Carbide end mills are expensive tools that are an absolute necessity in the majority of successful industrial milling applications. Different cnc cutter serve different purposes – finishing, roughing, material-specific applications, and many others – and as a way to protect your investment and to get the most out of your equipment, it is crucial that you make use of them correctly. These pointers will help you just do that, potentially saving you thousands.
In terms of choosing the right end mill for your personal 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 perfect 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 number of flutes can vary approximately 12. Multi-flute tools may have different purposes, and in order to protect your investment, it is important that you make use of them appropriately. Many of the most common include:
Three flute styles. These end mills are a wonderful compromise in between the chip removal number of a two flute and the strength of rough end mill with a lot more flutes. Much 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 especially versatile in terms of milling in materials where chip packing isn’t an issue. These power tools provide an increased core thickness that leads to improved size accuracy and much less tool deflection. Additionally 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 keep engaged in the work material. The outcome is extended tool life and reduced chipping of 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 have to build a perfectly square corner, especially at the end 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 in the cut. Remember though, fewer flutes enable 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 kind of high-performance cutter which is specifically designed for soft materials.
High helix carbide end mills are often combined with aluminum and other non-ferrous materials, mostly as a result of positive shearing action and the extra really advanced for wear.
To obtain the maximum return on the investment and extend the life span of your respective carbide end mills, a radius ground is a wonderful solution. The weakest point on an end mill is definitely the sharp corner, so a ground radius on the tips can prevent chipping.
The primary cost of micro diameter end mill may be high, particularly for good performance and new designs. However, with proper considerations for the kind of end mill that will are best to your application – in addition to proper setup – the cost will probably be offset by better finishes, greater productivity, and better production.
