PVD Coating

PVD Coating

We have exclusive tie ups & best economical prices with Major Component PVD coating companies, we always advice our clients to get the tools coated to enhance the life of cutters and also extend the feasibility of further grindings. 2 to 4 microns of PVD Coating helps the tools to strengthen its cutting ability, with feed and speed to cut, coating helps for smooth cutting and also gives extended life before the sharpness diminishes.

There are different types of coatings on gear cutters to dramatically extend the life of your tool. Offering the latest in high performance PVD coatings for most industrial applications including: Titanium Nitride (TiN), Titanium Carbonitride (TiCN), Titanium Aluminum Nitride (TiALN), ALCRONA Pro(MOST RECOMMENDED) as per client requirement.

It increases the tools life to more than 2 to 3 times, reduce the tool inventory, reduce machine downtime and increase shop efficiency.

1. Titanium Nitride (TiN)

) Coating is bright gold in colour with a surface hardness of 81 Rc and a 0.4 coefficient of friction. TiN has very good corrosion resistance, heat transmission and excellent wear resistance with a wide range of materials, including iron-based materials, hardened steels, and stainless steels. Forming operations can expect a decrease in galling and welding of a work piece material with a corresponding improvement in surface finish of the formed part. Increased tool life can run 3 to 8 times greater with increased feeds and speeds (finished parts per hour). Loner tool life and greater feeds and speeds depend upon the application, coolant, and other conditions. Hardness: 2800 HV; Coating Thickness: 2-4 microns; Thermal Stability: 550°s Celsius or 1000°s Fahrenheit.

2. Titanium Carbonitride(TiCN)

Coating is medium gray or bronze in colour with a hardness reaching 90 Rc and a 0.3 coefficient of friction. TiCN Coating has up to 750°s Fahrenheit thermal stability. TiCN offers improved wear resistance to abrasive, adhesive, or difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, copper, inconel, and titanium alloys. As in TiN, feeds and speeds can be increased and tool life can improve by as much as 800 percent depending on the application, coolant and other conditions. Hardness: 3000 HV; Coating Thickness: 2-4 microns. Thermal Stability: 400°s Celsius or 750°s Fahrenheit.

3. Titanium Aluminum Nitride(TiAIN)

Coating is dark purple/black in colour with a surface hardness in the upper 80 Rc range with a coefficient of friction, which is less than Titanium Nitride (TiN). TiAIN Coating is a high performance coating, which excels at machining abrasive and difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, and nickel alloys. TiAIN's improved ductility makes it an excellent choice for interrupted cutting operations. Its superior oxidation resistance provides unparalleled performance in high temperature machining. TiAIN does not exhibit edge brittleness and can be used for interrupted cuts without chipping. TiAIN Coating should be targeted at applications that generate the highest heat level at the tools cutting edge. Hardness: 2800 HV; Coating Thickness: 2-4 microns; Thermal Stability: 750°s Celsius or 1350°s Fahrenheit..

4. ALCRONA PRO

Coating is dark black in colour with a surface hardness in the upper 80 Rc range with a coefficient of friction, which is less than Titanium Nitride (TiN). ALRCONA PRO Coating is a high-performance coating, which excels in machining abrasive and difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, and nickel alloys. Its superior oxidation resistance provides unparalleled performance in high temperature machining. ALCRONA PRO Coating does not exhibit edge brittleness and is often recommended where the mass production components have to be produced. Hardness: 2800 HV; Coating Thickness: 2-4 microns; Thermal Stability: 750°s Celsius or 1350°s Fahrenheit.

These coatings and treatments when applied to the appropriate brite tool for a given application will accomplish some or all of the following:

• (1) increase tool life;
• (2) reduce down-time;
• (3) allow increased feed and speed rates, and;
• (4) reduce tooling costs per job/piece.
• Coated and Treated cutting tools offer substantial cost reductions.

The above noted coating benefits may be diminished due to:

• (1) an incorrect tool choice;
• (2) an incorrect coating choice;
• (3) the parts material;
• (4) the machine tools rigidity;
• (5) the choice of feeds and speeds;
• (6) the spindle and/or tool holder(s) run out, and;
• (7) the type and feed of coolant, if any.
