Carbide end mills are expensive tools which are a necessity in the majority of successful industrial milling applications. Different cnc cutter serve different purposes – finishing, roughing, material-specific applications, and many more – and in order to protect your investment as well as get the most out of your equipment, it is important that you use them correctly. These guidelines will help you accomplish that, potentially saving you thousands.
In relation to selecting the right end mill to your project, two flute square end tools tend to be recommended. These mills are center cutting and created specifically for slotting, plunging, and contouring. The wide flute design is good 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 a number of styles, and the quantity of flutes can vary around 12. Multi-flute tools may have different purposes, and in order to protect your investment, it is crucial that you employ them appropriately. Probably the most common include:
Three flute styles. These end mills are a wonderful compromise involving the chip removal amount of a two flute and the effectiveness of carbide corner radius end mill with a lot more flutes. Just like the two flute option, it also provides a square end to obtain the ultimate surface finish.
Four flute styles. Four flute end mills are especially versatile in terms of milling in materials where chip packing isn’t a concern. These tools offer an increased core thickness that leads to improved size accuracy and less tool deflection. Additionally they offer minimal chip load.
Six flute styles. The robustness of the six flute option provides increased tool stability, allowing more cutting edges to stay engaged throughout the work material. The end result 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 produce a perfectly square corner, especially towards the bottom of your channel, a square end mill can be your best answer. A square end cutting feature can produce clean 90 degree angles in the bottom of your cut. Remember though, fewer flutes allow for better chip evacuation.
High helix carbide end mills – which can 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 often used in combination with aluminum and also other non-ferrous materials, mostly as a result of positive shearing action and also the extra really advanced for wear.
To obtain the maximum return on the investment and extend the life of your respective carbide end mills, a radius ground is an excellent solution. The weakest point by using an end mill is the sharp corner, so a ground radius on the tips prevents chipping.
The primary expense of tapered end mill may be high, especially for good performance and new designs. However, with proper things to consider for the sort of end mill that may are best for your personal application – in addition to proper set up – the price will likely be offset by better finishes, greater productivity, and higher production.
