`HIGH PERFORMANCE THIN·FILM COATINGS FOR CUTTING TOOLS & WEAR PARTS
`
`

`
`HIGH PERFORMANCE
`
`THIN-FILM COATINGS
`
`FOR CUTTING TOOLS & WEAR PARTS
`The importance of advanced coatings in ·
`achieving dramatic gains in cutting tool
`and wear part performance cannot be
`overstated. Properly applied, coatings
`improve many tool and part characteristics.
`They increase surface hardness, lower the
`friction coefficient and thermal conductivity,
`and provide a chemically inert surface.
`Performance benefits include: significantly
`increased tool and part life, reduced friction
`and heat buildup, and high resistance to
`edge buildup, galling and fissure
`propagation. Applying the right coating can increase tool and
`part productivity from 100% to over 1000%!
`
`TECHNOLOGICAL LEADER. As a cutting tool manufacturer,
`GUHRING offers a level of technical expertise without equal
`in the industry. GUHRING was the first to introduce TiN
`coating (Titanium Nitride) to cutting tools in 1980 and has
`remained a global leader in developing and applying new
`coating technology to improve both cutting tool and wear
`part performance. Today, GUHRING offers a full range of
`high performance thin-film coatings to meet customers'
`diverse needs, including:
`• TiN (Titanium Nitride),
`• TiAIN (Titanium Aluminum Nitride),
`• TiCN (Titanium Carbonitride),
`• FIREX® (special TiN-TiAIN multilayer hard coating),
`• AlliN (Aluminum Titanium Nitride),
`• MolyGiide® (Molybdenum Disulfide-based soft coating),
`and other advanced hard, soft and combined coatings.
`
`Each application presents different performance challenges,
`and GUHRING's advanced coating selection provides
`application-specific solutions,
`delivering higher hardness,
`increased heat and shock
`resistance, and greater lubricity as
`required. By effectively matching
`the right high performance coating
`to each application, GUHRING
`Coating Services maximizes tool
`and wear part productivity and
`cost effectiveness- providing
`absolute value for money.
`
`./ LONGER TOOL & WEAR PART LIFE
`./ FASTER OPERATING SPEEDS & FEEDS
`./ SIGNIFICANTLY INCREASED PRODUCTIVITY
`
`STATE-OF-THE-ART EQUIPMENT. Coatings are only as
`good as the process used to apply them. Advanced
`equipment, special training and experience are vital.
`GUHRING utilizes both state-of-the-art cathodic arc and
`reactive ion coating systems to deliver superior coating
`adhesion, uniform thickness and structure, and batch-to(cid:173)
`batch reproducibility.
`
`Advanced climate control
`systems maintain optimum
`facility air temperature,
`humidity and pressure,
`while removing dust and
`other airborne impurities.
`A custom-designed, fully
`automated ultrasonic
`cleaning system maximizes tool and part pre-coating
`cleanliness, while precision stereo dynascopes enhance
`both pre- and post-coating visual inspection. Coating
`adhesion and thickness are closely monitored utilizing
`calotest and other advanced measuring equipment.
`
`UNIQUE APPROACH. What takes place in the coating
`chamber is widely considered the most critical step in the
`coating process. However, if tools and parts are not properly
`prepared, coating quality can be severely compromised. At
`GUHRING, we take the time to prepare each job properly.
`First, we clean each tool and part thoroughly in our special
`five-stage ultrasonic cleaning system. Second, we sort
`each job by tool and part size, geometry, and material type
`to promote optimum coating uniformity and thickness.
`Properly cleaned and sorted, the tools and parts are then
`placed in the coating chamber. We monitor the coating
`process closely to ensure that neither the structural
`integrity nor geometry of the tools
`and parts is altered.
`
`In sum, GUHRING's approach to
`coating combines high technology
`with personal attention to detail
`'
`resulting in a level of coating
`quality and service few can match.

`

`
`TiN • S-coat
`Titanium Nitride
`The gold S-coat is an excellent. all-around , cost-effective high performance coating which increases tool and part surface hardness to over
`80 Rc, greater than tungsten carbide. As such , S-coated tools and parts last up to five times longer than uncoated tools and parts, and can
`be run at more aggressive speeds and feeds. Amoog TiN coating providers, no competitor has been able to match the performance profile of
`Guhring's S-coat.
`
`TiAI N • A-coat
`Titanium Aluminum Nitride
`The black-violet A-coat is recommended when extra hard ness and heat resistance are required , as when machining abrasive materials such as
`cast iron and high silicon-content aluminum alloys. During cutting, an oxide (AI203) layer forms over the A-coat, providing extremely high heat
`resistance. A-coat also performs equally well in high thermal stress conditions, such as high speed turning, near-d ry and dry machining, and
`deep and small diameter holemaking where cutting fluids have difficulty penetrating.
`
`AI TiN
`Aluminum Titanium Nitride
`Now, for application in materials 40 Rc and higher, there's a new Guhring coating- AITiN! This dark gray coating is unique in its ability to
`provide the high heat resistance, high hardness and high friction coefficient needed to dramatically improve cutting tool performan ce in
`hardened materials. AITiN is ideal for high speed, high velocity drilling, milling and turning of hard and/or abrasive materials, plus dry
`machining applications.
