Carbide end mills are costly tools which can be essential in the majority of successful industrial milling applications. Different carbide end mills serve different purposes – finishing, roughing, material-specific applications, and more – and to be able to protect your investment as well as get the most from your equipment, it is important that you make use of them correctly. These tips can help you accomplish that, potentially helping you save thousands.
In relation to choosing the right end mill for your project, two flute square end tools are often recommended. These mills are center cutting and specifically designed for slotting, plunging, and contouring. The wide flute design is ideal for chip evacuation, especially at higher feed rates with heavy peripheral cuts. Better yet – the square end will create a clean 90º angle when slotting.
Carbide end mills come in many different styles, and the number of flutes can vary as much as 12. Multi-flute tools could have different purposes, and in order to protect your investment, it is essential that you make use of them appropriately. Some of the most common include:
Three flute styles. These end mills are an excellent compromise involving the chip removal volume of a two flute and the potency of rough end mill with more flutes. Just like the two flute option, additionally, it supplies a square end to obtain the ultimate surface finish.
Four flute styles. Four flute end mills are especially versatile in relation to milling in materials where chip packing isn’t a problem. These tools come with an increased core thickness leading to improved size accuracy and fewer tool deflection. In addition they look after minimal chip load.
Six flute styles. The longevity of the six flute option provides increased tool stability, allowing more cutting edges to stay engaged inside the work material. The outcome is extended tool life and reduced chipping in the cutting edges.
Variable helix styles. This tapperedend minimizes deflection and reduces vibration. These characteristics ensures superior finish at high stock removal rates.
If you want to develop a perfectly square corner, especially at the bottom of a channel, a square end mill will be your best answer. A square end cutting feature can produce clean 90 degree angles at the end of the cut. Remember though, fewer flutes permit better chip evacuation.
High helix carbide end mills – which might also be known as high-spiral, shallow wedge, or high helix angle end mills – are a kind of high-performance cutter that is certainly designed specifically for soft materials.
High helix carbide end mills are usually combined with aluminum and other non-ferrous materials, mostly as a result of positive shearing action as well as the extra cutting edge for wear.
To get the maximum return on your investment and extend the lifespan of your respective carbide end mills, a radius ground is a great solution. The weakest point upon an end mill may be the sharp corner, so a ground radius around the tips will prevent chipping.
The primary value of aluminum end mill could be high, specifically for top rated and new designs. However, with proper things to consider for the type of end mill that can are best to your application – as well as proper put in place – the charge will be offset by better finishes, greater productivity, and better production.
