Carbide end mills are pricey tools which are absolutely essential in most successful industrial milling applications. Different cnc cutter serve different purposes – finishing, roughing, material-specific applications, and others – and to be able to protect your investment and also to get the best from your equipment, it is essential that you use them correctly. These tips can assist you just do that, potentially saving you thousands.
In terms of choosing the right end mill for the project, two flute square end tools are usually recommended. These mills are center cutting and created specifically for slotting, plunging, and contouring. The wide flute design is great for chip evacuation, especially at higher feed rates with heavy peripheral cuts. Much better – the square end will generate a clean 90º angle when slotting.
Carbide end mills come in a number of styles, and the volume of flutes can vary up to 12. Multi-flute tools could have different purposes, and in order to protect your investment, it is important that you utilize them appropriately. Among the most common include:
Three flute styles. These end mills are an excellent compromise between your chip removal amount of a two flute and the potency of carbide corner radius end mill with more flutes. Just like the two flute option, additionally, it gives a square end to get the ultimate surface finish.
Four flute styles. Four flute end mills are specifically versatile in relation to milling in materials where chip packing isn’t a concern. 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 reliability of the six flute option provides increased tool stability, allowing more cutting edges to remain engaged in the work material. The final result is extended tool life and reduced chipping of your cutting edges.
Variable helix styles. This tapperedend minimizes deflection and reduces vibration. These characteristics ensures superior finish at high stock removal rates.
If you wish to produce a perfectly square corner, especially at the end of a channel, a square end mill is the best answer. A square end cutting feature can produce clean 90 degree angles in the bottom of the cut. Remember though, fewer flutes permit better chip evacuation.
High helix carbide end mills – that might additionally be called high-spiral, shallow wedge, or high helix angle end mills – are a form of high-performance cutter which is designed specifically for soft materials.
High helix carbide end mills are frequently used in combination with aluminum along with other non-ferrous materials, mostly as a result of positive shearing action along with the extra leading edge for wear.
To find the maximum return on the investment and extend the lifestyle of the carbide end mills, a radius ground is a wonderful solution. The weakest point by using an end mill will be the sharp corner, so a ground radius about the tips prevents chipping.
The first expense of tapered end mill might be high, particularly for high end and new designs. However, with proper things to consider for the type of end mill which will perform best for your personal application – as well as proper setup – the fee is going to be offset by better finishes, greater productivity, and better production.
