Abrasive Technology is excited to be exhibiting at the AeroDef Manufacturing show and conference from April 25th-27th in Long Beach, California.  As a manufacturing company we are looking forward to the Keynote Speech ” The Lure of New Materials and the Corresponding Reality of Manufacturing at Cost and Rate”.

At Abrasive Technology, we take a customer specific approach to the design and manufacture of material removal tooling for both cutting and grinding operations.  Whether your materials are metals, composites, ceramics and either leading edge or tried and true we strive to understand your business and process needs to provide a cutting tool and/or grinding wheel suited to you.  We custom manufacture Diamond and cBN grinding wheels/tools in a variety of bonds (brazed, plated, resin, metal) including on flexible substrates for finishing operations.  As well as PCD and PCNB cutting tools.

Stop by our booth 745 to meet Chad Wolfe, Joe Estrada and Brad Warnock, and allow us to start the conversation about your material removal needs, including meeting cost and rate targets.

Follow us on Twitter @AbrasiveTech, we will be live tweeting with #Aerodef

Cermet has been gaining popularity as a cutting tool all over the world. Its ability to withstand heat and its superior wear resistance make it a popular choice, especially for automotive applications. However, manufacturing cermet cutting tools is an altogether different experience. Here are a few tips to make grinding cermet cutting tools easier:


1.) Be patient. Cermet can not be ground at cutting rates that match carbide, or for that matter, even pure ceramic cutting tools. Cermets typically contain high levels of titanium as a binder and this material smears and loads diamond grinding wheels very rapidly. Cutting rates for cermets vary, but are commonly 50% to 75% that of carbide.


2.) Cermet collects rapidly on the surface of the diamond grinding wheel. Plan to dress the wheel frequently, as you are cleaning, not dressing away the Cermet.


3.) As with all materials, grinding wheel speeds will vary. Typical cutting speeds for cermets should be on the slower side, around 4500 SFPM.


4.) Coolant, coolant, coolant!! Always provide as much coolant and coolant pressure to the grinding zone as possible. Flushing the grinding zone with clean water soluble coolant will make the entire process of grinding cermet much easier.


5.) When all else fails, call Abrasive Technology, we have solutions.

Abrasive Technology welcomed students from The Ohio State University College of Engineering to its Central Ohio headquarters for a Shadow Day.  Students spent a hands-on day with AT engineers and team members learning about how a superabrasive tool is manufactured – from the order first being placed all the way to the finished diamond tool leaving the facility.

Students ended the day with a basic understanding of the electroplated bonding process, as well as their own personalized diamond saw blade.

Abrasive Technology and The Ohio State University share a commitment of excellence in the field of engineering and a passion for continuing education for a smarter manufacturing workforce.

A reoccurring challenge I confront when visiting customers using superabrasive OD (outer diameter) grinding wheels is variations in performance among wheels.  They want a consistent, sustainable (both in price and wheel life) wheel that grinds the same every time.

To produce an OD grinding wheel with a width of greater than 2”, individual 1” wheels are made and then glued together to form the desired width (with a goal of producing identical 1″ pieces for consistency).

However, consistency can prove challenging.  Assuming that the bond and superabrasive are properly prepared, the manufacturing process will likely include variations in:

  1. Mold setup when multiple molds are used
  2. Hot press equipment used
  3. Uniformity of pressure around the molded band
  4. Temperature ramp up & consistency
  5. Procedure of loading the molds
  6. Procedure of pressing the mold
  7. Bond density when compacting the loose powder matrix

Add the facts that different operators run machines at different times and there’s limited QC domumentation of the pressing cycle from wheel to wheel, it is easy to see that achieving absolute consistency in each 1″ piece is difficult.  And when multiple wheels are then glued together to make one large wheel, it’s no wonder machinists can encounter variations in wheel performance.

In order to solve these inconsistencies, I suggest using a solution that:

  • Is computer-controlled
  • Develops one uniform wheel rather than several individual wheels pressed together
  • Creates uniform density from OD to ID and from side-to-side
  • Relies on QC process documentation, which shows the precise process for each individual wheel. 
  •  A whole-system approach to ensuring consistency is your best bet when OD grinding.  By using a solution that follows these guidelines, you can be assured that each wheel is the same as the one that you ordered last time.

About a year ago I decided I needed reading glasses – my arms got too short.  I went to the big box discount store and picked a pair.  Yep, I could read better.  However, I still had sore eyes and headaches, so I made an appointment to visit an optometrist.  He checked my eyes and asked about my reading and computer use habits, then tailored a prescription exactly to my needs.  Now, I can not only read better, but I no longer have eye pain or headaches.

Choosing a grinding solution for your friction materials is no different.  You can purchase an off-the-shelf grinding wheel that will do the job, but to maximize your process and throughput, it’s best to work directly with the grinding wheel manufacturer to build a custom wheel.

Identifying your needs and goals – grinding cost (wheel price/parts ground), process output (parts/minute) and wheel set up time – will help narrow the field of choices.  Once the main conditions are identified, you’re on your way to an optimized grinding wheel solution.

drum Going with a custom wheel will allow you to choose between bond types — electroplated and braze bond -– to improve flexibility and function.  Electroplated grinding wheels can have a lower purchase price and are more easily re-plated (further reducing price) than braze bonds.  However, braze bonds can have longer wheel life and faster cutting speeds due to their higher bond strength and the ability to vary diamond concentration over a wide range.

Specifying the best wheel for a given grinding process also requires an understanding of the friction materials properties and the grinding process conditions.

Friction Materials Properties:  Friction materials are materials used to generate frictional forces.  There are two main categories — sintered materials and paper materials.  Sintered materials consist of a blend of various metal and non-metal powders that are pressed and heated to form a rough shape. This is often the first step in manufacturing a brake pad or brake shoe.  Paper products are combinations of pulp and resins more commonly used for clutch plates. Variation in materials and consolidation process conditions yield end products which require different grinding wheel constructions.

Grinding Process Conditions: Diamond abrasive grinding products, mainly drums, face wheels and saw blades, are used to successfully finish friction materials.  Diamond grinding wheel constructions are as wide ranging as the friction materials themselves.  Common variables include diamond type, diamond mesh size, amount of diamond per area, slotting and bond type (electroplated vs. brazed).

Delivering custom grinding solutions takes expertise and the ability to manufacture a wide range of grinding wheels. This process yields the best results when there is collaboration between the friction material manufacturer and the grinding wheel manufacturer.

An entrance washed in color.  Banners flying in the air.  Diamonds as far as the eye could see.

A crowd gathered.  There were big winners.  And others who left with only what they brought with them.

The Summer Olympics you ask?  No, it was the “We Champion Superabrasives” event at Abrasive Technology’s Lewis Center headquarters.

The event, attended by AT associates, highlighted products and processes from AT facilities across the globe for the aerospace, medical, general industrial, oil & gas, and stone markets.  AT Sales and Business Development associates served as hosts at each expo station, helping to make a connection between the tools the company produces and the resulting end products.

Associates mixed and mingled throughout the event, learning more about the extensive AT product line and enjoying prizes, a photo booth and refreshments.

Golden memories for all.
