Applying a coating to a tool allows the user to substantially increase speeds and feeds while minimizing tool wear.  So that you may choose the best coating for your particular application, Melin provides any one of our 3 standard coatings (TiN, TiCN, and AlTiN) for the same coated price.  

Melin coats nearly all tools in house using a state of the art coating center in our Cleveland facility. Controlling the coating process allows us to:

• maintain excellent coated tool inventories
• preserve low costs associated with coating tools
• reduce lead times to apply coatings to uncoated tools

Most common sizes are stocked with coatings.  Uncoated tools can usually be coated in less than one week.

To order standard coated tools, simply add TiN, TiCN, or AlTiN after the tool name or change the 1 in the first digit of the EDP number to 2 for TiN, 4 for TiCN, or 5 for AlTiN. 

Other coatings include nACo (read complete details in this Cutting Tool Engineering article), ZrN, CVD, and PVD.

Standard coatings: Titanium Nitride (TiN) Titanium Carbonitride (TiCN) Aluminum Titanium Nitride (AlTiN)  Other coatings available: nACo - Aluminium Titanium Nitride + Silicon Nitride CVD Diamond Coating (Dia) Zirconium Nitride (ZrN) Black Oxide
TiN  -  Titanium Nitride Hardness - 2900HV Thermal Stability - 950F The ideal coating for a wide range of applications, materials, and cutting conditions where tool life and higher feeds and speeds are operating objectives.  The high lubricity of TiN facilitates chip flow, prevents build up and reduces cutting forces and temperature.  TiN reduces wear and improves chip formation to extend tool life.  TiN is a good choice for for the machining of iron-based materials, molding of plastics, and for components requiring resistance to abrasive and adhesive wear.
TiCN  -  Titanium Carbonitride Hardness - 4000HV Thermal Stability - 750F An exceptional high hardness and low coefficient of friction coating which provides excellent wear resistance.  TiCN performs well cutting alloy steels, stainless steels, and in high speed cutting where moderate temperatures are generated at the cutting edge.  Provides an excellent surface quality on machined components.  Also, excellent in applications which require high feed and speed rates.
AlTiN  -  Aluminum Titanium Nitride Hardness - 4500HV Thermal Stability - 1450F AlTiN has very similar features to TiAlN.  It is ideal for high temperature cutting operations in the same materials as TiAlN and has the same oxidation effect.  AlTiN has a higher aluminum content which makes it much harder and smoother than TiAlN.  It is ideal for smaller depths of cut and excels in high speed and dry machining applications and when machining hardened steel.

* In July 2002, Melin discontinued the use of TiAlN as a standard coating.  We highly recommend the much harder AlTiN coating for TiAlN applications (AlTiN: 4500HV vs. TiAlN: 2600HV).
