What is Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN) coating?













Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN; for aluminium contents higher 50 at.%) stands for a group of metastable hard coatings consisting of the metallic elements aluminium and titanium, and nitrogen.

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.

Coolant through port tools

Each of IC’s (India Carbide) coolant through port tools has coolant holes to either 3 or 5 of the tool's flutes because having an uneven number helps reduce chatter. Coolant lowers the surface temperature of the cutting zone making our port tools better equipped to deal with the extremely high temperatures that occur when machining a part. Lower temperatures in the cutting zone also make it less likely for chips to stick and through off the geometry of the tool, making for a perfectly balance long lasting tool.

Improving Quality in CNC Machine Environments: Reducing Cutting Tool Vibration



Quality is top of mind in every organization, but in the exacting world of CNC machining, it takes on a whole new meaning.  These companies must continuously eliminate any possible issues that could lead to work piece flaws. 

When it comes to ensuring quality in a CNC machine environment, one of the biggest factors a company needs to take into consideration is spindle vibration. 


how can a company eliminate vibrational issues from their CNC machine environments? Use a high speed machining (HSM) spindle that is dynamically balanced to comply with stringent ISO 1940/1 (balance quality requirements for rigid rotors) standards.  Dynamic balancing is an extra step that certain spindle manufacturers, take to ensure the quality of their products. HSM spindles that adhere to ISO 1940/1 standards are guaranteed to comply with the quality requirements.

There is an additional benefit to reducing vibration in CNC machine environments. When cutting tools are used under proper cutting conditions, the machining process is stable and the tool life is prolonged. This, of course, ensures more precision in the cutting process.   

From a workmanship perspective, a dynamically balanced HSM spindle is critical for ensuring top quality across the entire job.

Regardless of the cutting, any vibration created by a HSM spindle will degrade quality over the long run.  By choosing one that is dynamically balanced and compliant with ISO 1940/1 standards, the HSM spindle will ensure that you do not have returns because your work pieces do not meet customer specifications. 

How do you reduce vibration in your CNC machine? Let us know in the comments below.

India Carbide donates cutting tools to manufacturing programs #ICDonates



Pune, India – With great emphasis on education, training and strengthening the Indian manufacturing workforce, India Carbide has donated almost Rs.5,00,000 in metalworking tools to training centers, community colleges, technical programs and high schools throughout the Pune. The selection of tools included a variety of new and unused high quality solid-carbide end mills used for milling operations.

India Carbide is dedicated to closing the skills gap and ensuring the manufacturing workforce of tomorrow is well trained. Collaborating with and supporting learning institutions that specialize in hands-on shop training can aid in filling the growing number of jobs being vacated by many individuals retiring from the workforce. Plus, the training programs can retrain existing workers on technological advances that help to further overall manufacturing productivity.

“Throughout the year, we perform audits of our warehouse stock to clear out discontinued items, over-produced specials and other products that cannot or are unlikely to be sold in the future,” says Mahesh, technical support specialist at India Carbide. “In the past, we have recycled these tools to recoup a portion of our costs, but this year we decided that giving the entire Rs.5,00,000 worth of tooling to schools that are training the future workforce is really more valuable to us and to our industry.”

3 Tips on What Makes Quality Router Bits



So you think you are ready to start your next big project? You have your idea mapped out in your head, the materials are all laid out on the workbench and you’ve finally set aside time to see it all come to fruition. It is time to get to work, right? Well, not so fast. Before you start any project, it is important to make sure you have the proper tools to complete the job.

And the key to any successful project is confirming you are working with quality router bits. Router bits give shape to your project, so if they are off, so is your project. While there are many features you can look at to determine if you are working with dependable router bits, we narrow it down to three: material, shank diameter and manufacturer.



1. Router Bit Materials

What are the materials used to make your router bits? Most router bits are made from either high-speed steel (HSS) or carbide. Made from carbon steel, HSS bits have a high heat resistance, which allows the bits to maintain their strength longer. The alternative is carbide tip bit. Carbide tip bits are harder and can hold an edge longer than HSS bits. And when it comes to the lifespan of the bit, HSS bits simply can’t compete. According to Router Techniques: A Comprehensive Guide to Using Routers, carbide tips can last 80-90 percent longer than HSS bits.

While the carbide bit trumps HSS in most categories, it should be noted that you must handle and store carbide bits with care. Carbide tips are brittle, so it is important you take care of them accordingly. Handled correctly, you will find they stay sharp for a longer time while also providing a cleaner cut than HSS bits. All of which makes carbide bits the higher quality material and well worth the investment.

2. Router Bit Shank Diameter

There are two different diameters when it comes to shank size, ¼" and ½”. In most cases it is best to use a ½” diameter, because it is stiffer and stronger, which gives you less vibration and a smoother cut. There are some routers that only use ¼”, so check your router before getting started. But in most circumstances, you are going to rely on the stability and longevity of the ½”.

3. Router Bit Manufacturer

Where your router bit comes from is of great importance. Whether you are spending $3.00 or $3,000 on your bit, you want to make sure you are getting your money’s worth for your purchase. While there are several companies that produce good router bits, go with a name you can trust. India Carbide Router Bits comes up time-and-again. 

In the end, the India Carbide router bit was given an Excellent rating as well as being marked both Best Value and Best Overall. Made in the India, India Carbide's high quality micro-grain carbide bits have been a staple in the woodworking community for many years.

The expectations for quality router bits have been set. Take a look at the bits you are working with before you start your next project and see if they meet our minimum standards. Are you working with a carbide tip? Is the shank size ½”? And are you working with a reliable manufacturer, such as India Carbide. If you answered “No” to any of these questions, it might be time you visit indiacarbide.com and order a new set today.
