Carbide end mills are costly tools which are absolutely essential in the majority of successful industrial milling applications. Different cnc cutter 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 essential that you utilize them correctly. These pointers may help you accomplish that, potentially saving you thousands.
In relation to selecting the right end mill for your project, two flute square end tools are frequently recommended. These mills are center cutting and specifically made for slotting, plunging, and contouring. The wide flute design is great for chip evacuation, especially at higher feed rates with heavy peripheral cuts. Even better – the square end will produce a clean 90º angle when slotting.
Carbide end mills come in a variety of styles, and the number of flutes can vary up to 12. Multi-flute tools can have different purposes, and so that you can protect your investment, it is crucial that you utilize them appropriately. Among the most common include:
Three flute styles. These end mills are a great compromise in between the chip removal amount of a two flute and the effectiveness of carbide corner radius end mill with increased flutes. Much like the two flute option, it also gives a square end to get the ultimate surface finish.
Four flute styles. Four flute end mills are specifically versatile with regards to milling in materials where chip packing isn’t a concern. These tools come with an increased core thickness that leads to improved size accuracy and much less tool deflection. In addition they offer minimal chip load.
Six flute styles. The durability of the six flute option provides increased tool stability, allowing more cutting edges to keep engaged in the work material. The end 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 develop a perfectly square corner, especially at the end of the channel, a square end mill is the best solution. A square end cutting feature can produce clean 90 degree angles in the bottom of the cut. Remember though, fewer flutes provide for better chip evacuation.
High helix carbide end mills – that might even be called high-spiral, shallow wedge, or high helix angle end mills – are a variety of high-performance cutter that is specifically made for soft materials.
High helix carbide end mills are usually combined with aluminum as well as other non-ferrous materials, mostly because of the positive shearing action and also the extra leading edge for wear.
To have the maximum return on the investment and extend the life of the carbide end mills, a radius ground is an excellent solution. The weakest point with an end mill is the sharp corner, so a ground radius about the tips can prevent chipping.
The original price of tapered end mill might be high, specifically top rated and new designs. However, with proper things to consider for the type of end mill that can perform best for your application – along with proper put in place – the fee will probably be offset by better finishes, greater productivity, and higher production.
