Applications that need a lot of metal removal can be through the use of an aggressive cutting depth and a medium feed to successfully processed, or using a light cutting depth and super aggressive feed. Both achieve high metal removal rates, but also provide different types of machine tools.
Older, more powerful machines can respond well to a button that runs under heavy, deep cuts, usually allowing only moderate feed. Update, portable machine is built for speed, allow the button tool in high speed machining “mode, to provide good metal removal rate and low cutting depth and feed rate very fast.
The cutting force can also be controlled with a button cutter. When working at a heavy cutting depth, a button cutter will produce a more radial cutting force (horizontal direction from the tool’s contact direction). However, by reducing the cutting depth – such as high speed or high feed processing – the cutting force is more axial (up to the spindle), allowing stronger metal cutting and longer tools.
DPA’s rhine-carb insertion line provides an outstanding value for the performance of button cutting tools. Our new RPMH button insertion is characterized by thicker carbon, providing better intensity and thermal absorption. The cutting edge of the technical pressure provides a positive geometric shape for low force cutting and has the ability to handle the maximum feeding speed. There are three different geometric shapes to choose from. DPA’s rhine-carb “T” insertion is the most robust, providing the strongest advantage for an attack or high-shock application. “N” cutting edges allow aggressive feed, but with higher positive edges to create less pressure and heat than “T”. The DPA’s most important cutting edge is “D”, which provides the ultimate high shear cut for low cutting force, low heat and optimum performance of stainless steel and high temperature alloys.
This is just one example of the daily challenges of most mechanical stores – how best to rough it before half-finished or finished machining.
