Cutting tool and wear parts substrates have benefited from enormous engineering advances over recent decades. Thin film coatings, when properly applied, improve tool and part characteristics and functionality. They increase surface hardness, lower the friction coefficient and thermal conductivity and provide a chemically inert surface. As a cutting tool manufacturer, Guhring offers a level of coating expertise without equal in the industry. Guhring was the first to introduce TiN coating to tools in 1980 and has remained the global leader in developing and applying new coating technology. Today, Guhring offers a full range of high performance PVD (Physical Vapor Deposition) coatings to meet customers’ diverse needs.

The optimized relationship of hardness and residual compressive stress of the titanium aluminum nitride coating TiAlN increases the stability of the cutting edges of machining tools. Its outstanding thermal and chemical resistance permit dry cutting and improvements in performance of highly stressed components. The high hardness of this mono-layer coating gives outstanding protection against abrasive wear and erosion.

The 0.0313" (0.8mm) shell cutter features a 3-flute design with a light chip-breaker finish-grind that effectively, and accurately cuts away both natural and laminated shell.  A member of the UltraBit family, the shell cutter diameter is ground to within +/-0.0005"  (0.0127mm) insuring zero-glue-line inlay cutting and minimum material wastage.

This comprehensive guide unfolds the definition, basic components, diverse types, and significant role that metal microstructure plays in engineering.

nano-FIREX® coating is a PVD hard coating which combines the heat and wear resistance of TiAlN with the universal applicability of TiN coating, all in one multi-layer structure. The TiAlN in the structure increases the oxidation temperature (the point in which the coating combines with oxygen in the atmosphere and begins to break down), or operating temperature, to 1,470° F. This is much higher than TiCN, which has an oxidation temperature of 840° F. Another property of TiAlN coating is that at elevated temperatures the coating will have a surface hardness of approximately 3,300 (HV 0.05), which is more than 3 times the hardness of TiCN. The multi-layering approach that combines TiAlN with TiN provides increased resistance to shock which can crack standard mono or single layer coatings. Guhring's nano-FIREX® has the same TiAlN/TiN components as standard FIREX, but in a new micro-layered structure. nano-FIREX has significantly more micro-layers in the same overall thickness than the original FIREX. This imparts superior wear characteristics, especially in applications where shock resitance is a major consideration.

When drilling in stainless steels the cutting edges of cutting tools are subjected to extreme stresses. A mechanically wear resistant coating

The most common value for d is 0.800 in. (industry standard). However, with the advent of mechanically etching printed circuit boards in the mid 1970s, a new standard was implemented for the special purpose tools developed for this application.

The titanium carbon nitride coating TiCN is distinguished by extreme hardness and high toughness. Coated tools are outstandingly wear-resistant. The low coefficient of friction protects against cold-welding. TiCN coating is not recommended for high heat applications due to the relatively low maximum operating temperature. Threading and some milling applications are a natural fit.

This is especially helpful with micro-tools where "touching-off" on some reference surface to calibrate the tool height can damage or break the tip of the tool. Rings also find widespread use in inlay pocket cutting where relatively large diameter cutters are used to "hog out" basic shapes, followed by much smaller diameter finishing bits that clean up the edges, sharpen the corners and add fine detail to the finished part.

Today, only machines made by LPKF and T-Tech adhere to this special standard. Systems from AccurateCNC, MITS, Sun and EverPrecision are compatible with the original industry standard depth of 0.800 in.

The only 2-flute member of the UltraBit family, these 0.0313" (0.8mm) bits have been tuned for cutting antler, fossil ivory, horn and tusk.  The flute capacity has been increased to accommodate a wide range of moisture/oil content. The diameter is ground to within +/-0.0005"  (0.0127mm) insuring zero-glue-line inlay cutting. The best all-around 1/32" cutter that we make, this bit has become the general-purpose tool of choice for many cuemakers and luthiers for cutting rosewoods and other "gummy" materials.

Our 2-flute stub end-mills were designed specifically for cutting non-ferrous metals like copper, silver and gold.  The 4-flute tools are made for cutting brass, steel, sterling silver and stainless steel. They are characterized by low aspect ratio flute geometries insuring low deflection and long bit life at relatively high feed-rates. The precise radial relief reduces burr formation and chattering resulting in smoother, more uniform cutting.

Thanks to a nano-layer structure as well as reduced aluminum content Endurum was specifically adapted for the drilling of low-alloyed

The titanium nitride coating TiN was introduced by Guhring in 1980 and it remains a proven and versatile standard coating. It provides effective protection against abrasive and adhesive wear. It is often applied for its decorative effect or as a wear indicator.

The flutes of our ball-nose end-mills wrap around the tips of the tools with the identical geometry on the sides and across the ball.  This insures that the cutting properties (speed, feeds, smoothness, chip load) are the same at all points along the cut.

Over the years, we have found that certain materials place extraordinary demands on tool geometry.  This is especially true of shell, ivory, ebony and the rosewood family of hardwoods.  Their moisture content, oiliness, density and abrasiveness require that flute-shape, flute-volume, and helix angle be precisely tuned to achieve accurate cutting and acceptable tool life.

Ever since we started making tools for cuemakers and luthiers, jewelers have been using some of our smaller end-mills and engraving tools to carve butter board and blue and green jeweler's wax. In response to the persistent demand for longer flute lengths on the smaller diameter mills, we have redesigned some of our existing tools and developed a few new ones. These high-aspect ratio micro-bits are part of our new DeepReach family of mold and sign making tools.

Guhring's newest PVD applied nano coating is nano-A™. nano-A is a multi-layer coating that combines TiAlN and AlTiN coatings in a micro-layer structure that is harder and more wear resistant. Whereas TiAlN coating has an oxidation temperature of approximately 1,470° F, AlTiN coating has an oxidation temperature of approximately 1,650° F, and the hardness is increased to 3,800 (HV 0.05). The micro-layer structure of nano-A makes this a better choice for applications where AlTiN would normally be used, such as hard milling steel and materials over 45 HRC; but test results have also shown that nano-A is frequently the best coating for high speed drilling and milling of all grades of stainless steels including 300 and 400 series grades.

Guhring’s coatings research department has developed a new nano multi-layer coating for nickel base materials and hardened materials that require high surface hardness coatings. Called Signum, this TiAlSiN (titanium aluminum silicon nitride) based coating is designed to yield similar performance to diamondlike coatings without the restrictions on the host base material substrate. With a hardness value of 5,500 (HV 0.05), Signum stands up to the most abrasive applications. The oxidation, or maximum useful operating temperature, is over 2,192°F, which is similar to high temperature coatings such as FIREX® or TiAlN. Test results in drilling inconel have shown a 35% increase in tool life compared to a comparable TiAlN based multi-layer coating using the same operating parameters. Similar results were found when machining cast iron and hardened steels over 52HRc. No other coating can provide this high hardness property while still retaining the toughness required in drilling and milling applications.

Tempered Gold phenolic backing material is the perfect fixturing substrate for mounting delicate materials to be machined for inlay components. With a high degree of chemical resistance and excellent adhesion to common glues and adhesives (including hide glue and cyanoacrylates), Gold phenolic is compatible with the mounting requirements of virtually every material used by luthiers, jewelers, and pool cuemakers. The composition of the phenolic also acts to cool the tip of the drills and end-mills, extending tool life and eliminating thermal breakdown of the fixturing adhesive.

Developed to improve cutting tool performance in titanium alloys, this coating has also been proven to reduce built up edges when machining aluminum, and has had positive results in some nickel alloys. The Zirconium Nitride (ZrN) in Zenit is chemically inert in titanium, whereas coatings with a Ti-based element tend to want to bond with the workpiece material, causing a large increase in friction and reducing tool life.

FIREX® is a multi-layer coating that provides the shock resistance of TiCN coating with the heat resistance of TiAlN coating. This universal application coating was initially developed for dry machining but has since become the most popular heat resistant coating. FIREX is a multi-layer combination of TiN and TiAlN coatings which provides thermal stability and wear resistance in both high temperature and applications that do not generate excessive heat.

The shank side of the ring (top side in the picture to the right) is accurately positioned (d ±0.004 in.) relative to the tip of the tool. If the shank-side of the ring is pressed against the collet when the tool is loaded, the tip of the bit will be a known distance (d) from the face of the collet. Knowing this distance, the programmer can plunge the tool, confident that the depth of cut will be as expected and will remain the same no matter how many times the tool is changed. If all of the tools in the programmer's magazine have been fitted with depth setting rings, an automatic tool changer can load and unload tools with the tip of each one the same distance from the face of the collet.
