Greenleaf Corporation today announced XSYTIN®-360, a new line of high-performance solid ceramic end mills, to the global market. XSYTIN®-360 end mills combine Greenleaf’s phase-toughened XSYTIN®-1 substrate with a unique cutting geometry that offers ten times higher productivity and tremendous cost savings. The strength of the material allows the user to apply chip loads similar to solid carbide end mills with higher speeds common to ceramic machining. These new ceramic end mills provide customers with significant increases in productivity over current solid carbide or ceramic products.
Greenleaf’s XSYTIN®-1 material, introduced in 2016, was engineered to machine a wider variety of materials than any other ceramic in the industry. The structure of this phase-toughened ceramic exhibits high wear resistance and outstanding thermal shock resistance, which makes the XSYTIN®-360 end mills highly predictable, very versatile, high- performance products.
XSYTIN®-360 end mills have shown the highest material removal rates and resulted in increased productivity on a wide range of materials. These end mills have proven to be extremely effective when machining a variety of different materials including high-temperature alloys, 3D-printed sintered high-temperature alloys, hardened steels, ductile cast irons, and compacted graphite iron (CGI). In hardened steels specifically, the tool life of XSYTIN®-360 end mills has proven to be equal to high-performance carbide end mills when run at high-end speeds (11,460 RPM), while also removing over 73 cubic inches (over 1200 cubic cm) of material.
“I am extremely excited about the introduction of XSYTIN®-360 and the performance advantages these end mills offer to our customers. As the world leader in ceramic innovation, we worked hard to make sure that our entry into the end mill market was one of true innovation, differentiation, and value,” says Bernie McConnell, Executive Vice President - Commercial at Greenleaf Corporation. “We believe we have achieved our goal! The high-performance solid round tool market opens up a whole new opportunity for Greenleaf to expand our presence and market share in new and existing customers.”
Unique features and benefits of XSYTIN®-360 end mills include:
-
Our unique flute design minimizes cutting forces, which reduces vibrations and optimizes tool life
-
XSYTIN®-1 ceramic material provides ultra-high strength and wear resistance at extreme feed rates
-
Four-flute design allows for maximum material removal in slotting, pocketing, and profiling applications
-
Overall length of the end mills provides the option for regrind capabilities
-
A very broad application range means numerous machining centers are capable of running these end mills
-
Extremely versatile end mills with twice the feed rate capability and a much broader speed range
-
Increased material removal rates (MRR) of 100% over carbide solutions
Ideally suited for machining materials in the aerospace, automotive, die & mold, and power generation industries, XSYTIN®-360 inch and metric end mills are available now.
Related Glossary Terms
- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- cast irons
cast irons
Cast ferrous alloys containing carbon in excess of solubility in austenite that exists in the alloy at the eutectic temperature. Cast irons include gray cast iron, white cast iron, malleable cast iron and ductile, or nodular, cast iron. The word “cast” is often left out.
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- compacted graphite iron
compacted graphite iron
Cast iron having a graphite shape intermediate between the flake form typical of gray cast iron and the spherical form of fully spherulitic ductile cast iron. Also known as CG iron, CGI or vermicular iron, it is produced in a manner similar to that of ductile cast iron but using a technique that inhibits the formation of fully spherulitic graphite nodules.
- ductile cast irons
ductile cast irons
Ferrous alloys in which graphite is present as tiny balls or spherulites. The spheroidal graphite structure is produced by adding one or more elements to the molten metal, among which magnesium and cerium are commercially important. Approximate composition of ductile cast irons is: 3.0 to 4.0 percent carbon, 0.1 to 1.0 percent manganese, 1.8 to 2.8 percent silicon, 0.1 percent (maximum) phosphorus and 0.03 percent (maximum) sulfur. Typical ductile cast iron grades are D-4018, D-4512, D-5506 and D-7003 by definition of the Society of Automotive Engineers; 60-40-18, 65-45-12, 80-55-06, 100-70-03 and 120-90-02 by definition of the American Society for Testing and Materials. Also known as nodular cast irons.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
- profiling
profiling
Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
- slotting
slotting
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
- wear resistance
wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
