Julian was fantastic, he patiently walked me through the steps for diagnosing issues with our syringe pump. We found it was a simple belt that was broken and he sent out a replacement part the same day. read more
Micro ball end mills or "micro ball nose end mills" are single end, general purpose mills used for making full radiused grooves, generating large corner radii, or contour profile milling.The term "general purpose" means that the mills are manufactured with a 30 helix angle, and are center cutting.Mini ball end cutting tools are generally used on CNC machines for a variety of milling operations like milling molds, profiling, and engraving. Available in diameter sizes .005" - .120".
A ball end milling cutter is also known as a "ball nose mill". The end of this tool is ground with a full radius equal to half of the tool diameter, and the edges are center cutting. They can be single end or double end and they can be made from solid carbide or various compositions of high speed steel. They can be general purpose or high perfomance geometries. They can be used used for milling a large corner radius, grooving with a full radius, and contour or profile milling. The smaller diameters can be used for engraving. They are available in a wide variety of standard sizes and lengths.

A carbide endmill (end mill) is a type of milling cutter, a cutting tool used in industrial milling applications. Endmills can cut in all directions, although some cannot cut axially. Endmills are used in milling applications such as side milling, profiling, face milling, and plunging. Carbide endmills are used in machining steels, cast iron, high temperature alloys, and non-ferrous materials. Carbide endmills allow faster machining and leave better finishes on metal parts. Carbide endmills can withstand higher temperatures than high speed steel tools.
Cemented carbides are composed of a metal matrix composite where carbide particles act as the aggregate and a metallic binder serves as the matrix. The process of combining the carbide particles with the binder is referred to as sintering. During this process, the binder eventually will be entering the liquid stage and carbide grains (much higher melting point) remain in the solid stage. The binder is embedding/cementing the carbide grains and thereby creates the metal matrix composite with its distinct material properties. The naturally ductile metal binder serves to offset the characteristic brittle behavior of the carbide ceramic, thus raising its toughness and durability. Such parameters of carbide can be changed significantly within the carbide manufacturer's sphere of influence, primarily determined by grain size, cobalt content, dotation, and carbon content.
Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and endmills.
To increase the life of carbide endmills (end mills), they are sometimes coated. Four such coatings are TiN (titanium nitride), TiC (titanium carbide), Ti(C)N (titanium carbide-nitride), and TiAlN (titanium aluminum nitride). Most coatings generally increase a tool's hardness and/or lubricity. A coating allows the cutting edge of a tool to cleanly pass through the material without having the material gall or stick to it. The coating also helps to decrease the temperature associated with the cutting process and increase the life of the tool. The coating is usually deposited via thermal CVD and, for certain applications, with the mechanical PVD method at lower temperatures.
