1.) Know your wheel speed: wheel speeds on machines vary and the most successful ceramic grinding operations are performed between 5500 & 6500 SFPM.
2.) Condition the wheel properly: Aluminum oxide dressing wheels produce the most open structure along the face of the grinding surface. A clean grinding surface is essential to successful ceramic grinding.
3.) Dress frequently: dressing the diamond wheel frequently provides a clean grinding surface and prevents the fine ceramic swarf from becoming trapped between the diamond particles.
4.) Ceramic is a tough material: Expect grinding pressure when grinding ceramic materials. It is also an insulator material which means that heat generated during the grind process is absorbed into the grinding surface.
5.) Follow the first four steps: You will find a greatly improved ceramic grinding process requiring little to no spark grind to produce a clean chip free edge.
We have the expertise and engineering staff to design custom solutions for diamond grinding wheels and tools.
When beginning a stone flooring restoration project, it is important to explore the condition of the work area. This allows a full understanding of the work that lies ahead and allows you to quote accordingly.
The best way to devise the correct procedure to achieve the agreed upon goal between you and your customer is to perform a test patch. It is my golden rule.
Testing a section of the stone, performed well before you are under the pressure of a contract, determines the best sequence of operations to achieve your customer’s anticipated results. It may also prevent you from performing unnecessary operations that may add value in your opinion, but that the customer does not understand. Or, it may be an opportunity to upsell your services if the customer agrees to pay extra because you educated him on the benefits of your proposal.
Testing allows you to predetermine how much time to spend on any given area, the diamond grit sequence which yields the best finishes and what buffing approach you can use to deliver the best finish using the simplest and shortest, yet most effective, sequence.
This simple trial of the diamond disks, typically done in a remote corner or dimly lit area, points to the level of finish you are capable of achieving on that particular job and ensures that the customer’s expectations are reasonable and realistic. Once performed, you will know your costs for the job and you can offer a proposal in full confidence that you can do what is needed.
The test patch also allows your customer to possibly realign his expectation to a more realistic approach and permits him to define the value that you are proposing, if different from the original intent. If you are lucky, another contractor may have also done a similar test patch and you will have something to compare your approach to; giving you a second chance to explore an alternative approach to meet different expectations. There may be a lot of differences between what your customer expects and actual possibilities. You just gave yourself another opportunity to explore options to discuss.
The test patch will also prevent the often asked request from the customer to do a little bit more work because his expectation changed, during which time you cannot demobilize the job, nor expect an agreed-upon payment. In cases where opinions differ, which is often when a defined target is not agreed upon, the test patch facilitates any conflict resolution that inevitably arises when expectations are not quantified or changed during the process. Then you are not at the mercy of someone else’s good will.
Always consider the test patch as the ultimate offer of an irrevocable standard against which you can compare and conclude the job. It’ll also allow your customer to feel good about the job you finished and confirm to him that you met his expectations. And in turn, he will feel good about paying you and likely recommend your services.
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.
