CNC end mills Full-time Job

There are many different factors that go into the objects you can create with a CNC mill, but the biggest contributor is going to be your CNC end mills. At the most basic level, end mills are like drill bits but instead of only drilling vertically, they can also cut horizontally and have several form factors to get the cleanest cut for specific materials. Some are used only for plastics to keep from heating too much, some are designed to keep wood from chipping or tearing out, and some are designed for ultra-fine detail work. ;

There are a lot of strange beasts out there in the cutting tool world and a lot of physics that are not obvious. For example, many machinists will know that more flutes mean more productivity, but that certain materials, like aluminum, require fewer flutes–usually two or three. If that's the case, when would it ever make sense to use 1 flute end mill? Is there a time when the least number of flutes possible is a good idea?

FINISHING END MILLS-2 FLUTE

Finishing End Mills are used in metalworking applications for removing material or burrs from a workpiece and leaving behind a smooth finish. 2 Flute End Mills ;are used for center cutting (plunge cut) operation and when chip removal in slots and grooves is a problem. A wide range of coatings such as Titanium Nitride (TiN), Titanium Carbon Nitride (TiCN), Titanium Aluminum Nitride (TiAlN or AlTiN), and Diamond finishes permit maximum performance and value for a particular application or material. Both standard and metric shank and cutting diameters are available.

Uncoated High Helix Single End Mills from TTC Production. These HP series of single-end mills are exclusively designed to work on aluminum workpieces. TTC's HP series are available in two-flute, spiral designs and come in regular, long, and extra-long lengths. The tool is made from high-speed steel and the center cutting makes it suitable for peripheral, ramping, helical, plunging, and slotting operations. The high helix angle wraps around the tool faster and provides excellent chip evacuation at high speeds. ;

3 Flute End Mills - Carbide, Cobalt & HSS

Three flute end mills ;are used for higher feed rates than two flute end mills and are often used in aluminum machining. ; They are commonly used in grooving operations where the chip is crowded. ; They are also used in non-ferrous milling applications where high feed rates are used. ; Three flute mills tend to reduce vibrations during the cutting operation. ;

PCB Corn Teeth End Mill

PCB Corn Teeth End Mill is suitable for printed circuit board (PCB), high-density fiberboard (HDF), super hardwood, carbon fiber, fiberglass, HDF composite board, bakelite plate, epoxy board, shell, or powder materials.

The Bits

Now when it comes to the actual engraving bits, there are an incredible amount of different types. However, in this article, we'll simplify things and go down to two basic ones - metal and Plexi.

Drill bits ;are grouped into two categories: roller cone and drag (Fig. 11). Roller cone bits are of two types: milled-tooth and insert. They are designed to drill rocks of various types and strengths.

Woodworking router bits come in a variety of sizes. To ensure safety and the best possible results from your routing, you must adjust the speed of the router to suit the diameter of the router bit. The general rule is the larger the bit, the slower the maximum allowable router speed.
