Universal Drawing Tool Advantages


Drawing/plotting of guidelines, line symbols, text, etc.


Raster Braille Tool


Raster Braille Tool


The raster method has emerged as the preferred process for creating tactile/Braille signage for the blind and visually impaired. The process is quite simple: the router drills holes into the substrate, and the Raster Braille Tool automatically inserts the spheres. Because the spheres fit perfectly into the holes, the resulting Braille is resistant to wear and exceedingly durable.  


The Raster Braille Tool is perfectly coordinated with Zünd’s routing/engraving tools, which makes the entire process very efficient.


Raster Braille Tool Advantages


Secure fit of spheres in substrate.


Ink Jet Tool


Ink Jet Tool
